Assessment of the Safety and Performance of a Lumbar Belt

Study Overview
=================
Brief Summary
-----------------
Decathlon has developed the Lumbar belt Soft 300 and Mid 500 products which are medical devices designed to reduce pain and improve function during sport practice for athletes with a common subacute or chronic low back pain. The objective of this multicentre study is to collect data on the related clinical complications and clinical outcomes of market-approved Decathlon Lumbar belt range of products to demonstrate safety and performance of these devices in a real-world setting. Outcome data collected from this study will provide the basis for Post-Market Surveillance (PMS) reporting, Clinical Study Report (CSR), Clinical Evaluation Report (CER) on Decathlon lumbar belt Soft 300/ Mid 500 devices and support peer-reviewed publications on products performance and safety.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Orthosis group 1<br>Use of LumbarBelt Soft 300 device during sport practice (for 12 weeks) | Device: LumbarBelt SOFT 300<br>* 15 patients will be included in this group and will used the medical device LumbarBelt SOFT 300 during sport practice (at least 2 sport sessions per week), for 12 weeks.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Functionnal score | Comparison of the Oswestry Disability Index (10-item questionnaire with a global score from 0=best outcome to 100=worst outcome) between the baseline and last follow-up visit in each group (orthosis vs control), for each device model | Change from Baseline functionnal score at 12 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Confidence level (confidence questionnaire related to physical activity) | Gap in the confidence level related to physical activity (scale from 0=worst outcome to 100=best outcome), between the baseline and last follow-up visit in each group (orthosis vs control), for each device model | Change from Baseline confidence level at 12 weeks | 
| Low back pain | Comparison of low back pain, assessed through a Numerical Rating Scale (NRS) ranging from 0=best outcome to 10=worst outcome, between the groups (orthosis vs control), for each device model | Change from Baseline low back pain at 12 weeks | 
| Safety (adverse events) | Comparison of adverse events rates between the groups (orthosis vs control), for each device model | 12 weeks of follow-up |
