-
Classification of SCIs
-
2 Broad Functional Categories:
-
1. Tetraplegia
- – Complete paralysis of all 4 extremities & trunk, including respiratory muscles
– Results from lesions of cervical cord
-
2. Paraplegia
- – Complete paralysis of all or part of trunk & both LEs
– Resulting from lesions of thoracic or lumbar spinal cord or cauda equina
-
Designation of Lesion Level
-
3 LEVELS:
-
Neurological Level
- The most caudal level of spinal cord w/normal (B) motor & sensory function
-
Motor Level
- The most caudal segment of spinal cord w/normal (B) motor function
- scoring: MMT ; myotomes
- – The key muscle defined as having intact innervation if it has a MMT score of 3/5 & the next most rostral key muscle exhibits 5/5
– For myotomes that are not clinically testable (C1-C4; T2-L1; S2-S5) the motor level is defined as the same as the sensory level
-
Sensory Level
- The most caudal segment of spinal cord w/normal (B) sensory function
- scoring: 0=absent, 1=impaired, 2=normal (light touch & pin prick)
-
Complete Injuries, Incomplete, & Zone of of Partial Preservation
-
Complete Injury
- – No sensory or motor function and the lowest sacral segments (S4 & S5)
– sensory & motor function at S4 & S5 = determined by anal sensation & voluntary external anal's painter contraction
-
Incompletel Injury
- Having a motor &/or sensory function below the neurological level, including sensory &/or motor function at S4 & S5
-
Zones of Partial Preservation:
- – This is where an individual has motor &/or sensory function below the neurologic level, but does not have function at S4 & S5.
– The areas of intact motor &/or sensory function below the neurological level = zones of partial preservation
-
ASIA Impairment Scale
-
Clinical Syndromes
-
1. Brown-Sequard Syndrome
- – Occurs from hemisection of spinal cord caused by penetration wounds
– Clinical features = asymmetrical
-
Ipsilateral to Lesion:
- – Loss of sensation in dermatome segment corresponding to level of lesion
– Due to lateral column damage = decreased reflexes, lack of superficial reflexes, clonus, & +Babinski sign
– Due to dorsal column damage = loss of proprioception, kinesthesia & vibratory sense
-
Contralateral to Lesion:
- Damage to the spinothalamic tracts = loss of sense of pain & temperature which begins several dermatome segments below the level of injury b/c lateral spinothalamic tracts ascend 2 -4 segments on the same side b4 crossing
-
2. Anterior Cord Syndrome
- FLEXION INJURIES
- – Frequently related to flexion injuries of cervical region==> damage to the anterior portion of cord &/or its vascular supply from anterior spinal artery
– Compression of anterior cord from fx, dislocation, or cervical disc protrusion
– Characterized by: loss of motor function (corticospinal tract damage) & loss of sense of pain & temperature (spinothalamic tract damage) below level of lesion
– (proprioception, kinesthesia & vibratory sense = preserved b/c they're mediated by posterior columns with a separate vascular supply from posterior spinal arteries)
-
3. Central Cord Syndrome
- HYPEREXTENSION INJURIES
- – Occurs from hyperextension injuries to cervical region
– Associated with congenital/degenerative narrowing of spinal cord
– Compressive forces==> hemorrhage & edema producing damage to most central aspect of cord
– characterized by: more severe neurological involvement of UEs (cervical tracts = more centrally located) than LEs (lumbar & sacral tracks = more peripherally located)
– Severity Varies: sensory impairments < motor deficits
– Pts=typically recoverability to ambulate with some remaining distal UE weakness
– + Surgical intervention
– (Preservation = sacral tracks, normal sexual, bowel & bladder fnx)
-
4. Posterior Cord Syndrome
- – Rare==> deficits of function served by posterior columns
– Characterized by: loss of proprioception & epicritic sensations (2-pt discrim, graphesthesia, sterognosis) below level of lesion
– Wide-based steppage gait
– In past = seen w/Tabes Dorsalis (cond. found w/late-stage syphilis)
-
5. Sacral Sparing
- – An incomplete lesion where the most centrally located sacral tracks are spared
– Varying levels of innervation from sacral segments remain intact
– Clinical signs: perianal sensation & external anal spanker contraction= often the 1st signs that a cervical lesion is incomplete
-
6. Cauda Equina Injuries
- These lesions are peripheral nerve (LMN) injuries
-
Thus they have the same potential to regenerate as peripheral nerves elsewhere in body BUT full return of innervation isn't common b/c:
- 1. There is a large distance between lesion & point of innervation
2. Axonal regeneration may not occur along the original distribution of nerve
3. Axonal regeneration may be blocked by glial-collagen scarring
4. The end organ may no longer be functioning once reinnervation occurs
5. The rate of regeneration slows & finally stops after about 1 yr
-
