“…There have been a wide range of studies which support the considerable link between upper extremity impairments and socio-demographic factors, such as gender [3,23,24], age [11,25,26], marital status [21,26], level of education, and experience [27]. Scholars have also proved that factors relating to the physical work environments,including working hours [21,28], working posture [25,[28][29][30],shift work [26], rest break [30] as well as vibrations [31] importantly influence the experience of upper extremity disorders. Moreover, lifestyle factors, such as physical exercise [21,25], alcohol use [25,32] and smoking [33][34][35] and psychosocial-related factors including job dissatisfaction [36], job stress [30,37], and time pressure [3] have been confirmed as potential risks for the development of musculoskeletal pains.…”
