support versus loaded treadmill training in treatment of children with cerebral palsy

Conditions: Cerebral Palsy

Summary: background: children often suffer from disorders that alter their walking functions, such as cerebral palsy. task-oriented training is one of the recent interventions to improve gait in children with cerebral palsy (cp). some studies have shown the effectiveness of partial body weight support treadmill training (pbwstt) for children with cerebral palsy. another study supports the effectiveness of loaded treadmill training (ltt) by placing additional weight on the lower extremity. there is still inconsistency in the results of studies advising which weight support or weight addition is more appropriate to use in improving walking in children with cerebral palsy. objectives: this study aims to investigate the effectiveness of pbwstt in the treatment of children with cp. furthermore, to compare the effectiveness of ltt with pbwstt. methods: two groups of twenty-two children with spastic cerebral palsy will be involved. ages 4 to 10 and gross motor functional classification system (gmfcs) i -iii. pbwstt includes a 45- minute treadmill training session with 30% weight support for group one and ltt by adding 60% weight to lower limb while treadmill training for the second group. spatiotemporal parameters will be measure additional to balance and endurance functions. statistical analysis: independent t test will be used to detect between group differences and paired t test to detect before and after trial differences. significance level less than 0.05 and confidence interval 95%. study design: randomized clinical trial (parallel arm design).

study design: a randomized clinical trial (parallel arm design) will compare the pre- and post-intervention effects of partial body weight support treadmill training and loaded treadmill training. participants: a convenience sampling technique will be used to recruit the children with cerebral palsy aged between 4 and 10 years who had gross motor functional classification system (gmfcs) from i to iii and who could stand and hold. children will be recruited from the children's hospital, taif, saudi arabia. interventions: the pre-and post-intervention effects of partial body weight support treadmill training and loaded treadmill training will be compared. all children will be randomly divided into two groups. both groups will receive 45-minute treadmill training sessions for 8 weeks (3 sessions per week) with a total of 25 sessions. first group: (partial body weight support treadmill training) involve administration of conventional treatment sessions. further, sessions of partial body weight support treadmill training will be given at the rehabilitation center, outpatient clinic. partial body weight support treadmill training involves a motorized treadmill with an attached unweighting system of 30% of each participant's body weight will be decreased. the treatment session lasts for 45 min (3 sessions/ week, for 8 weeks). a gradual decrease in unweight percentage, that keep knee extended during the stance phase. all procedures will be with assistance and under the observation of a well-trained pediatric physical therapist with an adequate experience with treadmill settings. second group: (loaded treadmill training) will receive a loaded treadmill training in addition to the conventional treatment sessions. loaded treadmill training includes a motorized treadmill with an additional load attached to the child's lower extremities. a 60% mass lower limb weight will be added gradually and upon the child's tolerance. these procedures will be introduced under the supervision of a pediatric physical therapist with experience with treadmill settings. furthermore, both groups will get the same conventional therapy that includes a range of motion, neurodevelopmental approach, and impairment-based therapies such as stretching and strengthening exercises for 30 minutes three times per week for 8 weeks.
