Study on Mechanical Cost of Walking for Stroke Survivors

This study is looking at a new way to measure how much effort it takes for people with walking difficulties after a stroke to move. It's called "Resisted walking" and involves walking on a treadmill with some resistance. The goal is to understand if this new measurement, called "biomechanical cost of walking," can accurately show how efficient your walking is, similar to how we measure the energy your body uses (metabolic cost of walking). Researchers want to see if this new measure is reliable and can detect changes in walking efficiency. You might be able to join if you are 30-80 years old, had a stroke at least 3 months ago, and have some walking impairment, like walking slower than 1.0 meter per second. The study plans to enroll 18 participants.

Study design
This is an interventional study, meaning participants will receive a specific intervention (resisted walking). It aims to enroll 18 participants.
What's involved
Participants will engage in comfortable speed treadmill walking with resisted forward progression. Measurements will be taken at the 1st and 5th minute of these walking trials.
Compensation
Not stated in the trial record.
Follow-up
Measurements are taken at the 1st and 5th minute of the walking trials. No further follow-up is specified.
