Incomplete SCI lesio
Incomplete SCI lesions and their symptoms
Question | Answer |
---|---|
Brown Sequard Syndrome | Hemisection of SC,from stab/gunshot wound. Ipsilateral side: weakness or motor paralysis, loss of proprioception, vibratory sense, 2-pt discrim, decr reflexes, clonus,spasticity. Contralateral side: loss of pain & temp starting few levels below lesion |
Anterior Cord Syndrome | Trauma to anterior cord or anterior spinal artery, flexion injuries on cerv spine. Loss of motor function, loss of pain and temperature below the level of lesion with preservation of light touch, proprioception, and position sense. |
Central Cord Syndrome | Most commonly occurs from hyperextension injuries with minor trauma to cervical region. Results in affecting UE sensation and motor functioning with normal LE functioning; ealry loss of pain and temperature. |
Posterior Cord Syndrome | Very rare with deficits of kinesthesia (2 pt, stereognosis) and proprioception. Ataxic gait with wide BOS may result, motor function is preserved. |
Cauda Equina Syndrome | LMN, Injury below L1 segment that results in damage to sacral and lumbar nerve roots, sensory loss, paralysis, loss of bladder/bowel control can occur. Due to damage to peripheral nerve roots, regeneration may be possible (depending on nerve length.) |
Sacral Sparing | Incomplete lesion in which most centrally located sacral tracts are spared. Perianal sensation, rectal sphincter contraction, cutaneous innervation in the saddle area and active-contraction of the sacrally innervated toe flexors are intact. |
