Influence of Radial Extracorpeal Shock Wave in Hemiplegic Shoulder Patients

Not Applicable

Completed

• Conditions: Hemiplegia; Spastic
• Interventions: Device: radial extracorpeal shock wave

• Registration Number: NCT04859673
• Lead Sponsor: Delta University for Science and Technology

Brief Summary

The purposes of this study are to examine sonographic structural changes pre and post the radial extracorporeal shock wave intervention in hemiplegic shoulder pain, and to assess the relationships between sonographic structural changes and hemiplegic shoulder pain.

Detailed Description

Painful shoulder is a common complication following hemiplegic stroke. This pain may interfere with functional improvement, the patient's quality of life, and it may impede the process of rehabilitation. Further understanding of rotator cuff tendon impairment and other shoulder soft tissue structural abnormalities in stroke patients may help clinicians in assigning more complete therapeutic plans to hemiplegic patients. The radial extracorporeal shock wave therapy has promising results in patients with musculoskeletal problems and in those with various causes of HSP, including spasticity, rotator cuff problems, adhesive capsulitis, and complex regional pain syndrome .The purposes of this study are to examine sonographic structural changes pre and post the radial extracorporeal shock wave intervention in hemiplegic shoulder pain, as well as to explore the relationships between sonographic structural changes and hemiplegic shoulder pain. This study will be a benefit in the physical therapy field and may guide rehabilitation programs of physical therapy towards better results through decreasing time needed to perform activity of daily living, decreasing dependency and making patient an active member in society.

Arm && Interventions

Group	Intervention	Description
control group	radial extracorpeal shock wave	The patients in this group will be treated by sham radial extracorporeal shock wave therapy. Stimulation will not deliver as the transmitter head will be removed. The patients will receive the same frequency of air pressure and sound
study group	radial extracorpeal shock wave	Patients will received 3,000 pulses, 1,500 pulses per site at a frequency of 12 Hz per session with the submaximal pressure between 0.39 and 1.95 mJ/mm2 (1.0 and 5.0 bar), depending on the level which the patient can tolerate without local anesthetics.

Primary Outcome Measures

Name	Time	Method
Evaluation of hemiplegic shoulder structural changes by ultrasonography	Baseline	Ultrasonography evaluation includes long head of biceps tendon ,subscapularis tendon, supraspinatus tendon, infraspinatus tendon. Each abnormal ultrasound (US) finding will be assigned a score of one (1) if present or zero (0) if absent. Long head of biceps effusion, sub acromial sub deltoid bursa effusion, subluxation, and adhesive capsulitis scored. Tendon tear, tendinosis, and tendon degeneration will be similarly scored for each of the four examined tendons per shoulder. The sum of these scores yielded a raw ultrasound (US) score; such that the minimum score was zero (normal examination) while the maximum score amounted to sixteen .The raw US scores will be further grouped into graded US scores, such that scores of 0, 1-2, 3-4, 5-6, and more than 6 abnormal sonographic findings represented normal shoulder, mild damage, moderate damage, severe damage, and intense damage, respectively

Secondary Outcome Measures

Name	Time	Method
Pain assessment by using shoulder pain and disability index (SPADI).	Baseline	Shoulder pain and disability index is a shoulder specific self-reported questionnaire measuring pain and disability in patients with shoulder pain. It contains 5 items assessing pain and 8 items assessing shoulder function. Each item is scored on visual analogue scale with (Right end) defined as "worst pain imaginable/ so difficult required help", (Left end)"no pain/no difficulty". Scores will be calculated as follow, in part one pain scores in all questions will be added, and the mean value will be chosen. In part two functional scores of all questions will add and the mean value will be chosen for the purpose of data analysis. Final score for each part will be statistically analyzed separately
