Background: Visual impairments affect all motion aspects of individuals. Movement as the most important tool of physical education is an important factor to improve the health of people with disabilities. The present study aims to investigate the effect of six weeks of core stability training on postural control, risk of falling, and function of blind people. Material and methods: Thirty-two blind males were randomly divided into two groups: the experimental and the control one. In order to evaluate the postural control, the Berg balance scale, the modified stork stand balance test, and the tandem walking test were used. To evaluate the risk of falling and function, the Timed Get up & Go and Tinetti tests were employed, respectively. Data were analysed via MANOVA statistical analysis test at the significance level of 0.05. Results: Results showed that, after 6 weeks of core stability training, a significant increase was observed in postural control scores, function, and risk of falling in the experimental group compared to the control group and the pre-test condition (P < 0.05). Conclusions: Considering the importance of mobility, especially in people with visual disabilities, the use of core stability training
Context: Range of motion (ROM) and muscular strength are the main factors that affect athletic performance. Self-myofascial release is a flexibility technique, which is used to inhibit overactive muscle fibers. Objective: To investigate the effects of the 8-week self-myofascial release on the isokinetic hamstrings-to-quadriceps strength ratio (H/QRatio) and the ROM of the knee joint among male athletes with the hamstring shortness. Design: A randomized controlled trial. Setting: Research laboratory. Participants: Twenty-four college-aged male athletes with hamstring shortness were selected for this study and were randomly assigned to a foam rolling group (FOAM, n = 12) and a control group (n = 12). Interventions: Participants in the FOAM group performed supervised self-myofascial release program 3 times per week for 8 weeks. The control group received no intervention. Methods: Data were analyzed via 2-way repeated-measure analysis of variance at the significance level of .05. Main Outcome Measures: ROM and the H/QRatio at the velocities of 60°/s, 120°/s, and 180°/s were measured by an isokinetic dynamometer. Results: The results of 2-way repeated-measure analysis of variance demonstrated that hamstring ROM increased in FOAM group (P = .001). No significant changes were found in H/QRatio after self-myofascial release for FOAM group (P ≥ .05). Conclusions: When compared with other methods of stretching, self-myofascial release with foam rolling may be beneficial in increasing ROM without decreasing H/QRatio in people with the hamstring shortness.
Purpose: Kinesio-Taping (KT) is a new therapeutic approach for Shoulder Impingement Syndrome (SIS), which is common in swimmers. This study was performed to investigate the short- and long-term effects of KT on shoulder pain and functional stability in swimmers with SIS. Methods: In this quasi-experimental study (randomized control trial), 28 swimmers with SIS were randomly allocated to the taping and control group. We used the Davis test and Upper Quarter Y-Balance Test (UQYBT) to assess the functional stability of the shoulder girdle and also the Visual Analog Scale (VAS) to assess pain. The data were gathered in three time points: pre-test, 20 minutes, and 72 hours after the procedure. For statistical analysis, we used repeated-measures analyses of variance with a significance level of α<0.05. The analyses were done in SPSS. Results: The results showed that the taping group had a significantly improved in Davis test and UQYBT in the follow-up and the post-test and also significantly improved in VAS in the post-test compared to the control group. Also, the mean scores of pain, UQYBT, and Davis tests in the follow-up were significantly improved. The mean scores of the UQYBT and Davis test in the post-test were significantly better than those in the pre-test in the taping group (P=0.001). However, there was no significant difference between any of the time points in the control group (P<0.05). Conclusion: Given the results, KT can provide a basis for reducing pain and improving the functional stability of the shoulder girdle of swimmers with SIS. KT can be used as a complementary treatment technique in people with shoulder impingement syndrome and prevent possible injuries in the area.
