Non-surgical Spinal Decompression Therapy and Outcomes

Participants who consent to the study will undergo a comprehensive baseline assessment. Baseline: During this visit, the patient will receive a chiropractic physician examination that will include reflexes, myotome, dermatome, and orthopedic assessments. If the examination provides evidence of an intervertebral disc pathology and/or sciatica, the patient will be referred to an MRI assessment to confirm diagnosis for standard of care. Based on these assessments, the research team will determine if the participant meets the initial criteria to continue with participation. Randomization: Participants will be randomized to either non-surgical spinal decompression (20 treatments) or placebo (20 treatments). Participants will not be able to choose the treatment. The participant nor the investigators will know which treatment you are receiving. If a participant receives the placebo treatment, once they are unblinded, they will be able to receive non-surgical spinal decompression should they elect to do so. Pre-intervention Assessments: Assessments prior to intervention will include 1) 3D motion capture performing functional tasks, 2) electromyography of the lower back and legs, 3) myotonometer tonometry, 4) range of motion, and 5) Sensorimotor reflex measurement. In addition, the participant will complete online questionnaires that include the Defense Veterans Pain Rating Scale 2.0, PROMIS Pain Interference, PROMIS Physical Function, Central Sensitization Inventory, and the Oswestry Disability Index. Post-intervention Assessments: Assessments after intervention will include 1) 3D motion capture performing functional tasks, 2) electromyography of the lower back and legs, 3) myotonometer tonometry, 4) range of motion, and 5) Sensorimotor reflex measurement. In addition, the participant will complete online questionnaires that include the Defense Veterans Pain Rating Scale 2.0, PROMIS Pain Interference, PROMIS Physical Function, Central Sensitization Inventory, and the Oswestry Disability Index.
