Power Training Combined With Interval Treadmill Training to Improve Walking Activity in Cerebral Palsy (PT³)
In Brief
A clinical study evaluating Power training combined with interval treadmill training and Strength training combined with traditional treadmill training for Cerebral Palsy and 2 related conditions. Completed, enrolled 44 participants across 2 sites.
Detailed Summary
Ambulatory children with cerebral palsy (CP) experience walking limitations which negatively influence their ability to physically participate in day to day life. The investigators propose that impaired muscle power generation is the key limiting factor affecting walking activity and participation. This proposal represents a combined approach where participants undergo resistance training for muscle power generation in combination with locomotor treadmill training that is based on typical pediatric walking and activity patterns rather than adult protocols, which are endurance or time-based. Therefore, the primary objective of this randomized controlled trial is to determine the effect of lower extremity Power Training combined with interval Treadmill Training (PT³) on functional walking capacity and community-based activity and participation in children with CP. We hypothesize that remediating the most pronounced muscle performance impairment (i.e., muscle power) with power training combined with a task- specific approach to walking that is developmentally appropriate will have a significant effect on walking capacity and performance.
Study Details
Timeline
Interventions
Training will consist of unilateral and bilateral leg presses, targeting the quadriceps, hip extensors, and plantarflexors according to resistance training guidelines for muscle power training. The interval treadmill training portion will include short-bursts (30 seconds) of high speed walking intervals alternating with 30 seconds of low to moderate speed walking for a total of 30 minutes. Participants will train 3 x per week for 8 weeks. Total duration of each session will be approximately 1 hour.
Training will consist of unilateral and bilateral leg presses, targeting the quadriceps, hip extensors, and plantarflexors following the dosing and resistance training guidelines for muscle strength. Traditional treadmill training will consist of walking at steady-state speeds for 30 minutes. Participants will train 3 x per week for 8 weeks. Total duration of each session will be approximately 1 hour.
