  • Background: Exploratory study to investigate whether co-exposure to physical wrist stressors and chemicals is associated with carpal tunnel syndrome (CTS) in French male farmers and agricultural workers. Methods: Cross-sectional study of 711 men aged 30-65 years and working as either farmers or agricultural workers in 2009-2010 within a cohort covered by the French Agricultural Workers' and Farmers' Mutual Benefit Fund. CTS and exposure to physical wrist stressors and chemicals were assessed using a self-administered questionnaire. Associations between CTS and personal/medical factors, exposure to physical wrist stressors, exposure to chemicals, and co-exposure to physical wrist stressors and chemicals were studied using multivariate logistic regression models. Results: Forty-four men {5.6% [95% confidence interval (CI) 4.0-7.7]} reported that they had suffered from unilateral/bilateral CTS during the last 12 months. CTS was associated with age, current smoking [odds ratio (OR) = 2.1 (1.0-4.5)], and exposure to physical wrist stressors [OR = 2.6 (1.1-5.9)]. An association was found between CTS and co-exposure to physical wrist stressors and chemicals [OR = 3.3 (0.8-14.3), p = 0.044] in comparison with the no-exposure group. Conclusions: This exploratory study shows an association of CTS with exposure to biomechanical wrist stressors in male farmers and agricultural workers and suggests an association of CTS with co-exposure to physical wrist stressors and chemicals. Owing to the limitations of the study, this result must be confirmed by a prospective study with objective assessments of the outcome and exposure before drawing conclusions on the possible synergistic effects of mechanical stressors and chemicals on the impairment of the median nerve.

  • 본 연구의 목적은 손목관절 CT 검사에서 환자 자세를 X-축, Y-축으로 변화시키고 CT 검사장치의 channel 변화에 따른 MTF 평가를 하는 것이다. CT 장치와 손목 팬텀을 이용하여 isocenter를 중심으로 X-축으로 0(일치), 5, 10, 15 cm 이동시켜 검사하고, Z-축은 반시계 방향으로 -20°, -40° 회전하여 검사하였다. 검사는 16, -40, 64 channel을 이용하여 channel 별 차이가 있는지도 확인하고자 하였다. 검사한 영상은 자뼈와 좌우측 노뼈의 MTF 값을 측정하여 비교하였다. isocenter를 중심으로 X-축으로 이동시킨 실험에서 이동 거리가 커질수록 MTF 값은 감소하였고, 이때 MTF 값은 channel과는 무관한 것으로 확인되었다. Z-축에서 반시계 방향으로 -20°, -40° 손목관절을 회전시킨 실험에서 회전정도와 MTF는 무관한 것으로 확인되었다. 또한 channel과도 무관하였다. 결론적으로 손목관절 CT 검사에서 손목은 X-축 방향으로 이동을 최대한 억제시키고, Z-축으로의 회전은 검사 대상자의 환경에 따라 변화하여도 영상의 MTF에는 큰 영향을 주지 않을 것이라 사료된다.

  • 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.

  • 본 연구의 목적은 마우스 사용 시 손목터널증후군을 예방할 수 있는 스마트장갑을 연구하는 것이다. 연구에 앞서 손목의 좌·우 움직임은 미세하므로 게이지율(Gauge Factor)이 크고, 이력현상(Hysteresis)이 적은 인장 직물 센서가 필요하다. 만능재료시험기(UTM)를 통해 4가지의 직물을 분석하여 각각의 게이지율을 계산하고, 이력현상도 가장 적은 직물을 선택하였다. 또한, 3가지 부착방법을 아두이노로 분석하여 센서값 변화(△Sensor Value) 값이 큰 방법을 선택하였다. 선택된 직물과 부착방법으로 제작한 프로토타입을 아두이노를 통해 데이터 패턴을 분석하였다. 첫 번째는 센서 1개(A 센서)로만 파악하는 방법이고, 두 번째로는 센서 2개(A, B 센서)로 파악하는 방법이다. 손목 왼쪽(A 센서), 손목 오른쪽(B 센서) 양쪽에 인장 직물 센서를 부착하고, 손목을 오른쪽으로 꺾을 때 A 센서는 늘어나서 △Sensor Value 값이 커지고, B 센서는 줄어들어서 △Sensor Value가 작아진다. 반면에 손목을 왼쪽으로 꺾을 때는 반대로 패턴이 분석되었다. 본 연구를 통해 손목이 꺾일 시 LED가 켜지는 알고리즘으로 손목터널증후군을 예방하는 스마트장갑을 연구하였고, 본 연구 결과를 기반으로 후속 연구에서는 10명을 대상으로 직접 마우스를 사용하면서 실제 사용 시 문제점을 파악하고 파악된 문제점을 해결하고자 한다.

  • Purpose: The purpose of this study was to develop sleeve-type restraints and to compare the sleeve-type and conventional wrist restraints. Methods: Forty four pairs of intensive care unit (ICU) patients and their families participated in the experiment. The nurses applied sleeve-type restraints to the patients in the experimental group, and wrist restraints to the control group. The trained research assistant measured ROMs, skin temperature, edema, and skin lesions of both upper extremities (UEs) before, 24, 48, and 72 hours after the restraints applied. The emotional response of family was measured 72 hours after the restraints applied. Thirty one ICU nurses evaluated the efficiency of both types of restraints. Results: Compared to the control group, changes of ROMs, edema, and skin abrasions on both U/Es of the experimental group indicated a significant difference in physical side effects. The emotional response scores of the experimental group were significantly lower than those of the control group. The mean efficiency scores for the sleeve-type restraints were significantly higher than those for the wrist restraints. Conclusion: The results indicate that the sleeve-type restraints are better than wrist restraints with respect to physical side effects, emotional responses of family members, and application efficiency.

  • This paper describes a real time reliable monitoring method and analysis system using wrist type oximeter for ubiquitous healthcare service based on IEEE 802.15.4 standard. Photoplethysmograph(PPG) is simple and cost effective technique to measure blood volume change. In order to obtain and monitor physiological body signals continuously, a small size and low power consumption wrist type oximeter is designed for the measurement of oxygen saturation of a patient unobtrusively. The measured data is transferred to a central PC or server computer by using wireless sensor nodes in wireless sensor network for storage and analysis purposes. LabVIEW server program is designed to monitor stress indicator from heart rate variability(HRV) and process the measured PPG to accelerated plethysmograph(APG) by appling second order derivatives in server PC. These experimental results demonstrate that APG can precisely describe the features of an individual's PPG and be used as estimation of vascular elasticity for blood circulation.

  • 고해상도 초음파 테크닉과 작은 탐촉자들이 개발되면서 표층에 위치하는 작은 구조물들에 대한 검사가 가능하게 되었고, 이로 인하여 초음파는 손목 질환의 진단과 치료에 유용한 도구가 되었다. 초음파를 이용할 때에는 이러한 기술적인 부분 뿐만 아니라 해부학적인 구조와 임상 양상을 잘 이해하여 적용하는 것이 중요하다. 손목의 통증 부위에 따른 대표적인 질환들에 대해 초음파의 접근방법 및 유용성을 정리해보고자 하였다.