Mechanisms of Injury Table 23.2 p. 942
- – Most frequently occurs from indirect forces produced by movement of the head & trunk & must often from direct injury to a vertebra
– Highest frequency of injury: btwn C5 & C7; T12-L2
- Flexion Force
- Compression Force
- Hyperextension Force
- Flexion-Rotation Force
- Shearing Force
- Distraction Force
-
Clinical Manifestations
-
Spinal Shock
- – Occurs immediately after SCI = pd of areflexia
– Believed to result from very abrupt w/d of connections btwn higher centers & spinal cord
-
Characterized by:
- – Absence of all reflex activity
– loss of Bulbocanvernosus Reflex
– loss of Cremasteric Reflex
– delayed plantar response
– plasticity
– loss of sensation & motor function
All below the level of lesion, lasting several days to several weeks
-
1st Indicator that spinal Shock is Resolving=Presence of a Pos Bulbocavernosus Reflex
- Digital Rectal Exam: reflex is elicited by pressure applied to glans penis/glans clitoris or by intermittently tugging on indwelling catheter. If pos, a reflex contraction of anal sphincter around examining digit will be evident
-
Motor & Sensory Impairments
- – Complete or partial loss of muscle function below level of lesion
– Impaired or absent sensation below level of lesion
– Clinical presentation depends on specific features of lesion: neurological level, the completeness of lesion, & symmetry of lesion (transverse or oblique
-
Autonomic Dysreflexia
- – Pathological autonomic reflex that typically occurs in lesions above T6 (above sympathetic splanchnic outflow) but as been reported at T7 & T8
– The episodes gradually subside over time & relatively uncommon but not rare, 3 years following injury
– Seen in patients with both complete & incomplete lesions
– Produces an acute onset of autonomic activity from noxious stimuli below level of lesion that reach the lower spinal cord (lower thoracic & sacral) & initiate a mass reflex response resulting in elevated BP
– The vasomotor center is the region to readjust peripheral resistance but w/ SCI, impulses from the vasomotor center can't pass the site of lesion to counteract the HTN by vasodilation (HTN can persist if not treated promptly and death may result)
-
Initiating Stimuli
- MOst common Cause= Bladder Distention (Urinary Retention)
-
Other Precipitating Simuli:
- Rectal distention, pressure sores, urinary stones, bladder infections, noxious cutaneous stimuli, kidney malfunction, urethral or bladder irritation, & environmental temperature changes; reported following passive stretching at hip
-
Sxs
- Include: HTN, bradycardia, headache, profuse sweating, increase spasticity, restlessness, vasoconstriction below level of lesion, vasodilation above level of lesion, constricted pupils, nasal congestion, piloerection (goose bumps), & blurred vision
-
Intervention
- – Treated as medical emergency
– if lying flat bring to sitting position to lower BP
– due to bladder distention, drainage system should be examined immediately
– release clamps catheter
– drainage tubes should be checked for internal or external blockage or twisting
check patient's body for irritating stimuli
– if symptoms don't subside immediately contact medical/nursing (A)
– bladder irrigation (a higher – level block may exist)
– removal & replacement with the a catheter
– examination for bowel impaction
– drug therapy (antihypertensives)
-
Postural Hypotension
- – Is a decrease in BP that occurs when assuming any wrapped/vertical position (i.e. lying to setting; sitting to standing)
– caused by loss of sympathetic vasoconstriction control
– tend to occur more frequently with lesions of the cervical & upper thoracic regions
-
Sx:
- – Reduced cerebral blood flow & decreased venous return to heart==> lightheadedness, dizziness, or fainting
– edema (pitting) of legs, ankles & feet 2°
-
Minimize Effects:
- – Cardiovascular system should be allowed to adapt gradually by a slow progression to vertical position: elevation of head of bed & progress to a reclining w/c w/ elevating leg rests & use of tilt table
– use of compressive stockings & and abdominal binder
– pharmacological therapy
– the cardiovascular system over time, gradually reestablishes sufficient vasomotor tone to allow assumption of vertical position
-
Impaired Temperature Control
- – Damage to spinal cord = inability of hypothalamus to control cutaneous blood flow or level of sweating which results in loss of internal thermal regulatory responses
– can't shiver, vasodilation doesn't occur in response to heat nor does vasoconstriction in response to cold
– absence of thermal regulatory sweating which eliminates normal evaporative cooling effects of perspiration and warm environments which is often associated with excessive compensatory diaphoresis (perspiration) above the level of lesion
– these changes = body temperature being significantly influenced by external environment
