Study Overview
Brief Summary
This study aimed to compare the effectiveness of extracorporeal shock wave therapy (ESWT) and suprascapular nerve block (SSNB) with conventional treatment for hemiplegic shoulder pain. A total of 67 patients aged 45-70 years, treated at the Department of Physical Therapy and Rehabilitation at Başakşehir Çam and Sakura City Hospital between April 1, 2023, and January 1, 2024, were randomly assigned to three groups. The first group (n=24) received conventional treatment, the second group (n=22) received conventional treatment plus one session of ultrasound-guided suprascapular nerve block, and the third group (n=21) received conventional treatment plus ESWT applied for 2 weeks, 4 days per week at 12 Hz and 2-3 bars. All groups were evaluated clinically and ultrasonographically before treatment, at 1 month, and at 3 months. Pain intensity was assessed using the visual analog scale, upper extremity motor function with the Fugl-Meyer Motor Scale, and supraspinatus muscle tear size via ultrasound.
Detailed Description
This study aimed to compare the effectiveness of extracorporeal shock wave therapy (ESWT) and suprascapular nerve block (SSNB) when added to conventional treatment in patients with hemiplegic shoulder pain.
A total of 67 patients aged 45 to 70 years who were treated at the Department of Physical Therapy and Rehabilitation at Başakşehir Çam and Sakura City Hospital between April 1, 2023, and January 1, 2024, were included in the study. Participants were randomly assigned into three groups. The first group (n = 24) received conventional treatment alone. The second group (n = 22) received conventional treatment combined with a single session of ultrasound-guided suprascapular nerve block (SSNB). The third group (n = 21) received conventional treatment combined with extracorporeal shock wave therapy (ESWT), applied for two weeks, four days per week, at a frequency of 12 Hz and an intensity of 2 to 3 bars.
All participants were evaluated clinically and ultrasonographically at baseline, at one month, and at three months. Pain intensity was assessed using the Visual Analog Scale (VAS). Upper extremity motor function was evaluated using the Fugl-Meyer Motor Scale (FMMS). Supraspinatus muscle tear size was measured using ultrasonography.

Outcomes
Primary Outcomes
Visual Analog Scale
Time Frame: Baseline, 1 month, and 3 months after treatment initiation.
The Visual Analog Scale will be used to assess the intensity of pain reported by participants. The scale consists of a 10-cm horizontal line anchored by two extremes: 0 = no pain and 10 = worst imaginable pain. Participants will mark the point on the line that best represents their pain intensity. The score will be determined by measuring the distance (in centimeters) from the "no pain" anchor to the participant's mark, with higher scores indicating greater pain intensity.
Secondary Outcomes
- Shoulder range of motion(Baseline, 1 month, and 3 months after treatment initiation.)
- Presence of supraspinatus tendon tear(Baseline, 1 month, and 3 months after treatment initiation.)
