When injury, stroke or disease damages the body's moving parts, current treatments often fail to bring back natural movement. A paralyzed eyelid can leave the eye exposed and painful.

What they work on

  1. Measure how segmental activation of the eyelid-closing muscle produces spontaneous, reflexive and forced blinks in people without paralysis, using intramuscular EMG (electrical recordings inside the muscle) and high-definition 3D eyelid tracking.
  2. Build a mechanistic neuromuscular model of the eyelid from paired muscle-activation and eyelid-motion data, to predict where and when a future neuroprosthesis should deliver stimulation.
  3. Repeat the eyelid recordings in people with partial facial paralysis to determine how abnormal muscle activation compromises blink and eyelid closure.
  4. Develop a compliant limb reconstruction (CLR) pipeline that generates joint- and pathology-specific mechanical properties for flexible implants that correct disrupted joint compliance (how tissue bends under load).
  5. Design, fabricate and validate compliant implants for two limb pathologies with unmet clinical needs, gathering data to support early feasibility studies in human patients.

More about the research

A damaged joint can leave a limb alive but unusable. This research combines surgery and mechanical design, an approach the PI calls "anatomics," in which the body and an implanted device are designed together. One project studies how the nervous system drives eyelid motion so that future neuroprostheses (implanted devices that stimulate nerves or muscles) can restore a natural blink. The other designs flexible implants that correct the mechanics of damaged joints.

Why it matters

People with facial paralysis from stroke or other neurological disorders could one day receive neuroprostheses that restore a natural blink, protecting the eye, easing pain and supporting vision and confidence. Patients whose injured or diseased joints leave a limb painful and nonfunctional could gain flexible implants that restore movement and may help avoid unnecessary amputation.
