About

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.

Full 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.

  1. Patients who cannot express their own pain intensity.

  2. Patients with a history of trauma or surgery to the shoulder on the affected side.

  3. Patients with history of oral NSAIDs 3 days before this study or take warfarin medication with an international normalized ratio above 4.0.

  4. Patients with a history of shoulder pain before the stroke.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

30 participants in 2 patient groups

study group

Active Comparator group

Description:

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.

Treatment:

Device: radial extracorpeal shock wave

control group

Sham Comparator group

Description:

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

Treatment:

Device: radial extracorpeal shock wave
