Details and patient eligibility

About

The training consists of 6 weeks of functional electrical stimulation leg cycling exercise (FES-LCE) program. The training program comprises of 2 visits per week. Each visit consists of FES-LCE for 45 minutes. Throughout the 6 weeks program, there will be testing/assessment sessions on week 1, week 3 and week 6. The FES will be applied via surface electrodes and the stimulation intensity based on the participant's tolerance level.

Enrollment: 8 patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers
