Training the non-preferred hand for fine motor control using a computer mouse

This study examined whether alternating between the preferred and non-preferred hands whilst using a computer mouse could be a viable injury prevention strategy within the workplace. Subjects (n = 30) were randomly assigned to either the control or experimental group, and participated in a 3 week training program involving 30 min of daily practice using only the preferred hand (control group) or both hands (experimental group). Control of the mouse by the non-preferred hand improved significantly (experimental group only) following training. The non-preferred hand for experimental group subjects also reached a level of proficiency equivalent to the preferred hand for work-related tasks. As a result, subjects felt more comfortable using their non-preferred hand for mouse work. The results suggest that with only minimal training, alternating between the preferred and non-preferred hands during work may not substantially reduce productivity.
