Validation of a Horizontally Dynamic Armrest for Joystick Controlled Mobile Equipment

The purpose of this work was to validate an addition a dynamic armrest design (DA) for use during inward–outward and fore–aft joystick manipulation. validated compared stationary (SA) no (NA) using surface electromyography (EMG) questionnaire. DA not successful in reducing muscle activation movements when the SA. Furthermore, portion negated improvements seen with design. Despite lack significant muscular findings, most participants preferred SA or NA. However, unlike armrest, which found successfully reduce multiple muscles involved manipulation, results suggest that horizontally support may be necessary inward outward movements.