– more frequent problem with cervical lesions
– tetraplegia Pts. typically experience LT impairment of body temp regulation
-
Respiratory Impairment
- – With high spinal cord lesions between C1 & C3, phrenic nerve innervation & spontaneous respiration are significantly impaired or lost, resulting in the requirements of an artificial ventilator or phrenic nerve stimulator to sustain life
– lumbar lesions = full innervation of both primary (diaphragm) & secondary (neck, intercostal & abdominal) respiratory muscles
– all patients with tetraplegia & those with high-level paraplegia demonstrate some compromise in respiratory function
-
Muscles:
-
Primary Muscles of Inspiration:
- Diaphragm & external intercostals
-
Accessory muscles of REspiration assist w/elevation of ribs:
- SCM, Trapezii, Scaleni, Pec Minor & Serratus Anterior
-
Primary Muscles of Expiration:
- Abdominals & Internal Intercostals
-
Paralyses:
-
Intercostals:
- Decrease chest wall expansion & a lowered inspiratory volume
-
Abdominals & Internal Intercostals
- Significant decreases in expiratory efficiency
-
Abdominals
- Loss of support (maintaining intrathoracic pressure for effective respiration; supporting abdominal viscera; assisting in maintaining position of diaphragm; pushing diaphragm upward during forced expiration), causing the diaphragm to assume an unusually low position in the chest resulting in a decrease expiratory reserve volume that subsequently decreases cough effectiveness & ability to expel secretions
-
External Obliques
- Also influences expiration and with higher-level lesions further reduction in the patient's ability to cost & expel secretions occur all of which make the patient susceptible to retention of secretions atelectasis & pulmonary infections
- Paralysis also results in development of an altered breathing pattern characterized by flattening of the upper chest wall, decrease chest wall expansion & a dominant epigastric rise during inspiration
-
Spasticity
- – Results from release of intact reflex arcs from CNS control & characterized by hypertonicity, hyperactive stretch reflexes & clonus
– occurs below the level of lesion after spinal shock subsides
– is a gradual increase in spasticity during the first 6 months & plateaus at 1 year after injury
-
Tx:
- Drug Therapy
-
Injected Chemical Agents:
- Peripheral Nerve Blocks
- Chemical injection is used peripherally to selectively block transmission of the motor nerve to a spastic muscle & interrupt the intact reflex arc peripherally
- Temp reduction in spasticity & include:
- Phenol Peripheral Nerve Blocks
- Phenol Motor Point Blocks
- Intrathecal Injections
- A central (w/in spinal canal) chemical injection is used
-
Surgical Approaches:
- Myotomy
- Neurectomy
- Tenotomy
-
Radical Neurosurgical Interventions=destructive approaches=permanent
- Rhizotomy
- Myelotomy
-
Bladder Dysfnx Table 23.3 p. 947
- – UTI=among most common
– during spinal shock, urinary bladder = flaccid; all muscle tone & bladder reflexes are absent
-
Micturition
- – Spinal integration Center for micturiction- CONUS MEDULLARIS
– primary reflex control originates from S2-S4 w/in Conus Medullaris
-
Following Spinal Shock 1 of 2 types of Bladder Conditions will Develop:
-
Spastic or Reflex (automatic) Bladder (UMN Lesion)
- – Spastic bladder contracts & reflexively empties in response to a certain level of filling pressure
–Occurs w/SCI above micturition reflex center (S2-S4), gen involving T11-T12 injury or above
– reflex arc is intact (intact micturition reflexes)
– reflex emptying may be triggered by manual stimulation techniques
- Prognosis for bladder control:
- Bladder training is aimed at using micturition reflexes & "trigger" stimulus to establish planned reflex voiding
-
Flaccid or Nonreflex (autonomous) Bladder (LMN Lesions)
- – Is flaccid b/c there's no reflex action of the detrusor muscle
– Occur w/SCI @ micturition reflex center (S2-S4), gen involving T12 injury or below
– Loss of micturition reflexes
– Can be emptied by increasing entropy nominal pressure via Valsalva or Crede maneuver (manually compress lower abdomen)
- Prognosis for bladder control:
- Unable to establish reflex voiding, intermittent bladder Radiation may be best method for bladder mgmt
-
Bladder Training Programs p. 946
-
Primary Goal:
- allow pt. to be free of catheter & to control bladder fnx
-
Spastic/Reflex Bladder:
- Intermittent Catheterization
- estab reflex bladder emptying @ regular, predictable intervals in response to a certain level of filling
-
Flaccid/Nonreflex Bladder:
- Timed Voiding Program
- Find the pattern of incontinence and compare it to the patterns of intake to make a schedule so bladder gradually becomes accustomed/trained to empty at regular, predictable intervals
-
Bowel Dysfnx Table 23.4 p. 948
-
Spastic/Reflex Bowel
- Lesions above conus medullaris
-
Flaccid/Nonreflex Bowel

-
Spastic/Reflex Bowel Mgmt:
- Suppositories
