The objective of this study was to assess the effect of the core muscle strengthening and motor control exercise on pain and muscle strength in patients with chronic nonspecific low back pain. Subjects 116 were recruited and assessed using inclusion and exclusion criteria. 58 participants were randomized into either group (core muscle strengthening or motor control exercise). The Oswestry Low Back Disability Questionnaire and Computerized dynamometer were used for pre-intervention and post-intervention assessments. Core muscle strengthening (n = 58) – Two times a week for 4 weeks, in which each session was not less than 45 min long. Motor control exercise(n = 58): Similar in duration and frequency to the exercise described above. Mean value of post-test Oswestry Disability Index Scale in Group A and B was 29.57 and 21.19 respectively. The mean value of computerized dynamometer in pre-test in Group A & B was 8.942 and 11.583 respectively. This illustrates that Motor Control Exercise groups augment chronic nonspecific low back pain individuals significantly. In this study, Core muscle strengthening and Motor control exercise are both showcased to be effective as well. However, Motor control exercise shows extremely significant improvement than Core muscle strengthening in reduction of pain and improving muscle strength.
