Correction of Toe-Walking Gait in Children with Spastic Cerebral Palsy by using Electrical Stimulation Therapy.

Abstract

Toe-walking is a very common gait abnormality seen in children with Cerebral Palsy (CP). The present study aims to improvise the toe-walking gait by applying Electrical Stimulation (ES) therapy of the Tricep Surae (TS) muscles. The study was carried out on sixteen children with spastic CP with unilateral toe-walking gait problem, divided into the intervention group that received both ES therapy along with conventional physiotherapy treatment and the control group that received only conventional physiotherapy treatment. Both groups were treated for 60 (30 + 30) minutes per day, for 5 days a week, up to 12 weeks. The gait data were analyzed for spatiotemporal and parameters influencing the walking capacity. The results showed that those children who received the intervention had a significant increase in gait speed by 17.67 % (p = 0.019) and decrease in stride length by 10.25 % (p = 0.037), resulting in improvement of body balance. There was a significant percentage increase in initial contact (heel strike) of 85.71 % (p = 0.000) and flat foot position (loading response) of 49.2 % (p = 0.005), confirming reduction in toe-walking. There was also an increase in the swing power by 39.8 % (p = 0.028) and ground impact by 19.5 % (p = 0.003) suggesting a change in foot contact pattern. The results indicate that ES therapy on TS muscle along with conventional physiotherapy may correct the toe-walking gait in children with spastic hemiplegic CP.
