Addressing sleep problems in patients with chronic non-specific low back pain (LBP) can reduce chronic pain, the risk of developing depressive illness and improve pain-related quality of life.~Sleep is a concept that has physiological, psychological, and social dimensions. Sleep is one of the essential and indispensable daily life activities that affect individuals' quality of life and well-being. Decreasing pain is expected and likely to improve sleep quality. Still, it is unknown what will happen due to improving sleep quality to resolve the pain of unknown origin.~Education about sleep hygiene with physiotherapy has not been assessed before on individuals with nonspecific LBP. Since this training will require a lifestyle change, individuals should be warned not once but several times in a certain time, and this training should be reinforced. This will be an advantage for the patients receiving physiotherapy, and their therapists will support them in applying this training during the physiotherapy sessions.~In our study, individuals with nonspecific chronic low back pain will be divided into three groups using the blinding method as part of a randomized controlled trial.~The first group, as the conventional physical therapy group, will receive a hot pack and TENS only.~The second group, as the stabilization group, will receive lumbar stabilization exercises and the conventional physical therapy program.~The third group, as the breathing exercise group, will receive breathing exercises, including sleep hygiene and stabilization group program.
The aim of this study is to compare the effect of sleep hygiene, breathing exercises, and stabilization exercises on pain, sleep quality, and anxiety level in patients with non-specific chronic low back pain.
