Promoting finger separation in individuals with insufficient finger separation using pinching exercises with medium-sized blocks.

Brs 3-4

Case Examples

Fingers extension and separation are present, but pinching and other movements are unstable because of insufficient development of thumb opposition and fingers extension.


Encourage fingers extension and separation, build-up pinching (strength) in thumb opposition

Exercise menu and content

Make fist/extend fingers/relax (Limited mode ON or OFF)

  • Repeated hand flexion and extension (pinching and releasing) in opposition in accordance with instructions from equipment.
  • Repetitive pinching and releasing of objects (object = blocks, medium-sized pegs, etc.).


  • Limited mode used in cases of persistent extension difficulties or instability.
  • Adjust the range of movement to suit the object.
  • Difficulty adjusted depending on the item. (opposition build-up, increased extension range)
  • If it is difficult to build up an opposition using only the device, use a thumb support band, or other method.
  • Provide sensory re-education when pinching items.
