Concorde Career CollegePhysical Therapist Assistant PTA 150: Fundamentals of Treatment II Day 13 & 14 Spinal Cord Injury Concorde Career College
Lesson Objectives • Describe the pathophysiology of spinal cord injury • Describe physical and neurological disorders associated with spinal cord injury • Identify functional outcomes for patients with spinal cord injury at various spinal cord lesion levels • Describe physical therapy treatment interventions for patients with spinal cord injury Concorde Career College
Spinal Cord Injury • 11,000 new SCI cases in the US yearly • Etiology: traumatic vs. nontraumatic • Traumatic is most common – MVA, fall, GSW • Nontraumatic – usually result from disease or pathological influence • Vascular malfunctions (AVM, thrombosis, embolis…) • Vertebral subluxations (secondary to RA or DJD) • Infections such as syphilis or transverse myelitis • Spinal neoplasms • Multiple sclerosis, amyotrophic lateral sclerosis Concorde Career College
Mechanism of Injury • Indirect force produced by head or trunk movement • Flexion force (head-on collision; blow to back of head) • Lateral flexion force • Compression force (diving, falling objects…) • Hyperextension force (strong rear-end collision, fall hitting chin …) • Flexion and rotational force (rear-end collision with passenger rotated towards driver) • Direct force trauma Concorde Career College
Types of Injury • Complete (ISNCSCI) • No motor or sensory functions is preserved in the sacral segments S4 to S5 (anal sensation and voluntary external and sphincter contraction) • Partial/Incomplete • Partial motor or sensory functions below the level of lesion Concorde Career College
Spinal Cord Injury (SCI) • Partial or complete spinal cord lesion may result in: • Paralysis • Paresis • Sensory loss • Altered autonomic nervous system function • Altered reflex activity Concorde Career College
Spinal Cord Injury (SCI) • Injury often accompanied by: • Fracture of the vertebra, body, laminae, spinous process • Stretched or torn ligaments • Disc herniation • Disk compression • Malalignment of spinal vertebrae Concorde Career College
Designation of Lesion Level • American Spinal Injury Association (ASIA) • International Standards of Neurological Classification of Spinal Cord Injury (ISNCSCI) – standardizes the way in which severity of injury is determined • Neurological Level – most caudal level of spinal cord w/ normal motor & sensory function bilaterally • Motor Level – most caudal level of spinal cord w/ normal motor function bilaterally • Sensory Level – most caudal level of spinal cord w/ normal sensory function bilaterally Concorde Career College
ISNCSCI Scoring • Motor • Most caudal segment with normal motor function (B) • Uses the same scale as MMT • Cannot test one muscle and assume this represents an entire myotome • Sensation • Defined in the same way in terms of sensory function • Usually tested with light touch and pin prick • 0 = absent,1 = impaired, 2 = normal Concorde Career College
ASIA Impairment Scale Concorde Career College
SCI Classification • Tetraplegia/Quadriplegia • Complete paralysis of all 4 extremities & trunk • Upper Motor Lesion • C1 – C8 (Trunk, Limbs) • Paraplegia • Complete paralysis of all or part of trunk & both LEs • Upper Motor Lesion • T 1 – T12, L1 • Lower Motor Lesion • Below L1 Concorde Career College
Clinical Syndromes • Brown-Sequard Syndrome (incomplete) • Hemisection of spinal cord • Usually secondary to penetration wound – GSW, stab • Ipsilateral sensory loss of sensation, reflexes, vibration and position sense (lateral and dorsal columns) • Contralateral sensory loss of pain and temperature sense (spinothalamic tract) • Cauda Equina Injury • Lesion is below L1 vertebra • Peripheral injury (lower motor neuron injury) • Flaccidity, absent reflexes Concorde Career College
