Abstract

BACKGROUND AND PURPOSE: To examine whether three-dimensional (3-D) kinematic analysis can detect changes in upper limb tasks (reach and hand-to-mouth) in children with hemiplegia, following upper limb botulinum toxin A injections. METHODS: Ten children with hemiplegic cerebral palsy (7 males, 3 females, aged 9-17 years). Subjects received botulinum toxin A (Botox) injections into elbow forearm muscles combined with 6 weeks of occupational therapy. Participants completed a 3-D kinematic analysis of two upper limb tasks, Melbourne Assessment of Unilateral Upper Limb Function and modified Ashworth scores measured at baseline, 2, 6 and 12 weeks post-injection. RESULTS: Post-injections, elbow flexor muscle tone was reduced for 12 weeks (p < 0.05). Group differences in active range of motion during 3-D analysis tasks could not be demonstrated at any time post-intervention. However, individual analyses found that at 2 weeks post-injection, three subjects had >15 degrees increases in active elbow extension and six subjects showed an increase of >25 degrees in forearm supination during performance of the reach and hand-to-mouth tasks, respectively. CONCLUSIONS: 3-D kinematics can detect changes in active movements during functional tasks following botulinum toxin A injections, suggesting this could be a potential objective outcome measure in a clinical trial.
