Summary

This study examines the effect of short burst interval treadmill training in ambulatory children with cerebral palsy. Half the sample will receive 20 sessions of training over 4 weeks, while half will receive the training over 10 weeks.

Detailed description

Ambulatory children with cerebral palsy (CP) experience activity limitations which negatively influence their ability to physically participate in day to day life. Therefore, these children are at greater risk for inactivity and functional decline with age. In contrast, typically developing (TD) children engage in short bursts of intense physical activity interspersed with varying intervals of low and moderate intensity within their natural environment. These physical activity patterns are very different from adult patterns Despite these inherent differences, locomotor treadmill training (LTT) protocols designed to improve walking activity in children with CP simulate adult protocols, consisting of continuous low to moderate walking endurance activity. Body weight supported or robot assisted LTT is based on the underlying premise of modifying neural circuitry via spinal pathways. However, this type of training has not been shown to be more effective than other comparable interventions and presents with significant fiscal and logistical barriers to clinical translation. This study will determine the effect of short-burst interval LTT without body weight support on the primary outcomes of walking performance and capacity and the secondary outcomes of day-to-day mobility based participation in children with CP with functional walking limitations. To identify key muscular mechanisms associated with improved walking mobility, the investigators will examine the effects of short-burst interval LTT on quadriceps muscle performance and architecture. Secondarily, the study team will collect preliminary data on two LTT dosing frequencies.
