Abstract: ObjectiveTo explore the effect of variable hip abduction orthosis on children spastic cerebral palsy.Methods5 children with spastic diplegia cerebral palsy had used variable hip abduction orthosis to correct scissors gait which remained after rehabilitation. The stepping of 5 children was assessed with a gait analysis system base on digital video and image processing which could provide distance rate between knees and hips(K/I) in gait phase. One year Follow up was carried out.ResultsThere was significant difference on K/I before and after using variable hip abduction orthorsis (P<0.05).ConclusionThe variable hip abduction orthorsis can inhibit adductor muscles convulsion, improve model kinesis of scissors gait and stabilize stepping.
