Effects of Muscle Energy Technique Versus Aerobic Exercises on Pain and Disability in Patients With Chronic Pelvic Pain


The aim of study is to find out the effects of muscle energy technique versus aerobic exercises on pain and disability in patients with chronic pelvic pain.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: Triple (Participant, Investigator, Outcomes Assessor)
  • Study Primary Completion Date: July 1, 2022


  • Other: Muscle Energy Technique
    • Muscle energy technique (Post Isometric relaxation) three times per week for 8 weeks. MET of the Iliopsoas MET of Piriformis muscle MET of Quadratus Lumborum muscle MET of Erector Spinae muscle
  • Other: Aerobic Exercises
    • Aerobic exercise (treadmill walking) three times per week for 8 weeks Warm-up phase: in which each patient alternately steps their legs forward, backward, and sideways in each direction for 5 min Active phase: Treadmill speed was 3km/hour for 5 weeks and progress to 4km/hour after 5 weeks for 20 min. Cool down phase: During a cool down period take a deep breath with both arms overhead and exhale while bringing the arms down, shaking out the legs and arms for 5 min.

Arms, Groups and Cohorts

  • Experimental: Muscle Energy Technique
    • Muscle Energy Technique of Iliopsoas, Piriformis, Quadratus Lumborum and Erector Spinae muscle
  • Experimental: Aerobic Exercises
    • aerobic exercises (walking on the treadmill)

Clinical Trial Outcome Measures

Primary Measures

  • Pelvic pain impact questionnaire
    • Time Frame: 8th week
    • The Pelvic Pain Impact Questionnaire evaluates the pelvic pain impact on life. It has patient generated language, is easily managed and scored, has psychometric properties and it is appropriate for clinical settings and research across primary, secondary and tertiary care. The ten-item questionnaire consist of 8 Likert questions and 2 additional, non-scored questions
  • Numerical Pain Rating Scale
    • Time Frame: 8th week
    • The Numerical Pain Rating Scale (NPRS) is a particular measure in which people rate their pain on an 11-point numerical scale. The scale is comprised of 0 (no pain at all) to 10, 0 show no pain at all and 10 indicate worst imaginable pain

Secondary Measures

  • Pain disability index
    • Time Frame: 8th week
    • The Pain Disability Index is a seven-item survey to investigate functional disability. Every question utilizes an ordinal scale going from 0 to 10, 0 indicates no disability and 10 means worst disability. Scores can be added to represent a combined score of worldwide disability ranging from 0 to 70 ,where higher scores indicate greater disability
