Burned Subjects
We randomized severely burned children, ages 7 to 18 years, into either a no-exercise group or an exercise group. We only enrolled patients with 40% or more total body surface area (TBSA) burned, as assessed by the “rule of nines” method,16 during excision surgery in the acute phase of injury. Patients were excluded if they had 1 or more of the following: leg amputation, anoxic brain injury, psychologic disorders, quadriplegia, or severe behavior or cognitive disorders. The parent or legal
Results
We enrolled 20 burned children (17 boys, 3 girls) in the study and assessed their 1-year complete longitudinal data. Eleven exercise patients and 9 no-exercise patients were tested at 6 and 9 months postburn, and at 3 months after the supervised and structured exercise program ended. The age range for both groups was 7 to 18 years (13.4±1.8y for the no-exercise group vs 11.8±1.5y for the exercise group, P=.30). There were no differences at 6 months postburn between the groups in age, percentage
Discussion
Our results indicate that there was an increase in muscle strength and LBM in the exercise group after 12 weeks of exercise, whereas in the no-exercise group, both muscle strength and LBM remain relatively unchanged. Three months after the cessation of supervised and structured training, LBM increased significantly only in the exercise group. In contrast, further increases in muscle strength in both groups were not significant. When expressed in absolute values, between-group comparisons of
Conclusions
We report here the benefits of a supervised and structured exercise program relative to a home exercise prescription. In addition, there is a continued improvement in these benefits 3 months after the structured and supervised exercise program is stopped. Further studies are needed to determine what type of exercise maintenance program is optimal in maintaining or further improving LBM and muscle strength in burned children. Such studies should also assess how to best improve nutritional habits

2022, BurnsCitation Excerpt :Because of, most of the children and adolescents had burn evaluate at 1–5 years post burn [44]. These findings suggest that persistence of muscle weakness is reported in children who sustained burn injury ≤ 30% of the total body surface area as compared to normal healthy age-matched subjects after 6 months post-burn [19,43,46]. In the current study, JHFT total scores and most subtests are influenced by age, hand dominant, and time to surgery.

2022, Annals of Physical and Rehabilitation MedicineCitation Excerpt :The expired gases were measured and documented until the child reached volitional exhaustion, and the test was ended. Throughout the graded exercise test, the heart rate was checked continuously, and the child breathed into a face mask (Hans Rudolph Inc., Kansas City, MO, USA) that was attached to a calibrated expired gas analysis system (Zan-680 Ergospiro Ergospirometry System; ZAN Me Bgerate GmbH, Germany) [20]. A Biodex dynamometer (Biodex Medical System, Shirley, NY, USA) was used to assess muscle peak torque.
