NSLBP can cause impairment in motor control, which is the ability of the body to execute a precise and stabilized movement in space. Many factors affect motor control dysfunction and lead to different physical impairments, consequently requiring different approaches in clinical settings. However, the study regarding the alteration of motor control and the factors coming with NSLBP are still limited.
