Home-based Cycling for People With Lumbar Spinal Stenosis

This study tests whether an at-home cycling programme (using a stationary ergometric bicycle) can reduce pain and improve walking ability in people with lumbar spinal stenosis (LSS). LSS is a narrowing of the spinal canal in the lower back that pinches nerves and causes pain in the back, buttocks, and legs — particularly when walking. Cycling in a bent-forward position often relieves the pain because it opens up the spinal canal. This trial gives participants a bicycle to use at home and monitors whether this leads to real improvements over time. Spinal stenosis is very common in older adults and significantly limits quality of life. While surgery is an option, many patients prefer non-surgical approaches. This study tests a practical, low-cost home-based option that could be widely accessible if it proves effective. You may be eligible if: - You are 50 years of age or older - A doctor has diagnosed you with lumbar spinal stenosis causing radicular claudication (leg pain when walking) - An MRI or CT scan confirms findings consistent with LSS - You can read and/or speak French You may NOT be eligible if: - You cannot operate a stationary bicycle at home - You already own a stationary bicycle - You have had lumbar spine surgery in the past 12 months - You have cognitive disorders or severe neurological/vascular problems in the legs - You are under legal guardianship or protection Talk to your doctor to see if this trial is right for you.
