The purpose of this study was to test the inter-rater reliability of an observational instrument, the Mouse-Personal Computer Style instrument (M-PeCS), which assesses the stereotypical postures and movements of the upper body and upper extremity associated with computer mouse use. Two trained raters independently rated the video clips of 10 computer users completing three mouse tasks (pointing, steering, and dragging) for a total of 30 video clips to determine the inter-rater reliability. All but two items on the M-PeCS had good to excellent reliability (ICC=0.75 to 1.00). These results suggest that most items on the M-PeCS can be used to reliably document computer mouse use style between trained raters. Potential applications of this study include identifying and quantifying the exposure to postural risk factors that may contribute to hand and forearm musculoskeletal pain associated with intensive computer mouse use.

Ergonomic Analysis

Two groups of movement retrained computer users with prior computer-related upper extremity musculoskeletal disorders underwent qualitative orthogonal video motion analysis. Ergonomic analysis of subjects' computer use habits suggests that movement retraining may decrease risk factors for work related musculoskeletal disorders and therefore warrants further study.

Background The guitar-playing community is the largest group at risk of developing playing related musculoskeletal disorders. A thorough investigation of the relationships between the various risk factors and players’ report on musculoskeletal pain using objective and accurate means of assessment has yet to be reported. Purpose (a) to explore the correlations between demographic characteristics, anthropometric measurements, playing habits, and personal habits of guitar player and their complaints of musculoskeletal pain, (b) explore the correlations between the upper body kinematics of guitar players during playing the guitar and their complaints of musculoskeletal pain, and (c) compare the upper body kinematics of guitar players during playing the guitar while sitting versus standing. Methods Twenty-five guitar players (27.5±4.6 years old) filled out questionnaires regarding their guitar-playing habits, and the Standardized Nordic Questionnaires for the analysis of musculoskeletal symptoms. Kinematics of their torso and upper limbs were tracked while they played a tune twice, once while sitting and once while standing. Results We found moderate correlations between the number of painful joints in the last year and factors, such as physical comfort while playing, years of playing, and position during playing. During standing, lower back pain severity correlated with the rotation range of the torso, while during sitting, it moderately correlated with the average radial-ulnar deviation of the right wrist. During sitting, we found higher anterior and right tilt of the torso, combined with greater abduction of the right shoulder, higher flexion in the left shoulder and higher radial deviation in the left wrist. Conclusion Our results point to several risk factors, related both to playing habits but also to playing posture, which should be considered by the guitar players in order to prevent playing-related musculoskeletal disorders.

This study aimed to determine the prevalent site of musculoskeletal pain and its associated risk factors among dental clinicians at the Kulliyyah of Dentistry, IIUM. A validated, pilot-tested self-administered questionnaires were distributed to 160 dental clinicians between March and June 2014 using convenience sampling method. Inclusion criteria includes dentist, clinical supervisors or clinical dental students. Dental clinicians whom were diagnosed with musculoskeletal disorders were excluded. Data obtained were recorded and analyzed using statistical package for the social science (SPSS) software version 19. Pearson correlation test was used to determine the association between the risk factors and pain sites. A total of 146 participants completed the questionnaire (91.3% response rate). The sample consist of 40 dentists (27.4%), 36 Year 3 students (24.7%) and 35 participants (24%) respectively from Year 4 and Year 5. There was high prevalence of neck pain (79.5%), back shoulder pain (74.7%) and lower back pain (71.9%) among dental clinicians. Significant correlation was found between physical activities with upper body region pain sites (r = 0.170, p=0.042) and lower body region pain sites (r = 0.221, p=0.008). There was a significant association between repetitive movements and wrist bending with upper and lower body region pain sites (r = 0.320, p = <0.001) (r = 0.278, p =0.001). No correlation between awkward postures with upper and lower body pain sites. This paper will relate to the Islamic teaching on moderation in working and in maintaining healthy lifestyle. The most prevalent site of musculoskeletal pain experienced by dental clinicians was at the neck area and the least was on the left arm. Repetitive movements, wrist bending and physical activities were associated with upper and lower body region pain sites.

The objectives of this research were to: (1) determine the risk factors in the VDT workstation systems associated with the physical symptoms reported by VDT users; and (2) examine the interrelationship among these risk factors. A research model was developed. A survey was then designed and conducted among 88 computer users. Factor analysis and regression analysis methods were used to analyze the data. Different types of physical symptoms experienced by VDT operators are related to different risk factors. Ocular discomfort is significantly related to screen glare. General musculoskeletal and physical symptoms are related to fatigue and awkward work postures. Upper body symptoms are related to awkward work postures. Psychosocial factors significantly interact with other variables, such as demographic variables, and are associated with awkward work postures and psychological stress. Poor workstation designs are associated with awkward work postures which in turn are related to physical symptoms.
