Lumbar stiffness is a common complaint of patients with low back pain. The Muscle Energy Technique (MET) is a common intervention to treat the spine and sacroiliac joint dysfunctions and their resulting disability in daily activities. This research aimed to evaluate the effects of MET on pain, functional disability, and lumbar stiffness of patients with sacroiliac joint dysfunctions by considering the type of dysfunction and the orientation of the correcting maneuver.
Fifty women with ant innominate or post innominate dysfunctions were recruited for the research and randomly divided into two groups (n=25). One group received one session of MET, and the other group received the sham position. Visual Analogue Scale (VAS), lumbar Stiffness Disability Index (SDI) and Oswestry Disability Index (ODI) were used for the evaluation of the participants before, 24 hours after and one week after the intervention.
According to the results, MET significantly decreased the mean range of VAS and ODI, 24 hours, and a week after the intervention (P<0.01). We did not see any significant difference in SDI values before, 24 hours, and one week after MET in the patients (P>0.01).
Applying MET regarding the kind of dysfunction may reduce the patient’s pain and disability.
