Low back pain is a common condition that affects 70% of people at least once. Sacroiliac joint Dysfunction (SIJD) is a skipped health problem that is ignored in patients with low back or hip pain. Fluoroscopy-guided SIJ injection showed that SIJD is a source of pain in 13-30% of patients with chronic low back pain. Inadequate function of SIJ leads to abnormal gait pattern, pain during walking, increase in load on discs, long-term interdisciplinary stability and causing to increase of the listhesis. The pain worsens with running, climbing stairs or standing up from the sitting position. Pharmacological, non-pharmacological and if required surgical treatment may be applied in the osteoarthritis treatment. Non-pharmacological treatment includes patient education, exercise, massaging, SIJ, manipulation-mobilization, chiropractic applications, physical therapy modalities, use of the assistive device.

Kinesio Taping is a treatment that has not been studied much and can be applied in SIJD. When investigators reviewed the literature, investigators found a study and a case report investigating the activity of Kinesio taping in sacroiliac joint dysfunction. Although the mechanism of Kinesio taping cannot be understood, it is claimed that it has four beneficial effects: normalizes muscular function, improves blood and lymphatic circulation, reduces pain, regulates possible disorders of joints. In studies showing the effectiveness of Kinesio banding in the reduction of pain in health problems related to the waist area with the highest number of publications, it was noted that the pain was reduced rapidly within three days, decreased the need for analgesics within two weeks and increased function in daily living activities.

The study is a randomized, controlled study. 52 participants will be included to study who apply to Dokuz Eylül University Faculty of Medicine, Department of Physical Medicine and Rehabilitation Clinic with the complaint of hip and back pain, aged between 18-60 years. Participants have diagnosed as Sacroiliac Joint Dysfunction according to The International Association for the Study of Pain (IASP) diagnostic criteria. These participants will be divided into two groups randomly (Treatment group n:26, control group n:26). Because the therapeutic effect may be seen with unsealed banding in Kinesio taping and the placebo effect may not be evaluated, After the last evaluation, participants in both groups will be given the necessary treatment and since there is no study on this subject in the literature, no treatment was given to the control group due to the fact that the actual effect of banding was desired. The treated group received Kinesio taping 3 times at 5-day intervals, one of the fan-shaped cut bands, 2-3 inches above the SIJ, and the other below 2-3 inches below the SIJ, and crossed each other by 90 degrees. Both groups were evaluated at baseline and on the 15th day by physical examination of the sacroiliac joint, visual analog scale, Modified Oswestry Pain Inquiry Form. The kinesiological taping group was also evaluated with VAS and positive SIJ pain provocation tests, 20 minutes after the first banding, to assess the acute effect.
