Conditions
Summary
Low back pain (LBP) represents a common musculoskeletal conditions worlwide, causing substantial disability and economic burden. While traditional semi-rigid lumbar supports are commonly prescribed to alleviate LBP symptoms, their effectiveness remains limited by their static mechanical properties and lack of adaptability to movement patterns. Motorized lumbar support offer a novel approach by allowing the application of controlled decompressive forces while maintaining functional mobility. This experimental study aims to compare the effectiveness between a motorized lumbar support and a standard semi-rigid support in adults with non-specific LBP. Seventy adults with non-specific low back pain (LBP) will be recruited. Primary outcomes (pain intensity and physical functioning \[daily average\]) will be collected daily, while secondary outcomes (average pain intensity over the last week, pain-related disability, etc.) will be assessed at baseline, 3 and 9 weeks after randomization.
Eligibility
Inclusion Criteria4
- Adults between 18 and 65 years old with non-specific low back pain.
- Average pain level of ≥3 out of 10 during the previous week.
- Pain-related disability ≥10% at ODI.
- Pain relief must be present during manual traction, measured by a moderate improvement (+3) on a global rating of change scale (anchors: -7 to +7).
Exclusion Criteria11
- Specific cause of low back pain (e.g., fracture, cancer, spinal stenosis, severe spondylolisthesis)
- Presence of neuropathic pain (leg or back of 4 at the DN4).
- Pregnancy.
- Body mass index > 32.
- Waist size between 74 and 115 cm.
- Respiratory and circulatory conditions.
- Osteoporosis.
- Paraplegia and hemiplegia.
- Abdominal wounds at the site of the orthosis.
- Rib or pelvic fractures less than 3 months.
- Presence of electronic medical device.

Interventions
Participants will be advised to wear motorized lumbar support for a minimum of 4 hours and a maximum of 8 consecutive hours per day throughout the three-week study period. To reach the target of 4 hours, participants will gradually increase their daily wear time : 2 hours on the first day, 3 hours on the second day and 4 hours on the third day.
