This study is exploring how different types of visual feedback in a virtual reality (VR) environment can affect hand movement in people who have had a stroke. You would perform hand movements while wearing a head-mounted VR display. The study will test two interventions: "Visual ROM augmentation," where your finger joint movement appears amplified in VR, and "Visual ROM reduction," where it appears reduced. Researchers will measure your joint range of motion (ROM) to see how these visual changes impact your hand movements. The study is looking for 15 people aged 20-70 who have experienced a stroke at least six months ago, with some remaining weakness on one side of their body (hemiparesis) and a specific score on a hand function test (Fugl-Meyer Upper Extremity Section 31-55). It is also recruiting 15 healthy control subjects. People with severe medical illness, hand/arm pain, or complete loss of finger control cannot participate. The current recruitment status is unclear.

Study design

This is an interventional study with 30 planned participants (15 stroke survivors and 15 control subjects). Participants will be randomly assigned to two groups to receive the visual feedback interventions in a different order.

What's involved

You would perform hand movements in a virtual reality environment using a head-mounted display. The study measures your joint range of motion (ROM) at the time of the procedure.
