Clinical Trial Summary

Cerebral palsy (CP) is a major motor dysfunction manifesting early in childhood, with severe consequences to performance in daily functions. CP children are typically unable to voluntarily activate individual muscles, hindering motor coordination and therefore the ability to produce movements as smooth as those seen in control cohorts. Muscles spanning distal joints are more likely affected by CP, resulting in abnormal gait patterns. While commercially available and customised games have been considered for CP rehabilitation in the last decade, they are mainly based on the analysis of movement kinematics and none seems to deal directly with the key source of motor impairment: the skeletal muscle. Surface electromyograms (EMGs), on the other hand, provide clinicians with the possibility of directly assessing and controlling the neural drive or command to muscles. The benefits of surface EMG as a feedback tool for improving posture control and for stroke rehabilitation are well established. The treatment with EMG-based "serious games" is expected to assist CP children in activating the ankle muscles in both paretic and healthy limbs at similar instants within the gait cycle. Given such EMG-oriented rehabilitation applies directly to the muscle, its effect on muscle and therefore gait function is likely to be greater than that achieved with conventional means. If this hypothesis is verified, it will be further expect to observe a smoother gait, that is smoother changes in gait kinematics and morphology of the paretic foot, in CP children treated with EMG-based serious game than otherwise. Primary objective consists in verifying whether Surface electromyography (sEMG)-based games are effective in reducing the degree of muscular hyperactivity in the ankle plantar flexor and thus improve the ankle dorsi flexor function in children with cerebral palsy. The study design is an open, prospective, monocentric, randomized and controlled trial. Participants will be randomly assigned to either the first group or to the second group. For the first group, the design will be: "physical therapy + serious games" during the first month then "physical therapy" during the second month. For second group, the the design will be: "physical therapy" during the first month then "physical therapy + serious games" during the second month.
