“…The findings regarding inter-individual differences during pointing device use were consistent with those found in the literature, especially for ulnar deviation, although the range of ulnar deviation was less than previously reported (Burgess-Limerick et al, 1999;Karlqvist et al, 1999;Bystrom et al, 2002).…”

“…Mean and maximum angles of ulnar deviation during mouse use were lower than the previously reported 10-30 in the literature (Burgess-Limerick et al, 1999;Karlqvist et al, 1994;Jensen et al, 1998;Karlqvist et al, 1999). Interestingly, both of the studies in which forearm support was an option reported lower ranges of ulnar deviation, supporting the findings of this study, with Woods et al (2002) reporting means of between 20 and 27 radial deviation regardless of desk type and arm support.…”

“…Group mean angles for wrist extension were higher in the current study than those previously reported in the literature (19-26 ) (Jensen et al, 1998;Burgess-Limerick et al, 1999;Karlqvist et al, 1999;Bystrom et al, 2002). However, they were lower than those found by Woods et al (2002) who reported mean wrist extension as 36 when the wrist was supported, 44 when the forearm was supported and 39 without support.…”

“…not within the span of the shoulders (Karlqvist et al, 1996;Aaras et al, 1997;Cook and Kothiyal, 1998). In the distal upper extremity, mouse users are reported to adopt working postures of wrist extension, pronation and ulnar deviation (Karlqvist et al, 1994;Fernstrom and Ericson, 1997;Cook and Kothiyal, 1998;Burgess-Limerick et al, 1999).…”

Supporting the forearm on the work surface during keyboard operation may increase comfort, decrease muscular load of the neck and shoulders, and decrease the time spent in ulnar deviation. Wrist rests are used widely in the workplace and are more commonly being incorporated in keyboard design. The aim of this study was to examine the effect of wrist rest use on wrist posture during forearm support. A laboratory based, experimental study was conducted (subjects n ¼ 15) to examine muscle activity and wrist postures during keyboard and mouse tasks in each of two conditions; wrist rest and no wrist rest. There were no significant differences for right wrist flexion/extension between use of a wrist rest and no wrist rest for keyboard or mouse use. Left wrist extension was significantly higher without a wrist rest than with a wrist rest during keyboard use (df=14; t ¼ 2:95; p ¼ 0:01; d ¼ 0:38). No differences with respect to use of a wrist rest were found for the left or right hand for ulnar deviation for keyboard or mouse use. There were no differences in muscle activity between the test conditions for keyboard use. Relevance to industryWrist rests are used widely in the workplace and are more commonly being incorporated in keyboard design. Use of a wrist rest in conjunction with forearm support when using a conventional desk does not appear to have any impact on wrist posture or muscle activity during keyboard use. r
