Aims: To determine the efficacy of strain counterstrain (SCS) technique and muscle energy technique (MET) in limiting pain and disability among individuals with mechanical low back pain. To identify an effective treatment for earlier recovery from mechanical back pain to prevent further aggravation of the condition. Settings and Design: Randomized double-blinded study design in which 90 subjects were recruited using simple random sampling from 180 community dwelling mechanical low back pain subjects. Forty-five subjects randomized into each groups. Mean age of Groups A and B subjects were 37 and 40 years, respectively. Double blinded baseline and post interventional assessment was performed. Intervention includes moist hot pack for both groups, with group A receiving SCS and group B receiving MET. Outcome measures were visual analog scale (VAS), Modified Oswestry Disability Index, and lumbar flexion range of motion (ROM) using modified Schober's test. Statistical Analysis and Results: Data was coded and entered using EPI INFO version 3.5.1 and exported to Statistical Package for Social Sciences (SPSS) version 16. Statistical evidences suggest that Group B (MET) showed significant prognostic changes with all outcomes (P <0.0001) at 3 months. But, Group A (SCS) showed significant changes only with Schober's test and no trends favoring treatment were found with VAS and Modified Oswestry Disability Index. Conclusion: Hot moist pack with MET was effective in alleviating mechanical low back pain in terms of pain, increases in lumbar ROM, and reduces disability.
