简要总结
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.
详细描述
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.

研究组 & 干预措施
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.

Standard Exercise Group
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.

结局指标
主要结局
Lower-Limb Muscle Strength
时间窗: pre-intervention (Week 0)
Quadriceps and hamstring strength will be assessed using an isokinetic dynamometer. After standardized positioning, stabilization, warm-up, and familiarization, participants will perform five maximal reciprocal knee extension/flexion repetitions. The highest peak torque value (Nm) for hamstrings and quadriceps will be recorded.
