Comparison of different electrotherapy methods and exercise therapy in shoulder impingement syndrome: A prospective randomized controlled trial

摘要

Objective The aim of this study was to assess and compare the effects of different electrotherapy methods and exercise therapy on pain, function and quality of life in shoulder impingement syndrome. Methods Eighty-three patients (66 females, 17 males; mean age: 48.2?±?7.33 years) with shoulder impingement syndrome were selected and 79 of them were randomly allocated into four groups. Group 1 (n?=?19, mean age: 47.89?±?7.12 years) was given hot pack and exercises, Group 2 (n?=?20, mean age: 47.70?±?6.51 years) was given hot packs, exercises and interferential current, Group 3 (n?=?20, mean age: 48.50?±?8.34 years) was given hot packs, exercises and TENS and Group 4 (n?=?20, mean age: 48.55?±?7.89 years) was given hot packs, exercises and ultrasound three times a week for four weeks. Assessments were made before treatment, right after it and three months after that using the visual analog scale (VAS), Short Form-36 (SF-36) and the Disabilities of the Arm, Shoulder and Hand (DASH) outcome measures. Results At the fourth week and third month assessments, all groups showed significant improvements in terms of pain, DASH and SF-36 physical component scores (p? 0.05). Conclusion Application of ultrasound, interferential current and TENS in addition to exercise therapy in shoulder impingement syndrome treatment had similar improvements in terms of pain, function and physical component of quality of life. However, interferential current treatment showed significantly better outcomes for the mental component of quality of life. Level of evidence Level I, Therapeutic study.
