Remapping residual coordination for controlling assistive devices and recovering motor functions

The study explores using body movements to control devices for people with motor disabilities. It uses a "Body-Machine Interface" (BoMI) that remaps residual upper body mobility to control a cursor on a screen. The BoMI uses Principal Component Analysis (PCA) to map movements, allowing programming for functional exercises aimed at motor skill recovery. It can select comfortable movements and challenge difficult ones. The interface can be modified to restore symmetry or increase strength and range of motion, providing assistive device control and rehabilitation simultaneously.

• 1
  The BoMI approach restored symmetry between the left and right sides of the body in participants with spinal cord injuries.
• 2
  Participants experienced an increase in mobility and strength in the upper body parts involved in controlling the interface.
• 3
  The study provides a proof of concept that BoMIs can concurrently control assistive devices and help achieve specific rehabilitative goals.
