About this study
Official title: Evaluating the Safety and Efficacy of the BTL-043 Device in Alleviating Back Pain
The study will evaluate the clinical efficacy and performance of the BTL-043 device for alleviating back pain. The study is a prospective, multi-center, open-label, single-arm study. Subjects will be required to complete four (4) treatment visits and two (2) follow-up visits. All of the study subjects will receive the treatment with the subject device. At the baseline visit, the Oswestry Disability Index (ODI), Visual Analogue Scale (VAS), and the Quebec Back Pain Disability Index (QBPDS) will be administered. The subject's weight and height will be recorded. The treatment administration phase will consist of four (4) treatments, delivered 2-10 days apart. Therapy time is set to 30 minutes for each treatment. After the last treatment, the subjects will receive the ODI, QBPDS, and the Therapy Comfort Questionnaire to fill in along with the VAS. During the 1-month and 3-month follow-up visits, the subjects will fill in the Subject Satisfaction \& Quality of Life Questionnaire, in addition to the ODI, QBPDS, and VAS. Safety measures will include documentation of adverse events (AE), which will be assessed after each procedure and at all follow-up visits.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Device: Treatment with BTL-043Device
Also called EMVITAL
All patients received four treatment sessions with BTL-043, with treatment sessions spaced 2 to 10 days apart. The treatment was applied to the upper, middle, or lower back region based on pain location. BTL-043 uses the TriHIL technology, which combines 1064 nm near-infrared laser energy at a maximum power of 30 W delivered through a hands-free applicator.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change from Baseline in the Oswestry Disability Index (ODI) Score at 3 Months
Oswestry Disability Index (ODI) The ODI will be used to evaluate the presence and impact of pain on the subjects' lives. The Oswestry Disability Index is a validated questionnaire used in assessment of back related pain and its impact on daily life. It consists of ten (10) items in total. The final score (sum of all items) is then calculated as a percentage of maximum possible points (50). The higher the percentage, the greater the disability.
Measured: Baseline and 3 months
Change from Baseline in the Visual Analogue Scale (VAS) Pain Score at 3 Months
The Visual Analogue Scale (VAS) is a self-reported measure used to assess the intensity of back pain experienced by the participants in the treatment area. Participants rate their perceived pain level on a numerical scale ranging from 0 to 10. On this scale, 0 is equivalent to "no pain" and 10 indicates the "worst possible pain". The baseline score is compared to the score collected at the 3-month follow-up visit. A negative change from baseline (a decrease in the VAS score) indicates a reduction in pain intensity and an improvement in the participant's condition over time.
Measured: Baseline and 3 months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The study will evaluate the clinical efficacy and performance of the BTL-043 device for alleviating back pain. The study is a prospective, multi-center, open-label, single-arm study. Subjects will be required to complete four (4) treatment visits and two (2) follow-up visits. All of the study subjects will receive the treatment with the subject device. At the baseline visit, the Oswestry Disability Index (ODI), Visual Analogue Scale (VAS), and the Quebec Back Pain Disability Index (QBPDS) will be administered. The subject's weight and height will be recorded. The treatment administration phase will consist of four (4) treatments, delivered 2-10 days apart. Therapy time is set to 30 minutes for each treatment. After the last treatment, the subjects will receive the ODI, QBPDS, and the Therapy Comfort Questionnaire to fill in along with the VAS. During the 1-month and 3-month follow-up visits, the subjects will fill in the Subject Satisfaction \& Quality of Life Questionnaire, in addition to the ODI, QBPDS, and VAS. Safety measures will include documentation of adverse events (AE), which will be assessed after each procedure and at all follow-up visits.
