Lower extremity manifestations of spasticity in chronic spinal cord injury.
The prevalence of various manifestations of spasticity from questionnaire responses and from clinical examination of chronic spinal cord injured patients is reported. Extensor spasms, flexor withdrawal spasms, and clonus were reported by most subjects. Those with incomplete lesions reported more interference with activities, more pain, and less functional usefulness, than did those with complete lesions. Extensor spasms were reported to interfere more with transfers, whereas flexor withdrawal spasms were reported to be more frequent at night and to interfere more with sleep. Increased muscle tone was observed more often in extensor than in flexor muscles. Those with incomplete lesions had more hypertonus and more limited passive joint movements than did those with complete lesions. Flexor withdrawal reactions and extensor spasms were also more pronounced in those with incomplete lesions, particularly those with Frankel grade C lesions.