- Digital Stimulation
-
Flaccid/NonReflex bowel Mgmt:

- Orgasm
-
Female Response
- Menstruation
- Fertility and Pregnancy
-
Indirect Impairments & Complications
-
3 Common 2° complications:
-
Pneumonia (34.3%)
- – Week &/or paralyzed muscles of inspiration = reduced ventilation of lungs
– inadequate/absent strength of coughing muscles = difficult to clear secretions
– inability to clear secretions = buildup of fluid in lungs ==>atelectasis & pneumonia
-
Pressure Ulcers (33.5%)
- 2 Most Influential Development FActors
- 1. Impaired Sensory Fnx
- 2. Inability to Make Approp. Positional Changes
- Other Factors:
- 1. Loss of vasomotor control ==> lowering of tissue resistance to pressure
2. Spasticity ==> shearing forces between surfaces
3. Skin Maceration form exposure to moisture (urine)
4. Trauma (adhesive tape/sheet burns)
5. Nutritional Deficiencies ==> reduce tissue resistance to pressure
6. Poor gen skin condition
7. 2° Infections
-
DVT (15%)
- – Results from development of a thrombus within a vessel
– most frequently occurs within the first 2 months following injury
– risk heightened with age & prolonged pressure
– formation of thrombus results in thrombophlebitis with characteristic clinical features of local swelling, erythema & head; which are signs similar to those of early ECTOPIC BONE FORMATION & long bone fx
- Most Important Contributing Factor:
- Loss of normal pumping mechanism provided by active contraction of LE musculature
- which slows blood flow==>high conc of procoagulants (thrombin) to develop in localized areas==>predisposition to thrombus formation
- Other Contributing Factors:
- – Prolonged pressure
– loss of vasomotor tone & immobility
– immobility leading to venous stasis, sepsis, hypercoagulability & trauma
- Mgmt:
- – Prevention
– prophylactic anticoagulant drug therapy initiated following acute onset & continued for 2-3 months or up to 6 months
– turning program designed to avoid pressure over large vessels
– PROM exercises
– elastic support stockings
– positioning of LEs to facilitate venous return
- Contractures
-
Heterotopic Ossification
-
HO vs MO
- Heterotopic Ossification
- osteogenesis in soft tissues
- Myositis Ossificans
- results from injury to a muscle & characterized by bony deposits w/in muscle tissue
-
Etiology Theories:
- Tissue hypoxia 2° to circulatory stasis, abnormal calcium metabolism, local pressure, & Michael trauma related to overly aggressive ROM exercises
-
Location:
- – Always extra articular & extracapsular
– may develop in tendons, connective tissue between muscle, aponeurotic tissue, or peripheral aspect of muscle
– typically occurs adjacent to large joints: HIPS & KNEES=most common
-
Signs & Sx
- Early Sx
- Resemble those of thrombophlebitis, including swelling, decreased ROM, erythema & local warmth near a jt
- Early Onset
- Characterized by serum alkaline phosphatase levels & negative radiographic findings
- Later clinical stages:
- Soft tissue swelling subsides & radiographic findings are positive
-
Mgmt
- – Pharmacological therapy: diaphosphates-inhibit formation of calcium phosphate & prevent ectopic bone formation
– Physical therapy: maintain ROM & prevent deformity
– Surgery: resection of ectopic bone
-
Pain
-
Traumatic Pain
- – Related to extend & type of trauma sustained & structures involved following acute traumatic injury
– subsides with healing in ~ 1 – 3 months
- Mgmt:
- – Immobilization
– Analgesics
– TENS
-
Nerve Root Pain
- – Occurs at or near side of cord damage
– Caused by acute compression or tearing of nerve roots, arise 2° to spinal instability, periradicular scar tissue & adhesion formation, or improper reduction
– "Sharp, Stabbing, Burning, or Shooting" pain following dermatomal pattern
– most common in cauda equina injuries
- Mgmt:
- Conservative management:
– Pharmacological therapy
– TENS
Cervical interventions:
– Nerve root sections (neurectomy)
– Posterior Rhizotomies
-
Spinal Cord Dysesthesias
- – Diffuse & don't follow a dermatome distribution
– Occur in body parts that otherwise lacked sensation & are often described by patient as Burning, Numbness, Pins & Needles, or Tingling feelings, and occasionally involving abnormal proprioceptive sensations
– "Phatom Pains"
– Etiological theories: scarring and distal end of severed spinal cord
- Mgmt:
- – Is resistant to treatment
– Acknowledged complaints as real & educate on legitimacy of pain
– Gentle handling & careful positioning
– Pharmacological mgmt: Tegretol, Dilantin
– Narcotic analgesics = discouraged==>addiction
-
Musculoskeletal Pain
- – May occur above the level of lesion & for equally involved shoulder joint
– Causes: faulty positioning, inadequate ROM, tightening of joint capsule & surrounding soft tissue structures; muscle imbalances around join, inflammation, UE fx
- Mgmt:
- – Prevention of 2° shoulder involvement
– Regular program of ROM exercise
