Muscle Energy Technique Versus Maitland Mobilization on Shoulder Pain and Disability

Study Overview
=================
Brief Summary
-----------------
The purpose of this study was to investigate the effect of muscle energy technique versus Maitland's mobilization on shoulder pain and disability after neck dissection surgeries.

Detailed Description
-----------------
Thirty patients with shoulder pain and limited ROM post-neck dissection surgeries participated in this study. Patients were subdivided into two groups, fifteen patients in each group. Group A received the muscle energy technique and group B received Maitland's mobilization. Data obtained from both groups regarding Visual Analogue Scale (VAS), The Shoulder Pain and Disability Index (SPADI), and shoulder flexion, abduction, and external ROM were statistically analyzed and compared.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Muscle energy technique<br>This group includes 15 patients who received muscle energy technique post-surgery in addition to traditional shoulder exercise, 3 sessions/week for four weeks. | Other: Muscle energy technique<br>* It was applied on the shoulder flexion and the external rotation. An isometric contraction of the agonist muscle (the muscle which requires stretching) for 7 seconds with gentle muscle contraction to avoid the risk of increasing the muscle tone. This contraction started just short of the restrictive barrier. After that, the patient is asked to relax for 2-3 seconds and then the therapist stretches the contracted muscle in the opposite direction for 30 seconds. This is repeated three repetitions for each muscle.<br>Other: Traditional shoulder exercise<br>* Traditional shoulder exercises in the form of shoulder range of motion exercises, stretching exercises and, scapular stabilization.<br>|
| Active Comparator: Maitland mobilization<br>This group includes 15 patients who received mobilization in addition to traditional shoulder exercise, 3 sessions/week for four weeks. | Other: Maitland mobilization<br>* At the start of each session, the physical therapist examined the patient's ROM in all directions to obtain information about the end-range position and the end feel of the glenohumeral joint. Start with rhythmic mid-range mobilization with the patient in a supine position. The therapist's hands are placed close to the glenohumeral joint, and the humerus is brought into a position of maximal flexion in the sagittal plane. After 10 to 15 repetitions of intensive mobilization techniques in this end-range position, the direction of mobilization will be altered by varying the plane of elevation or by varying the degree of rotation. When alternating the direction of mobilization, other movements such as gliding techniques and distraction in that joint position were (inferior gliding, anterior gliding, and posterior gliding).<br>Other: Traditional shoulder exercise<br>* Traditional shoulder exercises in the form of shoulder range of motion exercises, stretching exercises and, scapular stabilization.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Visual analogue scale (VAS) | A Visual Analogue Scale (VAS) is one of the pain rating scales used for the first time in 1921 by Hayes and Patterson. It is often used in epidemiology and clinical research to measure the intensity or frequency of various symptoms. | Change from baseline at four weeks after the intervention | 
| The SPADI (Shoulder Pain and Disability Index) | It is a self-reported questionnaire consisting of 13 items divided in two parts: pain and disability sub-scale. | Change from baseline at four weeks after the intervention | 
| Shoulder active range of motion | Through using the universal goniometer to measure the shoulder flexion, abduction and, external rotation. | Change from baseline at four weeks after the intervention |
