The Effects of EXOPULSE Mollii Suit on Low Back Pain (EXOBACK)" / EXOPULSE Mollii Suit and Low Back Pain (EXOBACK)

Обзор

Low back pain is a common musculoskeletal problem. It is the main cause of activity limitation and work absence and carries a huge medical burden and economic cost. Low back pain is considered "chronic" when it persists for more than 3 months. Chronic low back pain affects daily activities and constitutes a psychological burden, which could lead to anxiety and/or depression. Prevention of low back pain is recognized as a pivotal challenge in high-risk populations to help tackle high healthcare costs related to therapy and rehabilitation. Current pharmacological drugs, namely anti-inflammatory and narcotics medications, have limited efficacy and numerous side effects. In addition, most available treatment options only address single, targeted causes; however, given the complexity of low back pain, a multi-modal interdisciplinary approach is highly needed. Transcutaneous electrical nerve stimulation (TENS) is a safe alternative to current treatments. Many studies have shown its efficacy and benefit in reducing pain. However, it only targets a limited number of muscles. For this reason, transcutaneous stimulation using the EXOPULSE Mollii suit might help reduce pain and related outcomes in this context since it simultaneously targets several muscle groups.

Вмешательства

• Устройство EXOPULSE MOLLII SUIT (active)
  Exopulse Mollii suit is a new assistive device that has been developed by Exoneural Network (initially Inerventions AB), a Swedish med-tech company. Exopulse Mollii suit is a full-body garment with integrated 58 electrodes that can transcutaneously stimulate several groups of muscles. The device is CE labelled and is intended to use for reducing spasticity and improving blood circulation. The outfit is very easy to put on, it can be used for one hour every day and the analgesic effects last 24
• Устройство EXOPULSE MOLLII SUIT (sham)
  It consists of applying the same parameters used for the active session (low frequency: 20 Hz; current intensity: 2 mA; pulse width ranging from 25 to 175 µs) but for a shorter duration of time (1 minute).

Первичные конечные точки

• Pain-related disability reduction will be assessed using the QBPDS (Quebec Back Pain Disability Scale) before and after active and sham stimulation [Срок оценки: This will be assessed through study completion, an average of 3 months at Visit 1(Day 0) , Visit 2 (Day 15), Visit 3 (Day 30), Visit 4 (Day45), Visit 5 (Day 60) and Visit 6 (Day 90)]

Вторичные конечные точки (9)

• Assessment of pain-related disability reduction using the ODQ (Owestry Disability scale) [Срок оценки: This will be assessed through study completion, an average of 3 months (at Visits 1, 2, 3, 4, 5 and 6)]
• Analgesic effects based on the VAS (Visual Analogue Scale) [Срок оценки: This will be assessed through study completion, an average of 3 months (at Visits 1, 2, 3, 4, 5 and 6)]
• Analgesic effects based on the Brief Pain Inventory (BPI) [Срок оценки: This will be assessed through study completion, an average of 3 months (at Visits 1, 2, 3, 4, 5 and 6)]
• Analgesic effects based on the Pain Catastrophizing Scale (PCS) [Срок оценки: This will be assessed through study completion, an average of 3 months (at Visits 1, 2, 3, 4, 5 and 6)]
• Assessment of anti-fatigue effects according to VAS (visual analogue scale) [Срок оценки: This will be assessed through study completion, an average of 3 months (at Visits 1, 2, 3, 4, 5 and 6)]
• Mood symptoms will be evaluated using the Hospital Anxiety and Depression Scale (HADS) [Срок оценки: This will be assessed through study completion, an average of 3 months (at Visits 1, 2, 3, 4, 5 and 6)]
• Improvement of the quality of life using the Short Form 36 Health Survey (SF-36) [Срок оценки: This will be assessed through study completion, an average of 3 months (at Visits 1, 2, 3, 4, 5 and 6)]
• Evaluation of overall improvement using the CGI (Clinical Global Impression) [Срок оценки: This will be assessed at Visit2 (Day 15) , Visit4 (Day 45) and Visit6 (Day 90) since CGI is designed to be applied after interventions]
• Evaluation of patient's blinding to the type of stimulation in the crossover trial [Срок оценки: This will only be assessed at Visit2 (Day 15) and Visit4 (Day 45) of Phase 1.]
