description [Purpose] The purpose of this study was to investigate the effectiveness of using a visual feedback-equipped reacher when performing reach-to-grasp tasks. [Subjects and Methods] Seventeen healthy participants with no illnesses or physical disabilities were selected for this study. Activation of the flexor digitorum superficialis and extensor digitorum muscles was assessed using electromyography. Wrist and shoulder momentums were calculated using a three-axis acceleration sensor. Participants were instructed to move 10 ears of plastic corn from right to left using a reacher with and without visual feedback. [Results] Comparison of muscle activity under the two conditions revealed a statistically significant reduction in the activity of the FDS and ED with feedback compared to without. The three-axis accelerometer values showed that wrist momentum decreased significantly with visual feedback compared to without feedback. [Conclusion] The results showed that using the vision-assisted reacher affected upper limb muscle activation and momentum. It is important that assistive devices be developed for effective energy use. Here, providing visual feedback during reacher use was shown to reduce users’ physical fatigue.
