ارزيابي تاثير دو روش درماني مانيپولاسيون ستون فقرات و التراسوند در بيماران مبتلا به كمردرد با استفاده از اكتروميوگرافي سطحي

Background and purpose: Despite extensive investigations, application of surface electromyography (SEMG) in the evaluation of rehabilitation programme for the patients suffering from chronic low back pain (CLBP) has yet to be conclusively demonstrated. in a randomised controlled trial, effectiveness of spinal manipulation therapy (SMT) compared with therapeutic ultrasound (US) in the treatment of CLBP was investigated using SEMG. One of the purposes of this study was to assess the short and long-term effectiveness of SMT and US on CLBP and also to identify the effect of SMT on lumbar muscle endurance. Materials and methods: After ethical approval, 120 patients with CLBP were randomly divided in two experimental and control groups. Pain intensity, functional disability and back muscle endurance using SEMG were measured shortly before treatment, at the end of the treatment and six months after randomisation. Results: Following treatment, significant changes (P<0.01) have been recorded for both groups, statistical analysis of the data obtained from this study in order to determine the difference between these two groups has shown that the rate of improvement in the experimental groups was more than control group (P<0.01); and this difference was significant in multifidus muscle. Both groups benefited from the treatment interventions at six months follow up and the patients in the experimental group showed greater improvement. Conclusion: This study shows that SEMG approach as a non-invasive tool can be used in evaluating treatment technique. Also it has been proved that, both of these treatment techniques have been useful in the patients with chronic back pain, and the patients who received SMT technique showed more improvement.