Clinical Syndromes • Anterior cord syndrome • Injury site: anterior spinal cord or ant. spinal artery • Usually related to flexion injuries, compression from fracture, dislocation or cervical disc protrusion) • Characterized by loss of motor function (corticospinal tract) & pain and temp (spinothalamic tract) • Central cord syndrome • Injury site: center of the spinal cord • Most commonly occurs because of hyperextension; congenital or degenerative narrowing of spinal canal • Most common with hyperextension of cx region • Posterior cord syndrome • Injury site: posterior spinal cord or posterior spinal artery Concorde Career College
Clinical Syndromes • Posterior cord syndrome • Injury site: posterior spinal cord or posterior spinal artery • Characterized by preserved motor function, sense of pain and temperature and light touch; loss of proprioception and epicritic sensations (ie: 2 point discrimination) below the level of the lesion Sacral Sparing refers to incomplete lesion; clinical signs include perianal sensation and external anal sphincter contraction Concorde Career College
Clinical Manifestations • Spinal Shock • Motor and Sensory Impairments • Autonomic Dysreflexia • Postural hypotension • Impaired temperature control • Respiratory Impairment • Spasticity • Bowel and Bladder dysfunction (Micturition; Crede maneuver) • Sexual Dysfunction Concorde Career College
Acute Medical Care • Stabilize respiratory status • C1 to C4 lesions effect the phrenic nerve & diaphragm • Patient placed on respiratory ventilator • Minimize spinal shock and edema that results from the injury • Steroids • Control of hydration and nutrition to avoid over hydration and further cord necrosis Concorde Career College
Acute Medical Care • Catheterization bladder • Spinal stabilization • Surgery to realign vertebra & spinal cord • Insertion of halo to head & spine • Rigid to semi-rigid cervical collar • Thoracolumbarsacral Orthoses (TLSO) • Immobilize patient in bed • Stryker Frame, air support beds Concorde Career College
TLSO Concorde Career College
Spinal Cord Injury Disorders • Respiratory Impairment • Impairment is directly related to: • Lesion level • Residual respiratory muscle function • Additional trauma at time of injury • Premorbid respiratory status • Will be dependent on artificial ventilation or phrenic nerve stimulation with C1 – C3 injury • Low respiratory endurance (C4 to T12) • Higher level lesions may result in difficulty with coughing Concorde Career College
Spinal Cord Injury Disorders • Complete to partial motor and sensory dysfunction below the level of the lesion • Autonomic Dysreflexia (Hyperreflexia) • Deep Vein Thrombosis • Inactivity & diminished muscle contraction effect circulation • Sympathetic Pain, Phantom Pain • Dyesthesia • Heterotrophic bone formation in soft tissue • Orthostatic Hypotension (aka Postural Hypotension) • ↓ in BP when assuming an erect or vertical position • Caused by loss of sympathetic vasoconstriction and lack of muscle tone • Example: supine to sitting, sit to stand Concorde Career College
Spinal Cord Injury Disorders • Pressure Sores/Decubitis Ulcer • 2 ˚↓ sensation, difficulty w/ positional changes • Motor Impairment • Spasticity • Varies in range, mild to severe • Influence by internal and external stimuli • Can be managed via drug therapy, injections, surgery • Flaccidity • Muscle weakness • Muscle atrophy Concorde Career College
Spinal Cord Injury Disorders • Bladder and Bowel Dysfunction • UTIs are a common early complication • Lesions above conus medullaris typically develop a reflexive/spastic bladder & bowel (automatic bladder & bowel) • Conus Medullaris and Cauda Equina lesions typically develop a nonreflex/flaccid bladder & bowel (autonomic bladder & bowel) • Calcium Absorption (renal calculi) • Osteoporosis Concorde Career College
Spinal Cord Injury Disorders • Contractures • Autonomic Nervous System Disturbances • Loss of thermal regulation • Vasodilation does not occur in response to heat • Vasoconstriction does not occur in response to cold • Absence of sweating • Often associated with compensatory excessive sweating above the level of the lesion- diaphoresis • Flushing, headaches • Sexual Dysfunction Concorde Career College
