Power Training Combined With Interval Treadmill Training in Cerebral Palsy: An RCT.

Area of Science:

• Neurology
• Pediatrics
• Rehabilitation Medicine

Background:

• Cerebral palsy (CP) significantly impacts motor function, particularly walking capacity.
• Effective interventions are crucial for improving mobility and quality of life in children with CP.

Purpose of the Study:

• To evaluate the efficacy of lower-extremity power training combined with interval treadmill training (PT3) versus traditional strength training (STT) in children with CP.
• To assess the impact of PT3 on walking capacity and performance.

Main Methods:

• A multisite, single-blinded randomized clinical trial involving children (10-17 years) with spastic, bilateral CP.
• Participants received 24 sessions of either PT3 or STT.
• Primary outcomes included normalized self-selected and fast gait speed, and muscle power, assessed at baseline and post-intervention (immediate, 2-month, 6-month).

Main Results:

• The PT3 group showed significantly greater improvement in fast gait speed from baseline to 2-month post compared to the STT group.
• Muscle power significantly increased in the PT3 group immediately post-training compared to STT.
• Stride rate intensity also increased immediately post-PT3, though this effect was not sustained at follow-up.

Conclusions:

• Power training combined with high-intensity interval treadmill training (PT3) is superior to traditional strength training (STT) for improving muscle power and fast gait speed in children with CP.
• PT3 offers a more effective approach for enhancing specific aspects of walking performance in this population.
• While immediate gains were observed, long-term maintenance of all improvements requires further investigation.
