Brief summary: This study is aimed to compare the effects of chiropractic spinal manipulative therapy and spinal decompression device treatment on lower extremity muscle strength, balance performance, lumbar range of motion and mobility, functional status, pain, and quality of life in patients with chronic low back pain.

After the approval of the ethics committee, the research was carried out in the physical therapy and rehabilitation clinic of Medipol Mega University Hospital. Individuals between the ages of 18-60, who had complaints of low back pain for the last three months and who voluntarily agreed to participate in the study were included in the study. 40 participants with low back pain existing more than 3 months were randomized into one of two groups as Chiropractic Spinal Manipulative Therapy (CSMT) and Spinal Decompression (SD). Lumbar region chiropractic HVLA (High Velocity, Low Amplitude) spinal manipulation and/or sacroiliac joint chiropractic HVLA manipulation was applied to CSMT group, and lumbar region spinal decompression (traction) device therapy was applied to SD group, and as a standard of treatment was given a hot pack for 15 minutes before applying and a cold pack for 10 minutes after applying. Both groups were treated three times with an interval of three days. Before and after treatment were evaluated lower extremity (hamstring and quadriceps) muscle strength with an isokinetic dynamometer (CSMI Humac-Norm), balance performance with BBS (Biodex Balance System), lumbar range of motion and mobility with inclinometer and hand finger floor distance (HFFD), low back pain intensity with visual analog scale (VAS), functional status with Modified Oswestry low back pain disability questionnaire (OSW), quality of life with Short form-36 (SF-36) in both groups. SPPS 25 (IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp.) version was used to analyze the data.

Detailed description: This study is aimed to compare the effects of chiropractic spinal manipulative therapy and spinal decompression device treatment on lower extremity muscle strength, balance performance, lumbar range of motion and mobility, functional status, pain, and quality of life in patients with chronic low back pain.

Chronic low back pain is a multifactorial disease that occurs especially in adults and has many negative effects on daily quality of life. This disease, which affects 70-80 percent of adults throughout their lives, creates significant limitation and high psycho-social burden in daily life due to the fact that the pain lasts more than 12 weeks. This leads to high health costs as well as loss of labor and economic burden.

The etiology of chronic low back pain varies according to the patient population, but the most common is mechanical and non-specific. 80-90 percent of low back pain is caused by mechanical low back pain, and 15-25 percent of these patients have chronic facet joint-induced low back pain caused by chronic inflammation and degeneration of the lumbar facet joints. Chronic low back pain is often thought to be caused by disc and/or vertebral degeneration, musculoskeletal sprain or strain, position of the spine, or movement-related disorders.

Limitation of movement increases due to pain and spasm seen in individuals with low back pain, and physical endurance decreases as a result of decreasing muscle strength and deteriorating posture due to non-use. As a result of this situation, the functional capacity and quality of life of individuals with low back pain are adversely affected.

In studies in individuals with low back pain, atrophy in multifidus and paraspinal muscles, delay in stimulation of the transversus abdominus muscle, decrease in hip abductor muscle strength and trigger points in the gluteus medius muscle have been shown. It has also been shown to have a decrease in hip extensor muscle strength, a decrease in hip flexion, and a significant decrease in hamstring muscle flexibility. In a study investigating knee extensor muscle strength, it was shown that the maximum voluntary contraction and isokinetic muscle strength of the knee extensors were reduced. It has been shown that individuals with chronic low back pain also have a weakened ability to balance due to decreased muscle strength, flexibility, endurance, and many physical changes.

Multifaceted treatment approaches are important because of the long-term and high cost of low back pain treatment. Medical treatment and conservative treatment (electrophysical agents, massage, traction, manipulation, exercise, etc.), public health and preventive rehabilitation programs constitute an important part of the treatment of low back pain.

Traction therapy is a broad term used to refer to any method of separation of the spine along its lower axis using mechanical force. It is used to reduce pain, especially in the cervical and lumbar regions. Traction therapy, which is one of the many treatments that mechanically drain the spine to treat chronic low back pain, has different types such as spinal traction, distraction, and non-surgical spinal decompression.

Spinal decompression (SD) therapy is a new method used as a conservative treatment for low back pain. Using movement and positioning with a traction table or similar motorized device is used to reduce pressure that can cause severe pain in the spine without any surgical procedure. Although it is generally suggested that this traction-based treatment is superior to existing classical traction devices, its basic principle is spinal distraction, which is thought to increase the distance between interververtebral discs by relaxing neural structures with its mechanical effects . Disc herniation or bulging creates a negative intervertebral pressure for the withdrawal and repositioning of disc material, and thanks to low pressure, it increases the fluid in the disc and the flow of fluids that nourish the disc.

Chiropractic consists of the Greek words chiro (hand) and practic (practice) and means "manual practice." Chiropractic, which is an evidence-based primary health care, is generally preferred by people with low back and neck pain in developed countries. In biomechanical disorders of the musculoskeletal and spinal systems that have not reached the surgical level, the complex of vertebral subluxation caused by isolated axis disorders, mechanical movement integrity and disruption of physiological functions or their negative effects on the nerve, muscle, ligaments, circulation and movement systems Chiropractic manipulations applied for the purpose of correction are an easy-to-apply, non-invasive, cost-effective and low form of treatment with side effects.

Although there are many studies in the literature in which the effects of conservative treatments used in the treatment of individuals with chronic low back pain are independently examined or compared with each other, there have been no studies comparing chiropractic manipulation and non-surgical spinal decompression treatments.

After the approval of the ethics committee, the research was carried out in the physical therapy and rehabilitation clinic of Medipol Mega University Hospital.
