Open your clenched hand and start your training.

Its special biomechanical design enables fingers to grasp various objects in a natural grip pattern. During operation, users will actively flex their fingers to grasp the target object. When the fingers relax, an elastic system assists in opening the hand to release the object.

  • It uses elasticity to help open clenched hands and perform grasping training, providing accurate motion feedback to the hand.
  • With its highly personalized design, the assistive force of each of the five fingers can be adjusted continuously, and the wrist joint can also be adjusted in angle.
  • Adjustments can be made according to the user's muscle tone.
