Efficacy of New Protocols in the Treatment of Upper Limb Dysfunctions in Patients With Cerebral Palsy

SES group received the SES training in addition to traditional rehabilitation. Each SES session involved electrical stimulation followed by UE training in addition to home program.The novel SES programs were conducted three times per week, for 12 weeks. Each SES session involved electrical stimulation followed by UE training in addition to home program. The SES was applied to the forearm and whole hand with mesh glove for 20-30 minutes and arm with wrap for 20-30 minutes. The pulse width was set to 300 us for all stimulation levels. The frequency was set to 40-50 Hz.

The UE VCT programs were conducted three times per week, for 12 weeks. Each UE VCT session involved upper limb cycling training followed by UE training in addition to home program. The cycling program consisted of a warm-up exercise, twenty repetitions of hand push-up movements in the sitting position, UE cycling, and a cool-down exercise. The warm-up and cool-down exercises involved stretching and relaxing the head, neck, and the upper and lower body.

VRCIT group received the VRCIT training in addition to traditional rehabilitation, conducted three times per week, for 12 weeks. Each VRCIT session involved practice of functional tasks with the more affected UE followed by virtual-reality based eye-hand coordination tasks with the more affected UE for, in addition to home program, and restraint of the less affected UE for 3.5 to 4 hours per day. The functional training of the more affected UE focused on massive practice of functional activities using the more affected arm, with the principles of shaping and repetitive task practice applied during training.

The absence of muscle contractions was controlled by the investigator the sham stimulation was carried out identically, but the stimulation amplitude was set to 0 milliampere(mA). Subjects were not informed about the stimulation level and were instructed to distract attention from the stimulation.