– Positioning program designed to facilitate full-motion at shoulder
-
Osteoporosis & Renal Calculi
- – b/c osteoclasts > osteoblasts ==> greater susceptibility to fx and due to this resorption, there are large concentrations of calcium present in the urinary system (hypercalciuria), creating a predisposition to stone formation
– Highest incidence of bone mass changes & hypercalciuria-1st 6 mos post SCI
– Contributing Factors: immobility & lack of stress placed on skeletal system through dynamic WB activities
- Mgmt:
- – Dietary management: calcium-restricted foods, vigorous hydration, high-protein foods (NO dairy high in calcium)
– Early & continuing WB activities
– Risk of colliculus formation = reduce by prevention of UTIs Emerson careful maintenance of bladder drainage to prevent urinary stasis
-
Prognosis
- – Potential for recovery is directly related to extent of damage to spinal cord &/or nerve roots
– Prognosis is initiated after spinal shock has subsided & is guided by whether or not the lesion is complete
-
3 Factors Affecting Prognosis:
- The degree a pathological changes imposed by the trauma
- The precautions taken to prevent further damage during rescue
- Prevention of additional compromise of neural tissue from hypoxia & hypotension during acute management
-
For Complete Lesions:
- No motor improvement is expected other than that which may occur from nerve root return
-
For Incomplete Lesions:
- – Good prognosis for significant recovery of motor function
– Improvements begin almost immediately following cessation of spinal shock
– Many have some progressive improvement of muscle returned during the first several months following injury with further recovery expected at same rate, or a slightly slower rate
– Rate of recovery will decrease & plateau will be reached where there will be no more additional recovery to be expected
-
Acute Medical Mgmt Phase
-
Emergency Care
- – At the accident scene once SCI is suspected, ever should be made to avoid both active & passive movement of spine
– Helpful strapping patient to spinal backboard or full body adjustable backboard, use of supporting cervical collar & assistance from multiple personnel
– Administration of high doses of Methylprednisolone w/in 3-8 hrs of injury for 24-48 hrs to improve motor & functional recovery
– @ ER: complete neuro exam, radiographic & imaging; restoration of vertebral alignment & early mobilization of fx site; cardiac, hemodynamic & respiratory status closely monitored; insert urinary catheter; 2° injuries addressed; early reduction & fixation of unstable spinal fx
-
Fx Stabilization
-
Closed Reduction via Traction Devices
- Tongs (attached to outer skull)
- Halo Devices
-
Surgical Decompression & Stabilization
- For patients with deteriorating neurological status, instability following closed reduction, unstable fx site, & (B) facet dislocation
-
Operative Tx
- – Usually consists of an anterior or posterior arthrodesis w/plate or rod fixation
– can occur as early as w/in first 24 hrs postinjury
-
Immobilization
- Occurs following reduction of the fx site to allow for healing
-
Tongs
- Purpose? Used When?
- Used primarily as a temporary mode of skeletal traction w/ replacement using a Halo device
- – Tongs/calipers=inserted laterally on outer table of skull.
– A traction rope is attached to the skull fixation and while pt is in supine, the rope is threaded through a pulley or traction collar with weights attached distally & freely hanging w/o touching floor
-
Halo Devices
- Advantages:
- – Assist in reducing 2° complications of prolonged bed rest
– Permit earlier progression to upgrade activities
– Allowed earlier involvement in a rehab program
– Reduce length & cost of hospital stay
- – Commonly used to mobilize cervical fxs
– Consists of a halo ring with 4 steel screws attached directly to the outer skull. It is attached to a body jacket/best by 4 vertical steel posts
– Contraindicated with severe respiratory involvement
– Left in place until radiographic findings indicate stability (~12 wks)
– After removal, a cervical orthosis is applied until unrestricted movement is allowed (~4-6 wks)
-
Turning Frames & Beds
- Frames are now used primarily as a temporary method of immobilization
- Benefits:
- – Allow positional changes while maintaining anatomical alignment of the spine
– Turning can be accomplished without interruption of the cervical traction
- Cons:
- – Positioning is limited to prone & supine
– Can't accommodate obese pts & unsuitable for unconscious pts
- How It Works:
- – Consists of an anterior & posterior frame attached to a turning based
– Turning from supine position: anterior frame is placed on top of patient. Circular ring clamps in place to secure 2 frames during turning. Safety straps provide additional security
– Rotation to prone position: by manually turning the 2 frames as a unit. Uppermost frame is then removed. Return to supine position.
