Volleyball has become one of the world's most popular participatory sports in recent years. There are many dynamic skills and movements needed to play the game. As a result, many acute and overuse injuries to the shoulder may occur. This article addresses the common injuries and rehabilitation recommendations for the shoulder injuries in the volleyball players. The glenohumeral instability, primary or secondary impingement, internal impingement, labral injuries, and suprascapular nerve lesions are common problems in volleyball players. A basic knowledge of the biomechanics and volleyball maneuvers (blocking, serving, and spiking) can help in the development of appropriate trainging and reha- bilitation protocols. Special emphasis must be placed on the knowledge of muscular patterns involved in serving and spiking, because they typically require a strenuous unilateral action of the dominant shoulder. It is therefore impera- tive to include adequate stretching and muscular training programme for the prevention, as well as for therapy, of shoulder pain in volleyball players.

The youth's rural rehabilitation movement started the crusade against illiteracy and poverty with all young educated elites including Whang Jongjin(a student of Yesan Public Agricultural High School) of the village, Shiryang-ri. Deoksan-myon. Yesan-gun. Among others, Patriot Youn(1908-1932) initiated the movement. The main projects of the agricultural extension were the Evening School(1926), Reading Club, the Woljin.Hoe(1929), Puheung.Won(1928), a Mutual Financing Association for Swine Farming, Sweet Potato Cultivation, Cooperative Planting, the Shuam.Sports Club and Consumer's Cooperative Society. The idea in Nongmindokbon (Famer's Text, 1927) is based on liberalism, equality, independence, a pioneer and cooperative spirit or realization of a physiocratical Utopia. Most references about Patriot Youn are concerned with his heroic deed in Shanghai, however the youth in Shinyang-Ri are typical agricultural extension workers or in other words, a forerunner of Saemaul Undong.

Objective: The forward head posture (FHP) is strongly related to the rounded shoulder posture (RSP), which is associated with shoulder pain. Design: Observational cross sectional study design Methods: A total of 37 were enrolled in the study, 22 individuals with FHP(experimental group) and 15 healthy adults(control group). Correlation with differences between groups was analysed through craniovertebral angle (CVA) representing FHP for both groups, neck disability index (NDI) indicating neck pain, disability of the arm, shoulder and hand (DASH) indicating shoulder pain. Results: There was a significant difference in the results of CVA, NDI, and DASH in FHP and healthy adults (p<0.05). Significant correlations were found between DASH and CVA in FHP participants (r = -0.656, p = 0.001). Also, in the regression analysis results of DASH and CVA, the regression model was found to be suitable and the variation in DASH could be explained by 43% (F = 15.118, p = 0.001). Conclusions: Shoulder pain and neck discomfort are potentially related, and an increase in shoulder pain can increase FHP.

As a result of the increased participation in recreational and competitive sports activity, the incidence of chronic lateral instability has risen. Because chronic ankle instability can cause significant comorbidity and increase the social cost, the interest in this issue is growing. Although there are well-documented and effective surgical treatments for managing this condition, conservative treatments are a viable first option in selected patients. Through conservative treatment, surgical treatments can be reduced or delayed without necessarily affecting the overall outcome, but the failure of conservative treatment results in the need for surgical treatment to reduce the long term complications. Appropriate postoperative rehabilitation is essential for adequate functional recovery, even when surgical treatment is required.

It is important to consider lumbar lordotic angle for setup of training program in field of sports and rehabilitaton to prevent unexpected posture deviation and back pain. The purpose of this study was to analyze the biomechanical impact of the level of lumbar lordosis angle during isokinetic exercise through dynamic analysis using a 3-dimensional musculoskeletal model. We made each models for normal lordosis, excessive lordosis, lumbar kyphosis, and hypo-lordosis according to lordotic angle and inputted experimental data as initial values to perform inverse dynamic analysis. Comparing the joint torques, the largest torque of excessive lordosis was 16.6% larger and lumbar kyphosis was 11.7% less than normal lordosis. There existed no significant difference in the compressive intervertebral forces of each lumbar joint (p>0.05), but statistically significant difference in the anterioposterior shear force (p<0.05). For system energy lumbar kyphosis required the least and most energy during flexion and extension respectively. Therefore during the rehabilitation process, more efficient training will be possible by taking into consideration not simply weight and height but biomechanical effects on the skeletal muscle system according to lumbar lordosis angles.

