Outcome Measures

Primary Outcomes (1)

  • 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).

    4 months after-randomization

Secondary Outcomes (7)

  • Change in maximal walking distance

    4 months post-randomization

  • Change in lumbar pain

    4, 6 and 12 months post-randomization

  • Change in radicular pain

    4, 6 and 12 months post-randomization

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

    4, 6 and 12 months post-randomization

  • Change in lumbar spinal stenosis-specific activity limitations

    4, 6 and 12 months post-randomization

  • +2 more secondary outcomes

Other: usual care

Interventions

Usual care (i.e. standardized prescription of 6 sessions of outpatient physiotherapy), and * 1 supervised session of cycling aimed at explaining how to use the connected ergometric bicycle and at designing a personalized home-based cycling program * a 12-month home-based cycling program using connected ergometric bicycles which intensity and dose are self-determined * 3 phone or email contacts with a care provider to deliver positive feedbacks and encouragements

Home-based cycling program associated to usual care

A prescription of 6 sessions of outpatient physiotherapy
