The purpose of the study was to find out the effect of trunk extensor endurance protocol versus Pilates techniques in chronic low back pain related disability in motor cycle riders for duration of 6 weeks. 100 participants (only males) were divided into two groups, 50 in each group, ranging from 20-40 years old, along with inclusion criteria were randomly selected. Trunk extensor endurance protocol was given for 24 sessions over 6 weeks, i.e. 4 times weekly⁴. Pilates were given 12 sessions 2 times weekly⁸. The subjects were evaluated before and after the 6 weeks. Oswestery low back pain disability questionnaire was to assess the effect of trunk extensor endurance protocol and Pilates technique. Statistical analysis of the data was done and significant improvement in the Oswestery low back pain disability questionnaire Test Scores (p<0.05) was noted. Hence, these results suggest that after 6 weeks, Pilates Technique proved more effective on chronic low back pain related disability in motorcycle riders than trunk extensor endurance protocol.
