About this study

Official title: 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.

Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Plyometric TrainingOther

    Also called Plyo-Tr group

    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.

  • Standard Exercise ProgramOther

    Also called Control Intervention

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Lower-Limb Muscle Strength

    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.

    Measured: pre-intervention (Week 0)

  2. Lower-Limb Muscle Strength

    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.

    Measured: immediately post-intervention (Week 12)

Secondary outcomes (16)
  1. Vertical Jump Height

    Vertical Jump Test: Lower-limb explosive power will be assessed using a vertical jump performed on a force plate. Participants will jump maximally with hands on hips to minimize arm contribution, completing three trials with 60 seconds of rest between trials. The highest jump height will be recorded in centimeters.

    Measured: pre-intervention (Week 0)

  2. Vertical Jump Height

    Vertical Jump Test: Lower-limb explosive power will be assessed using a vertical jump performed on a force plate. Participants will jump maximally with hands on hips to minimize arm contribution, completing three trials with 60 seconds of rest between trials. The highest jump height will be recorded in centimeters.

    Measured: immediately post-intervention (Week 12)

  3. Broad Jump Distance

    Horizontal lower-limb power and dynamic leg strength will be assessed using the broad jump test. Participants will perform three maximal two-footed forward jumps from a marked starting line, with 60 seconds of rest between trials. The longest distance, measured from the starting line to the rearmost landing point, will be recorded in centimeters.

    Measured: pre-intervention (Week 0)

  4. Broad Jump Distance

    Horizontal lower-limb power and dynamic leg strength will be assessed using the broad jump test. Participants will perform three maximal two-footed forward jumps from a marked starting line, with 60 seconds of rest between trials. The longest distance, measured from the starting line to the rearmost landing point, will be recorded in centimeters.

    Measured: immediately post-intervention (Week 12)

  5. Reactive Strength Index

    Reactive strength will be assessed using a drop jump from a 30-cm box onto a force plate. Three trials will be performed with 60 seconds of rest, and the highest reactive strength index value, calculated as jump height divided by ground contact time, will be recorded.

    Measured: pre-intervention (Week 0)

  6. Reactive Strength Index

    Reactive strength will be assessed using a drop jump from a 30-cm box onto a force plate. Three trials will be performed with 60 seconds of rest, and the highest reactive strength index value, calculated as jump height divided by ground contact time, will be recorded.

    Measured: immediately post-intervention (Week 12)

  7. Lower Extremity Functional Scale Score

    Lower-limb functional ability will be assessed using the 20-item Lower Extremity Functional Scale, which evaluates perceived difficulty in activities such as walking, running, stair climbing, and squatting. Each item is scored from 0 to 4, with a total score ranging from 0 to 80. Higher scores indicate better functional capacity.

    Measured: pre-intervention (Week 0)

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Lower-Limb Muscle Strength (time frame: pre-intervention (Week 0)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07590557, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 May 2026.
