Plyometrics for Strength and Function After Pediatric Burns

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.

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.

Inclusion Criteria:

• Children and adolescents aged 10-18 years at the time of enrolment.
• History of severe burn injury involving ≥30% total body surface area (TBSA), with lower-extremity involvement.
• Between 6 and 12 months post-hospital discharge.
• Ability to understand study instructions and safely perform the prescribed exercise program.

Exclusion Criteria:

• Pre-existing neurological or musculoskeletal disorders that may affect lower-limb function or study outcomes.
• Severe lower-limb joint contracture limiting functional movement.
• Cognitive impairment preventing understanding of instructions or reliable participation.
• Participation in another structured exercise, rehabilitation, or physical therapy program outside the study protocol during the trial period.
