Impaired postural control in people with non-specific low back pain; It can be affected by many factors such as pain, musculoskeletal disorders, proprioception. Postural control is important for the continuation of activities of daily living. Postural control is decreased in patients with non-specific low back pain. According to the proprioception examinations, patients with low back pain are more impaired than healthy individuals. Impaired proprioception can also reduce the ability to maintain posture, balance control and increase the load on the spine. Thus, individuals with low back pain may become more vulnerable to injuries. Weakness of the abdominal muscles and superficial trunk muscles are also risk factors for low back pain.~Weakness and fatigue may occur as a result of structural changes, which are more common in the paraspinal muscles and the multifidus muscle. This can lead to deterioration of lumbar stability. Because these muscles have an important place in providing stability.~Proprioceptive information from the hip, knee and ankle and coordination of the joints are important in maintaining and controlling balance. Regional receptors in muscles, joints, skin and tendons and proprioception in the knee joint provide the necessary joint activity and stabilization. With the decrease in balance and proprioception, pain may occur, and we may encounter a decrease in muscle strength as a result of leading a sedentary life. In this case, since the proper posture, muscle activity and balance required for coordinated movement are negatively affected, the movement is impaired. Because these activities must be performed in the correct order for the movement to occur.~In the literature, there are studies on the relationship of low back pain with muscle strength, balance and proprioception; however, the lack of sufficient studies investigating the relationship between balance and proprioception in the knee in individuals with non-specific low back pain suggests that the study to be conducted will make an important contribution to the literature and reveals the importance of our study.
The aim of this study is to examine the relationship between pain, and balance, proprioception sensation in the knee, erector spinae and multifidus muscle strength in individuals with non-specific low back pain.