-
Thoracolumbosacral Orthoses (TLSO)
- – Used to mobilize the spine in patients with thoracic or lumbar injuries
– The plastic body jacket functions to mobilize the spine & allow earlier involvement in rehab program
– Body jackets are typically bivalve to allow for removal during bathing & skin inspection
-
PT Exam
-
Respiratory Exam
-
Fnx of Respiratory mm.
- Diaphragm, Abdominals, Intercostals; & RR noted
-
Chest Expansion
- – Circumferential measurements:@ level of axilla & xiphoid process;
– The diff in measurements btwn max exhale & max inhale
– Norm expansion= 2.5-3 in. @ xiphoid process
-
Breathing Pattern
- – Manual palpation over chest & abdominal region & observation
– Pay close attention to use of accessory neck muscles & alteration in breathing pattern when pt is talking/moving
-
Cough
- 3 Cough Classifications
- Functional:
- strong enough to clear secretions
- Weak Functional:
- adequate force to clear upper respiratory tract secretions in small quants
- Nonfunctional:
- unable to produce any cough force
-
Vital Capacity
- – Take w/handheld Spirometer
– Can be used as baseline for defining respiratory muscle weakness
-
Integument
-
Areas Most Susceptible to Pressure in Recumbent:
- Supine
- Occiput, scapulae vertebrae, elbows, sacrum, coccyx, heels
- Prone:
- Ears, shoulders (ant), iliac crest, male genital region Patella, dorsum of feet
- Sidelying:
- Ears, shoulders (lat), greater trochanter, head of fibula, knees (medial), lateral malleolus Medial malleolus (malleoli contact)
-
Sensation
- Place particular emphasis on pin prick, light touch, & proprioceptive responses
- **Sensory level of injury may not correspond to the motor level of injury
- Tone & DTR
-
DTRs
- C5 – biceps
C6 – ECRL
C7 – triceps
L3 – quadriceps
S1 – gastrocnemius
- MMT & ROM
-
Functional Status
- although done in active rehab stage, initial screen is fine but be aware of contraindications & precautions to movement necessitated by healing & potentially unstable fx sites
-
PT Intervention
-
Respiratory Mgmt
-
3 Primary Goals:
- Improved Ventilation
- Increased Effectiveness of Cough
- Prevention of Chest Tightness & Ineffective Substitute Breathing Patterns
-
Treatment Activities:
- Deep-Breathing Exercises
- To facilitate Diaphragmatic movement & increase vital capacity:
- Inspiration
- apply light pressure just below sternum
- Expiration
- apply light pressure over the thorax w/hands spread wide
- Glossopharyngeal Breathing
- – Approp. for or patients with high-level cervical lesions
– Pt is instructed to inspire small amounts of air repeatedly, using a sipping or gulping pattern thus utilizing available facial & neck muscles thereby allowing enough air to gradually be inspired to improve chest expansion despite paralysis of the primary muscles of respiration
- Airshift Maneuver
- – Provides patient with independent method of chest expansion
– Closing glottis after maximum inhalation, relaxing diaphragm, & allowing air to shift from lower to upper thorax
– Can increase chest expansion by 0.5-2 inches
- Strengthening Exercises
- Progressive resistive exercises:
– Manual contact over epigastric area below xiphoid process or by use of weights
- Assisted Coughing
- &– Manual contacts over epigastric area
– PT pushes quickly in an inward & upper direction as pt attempts to cough
- Abdominal Support
- – Use of abdominal corset/binder = 4 pts w/proturding abdomen allowing diaphragm to "sag" into poor pos. for fnx
- Benefits:
- – Will support abdominal contents & improve resting position of diaphragm
– (2°): Maintain intrathoracic pressure & degrees postural hypotension
- Stretching
- stretch pecs & other chest wall muscles to facilitate mobility & compliance of thoracic wall
- Others:
- – Intermittent positive pressure breathing: assist in maintenance of lung compliance
– Modified postural drainage & percussion techniques: to assist with mobilizing & eliminating secretions
-
ROM & Positioning
-
Contraindications:
- Paraplegia
- Motion of the trunk & some motions of the hip
*Avoid: SLR more than 60° & hip flexion beyond 90° (during combo hip & knee flexion)
- Tetraplegia
- Motion of the head & neck pending orthopedic clearance
- In prone, position Pt. out of usual position of comfort, in which there is IR, ADD & Ext of shoulders, elbow flex, forearm pronation & wrist flexion
-
ROM:
- exercises should be completed in prone & supine if possible
- – Some joint benefit from allowing tightness to develop in certain muscles to enhance function
– some muscles require a fully lengthened range
– Selective Stretching: process of under stretching some muscles & full stretching of others to improve function
-
Gadgets:
- Positioning Splints
- for wrist, hands fingers to maintain alignment for fnxal activities or future dynamic splinting
- Ankle Boots
- to maintain alignment & prevent heel cord tightness & pressure sores
- suspends heel in space & distributes pressure evenly along lower leg
- Sandbags/Towel Rolls
- to maintain position of neutral hip rotation
-
Selective Strengthening
- – During acute phase certain muscles must be strengthened very cautiously to avoid stress at fx site
