Supermarket Checker Motions and Cumulative Trauma Risk

Musculoskeletal complaints, functional capacity, personality and psychosocial factors

“…This result is in agreement with a study on CTS (Roquelaure et al 1997) that showed a decreased risk of CTS when the subject was able to change activity during the day and/or take breaks during at least 15% of the working time. It is also in agreement with work showing a positive relationship between working hours and the existence of wrist-hand MSDs (Harber et al 1993;Ingelgard et al 1996;Margolis and Kraus 1987).…”

Musicians' playing-related musculoskeletal disorders: An examination of risk factors

“…Rather than dealing with a specific risk factor (e.g., gender) for a particular disorder (e.g., tendinitis) in one instrumentalist (e.g., cellists), this study was designed to investigate global risk factors for PRMDs in several different instrumentalists. This approach is consistent with several studies of workrelated musculoskeletal disorders which use aggregate outcomes (e.g., upper-extremity cumulative trauma disorders) [Armstrong and Silverstein, 1987;Feuerstein and Fitzgerald, 1992;Harber et al, 1993;Stock, 1991].…”

Relations between occupational, psychosocial and individual factors and three different categories of back disorder among supermarket workers

“…Most recent studies on grocery store workers and/or checkout operators have focused on carpal tunnel syndrome (Margolis and Kraus 1987;Barnhart and Rosenstock 1987;Morgenstern et al 1991;Harber et al 1993;Panzone et al 1996;Osorio et al 1994). In a storewide study of supermarket employees dating from 1989, Ryan (1989) found that about one-third of the workers reported regular symptoms due to their work, and that the lower back was the most frequently affected body Values are mean ± SD area.…”

“…Carpal tunnel syndrome has been the main subject of study (Margolis and Kraus 1987;Barnhart and Rosenstock 1987;Morgenstern et al 1991;Harber et al 1993;Panzone et al 1996;Osorio et al 1994) among cashiers or grocery store workers, with a reported prevalence of 63% (self-reported symptoms) in the former (Margolis and Kraus 1987) and 23% (clinical diagnosis) in the latter (Osorio et al 1994). Studies from Japan (Nishiyama 1973;Nakeseko 1975;Sakurai and Miwa 1975;Ohara et al 1976) have reported relationships between shoulder and neck symptoms and cash register design and operating techniques.…”
