Abstract
Reachers are common assistive devices prescribed to help individuals carry out their day-to day activities. The purpose of this study was to examine the effect of muscle activity in the arm and forearm when using two commercially available reachers of different lengths. Fifteen women between the ages of 23 and 25 performed a reaching activity that simulated moving a soup can from a cupboard to a counter. Surface electromyography was used to measure the muscle activity in the arm and forearm and to gain an understanding of the relative contributions of different muscles when using the short-handled reach in comparison to the long-handled reacher. The results showed no significant differences between the short and the long reacher conditions for any of the muscles investigated. PRACTICE IMPLICATIONS. The length of a reacher does not necessarily affect the amount of muscle strength required in some muscles and may not be a major factor in the therapist's choice of reacher length.