– Acute phase = emphasize (B) UE activities b/c these will avoid asymmetric, rotational stresses on the spine
– Early involvement in functional activity should be stressed (intrinsic value + progressive strengthening benefit
-
Forms of Strengthening Exercises in Early Phase:
- – (B) Manually resisted motions in straight planes
– (B) UE PNF patterns
– Progressive resistive exercises using cuff wts/dumbbells
*Biofeedback training=useful adjunct
-
w/Tetraplegia
- Emphasis should be placed on strengthening:
– anterior deltoid
– shoulder extensors
– biceps
– lower trapezius
– radial wrist extensors, triceps & pectorals = important in improving functional capacity
-
w/Paraplegia
- All UAE musculature should be strengthened with emphasis on the following which are req'd for transfers & ambulation:
– shoulder depressors
– triceps
– latissimus dorsi
-
Orientation to the Vertical Position
-
Cleared for upright Activities when:
- Once radiographic findings have estab'd stability of fx site, or early fx stabilization methods are complete
-
Techniques/Gadgets:
- – Gradual acclamation to upright posture to minimize postural hypotension
– use of abdominal binder & elastic stockings: retarded venous pooling
– In early upright positioning, elastic wraps placed over elastic stockings are often used
- Slowly elevating head of bed ==>Reclining or Tilt-in-Space W/C w/elevating leg rests (or just a tilt table)
-
Active Rehab Phase
- See Table 23.6 p. 961 for Functional Expectations for young SCI Pts.
-
PT Exam
- Exams & procedures completed during acute phase will continue here at irregular intervals with more complete testing of MMT, ROM, & functional skills now more mobility is allowed
-
What to examine:
- – Functional ability
– Wheelchair Skills: setting & releasing will locks, removing foot rest & armrest, propelling w/c on level surfaces, performing wheelies, ascending/descending curbs etc
– Seating & wheelchair to determine most appropriate seating syst & w/c for Pt.
-
Frequently Used Standardized Outcome Measures

Functional Independence Measure (FIM)
- – Measures functional ability in a variety of ADLs
– reliable & valid
-
The Wheelchair Skills Test
- – Examine a manual w/c user's skills in performing 57 representative w/c skills
– Can be used as diagnostic measured to determine which w/c skills need to be addressed & document improvement
- Diff skills are categorized according to 3 Levels that reflect difficulty & the setting in which the skills are most often used:
- 1. Indoor
2. Community
3. Advanced
- The Walking INdex for Spinal Cord Injury (WISCI)
- The Spinal Cord Injury Functional Ambulation Inventory (SCI-FAI)
-
PT Intervention
- – Emphasis = maximizing functional independence
– Initially = basic skills; progression = skills necessary for work, home & community reentry
– If patient is unable to accomplish a specific functional task independently they must be able to instruct a personal-care attendant on how to perform the task
-
Continuing Activities
- – Continuation from acute phase (respiratory management, ROM & positioning) & expanded program of resistive exercise for all muscles that remain innervated
– development of motor control & muscle reeducation techniques directed appropriate muscles (based on lesion level) = indicated
– emphasis: regaining postural control & balance by substituting upper body control & vision (per loss proprioception)
– focuses on improved cardiovascular response to exercise the use of interval training using an UE aerobic activity
- Skin Inspection
-
Mat Programs
-
General Info:
- – Sequence of activities typically progresses from achievement of stability with any posture & advances through control mobility to skill in functional use
– early activities: bilateral & symmetrical. A progression is then made to weight shifting & movement within the posture
– complete mastery of an activity is not always necessary before moving on to the next
– several components of the map progression will be worked on concurrently
– should be initiated as soon as patient is cleared for activity
-
Benefits:

- head moves forward, butt moves backwards
-
Prescriptive Wheelchair
-
Types of W/Cs:
- Manual w/c:
- 2 Basic Frames
- Folding Frame
- – For patients who plan to transfer into a car
– incorporate a below seed crossbar & generally provide a smoother ride on uneven surfaces
– con: more movable parts causing it to be less energy-efficient & slightly less lateral stability
- Rigid Frame
- – More energy-efficient, usually lighter weight; adjustable seat-to-back angle
– more difficult to store and car
– allows placement of w/c into Emerson out of a car as components rather than as 1 large unit
– generally less smooth riding on an even surfaces (some have shock absorbing springs)
- – Need intact triceps function to independently propel
– for Pts. With C6 or C-5 level injury or lower
- Powered w/c
- – for Pts. w/ cervical injuries above C5/C6
– indicated for all patients with C4 lesions & above although patients with C-5 lesions may elect to use power w/c for community mobility
