Background and Objective: Visual impairments affect all aspects of movement and the development of personal and social skills in the blind of can be affected by appropriate physical activity. Furthermore, moving, as the primary means of physical education, is essential for promoting health in disabled children. The lumbo-pelvic-hip complex (LPHC) is a region of the body that has a massive influence on the structures above and below it.
It seems that core stabilization training can have multiple effects on balance, performance and strength of blind people who lack one of the chains necessary for balance. Therefore, The purpose of this study was to examine the effect of core stability exercises on the balance, strength and function in blind Goalball boy students.
Methods :This study was an interventional semi-experimental one designed with a pre-test/post-test approach. Overall, based on the Gpower software, 30 golbalist blind male students aged 10 to 16 years as a sample size with an effect size of 0.84 and a confidence coefficient of 0.95.were purposefully selected and then randomly divided into two groups of core stability exercise (weight=54.86±2.14 Kg) and control (weight=56.70±4.14 Kg) groups. After obtaining their consent to participate in the training program, The participants of the core stability group performed the exercise protocol 3 sessions per week for 8 weeks. The participants of control group was asked to continue their daily activity and did not perform any exercise during the study. These exercises based on the gradual progress principle, their intensity were gradually increased over the 8 weeks during the study. The basis of the exercises used in the protocol are specific spinal stabilization exercises, abdominal manoeuvring with multidisciplinary muscle contraction and then maintaining the stabilization manoeuvre using dynamic stability obtained in different positions as well as adding dynamic components to it. before and after the intervention, the dynamic balance was measured by a Y test. the flexor and external rotator strength of the hip, the dorsiflexor and evertor strength of the ankle was measured by a SPF hand-held dynamometer and functional Test was measured using TUG test. Data analysis was performed applying paired and independent-sample t-test in SPSS19 software. The significant level was set at 0.05
Results: The results of paired samples t-test showed that The dynamic balance (Pvalue=0.003), significantly increased in the core stability group at the post-test compared to the pre-test.
Also in intra-group comparison, the right flexor and external rotator strength of the hip (Pvalue=0.040 and 0.001 respectively), ankle dorsiflexor strength (Pvalue =0.001), ankle evertor strength (Pvalue = 0.001) and TUG test (p=0.002) significantly were increased in the core stability group .While there was not such a significant change in the control group (p>0.05). In comparison, the results showed that in both the experimental and control groups, at pre-test, there were no significant difference in variables. On the other hand, based on the results of the independent samples t-test, the right flexor and external rotator strength of the hip (Pvalue=0.029 and 0.049 respectively) and TUG test (Pvalue=0.005) significantly increased in the core stability compared to the control group.
Conclusion: According to the results , it seems that core stability exercises induce more effective favourable changes in strength and function. It is possible to use this type of exercise to reduce the potential risks and injuries in this group of people with disabilities.
