Summary

This trial is testing if electrical stimulations to the rectus femoris (a thigh muscle) can help with movement for people who have post-stroke stiff-knee gait.

Who is the study for?
This trial is for adults who were independent before and can walk continuously for 30 minutes. It's specifically aimed at those with post-stroke stiff-knee gait, which means they have trouble bending their knee when walking due to a stroke. Participants should have mild to moderate impairment and be able to give consent.
What is being tested?
The study tests how electrical stimulation of the nerve that controls the thigh muscle affects reflexes in people with stiff knees after a stroke compared to those without this condition. Additionally, it examines if these reflexes are linked to changes in walking patterns.
What are the potential side effects?
While not explicitly stated, potential side effects may include discomfort or skin irritation from the electrical stimulation or brace wear, muscle fatigue from prolonged walking tests, and possible temporary increase in spasticity or stiffness.
