Objective: Dynamic neoprene orthosis were assessed in one child with spastic diplegia cerebral palsy using gait analysis.

Materials & Methods: After fitting of the neoprene legging, and initial assessment (with orthosis and without orthosis), there was a period of 6 weeks that child wearing the legging for at least 5 h everyday, and followed which she was re-assessed.

Results: Difference of means of variables in immediate effect of neoperen orthosis showed decrese more of 5 degree in mean of maximum and minimum of knee flexion, decrese of ROM of hip joint and increase of cadence whith orthosis. After 6 weeks wearing orthosis, maximum knee flexion, hip and knee joint ROM decresed and cadence incresed without orthosis and in a cycle of gait.

Conclusion: Dynamic neoprene orthosis appear to provide an improved base of support for functional gains in balance, dynamic stability, general and specific movement control with improved postural and muscle readiness. Both deep sensory and subtle biomechanical factors may account for changes observed. This orthosis developed for a specific child and expected that mechanism of orthosis could be effective in children with type of cerebral palsy.
