Overview

The main objective of the study is to compare the efficacy on back-specific activity limitations at 4 months after-randomisation of home-based cycling using connected ergometric bicycles associated with usual care to usual care.

Lumbar spinal stenosis is a prevalent and disabling condition in elderly people. Lumbar spinal stenosis results in back and leg pain when standing and walking (radicular claudication), while symptoms regress in sitting position. The inability to stand or walk significantly impairs functioning and health-related quality of life of elders, and has an important healthcare cost. The 2 main treatment options for lumbar spinal stenosis are conservative or surgical treatments. Previous data suggested that laminectomy may be more effective on pain and function than conservative therapy. However, the benefit-risk balance of surgery should be carefully considered in this population with numerous co-morbidities, and evidence is inconsistent. Therefore, conservative therapy is usually the first line option. Data regarding exercise therapy are scarce. Flexion-based exercises are usually recommended. A pilot study suggested that flexion-based endurance training program, namely cycling, could be an effective and safe method to improve pain, function and health-related quality of life in elderly people with chronic lumbar pain. However, barriers to adhering to the program were detected and might have influenced clinical endpoints. Non-pharmacological interventions in spinal conditions are not 'one-size-fits-all' and measures to enhance adherence have to be applied. The hypothesis is that home-based cycling using connected ergometric bicycles associated with usual care could be more effective than usual care in reducing back-specific activity limitations at 4 months in people with lumbar spinal stenosis.

Outcomes

Primary Outcomes

Change in back-specific activity limitations

Mean change from baseline in mean back-specific activity limitations in the previous month using the self-administered Oswestry Disability Index (ODI) total score (0 no limitations and 100 maximal limitations).

Time frame: 4 months after-randomization

Secondary Outcomes

Change in maximal walking distance

Mean change from baseline in mean maximal walking distance (meters) using an adapted version of the self-paced walking-test

Time frame: 4 months post-randomization

Change in lumbar pain

Mean change from baseline in mean low back pain intensity in the previous 48 hrs on a self-administered 11-point pain numeric rating scale (0 no pain and 100 maximal pain)

Time frame: 4, 6 and 12 months post-randomization

Change in radicular pain

Mean change from baseline in mean radicular pain intensity in the previous 48 hrs on a self-administered 11-point pain numeric rating scale (0 no pain and 100 maximal pain)

Time frame: 4, 6 and 12 months post-randomization

Change in the physical component of health-related quality of life

Mean change from baseline in the mean physical component of health-related quality of life assessed by the physical component score of the self-administered 12-Item Short Form Survey (9.95 worst possible and 70.02 best possible)

Time frame: 4, 6 and 12 months post-randomization

Change in lumbar spinal stenosis-specific activity limitations

Mean change from baseline in mean LSS-specific activity limitations using the physical function subscore of the self-administered Zurich Claudication Questionnaire (1 no limitations and 4 maximal limitations)
