Chae, John, MD

Research Statement

My research interests are in the areas of post-stroke, upper and lower limb motor and functional restoration, and shoulder pain in hemiplegia. My active projects include the investigation of:

  • Various forms of electrical stimulation for upper limb motor relearning
  • Peroneal nerve stimulation for motor relearning and neuroprosthetic effects
  • Implanted neuroprostheses for upper and lower limb motor restoration
  • Implanted and surface stimulation for reduction of shoulder pain
