“…The results of the present study with regard to increasing the subject's awareness of unnecessary muscle activity levels through biofeedback are consistent with earlier studies as the subjects reduced their muscle activity (Gerard et al, 2002;Hermens and Hutten, 2002;van Dijk and Hermens, 2006). Auditory biofeedback presented to subjects performing a gross-motor task, showed an increase in the relative rest time and a decrease in muscle activity (Voerman et al, 2004).…”

“…auditory (Gerard et al, 2002), visually (Palmerud et al, 1995), and vibratory signal (de Korte et al, 2008;Vollenbroek-Hutten et al, 2006). However, previous studies have not demonstrated one mode being more effective than the other with regard to reducing muscle activity.…”

“…A reduction of unnecessary muscle activity for a given task and conceivably an interruption in the sustained muscle activity can be the result of biofeedback. EMG biofeedback has earlier been used to reduce EMG muscle activity in both m. trapezius and forearm muscles (Gerard et al, 2002;Hermens and Hutten, 2002;Palmerud et al, 1995;Poppen et al, 1988). Finger flexor EMG biofeedback and typing force feedback presented to touch typists, reduced the 90th percentile typing force, finger flexor, and extensor EMG by 10-20% (Gerard et al, 2002).…”

EMG biofeedback from the upper trapezius resulted in a 7-12% reduction in the EMG amplitude in both right and left trapezius during standardised typing tasks in subjects with computer-work related myalgia (Hermens and Hutten, 2002).…”

Purpose To explore and describe therapeutic approaches for the prevention of upper limb (UL) repetitive strain injuries (RSI) amongst computer users in the twenty-first century. Methods A scoping review was conducted using the method described by Arksey and O’Malley, further enhanced by Levac et al. to ensure rigor, validity and reliability during analysis. Key concepts pertaining to the research question have been mapped, following comprehensive searches of relevant electronic databases namely EBSCOHost (Academic Search Premier, CINAHL, eBook Collection, E-Journals, Health Source-Consumer Edition, Health Sources—Nursing/Academic Edition and MEDLINE), PUBMED and Google Scholar. The identified studies have been presented in a descriptive numerical summary to address the research aim. Results From the 577 studies initially identified, 58 studies were eligible for inclusion in the scoping review after abstract and full text screening. Strategies for the prevention of UL RSIs in computer users were categorised into overarching types of intervention as well as the factors which contribute towards sustained implementation of prevention strategies. Using ergonomic equipment was the most prevalent approach during intervention, breaks and rest periods were found to be the less common intervention offered to prevent RSIs. The majority of the studies noted personal worksite adjustments, including adjustments of the chair, back rest, lumbar support, handles or any arm support to the individual as a strategy to prevent UL RSIs. In high income countries the use of ergonomic equipment was the most common type of approach during intervention, in middle income countries stretches were the most common therapeutic intervention strategy and in low-income countries there was an even distribution between a number of different therapeutic interventions aimed at preventing RSIs. Conclusions The review provides an overview of approaches and a comprehensive baseline for identifying further research required to generate prevention approaches. The information within the review may be used to impact company practice, policy and decision making in terms of developing prevention strategies.
