Brief Summary

Cerebral palsy (CP) is the most common childhood motor disability. Weakness, spasticity, and loss of dexterity are the major problems in patients with CP. A novel virtual cycling training (VCT) program for lower limb was to enhance promising muscle strength through promoting the participant compliance and motivation. Sensory electrical stimulation(SES) of whole hand is a novel technique and is commonly used to treatment of spasticity for patients with stroke. Constraint-induced therapy (CIT) is a method for treating developmental disregard and learned non-use of affected limb and improving motor efficiency, functional performance, and activities of daily living for patients with CP.

Detailed Description

This study will proposed 3 novel protocols, including upper extremity (UE) VCT, UE SES, and virtual reality based CIT (VRCIT) in the treatment of upper limb dysfunction in patients with CP. investigators hypothesize that the functioning and health-related quality of life (HRQOL) will improve through biomechanical and physiological changes after different treatment protocols in patients with CP. The biomechanical and physiological changes varied depending on different treatment protocols. This project aims to: 1. the immediate effects of new protocols in these patients through biomechanical, physiological, and clinical measures; 2. the maintaining effects of new protocols in these patients through biomechanical, physiological, and clinical measures;3. the most effective treatment protocol; 3. the biomechanical and physiological mechanism underlying clinical improvement; and 5. the clinical predictors influencing the outcome for new protocols.

This 4-year project will recruit an estimated 92-100 patients with CP. A blind, randomized controlled trial (RCT) study was designed. In the phase I (1st year), investigators will set-up the experimental protocols and perform pilot study. Twenty patients will be randomized into 4 groups: SES, VCT, VRCIT, and shame control groups. In the phase II (2nd -3rd year), 36-40 patients will be randomized into 2 groups: SES and shame control groups. In the phase III (3rd -4th year), 36-40 patients will be randomized into 2 groups:VCT and VRCIT groups. The outcome measures include biomechanical, physiological (muscle tone, muscle strength and endurance, kinematics, bone density, body compositions, metabolism), and clinical assessments, including functioning (motor impairment, movement and participation) and HRQOL, based on the International Classification of Functioning, Disability and Health (ICF) framework. The outcome measures will be administered at before, immediately after 12-week intervention, and 3-month follow-up assessments.

This project is significant for the translational and evidence-based medicine on CP neurorehabilitation. The research will offer valuable biomechanical and physiological biomarker that support motor control models proposed to account for motor problems and new protocol intervention in these patients.

Study Groups

SES group

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.

Group Type: EXPERIMENTAL

SES

Intervention Type: DEVICE

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.

VCT group

VCT group received the VCT training in addition to traditional rehabilitation.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.

Group Type: EXPERIMENTAL

VCT

Intervention Type: DEVICE

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

VRCIT group received the VRCIT training in addition to traditional rehabilitation.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.

VRCIT

Intervention Type: DEVICE

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.

traditional rehabilitation group

Shame control group received the shame SES and traditional rehabilitation programs.

Group Type: ACTIVE_COMPARATOR

traditional rehabilitation program

Intervention Type: DEVICE

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.
