Antispastic therapy with botulinum toxin type A in patients with traumatic spinal cord lesion.
OBJECTIVE
The purpose of this study was to determine the effect of botulinum toxin injections for the treatment of spasticity after traumatic spinal cord injury.


METHODS
9 patients were included in this prospective designed study, with a follow-up of at least 2 years. All patients suffered from a massive spasticity after traumatic spinal cord lesion. Conservative treatment options did not show satisfying results. All patients were injected a maximal dose of 2,000 units of botulinum toxin A in no more than 6 skeletal muscle groups. Clinical control examinations were performed after 2 weeks and after at least 2 years.


RESULTS
6 patients reported a good or very good result. One patient offered increasing difficulty in walking for a short time after injection. 2 patients showed no beneficial effects. One patient experienced a modest temporary general weakness for 3 days. After 2 years, 3 patients showed improved function with persistent reduction of spasticity. In the other cases, the beneficial effect lasted for an average of 9 months.


CONCLUSIONS
Botulinum toxin A injection seems to be an effective complementary therapy option in the treatment of spasticity of paraplegic patients with complete deficit of their motor function (ASIA A and B) and a spastic distribution pattern, effecting only a limited number of muscle groups. Caution has to be recommended for incomplete paretic patients, who are able to walk.