Initial treatment of multidirectional instability of the shoulder would be a thorough rehabilitation program. If rehabilitation fails to resolve a patient's symptoms, the most commonly performed surgical procedure remains the inferior capsular shift. Eleven patients who had disabling multidirectional instability of the shoulder were managed with the inferior capsular shift. All of the procedure were performed by means of an anterior approach and a laterally based capsular shift. All of the patients were the contact athletes. The purpose of our study was to evaluate the efficacy of the inferior capsular shift procedure in the contact athletic patients, to review the loss of external rotation postoperatively and to discuss their return to sports. Mean follow up duration was 14.5 months(range, 12 to 24). Pain was relieved postoperatively in all cases and most patients could get stability except one case of recurrent subluxation. The average loss of external rotation and forward flexion after the operation were Y and 30 at last follow up. By the rating scale from American Shoulder and Elbow Society, overall scores improved from 49 points to 85 points. The results were excellent or good in 9 patients(82%) out of 11 patients. In reference to return to sports, 10 patients(91 %) of 11 patients returned to their sports with 7 patients (64%) returning at the same levels of competitiveness. The inferior capsular shift procedure was considered to be a recommendable method for the management of the multidirectional instability of the shoulder.

The purpose of this study was to analyze sports injuries in athletes with disabilities during the 2015 National Games in Korea. We conducted a survey to assess sport injuries in 171 male athletes with disabilities who participated in this study. The shoulder was most frequently injured, followed by the fingers and low back. Contusions were the most common type of injury, and were usually caused by collisions with teammates or contact with equipment. Injuries often occur during enthusiastic play in both competition and practice sessions. Injured athletes are emergently treated with medicated spray and patch application by the head coach. Warm-up and cool-down exercises are recommended to prevent injury, and physical therapy is effective after an injury occurs. Based on these findings, an injury prevention training program and athletic trainers should be provided for athletes with disabilities to ensure appropriate care and rehabilitation.

Background: Cervical dysfunction is a common pathomechanical marker in individuals with forward head posture (FHP). To overcome the limitations of the isometric chin-tuck (ICT) exercise, dynamic neuromuscular stabilization (DNS), which emphasizes an entire spinal chain exercise, has recently shown promising clinical results. Objects: Purpose of this study was to compare the immediate effects between ICT and DNS techniques. Methods: 43 young subjects (mean age, $24.0{\pm}5.0$ years) were recruited. Group of subjects with FHP were measured under baseline, ICT, and DNS conditions. Outcome measures included sitting height, longus colli (LC) and sternocleidomastoid (SCM) muscle thickness and LC/SCM thickness ratio. One-way repeated measures ANOVA was used to compare the continuous dependent variables among FHP, ICT, and DNS conditions at p<.016. Results: Both ICT and DNS exercise conditions yielded significantly increased LC muscle thickness, LC/SCM thickness ratio and sitting height than did FHP condition (p<.0001, respectively). Sitting height was significantly greater in DNS exercise than in the ICT exercise (p<.0001). Conclusion: The present results demonstrated that sitting height was greater in the DNS exercise than in the ICT exercise, as well as both corrective postural training exercises were effective on LC/SCM muscle balance ratio when compared with the baseline FHP condition. Therefore, it is considered that DNS exercise can be the recommended exercise for people with FHP.

Public sports facilities, which have increased in number due to continued government attention and investment, are used by a large number of residents in the province. However, the safety management in some facilities is limited due to being carried out with reference to safety management standard manuals as a mere formality. The purpose of this study was to analyze the current safety management status of public sports facilities in Gangwon and to seek out a policy direction that can be used safely by provincial residents. To this end. the study made a comprehensive review of central government and Gangwon government policy trends in sports facility safety management in Gangwon along with actual cases, from which it made the following suggestions for policy directions. First, it proposed the designation and operation of specialized institutions using locally established development and municipal companeie,. universities and cooperatives. and the training and fostering of safety managers for sports facilities. Secod, it proposed the establishment of a foundation to promote a sport facility safety culture such as designation of and commendation for excellent facility safety management on the provincial level. holding case presentations on safety and responsiveness. sports safety experience plazas, sports safety classes, and cartoons for public relations. Third, it proposed setting the foundation for a safety management system that takes into account the greater quantity of leisure sports facilities compared to other cities and provinces. Fourth, it proposed the establishment of an institutional basis to establish support ordinance for sports facility safety management that meets the local conditions in Gangwon. Fifth, it proposed safety management measures for sports facilities at the central government level in parallel with a basic plan for sports facility safety management tailored to Gangwon that matches the conditions on the ground in the region.
