Randomized Controlled Trial

Study Protocol 
Background: Burns lead to persistent and detrimental muscle breakdown and weakness and 
poor physical fitness so Rehabilitation     following     burns     is     integral     to     improving     
physical     and     psychological     outcomes. This study was undertaken to evaluate an 
alternative exercise rehabilitation strategy, so the aim of this work involving To explore the 
outcomes of an Xbox Kinect intervention on     muscle     strength, lean     body     mass     (LBM)  
and     cardiopulmonary fitness  in     severe     pediatric     burn.   
Methods:     Forty   burned     children     with burns covering     40–60% of the total     body     
surface     area (TBSA), aged     10–16     years, were randomized     into     the     standard     of     
care     (n=20),   and  Xbox training group   (n=20)     groups.  All     burned     children     received     
12     weeks  of     routine     physical     therapy     program     (RPTP).     In     addition,     the    
Xbox group received Xbox training involving five games for 50min a day, three times a week 
for12 weeks .Outcomes were leg muscle strength was assessed as peak torque using a Biodex 
Isokinetic Dynamometer, Oxygen consumption capacity, measured as peak VO2, was studied 
using a modified Bruce treadmill protocol, and lean body mass was determined using dual-
energy X-ray absorptiometry. Outcomes were measured at baseline and after 12 weeks of 
intervention. 
Conclusion: These ﬁndings suggest that the use of XbK intervention is a valuable, feasible and 
pleasant approach in order to improve muscle     strength,     lean     body     mass     (LBM)  and     
cardiopulmonary fitness  in     severe     pediatric     burn Xbox   Kinect virtual reality could offer 
as a therapeutic and motivational tool when used with children burn.

Statistical Analysis Plan 
Reported data was analyzed using Statistical Package for Social Sciences (SPSS) computer 
program (version 23 windows) (Charles R Flint, New York, USA). Normality test of data using 
Shapiro-Wilk test was used, that reflect the data was normally distributed. There were no 
univariate or multivariate outliers, as assessed by boxplot and Mahalanobis distance (p > 
0.05), respectively; there were linear relationships, as assessed by scatterplot; no 
multicollinearity. There was homogeneity of variances (p > 0.05), as assessed by Levene's test 
of homogeneity of variances. So, parametric analysis was performed. 
Potential differences in baseline demographic between groups were examined using 
independent sample t-tests. 2×2 mixed design MANOVA was used to examine the effect of 

treatment on the measured dependent variables (LBM, trunk, leg, Vo2 and PT) within group 
as the between-subject variable (experimental received ……… and control received ……..), and 
time as the within-subject variable (pre and post treatment). The variable of interest was the 
group-by- time interaction at an a priori alpha level of 0.05 and 95 % confidence interval.
