Plyometrics for Strength and Function After Pediatric Burns

10 maja 2026 zaktualizowane przez: Maged Basha, Qassim University

Rebuilding Capacity With Plyometrics: A Novel and Potent Stimulus for Strength and Power, and Functional Performance in Pediatric Post-Burn Population

Pediatric burn survivors may experience persistent deficits in lower-limb strength, explosive power, and functional performance after hospital discharge. This randomized controlled trial evaluated whether a 12-week supervised plyometric training program improves lower-extremity muscle strength, power, and functional capacity compared with a standard exercise program in children and adolescents with severe burn injuries.

Szczegółowy opis

This two-arm, parallel-group, single-blind randomized controlled trial included 62 pediatric burn survivors aged 10-18 years with severe burns involving ≥30% total body surface area and lower-limb involvement. Participants were recruited 6-12 months after hospital discharge and randomly allocated in a 1:1 ratio to either plyometric training or standard exercise.

Both groups received supervised exercise twice weekly for 12 weeks. The experimental group completed progressive plyometric exercises designed to enhance lower-extremity explosive power and dynamic functional mobility. The control group received standard post-discharge rehabilitation focused on flexibility, aerobic conditioning, mobility, and basic strengthening. Outcomes were assessed at baseline and immediately after the 12-week intervention by blinded assessors.

Interwencja / Leczenie
Eksperymentalny: Plyometric Training Group
Participants received a 12-week supervised plyometric training program, twice weekly, with each session lasting 45 minutes. Sessions included dynamic warm-up, progressive plyometric exercises targeting vertical and horizontal force production, and cool-down.
Inny: Plyometric Training
Participants in the plyometric training group will receive a 12-week supervised program, with each session lasting 45 minutes and designed to improve lower-extremity explosive power and dynamic functional mobility. Sessions will include a 5-minute dynamic warm-up, 35 minutes of progressive plyometric exercises targeting vertical and horizontal force production, and a 5-minute cool-down. Training will be individually supervised with safety measures including shock-absorbing flooring, cushioned footwear, technique monitoring, and standardized rest intervals.

Participants received a 12-week supervised standard exercise program, twice weekly, with each session lasting 45 minutes. Sessions focused on flexibility, aerobic conditioning, mobility, and basic lower-limb strengthening.
Inny: Standard Exercise Program
Participants in the control group will receive a 12-week supervised program, with each session lasting 45 minutes post-discharge burn rehabilitation program focusing on mobility, flexibility, aerobic conditioning, and basic lower-limb strengthening. Sessions will include warm-up, stretching, moderate-intensity aerobic exercise at 50-70% of age-predicted maximum heart rate, strengthening exercises, and cool-down, with progression based on participant tolerance.

Lower-Limb Muscle Strength
Ramy czasowe: pre-intervention (Week 0)
Quadriceps and hamstring strength will be assessed using an isokinetic dynamometer.
