視障按摩人員肌肉骨骼不適之人因調查研究

An Ergonomic Survey of Musculoskeletal Discomfort for the Visually Impaired Masseurs

按摩人員作業時，經常會有較大的體力付出，因而增加職業性肌肉骨骼傷病的盛行率。本研究利用北歐肌肉骨骼問卷（NMQ, Nordic Musculoskeletal Questionnaire）及人因基準線風險認定檢核表（BRIEF, Baseline Risk Identification of Ergonomic Factors），針對視障按摩人員進行調查，以瞭解其肌肉骨骼危害情況。問卷受訪視障按摩人員200位，BRIEF受檢核人員12位。問卷結果發現，89.5%的受訪者表示在過去12個月中有一處以上身體部位的肌肉骨骼不適症狀，其中以下背（65.9%）、肩膀（64.8%）、及手或手腕（62.6%）為反映不適的受訪者人數最多的前三位。BRIEF結果顯示，於按摩床進行全身按摩時，手/手腕及背部的高風險人數百分比均為100.0%，於按摩椅進行上半身按摩時，手/手腕及背部所佔比例分別為100.0%及83.3%，二項作業中頸部均為33.3%。研究顯示，視障人員的下背、手或手腕及肩頸為按摩作業高風險的身體部位，建議應積極進行改善，避免視障按摩人員肌肉骨骼傷害。

The physically demanding nature of massage therapy has revealed an increasing prevalence in work-related musculoskeletal disorders (WMSDs) among masseurs. A survey using Nordic Musculoskeletal Questionnaire was conducted and BRIEF (Baseline Risk Identification of Ergonomic Factors) checklist was executed for the visually impaired masseurs to explore the WMSDs risk factors. Two hundred subjects and twelve subjects were recruited to participate as paid volunteers for questionnaire survey and BRIEF assessment, respectively. The results of the questionnaire showed that 89.5% subjects had musculoskeletal complaints with at least one body part in the past 12 months. Lower back (65.9%), shoulder (64.8%), and hand/wrist (62.6%) obtained the largest musculoskeletal complaint rates. BRIEF results showed that hand/wrist and back had 100.0% of high risk scores for whole body massage and 100.0% and 83.3% for upper body massage, respectively. Neck obtained 33.3% of high risk scores for both whole body and upper body massage. The study results indicated that lower back, hand/wrist, shoulder, and neck were the body parts at high risk for masseurs. Improvement measures should be made to prevent the WMSDs in massage therapy.
