Objective: The objective was to assess the outcome of selective motor fasciculotomy in relieving upper limb harmful resistant spasticity and thereby to improve motor functions in persons with cerebral palsy. Materials and Methods: Twenty people having cerebral palsy (12 females and 8 males) with age ranging from 5 to 35 (mean 12.85) years with upper limb resistant spasticity due to spastic hemiplegia (n=7), triplegia (n=6), and quadriplegia (n=7) were assessed using Modified Ashworth Scale, Selective Voluntary Control Grade, Wee FIM Scale and hand function evaluation. Selective motor fasciculotomy was performed on the musculocutaneous nerve (n=13) for elbow flexors spasticity, median nerve (n=24) for pronators and radial wrist flexors spasticity and ulnar nerve (n=3) for ulnar wrist flexors spasticity. Pre- and post-op therapeutic exercises were performed. Results: Statistical analysis using the Wilcoxon Signed Ranks test showed significant reduction in spasticity and improvement in selective voluntary control, hand functions (grasp to hold a 2 inch rod), and Wee FIM (self-care domain in particular). There was no recurrence in spasticity and complications following surgery. Conclusions: The selective motor fasciculotomy of musculocutaneous, median, and ulnar nerves significantly reduces spasticity in the affected muscle groups and thereby improves the self-care (motor) functions in selected people with cerebral palsy who have harmful resistant spasticity without any organic shortening of the muscles. The procedure is safe and the spasticity does not recur.
