OBJECTIVE: To investigate the benefits of the focal use of botulinum toxin in spasticity in the forearm seen after incomplete spinal cord injury. DESIGN: A single case study with standardized assessment before and at three-week intervals after injection. INTERVENTION: EMG-guided selective injection of botulinum toxin. SUBJECT: A 23-year-old man, 18 months post injury. MEASURES: Rivermead Motor Assessment; grip strength; Jebsen hand tests; visual analogue scale; Ashworth spasticity scale. RESULTS: Weakness was seen as expected with some functional losses, but the patient made gains in the areas of concern: shaking hands, typing, using the hand to drink. These gains were sustained at 12 weeks. CONCLUSION: Selective use of botulinum toxin to weaken muscles can lead to functional benefit.
