Effect of functional electrical stimulation on postural control in children with hemiplegic cerebral palsy: a randomized controlled trial
Abstract
Abstract Background Children with cerebral palsy have impairments of postural control during static and dynamic activities. Improving postural control is one of the primary objectives of rehabilitation for children with cerebral palsy. Therefore, the objective of this study was to study the effect of functional electric stimulation on postural control in children with hemiplegic cerebral palsy. A randomized controlled study was conducted on 30 children with hemiplegic cerebral palsy (18 boys and 12 girls) between the ages of 8 and 12 years. The children were distributed in two equal groups. The experimental group received functional electrical stimulation (pulse width 300 μs, frequency 33 Hz, 2 h/day, 3 days/week, / 3 consecutive months) in addition to the traditional physical therapy program. While the control group received the traditional physiotherapy program only for the same duration. The outcomes included postural stability indices that were measured at baseline and following 3 months of intervention using the Biodex balance system. Results A significant improvement was found in the postural stability indices of children in both groups, comparing their mean values before and after treatment. Furthermore, the results revealed a greater improvement in the postural stability of the experimental group (P < 0.001). Conclusion Functional electrical stimulation may be a useful tool to enhance the postural stability of children with hemiplegic cerebral palsy.
