Randomized Controlled Trial Multicenter StudyDoes botulinum toxin type A decrease pain and lessen disability in hemiplegic survivors of stroke with shoulder pain and spasticity?: a randomized, double-blind, placebo-controlled trial.
The aim of this study was to assess the efficacy of botulinum toxin type A injections in reducing pain, impairment, and disability in patients who have had a stroke with shoulder pain and spasticity. ⋯ Although botulinum toxin type A shoulder muscle injections in patients who have had a stroke with spasticity and shoulder pain resulted in improvement in selected disability measures, the observed pain reduction was not greater than that found for placebo.
