The musculoskeletal and support systems along with biomechanical factors lead to tissue adaptations in the skeletal, musculoskeletal and nervous systems, resulting in changes in movement pattern. The aim of this study was to investigate the effect of tactile feedback along with corrective exercises on the degree of thoracic kyphosis in people with Hyperkyphosis . Twenty patients with postural kyphosis greater than 42 were selected voluntarily and randomly divided into experimental and control groups. In the pre-test and post-test, the degree of kyphosis of both groups was measured using a flexible ruler. In the intervention phase, both groups performed corrective exercises for 8 weeks, 3 sessions per week and each session for 30 to 45 minutes. With this difference, the experimental group received tactile feedback, but the control group did not receive any feedback. The results of 2-factor analysis of variance showed that tactile feedback along with corrective exercises (D = -12%) compared to corrective exercises (D = -8%) led to a reduction in kyphosis in people with Hyperkyphosis (P = 0.018).It seems that tactile feedback with changes in sensory inputs can be an effective complement to corrective exercises to reduce the degree of kyphosis.

Purpose: This research aims to investigate the quadruplet role of modern media (education, informing, making social participation, and culturing) on the development of Zurkhaneh sport. Method: This research is applicable in terms of objectives and is descriptive research in terms of data gathering methods. The statistical society of this research includes the athletes, experts, and activists of sports media in the context of the Zurkhaneh sport. Because the exact number of this society was not clear, the number of 384 persons were selected by random sampling. Its measuring tool was the researcher-made questionnaire that 12 professors and experts approved its content validity and its reliability was calculated using the compound reliability (Dillon – Goldstein) and was about 0.82. In addition, the SPSS software was used to analyze the data and PLS software was used to preset the model. Results: The results show that the “informing” factor had the maximum role in developing the Zurkhaneh sport with the factor loading of about 0.93. The other factor that had many roles in developing the Zurkhaneh sport was the “social participation” with the factor loading of about 0.91. The “education” factor with the factor loading of about 0.90 was in third place and the last factor was the “culturing” with the factor loading of about 0.90. Conclusions: According to the results of this research, it could be stated that modern media have obtained such power in the communication era that could affect public opinion. Therefore, the potentials of the modern media and their infinite capacity can be used by proper and correct operational planning to make great movements in developing various aspects of Zurkhaneh sport inside and outside of the country.
