One embodiment is a handle supporting a users hand having a large surface for the palm, a trough for the thumb, a protrusion between the thumb and first finger and flared edges to keep the hand from sliding. A support surface is coupled to the stem of a wheelchair joystick gimbal and is biased in forward driving. A second embodiment is a wheelchair joystick movable between forward and reverse positions while maintaining the same orientation relative to the user. A supporting surface is pivotally mounted to a gimbal stem fixed to the wheelchair. The handle pivots to remain in a neutral position with movement of the joystick. A bi-directional spring biases the handle toward a neutral position. A third embodiment comprises a pivot coupled to a gimbal stem and a cup coupled to the user. The assembly is completed by placing the cup over the pivot allowing for movement therebetween.

Powered wheelchair joystick handles

A bilateral upper limb exercise device () for exercising a user's arms comprising a central mounting structure () that is mountable to a fixed surface or structure (), left and right limb supports () for supporting the forearm and/or hand of a respective arm of the user, and a pair of articulated linkage arms () that are pivotably coupled to opposite sides of the central mounting structure () and which are arranged to support a respective limb support () for movement in at least two degrees of freedom in a two-dimensional (2D) movement plane. A mirroring mechanism is also operatively coupled to the articulated linkage arms () such that movement of the opposing limb support relative to a central line of symmetry of the device.
