Abstract
: The aim of this study was to comparison the effect of different core stability training on lower extremities strength among deaf children.
28 deaf students (aged: 8-14 yr) selected and randomly divided into 3 groups: dynamic core stability, static core stability and control. Training continue for 8 weeks and 3 session per each week. The protocol composed of: specific training for spinal column stability, breathing maneuver with multifidus contraction, using dynamic stability in different positions accompany by extremities movements and using swiss ball. Dynamometer device was used to measures the strength of core stabilizer muscles. Dependent t (pre and post comparison in each group) and one way Anova were used to analyze data. Level of significant was 0.05 and statistical calculations were used by SPSS (version 22).
The results of this study show that dynamic and static core stability lead to significant changes in lower extremities strength (P≤0.05, t=2.2, t= 5.7, t= 4.8, t= 2.8, t= 3, t=7.4), but the differences between dynamic and static core stability training and control were not significantly (P≥0.05, f=0.74, f=1.4, f=0.13, f=0.46, f=0.18, f=0.24).
It can be concluded that dynamic and static core stability training can be a benefit method to improve lower extremities strength in deaf children and this finding leads to decreasing risk and probable injuries.
