ESWT: Effect of Extracorporeal Shock Wave Therapy in Impingement Syndrome
Study Details
Study Description
Brief Summary
Purpose: This study aimed to investigate the effectiveness of ESWT applied to trigger points on pain, function, and effusion in individuals diagnosed with shoulder impingement syndrome.
Material and methods: This was a randomized controlled clinical trial with a total of 32 which were randomly divided into two equal groups (ESWT Group (EG), n = 16; Control Group (CG), n=16). The participants in the EG were given Extracorporeal Shock Wave Therapy to the trigger point of the patients with a trigger point in one of the supraspinatus, subscapularis and infraspinatus muscles for a total of 5 sessions in 3 weeks (2 sessions in the first week, 2 sessions in the second week, 1 session in the third week) in addition to conventional treatment while CG received only conventional treatments for five days per week for 3 consecutive weeks. The primary outcome was pain intensity Visual analog scale (VAS). Secondary measurements were Tendon thickness and effusion with Ultrasound, Range of motion (ROM), Manual muscle testing (MMT), Corbin posture analysis, Constant Murley Score (CMS), Arm Shoulder and Hand Problems Questionnaire (DASH). Supraspinatus tendon thickness and effusion of the cases included in the study were evaluated by ultrasonography before and after the treatment(3 weeks) by the same specialist physician who was blind to the groups. Normal joint range of motion by universal goniometer, muscle strength by manual muscle test, posture evaluation by Corbin posture analysis, pain evaluation by Visual Analogue Scale (VAS), functional evaluation by Constant Murley Score (CMS), Arm Shoulder and Hand Problems Questionnaire (DASH) by physiotherapist It was evaluated before and after the treatment (3 weeks).

This study aimed to investigate the effectiveness of ESWT applied to trigger points on pain, function, and effusion in individuals diagnosed with shoulder impingement syndrome.
This was a randomized controlled clinical trial with a total of 32 which were randomly divided into two equal groups (ESWT Group (EG), n = 16; Control Group (CG), n=16). The participants in the EG were given Extracorporeal Shock Wave Therapy to the trigger point of the patients with a trigger point in one of the supraspinatus, subscapularis and infraspinatus muscles for a total of 5 sessions in 3 weeks (2 sessions in the first week, 2 sessions in the second week, 1 session in the third week) in addition to conventional treatments , while CG received only conventional treatment for five days per week for 3 consecutive weeks. Conventional treatment consist of Ultrasound treatment (Gymna Pulson200) (1 mHz. treatment dose average 1.5 w/cm², intermittent with a small head (50%), 5 minutes ) around the glenohumeral joint of the cases in both groups participating in the study; at an intensity that the patient can tolerate, covering the painful area TENS (modified biphasic asymmetric pulse, and it was set to a pulse width of 100 μs and a frequency of 100 Hz, 20 min,) (Hometech ht 66b) applied; hotpack and exercises (posterior capsule stretching, wand exercises, mobilization approximately 60 minutes of conventional treatment consisting of exercises and shoulder isometric exercises) was applied once a day, 5 times a week in both groups. In addition to conventional physiotherapy. additional to conventional treatment EG was applied 1000 pulses to the trigger point of the patients with a trigger point in one of the supraspinatus, subscapularis and infraspinatus muscles, 500 pulses to the surrounding area, 2 bars, ESWT (GYMNMA Shockmaster 500) was applied for a total of 5 sessions in 3 weeks (2 sessions in the first week, 2 sessions in the second week, 1 session in the third week) at 10 Hz, medium energy level (<0.28 mJ/mm2).Supraspinatus tendon thickness and effusion of the cases included in the study were evaluated by ultrasonography before and after the treatment(3 weeks) by the same specialist physician who was blind to the groups. Normal joint range of motion by universal goniometer, muscle strength by manual muscle test, posture evaluation by Corbin posture analysis, pain evaluation by Visual Analogue Scale (VAS), functional evaluation by Constant Murley Score (CMS), Arm Shoulder and Hand Problems Questionnaire (DASH) by physiotherapist It was evaluated before and after the treatment (3 weeks).

Outcome Measures
Primary Outcome Measures
- Pain intensity [3 week]
The Visual Analog Scale that is highly feasible for clinical research and practice to assess pain intensity was scored by means of a 10-cm long horizontal line ranging from (0 cm = no pain) at one end to (10 cm = maximum imaginable pain) at the other on which participants marked a point according to their subjective perception of pain
Secondary Outcome Measures
- Thickness of supraspinatus tendon [3 week]
Ultrasound is a reliable method of assessing the thickness of the tendon and having the advantages of being readily available, highly sensitive, relatively inexpensive, and non-invasive. The settings of the US system were standardized for all participants and remained the same for all measurements.
- Effusion in shoulder [3 week]
Ultrasound is a reliable method of assessing the thickness of the tendon and having the advantages of being readily available, highly sensitive, relatively inexpensive, and non-invasive. The settings of the US system were standardized for all participants and remained the same for all measurements.
- Shoulder ROM (flexion,extension,abduction,adduction,internal rotation,external rotation) [3 week]
The standard (universal) goniometer that is low cost, affordable, easy to be employed measurement tool to measure for range of motion in clinical evaluations of patients (33, 34). Universal 31-centimeter plastic 180° goniometer was used
- Shoulder muscle strength [3 week]
The manual muscle test (MMT) is a flexible diagnostic tool, which is used to assess muscle strength, a "muscle power function" according to the International Classification of Functioning, Disability, and Health is defined herein as the maximum voluntary resultant output that muscles can bring to bear on the environment under a specific set of test conditions (35). 6-degree scale ranging from palsy ("Gone-no contraction felt") up to full power ("normal-muscle can hold the test position against strong pressure''
- Corbin posture analyze [3 week]
Corbin Posture Analysis is a method in which postural changes are analyzed by observing the patient's current position. Analyzes are performed from lateral and posterior perspectives, and posture is scored according to the severity of the abnormality (0 = none, 1 = mild, 2 = moderate, 3 = severe). Postural scores obtained by posterior and lateral observation are summed and graded as poor ≥12, fair 8-11, good 5-7, very good 3-4 and excellent 0-2.
- Constant Murley Score [3 week]
The CMS is a standardized, a relatively unique, simple clinical method of assessing shoulder function and has a maximum score of 100 points, with both subjective (35 points) and objective (65 points) components for various shoulder pathologies (38). The subjective parameters assess the degree of pain perception (15 points) and the ability to perform the normal tasks of daily living in both activity- and position-related terms (20 points). The objective parameters include testing of active range of motion (40 points) and muscle strength (25 points). The calculation of the score is simple and easy. A higher score corresponds to better shoulder function.
- DASH [3 week]
The Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire is the most commonly applied patient-reported outcome measure used to measure physical, psychological and social role function in clinical research and practice for patients with injuries and diseases of the upper extremities. The main component of the DASH is a 30-item scale concerning the patient's health status during the preceding week: 21 items regarding the degree of difficulty in performing certain physical activities; five items pertaining to the severity of pain, activity-related pain, tingling, weakness, and stiffness; and four items concerning the effect that the upper limb problem has had on social activities, work, sleep, and self-image. Each item is scored on a five-point ordinal scale. the DASH score results are inverted with the higher scores (maximum = 100) representing a greater disability and the lower scores occurring in a good functioning arm
