Purpose: The purposes of this study were to survey the extent of pain and discomfort in the musculoskeletal system among visiting housekeepers, above all concerning neck, shoulder, back, wrist, knee, and arm pain and to find possible relations between symptoms and various working conditions. Method: A questionnaire was answered by 174 woman visiting housekeepers living in Kyeonggi-do and Seoul from December 1, 2003 to February 30, 2004. The symptoms of musculoskeletal system were coded by the pain index which illustrates the extent of the symptoms, and analyzed in view of NIOSH guideline and Kim, et. al.'s notion. Result: 1. As to the complaint rate of subjective musculoskeletal symptoms by body region, the figure was the highest for shoulder with 78.2%, followed by back with 66.7%, knee 53.6%, neck 56.3%, wrist 40.2%, and arm 29.2%, respectively. The logistic analysis showed shoulder pain and arm pain have no relation with working and health conditions, and back pain was significantly related to current health condition. In same way, knee pain and wrist pain were found to be mainly related to marital status. 2. Following the NIOSH guideline, the positive rate of subjective musculoskeletal symptoms was found out in following order: shoulder 69.5%, back 59.2%, knee 54%, neck 46%, wrist 32.8%, and arm 25.3%. To investigate the main cause of each disease, the symptoms were classified by pain index, where the value of more than 3 comes to the NIOSH case, and analyzed in term of complaint rate using discrete logistical method : shoulder pain was highly related to the housekeeping time after work, back pain was to current health condition and the heavy weight carrying and neck, wrist, arm pain were commonly related to the ordinary health condition. For knee pain, working speed was a main cause. 3. In view of Kim et. al.'s standard, where the pain index is over 7, the positive rate was showed in order slightly different from previous analyses : shoulder 33.3%. knee 29.9%, back 28.2%, neck 17.2%, wrist 17.2%, and 16.7%. From the logistical analysis, insufficient rest was shown as the main cause of shoulder, back, arm and wrist pain. For neck pain, ordinary health condition was mainly related. In case of knee pain, any apparent relation is not found. Conclusion: According to the logistic regression analysis of musculoskeletal system, there was strong suggestion that the less insufficient physical rest, the more significant disorder complaint. This means that the most musculoskeletal symptom among the visiting housekeepers can be prevented and cured by sufficient physical resting.

Background: Instrument players are exposed to occupational musculoskeletal symptoms due to constant movement and strain to meet the needs of their audience. This can cause dissonance between the player and the instrument and can cause medical problems in the musculoskeletal system such as pain, tendinitis, muscle spasms, and joint hyperextension from overuse of body parts. Objective: The purpose of this study is to comparatively analyze the characteristics and occurrence of musculoskeletal symptoms in professional and student players, and to find out the awareness of the need for health care professionals and special exercise programs for orchestra players. Methods: The subjects were professional orchestral musicians 191 from the three symphony orchestras and music students 209 from the four universities volunteered to participate in this study; 393 subjects (98.25%) completed the questionnaire. symptom prevalence and related factors of playing-related musculoskeletal disorders (PRMDs) were surveyed with a self-administered questionnaire. Standardized Nordic Questionnaire was complemented by adding a visual-among scale and used to diagnose PRMD. Results: High prevalence of musculoskeletal complaints in both professional musicians (85.30%) and student musicians (82.30%). Professional musicians and student musicians also suffered the highest problem in shoulder and neck complaints. Significant differences were found between groups that recognized of necessity for specialized health professionals, professional organizations, and special programs for musicians. Conclusions: Professional musicians and student musicians, like orchestra players, are already exposed to overuse syndrome. However, student musicians lack awareness of the risk of injury compared to orchestra players. We suggest that an appropriate treatment management program for the prevention and early treatment of musculoskeletal system damage should be provided to performers at an early stage.

Purpose: The aim of this study was to develop a mobile app-based musculoskeletal exercise program (AMSEP) for operating room (OR) nurses and evaluate its effects on self-efficacy, the flexibility of the shoulders, lower back, and legs, and musculoskeletal symptoms and fatigue. Methods: The AMSEP was developed based on the information-motivation-behavioral skill model. In total, 48 OR nurses were recruited at a university hospital in Korea and divided into an experimental group (n=24) and a control group (n=24), matched for career experience in the OR. The experimental group participated in the AMSEP, while the control group received a booklet regarding musculoskeletal exercise. Results: The experimental group showed significant increases in self-efficacy (t = -2.77, p = .008) and flexibility of the right shoulder (t = -4.08, p < .001), left shoulder (t = -3.28, p = .002), lower back (t = -3.75, p < .001), and legs (t = -3.96, p < .001) compared to the control group. Musculoskeletal symptoms (t = 2.75, p = .008), and fatigue (Z = -1.98, p = .048) significantly decreased in the experimental group compared to the control group. Conclusion: Our findings indicate that the AMSEP for OR nurses provided information on the prevention of musculoskeletal disorders and methods of exercise, as well as an opportunity for continued exercise performance through self-management. The AMSEP was easily accessible and effective in increasing self-efficacy and flexibility and reducing musculoskeletal symptoms and fatigue.
