Brief Summary

Cerebral Palsy (CP) is considered a neurological disorder caused by a non-progressive brain injury or malformation that occurs while the child's brain is under development. CP primarily affects body movement and muscle coordination. Robot assisted gait training (RAGT) is considered to be a promising approach for improving gait related gross motor function of children and youth with CP.

There is weak and inconsistent evidence regarding the use of RAGT for children with gait disorders. Further research is required with increased numbers and with relevant outcome measures to both confirm the effectiveness and clarify training schedules.

The aim of this research project is to investigate the effectiveness of robot assisted gait training on improvements of functional gait parameters in children with cerebral palsy.

Detailed Description

Cerebral Palsy (CP) is a disorder of posture and movement due to a defect in the immature brain. There is evidence that locomotor therapy for regaining walking capacity using the principle of enhancing neuroplasticity by task-specific training is effective in the rehabilitation process of patients with central gait disorders. The use of a robotic device assists in achieving and maintaining physiological walking pattern for extended periods of therapy. The use of robotic devices as an alternative treatment to improve the gait function in patients with CP has increased.

This is a prospective, randomized comparative trial (RCT). This study is designed to compare the effectiveness of conventional physical therapy (CPt) and robot assisted gait training (RAGT) on gait related motor skills of children with cerebral palsy.

Children aged 5 to 18 years with GMFCS Level 2-4, bilateral or unilateral spastic CP are accepted into this study. Participants are randomly assigned to receive CPt or RAGT + CPt.

All two intervention groups will receive 2-3 sessions of CPt per week over 6-8 weeks. CPt sessions are individually customized to the needs of the child.

The participants of RAGT + CPt group also receive 15 sessions of RAGT (2-3 times per week with a maximum of 45 minute each).

Arm && Interventions

Group	Intervention	Description
Robotic assisted gait training (RAGT) + conventional physiotherapy (CPt) group	Conventional physiotherapy	This group will receive 15 sessions of robot-assisted gait training (two or three times per week with a maximum of 45 minutes each) and conventional physiotherapy, which is individually customized to the needs of the child and usually consists of 2-3 sessions of physiotherapy per week.
Conventional physiotherapy (CPt) group	Conventional physiotherapy	This group will receive conventional physiotherapy, which is individually customized to the needs of the child and usually consists of 2-3 sessions of physiotherapy per week.
Robotic assisted gait training (RAGT) + conventional physiotherapy (CPt) group	Robot assisted gait training	This group will receive 15 sessions of robot-assisted gait training (two or three times per week with a maximum of 45 minutes each) and conventional physiotherapy, which is individually customized to the needs of the child and usually consists of 2-3 sessions of physiotherapy per week.

Primary Outcome Measures

Name	Time	Method
Change in GMFM-88 D Item	baseline, 8 weeks, 14 weeks and 20 weeks	The Gross Motor Function Measure (GMFM) is an assessment tool designed and evaluated to measure changes in gross motor function over time or with intervention in children with cerebral palsy. GMFM-88 is a measure developed to evaluate the gross motor function changes in CP children. It has five components: lying and rolling, sitting, kneeling and crawling, standing, and walking. D dimension is for Standing abilities. The score of each dimension is expressed as a percentage of the maximum score.; There is a scoring system with each item scored as 0, 1, 2, 3, or "not tested". A scoring key of 0 - does not initiate, 1 - initiates, 2 - partially completes, and 3 - completed, is used.; It takes between 20-25 minutes to be completed.
Change in GMFM-88 E Item	baseline, 8 weeks, 14 weeks and 20 weeks	The Gross Motor Function Measure (GMFM) is an assessment tool designed and evaluated to measure changes in gross motor function over time or with intervention in children with cerebral palsy. GMFM-88 is a measure developed to evaluate the gross motor function changes in CP children. It has five components: lying and rolling, sitting, kneeling and crawling, standing, and walking. E dimension is for Walking, Running \& Jumping abilities. The score of each dimension is expressed as a percentage of the maximum score.; There is a scoring system with each item scored as 0, 1, 2, 3, or "not tested". A scoring key of 0 - does not initiate, 1 - initiates, 2 - partially completes, and 3 - completed, is used.; It takes between 20-25 minutes to be completed.

Secondary Outcome Measures

Name	Time	Method
Change in Pediatric Quality of Life Inventory (PedsQL) 3.0 Cerebral Palsy Module (Parent Form)	baseline, 8 weeks, 14 weeks and 20 weeks	The PedsQL 3.0 CP module is questionnaire designed to assess the quality of life in children with cerebral palsy. The 35-item PedsQL 3.0 CP Module encompasses seven scales: (1) Daily Activities (9 items); (2) School Activities (4items); (3) Movement and Balance (5 items); (4) Pain andHurt (4 items); (5) Fatigue (4 items); (6) Eating Activities (5items); and (7) Speech and Communication (4 items). A 5-point response scale is utilized across child self-report for ages 8 to 18 years and parent proxy-report (0=never a problem; 1=almost never a problem;2=sometimes a problem; 3=often a problem; 4=almostalways a problem).
Change in 6 Minute Walk Test	baseline, 8 weeks, 14 weeks and 20 weeks	The 6 Minute Walk Test is a sub-maximal exercise test used to assess aerobic capacity and endurance. The distance covered over a time of 6 minutes is used as the outcome by which to compare changes in performance capacity.
Change in 10 Meter Walk Test	baseline, 8 weeks, 14 weeks and 20 weeks	The 10 Metre Walk Test is a performance measure used to assess walking speed in meters per second over a short distance.
Change in Modified Ashworth Scale	baseline, 8 weeks, 14 weeks and 20 weeks	The modified Ashworth scale is the most universally accepted clinical tool used to measure the increase of muscle tone.
Change in Goal Attainment Scale (GAS)	baseline, 8 weeks, 14 weeks and 20 weeks	The GAS methodology is congruent with the client-centered occupational therapy philosophy because GAS provides a means to identify intervention outcomes that are specifically relevant to individuals and their families.
