Abstract
Background & Objectives: Blind people have difficulty in the interplay between sensory inputs and motor responses to maintain balance and control posture. They also experience several risk factors associated with falls, such as impaired sensation, reflexes, and coordination. Visual impairments affect all aspects of movement, and the development of personal and social skills in blind people 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. Core stabilization training seems to affect the balance, performance, and strength of blind people who lack one of the chains necessary for balance. Therefore, this study examines the effect of core stability exercises on the balance, strength, and function of blind goalball boy students.
Methods: This quasi–experimental study employed a pretest–posttest design. Overall, based on the G*Power software, 30 goalbalist 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. Then, they were randomly divided into core stability exercises (weight: 54.86±2.14 kg) and control (weight: 56.70±4.14 kg). 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 control group participants were asked to continue their daily activity and did not perform any exercise during the study. These exercises were based on the gradual progress principle, and their intensity was gradually increased over the 8 weeks of the study. The basis of the exercises used in the protocol is specific spinal stabilization exercises, abdominal maneuvering with multidisciplinary muscle contraction, maintaining the stabilization maneuver using dynamic stability obtained in different positions, and adding dynamic components. A Y test measured the dynamic balance before and after the intervention. The flexor and external rotator strength of the hip, the dorsiflexor, and the evertor strength of the ankle were measured by an SPF hand–held dynamometer, and functional ability was measured using the 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: Regarding the intragroup comparison, dynamic balance (p=0.003), right hip flexion strength (p=0.040), hip external rotator strength (p<0.001), ankle dorsiflexion strength (p<0.001), ankle evertor strength (p<0.001), and TUG test (p=0.002) of the core stability training group showed significant improvement in the posttest compared to the pretest. Regarding the intergroup comparison, there was a significant increase in the flexion strength (p=0.029), right hip external rotator strength (p=0.049), and TUG test (p=0.005) variables of the core stability training group compared to the control group. However, there was no significant difference for other components of core strength, core endurance, and balance variables (p>0.05).
Conclusion: According to the results, core stability exercises seem to induce more effective favorable 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.
