Effects of Early Exercise Rehabilitation in Severe Burns
A study testing Exercise in people with Burns, run by Universiteit Antwerpen at 1 site in China.
Trial summary
BACKGROUND: Postburn changes in glucose and protein metabolism are at their peak during the acute phase of severe burns. The resulting metabolic derangements lead to substantial muscle wasting, insulin resistance, which ultimately hampers full recovery and reintegration into society. Read more about this study

About this study
Official title: Pathophysiological Mechanisms and Early Exercise Rehabilitation Counter Measures of Hypermetabolism and Muscle Wasting in Severe Burns.
BACKGROUND:
Postburn changes in glucose and protein metabolism are at their peak during the acute phase of severe burns. The resulting metabolic derangements lead to substantial muscle wasting, insulin resistance, which ultimately hampers full recovery and reintegration into society.

PURPOSE:
This randomized controlled trial was initiated to investigate the effects of exercise-based rehabilitation on muscle wasting, insulin resistance, and quality of life during the acute phase of severe adult burns.
METHODS:
Severly burned adults (40-80%TBSA) will be recruited from one of China's largest burn centres.
Subjects allocated to the intervention group will undergo a 6-12 week long exercise program in addition to standard care rehabilitation. As part of the exercise program, participants will carry out progressive resistance and aerobic training, initiated as soon as medical safety and patient cooperation allow. Exercise type and dosage will be chosen according to patient status in terms of grafts, mobility, and strength.
The control group will receive standard care rehabilitation only, including passive, assisted, active range of motion exercise, functional exercise, and scar treatment.
The results of this translational research will provide insight into the effects and mechanisms of exercise on both a fundamental and clinical spectrum.
Read the detailed description
The added exercise intervention is initiated in line with the following readiness criteria, which were checked prior to each training session:
Criteria:
- Cardiorespiratory stability:
- Mean arterial pressure (MAP) 60 - 110 mmHg
- fraction of inspired oxygen (FiO2) <60%
- partial pressure of oxygen / fraction of inspired oxygen (PaO2/FiO2) >200
- Respiratory rate <40 bpm
- Positive end expiratory pressure (PEEP) <10 cmH2O
- no high inotropic doses (Dopamine >10 mcg/kg/min or Nor/adrenaline <0,1 mcg/kg/min)
- Temp. 36 - 38,5°C
- Richmond Agitation Sedation Scale (RASS) -2 - +2
- Medical Doctor clearance
- Medical research council (MRC) score lower limbs ≥3
Accordingly, the post burn starting time differs per enrolled subject.
Exercises are administered as in-bed exercises or out-of-bed exercises, depending on whether subjects are able and allowed to engage in out-of-bed mobility.
Exercise intensity for resistance training is set at 60% peak force based on a weekly peak force measurement by hand-held dynamometry, or on a 3 RM in case of out of bed exercises. Aerobic exercise intensity is set at 50-75% peak Watts determined by a weekly cycle ergometer or treadmill ramp protocol.

The primary outcome is the main question the study is designed to answer.
Change in quadriceps muscle layer thickness (QMLT)

Analysis: An average of 3 trials will be recorded and analyzed using dedicated software
Measured: Baseline - 12 weeks
Change in rectus femoris cross sectional area (RF-CSA)
Method: B-mode ultrasound on the anterior aspect of the thigh. Technique: minimal pressure. Location: measured at the most proximal distance where the entire muscle belly is still visible on the ultrasound image.
Analysis: An average of 3 trials will be recorded and analyzed using dedicated software.
Measured: Baseline - 12 weeks

Change in insulin resistance
Method: HOMA-2 calculated by fasting plasma glucose and insulin, analysed by Western Blot Chemiluminescence

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 12 Aug 2020.
