| Abstract |1 ) PURPOSE: This study examined the effects of videoconferencing-based telerehabilitation exercise program on the gait, knee function, and quality of life of patients with knee osteoarthritis.METHODS: Forty-eight subjects, who were diagnosed with osteoarthritis of the knee by the radiologic findings, history, and a physical examination, were assigned randomly to a Control group, Experiment group I, and Experiment group Ⅱ. The control group did not perform any exercise program and were educated in understanding and managing the disease of knee osteoarthritis for only one hour.Experimental groups I and Ⅱ were provided with an exercise guidelines book for knee osteoarthritis, and the same exercise 본 논문은 김재윤(2018)의 박사 학위 논문의 요약본임. †Corresponding Author : Mo-Beom Jeong mobeom_j@dauml.net, https://orcid.org/0000-0003-2750-1078 This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. programs were conducted by face-to-face visits and non-face-to-face using telerehabilitation for eight weeks, respectively. To verify the effectiveness of each exercise program, the gait speed, knee disability index, and health related quality of life were measured. All assessments were conducted twice before and after the intervention. RESULTS:The participants who underwent both face-toface and telerehabilitation exercise programs showed an improved gait speed, knee function, and health-related quality of life. In particular, there was no significant difference between the telerehabilitation exercise group and the direct face-to-face exercise group in improving the knee joint function and health related quality of life. CONCLUSION:A these findings the telerehabilitation exercise program for patients with knee osteoarthritis can alternate or supplement the face-to-face exercise program. Therefore, the telerehabilitation exercise program should be used not only as a substitute supplement program but also as an intervention for various diseases.

Purpose: This study compared the effectiveness of sling exercise and McKenzie exercise in patients with acute cervical whiplash associated disorder (WAD) caused by rear-end collision. Methods: Thirty WAD patients were randomly assigned to one of three groups; a sling exercise (SE) group, a McKenzie exercise (McE) group, and a control group. Members of the SE and McE exercised three times a week for four weeks under the researcher's guidance. Three groups performed TENS treatment three times a week for four weeks. Diagnostic radiological equipment was used to measure whiplash injury. Visual analog scale (VAS), neck disability index (NDI), and range of motion (ROM) were used in this study. Results:The three groups showed a significant pre-post treatment difference in measures of VAS and NDI (p < 0.05). The SE group showed a significant pre-post treatment difference in measures of flexion and extension changes compared to the McE and control group (p< 0.05). The SE group also showed significantly greater improvement in the VAS, NDI, and ROM changes than the control group (p< 0.05). Conclusion: These findings indicate that sling exercise is a stronger and more aggressive intervention for treatment of acute WAD patients. Keywords
