Effectiveness of Muscle Energy Technique As Compared to Maitland Mobilisation for the Treatment of Chronic Sacroiliac Joint Dysfunction

Objective: To compare the effectiveness of Muscle Energy Technique (MET) with Maitland mobilisations when using lumbopelvic stability exercises as an adjunct therapy with them in reducing pain and disability in patients with sacroiliac joint dysfunction (SIJD).

Methodology: A randomised controlled trial was conducted at physical therapy departments of Khyber Teaching Hospital, Lady Reading Hospital and Rehab Polyclinic, Peshawar, Pakistan and comprised of data over a to a six-month period from January 2015 to June 2015. Sixty participants (both male and female with an age range of 25-55 years) were randomly assigned to two equal groups of 30 (50%) each by chit-box method. Group-A of 30 patients (experimental group) was treated with Muscle Energy Technique (MET). Group-B of 30 patients (control group) was treated with Maitland Mobilizations at sacroiliac joint. Lumbopelvic stability exercises were given to both groups. The treatment outcomes were measured on the first day and then after 4 weeks (12 sessions) from each subject's pain and disability levels by using Visual Analogue Scale (VAS) for measuring pain and Modified Oswestry Disability Index (MODI) for measuring disability.

Results: The paired sample statistics for intra-group analysis of the VAS and MODI showed a significant difference in values i.e. for Group-A, VAS was 16.699 with p-value 0.000 and MODI was 29.125 with p-value 0.000 while for Group-B, VAS was 18.687 with p-value 0.001 and MODI was 28.607 with p-value 0.001. The independent samples test for inter-group analysis of pre-VAS and post-VAS were 0.662 with 0.510 p-value and 1.000 with 0.321 p-value respectively while of pre-MODI and post-MODI were -1.482 with 0.144 p-value and -0.114 with 0.909 p-value respectively This showed an insignificant difference in pain and disability outcomes between the groups.

Conclusions: MET and Maitland mobilisations are both effective in treating the chronic sacroiliac joint dysfunction when using lumbopelvic stabilisation exercises as an adjunct therapy with them.
