fes has been found to be useful for treating the symptoms of cerebral palsy. a recent randomised controlled trial (n=32) found significant orthotic and training effects for children with unilateral spastic cerebral palsy. improvements were found in gastrocnemius spasticity, community mobility and balance skills. a recent comprehensive literature review of the area of using electrical stimulation and fes to treat children with disabilities mostly included studies on children with cerebral palsy. the reviewers summarised the evidence as the treatment having the potential to improve a number of different areas including muscle mass and strength, spasticity, passive range of motion, upper extremity function, walking speed, positioning of the foot and ankle kinematics. the review further concludes that adverse events were rare and the technology is safe and well tolerated by this population.