– a tilt-in-space or reclining seating system provides improved postural control & it allows the user to independently perform pressure relief
- Powered Manual w/c Mix:
- PAPAW: Push rim Activated Power Assist Wheelchair
- – Is a manual w/c to which power assist wheels have been added
– user applies force to the pushrims and the motor is activated providing assistance to the wheels
– less energy, lower stroke frequency, & less shoulder ROM (when propelling)
– beneficial for individuals with mid to lower level cervical injuries (C5-C6) who may not have the endurance or string to use a manual w/c all the time
-
General W/C Prescription Guidelines:
- Seat Depth
- 1-2 in. back from popliteal space
– to allow even wt distribution on thighs & prevent excessive pressure on ischial tuberosities
- Floor-to-Seat Height
- – Needs to allow adequate ( 2 in.) clearance from floor to foot pedals
– can provide slightly greater than a 90° angle at the hips
- Back height
- Seat Width & Depth
- Pt. Should be fitted in the narrowest chair possible, but have adequate space between the lateral edges of the thighs & w/c armrests or wheels to avoid skin irritation
- Heel Loops/Toe Loops on Footrest; Pelvic Belt; Elevating Footrest
- Removable Armrests & Detachable Swing-away Leg rests
- Additional Features:
- – Enlarged release mechanisms on the foot rests
– a friction surface on the hand rims
– break extensions
– anti-tipping devices
– grade aids (which decrease backward movement of the chair while ascending inclined surfaces)
-
Wheelchair Skills
- – Management of the breaks, arms & pedals = crucial for transfer activities
– use of cycling gloves will protect skin & improve patients grip on hand rims
– be instructed on how to perform wheelies which is required for independent curb climbing
– using the wheelchair skills test & wheelchair skills training program which is designed to improve manual wheelchair user performance & safety
– instruct patient and pressure relief techniques from a sitting position
-
Ambulation After SCI
-
Gait Training for Individs w/Complete SCI

– learn it in a new, compensatory methods of walking
- Orthotic Prescription
- KAFOs
- – Req'd for pts w/complete thoracic lesions
– ankle joint usually locked and 5° – 10° of DF to assist hip ext @ heel strike
- Types:
- Conventional (p 979)
- Reciprocating Gait Orthosis (RGO) p. 980
- – Allows for unilateral leg advancement & reciprocating gait pattern
– a 2 or 4 point gait pattern can be used in combo with crutches or a reciprocating Walker
- AFOs
- appropriate for pts w/lower-level lesions (L3 & below)
- Gait Training Strategies p. 980-982
- – A swing-through type of gait pattern should be the ultimate goal for functional emulators with KAFOs
– important to stress a smooth, even cadence
- Putting on & removing Orthoses
- STS Activities
- Trunk Balancing
- Push-Ups
- Turning Around
- Jack-knifing
- – Entails controlling the pelvic position using UE support & positioning the head & shoulders forward ahead of the pelvis
– this is an unstable position, & the patient must be taught recovery to overcome and/or to prevent this from happening during ambulation
- Ambulation Activities in // Bars
- – 4 & 2 point gaits req hip flex or hip hiking
– Pts. w/high lesions may learn this movement using secondary hitchhikers (internal & external obliques & latissimus dorsi)

Locomotor Training for Individs w/Incomplete SCI
- Train Like You Walk
- Translates into the following practical training guidelines:
– the LEs are maximally loaded for WB, minimizing or eliminating loading of the arms
– the posture, trunk, pelvis & limb kinematics are coordinated & specific to the task of walking
– compensatory strategies for movement (i.e. hitchhiking) are minimized or eliminated
- BWS Syst & TM:
- – Provide safety, support, task specific repetition of walking and present a means to challenge & progress abilities
– affords control of the amount of lower limb loading, assists and upright posture & balance, & allows control of the speed of walking; allows for manual assistance as needed
– PT must determine what elements of practice are consistent with task of walking & what elements are inconsistent with task of walking and choose the parameters accordingly
– parameters: adjusting load, treadmill speed, & amount of manual assistance
– intensity is required; achieving 20 – 30 minutes of total stepping time is recommended, with increasing duration of each training about
– transferring skills: daily examination of walking abilities overground & on treadmill with BWS is necessary. Modifying parameters of training in both environments will challenge the use of new skills, reinforce new parameters & independence, & afford information for goal setting across environments
- Current Literature p. 987:
- – Indicates that following locomotor training that Incorporated use of a BWS system & TM in subacute & post acute rehab that persons with incomplete SCI improved in balance, gait speed, endurance, stairclimbing & Independents
– persons with incomplete SCI performing LT during acute rehab has also been established
