“…For instance, several studies have shown that placement of the mouse closer to the center line of the operator reduces non-neutral shoulder and wrist postures as well as reducing muscle activity of both the forearm and the shoulder (Sommerich et al, 2002;Dennerlein, 2006;Kumar andKumar, 2008, Harvey, 1997). Other studies have shown that the design of the pointing device has little effect on neck and shoulder posture and muscle activity; however, they do have an effect on forearm muscle activity (Lee, 2005(Lee, , 2008.…”

“…Zhu and Shin [55] in an experimental study among 24 participants found that arms resting at elbow level height produced lowest muscle amplitude activity. In other studies, researchers found muscle activities on the shoulders are lower when the upper arms are positioned at the side of the torso instead of being abducted to the side [56], [57].…”

Multiple literatures show evidences of how office workstation set-ups can influence muscle activities. However, the relationship between the postural adoption due to workstation setup and its effect to muscle oxygen saturation among office workers is unclear. The aim of this study was to investigate trends of muscle oxygen saturation and perceived fatigue ratings between different upper limbs posture variations among representative computer users. A repeated measure experiment was conducted on 15 participants to compare the muscle oxygen saturation and perceived fatigue ratings between four different office work posture variations. Parametric and non-parametric statistical analyses were conducted to analyze significant differences on the dependent parameters. Data analysis showed statistically significant trends (p≤0.050) of lower muscle oxygen saturation in workstation set-ups in which participants were adopting raised shoulder and extended arm positions. In addition, the findings revealed that the perceived fatigue ratings on the shoulder, upper arm and lower arm are the lowest (p≤0.050) in workstation condition where subject can adopt neutral postures. The results highlight the effect of good office workstation setup and work postures to individual muscle oxygen saturation and fatigue levels.

Mouse is one of the most important data entry devices for computers. Undesirable and prolonged postures during work with the computer mouse increase workload, muscle aches and upper extremity musculoskeletal disorders. The present study aimed to evaluate and compare muscle activity during the use of 4 types of mouse, including trackball, trackpad, slanted and standard by Electromyography (EMG). Methods: This experimental study included 15 subjects (7 men and 8 women). The electrical activity of EDC, ECU, ECR, FDS, PQ, and FDL muscles was recorded by EMG while performing a standard task with each mouse. The order of using each mouse was randomized. The obtained results were analyzed by SPSS using the measures of central tendency, Friedman's test, and Independent Samples t-test. Results: The results of assessing the electrical activity level of muscles suggested no statistically significant difference in the recorded EMG between FPL, FDS, and PQ muscles while working with the 4 mice. The electrical activity reduced in EDC, ECR, and FPL muscles with the use of slanted mouse, compared to that of other mice (P<0.05). Discussion: There was no significant differences between the electrical activity of FDS, FPL, and PQ muscles during work with the studied mice. Furthermore, the activity of EDC, ECR, and FPL muscles reduced during work with a slanted mouse, compared to the other types. The habit of using a new mouse can affect the level of muscle activity; thus, the use of a slanted mouse may reduce the incidence of musculoskeletal disorders in the wrist and hand of users in the long run.
