Study 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.

Read the 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.

Study arms

  • Active comparator
    Conventional Treatment

    Participants received conventional therapy including transcutaneous electrical nerve stimulation, hot pack therapy and joint range of motion, stretching, and progressive resistive exercises

    Other: Conventional therapy group

  • Experimental
    Suprascapular Nerve Block plus Conventional Treatment

    Participants received one session of ultrasound-guided suprascapular nerve block prior to conventional therapy, followed by the same conventional treatment protocol.

    Procedure: suprascapular nerve block

  • Experimental
    ESWT plus Conventional Treatment

    Participants received extracorporeal shock wave therapy in addition to the conventional treatment protocol.

    Device: Extracorporeal Shock Wave Therapy

Interventions

  • OtherConventional therapy group

    Conventional treatment including transcutaneous electrical nerve stimulation, hot pack therapy for 4 weeks, and joint range of motion, stretching, and progressive resistive exercises performed 5 days per week for 12 weeks.

  • Proceduresuprascapular nerve block

    A single session of ultrasound-guided suprascapular nerve block administered prior to the conventional therapy program.

  • DeviceExtracorporeal Shock Wave Therapy

What researchers measure

Primary outcomes

  1. Visual Analog Scale

    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.

    Time frame: Baseline, 1 month, and 3 months after treatment initiation.

Secondary outcomes

  1. Shoulder range of motion

    Maximum passive shoulder flexion, abduction, internal rotation, and external rotation, as well as the range of motion at pain onset, were measured using a goniometer while the patient was in the supine position. Measurements were recorded in degrees, and higher values indicate greater joint range of motion.

    Time frame: Baseline, 1 month, and 3 months after treatment initiation.

  2. Presence of supraspinatus tendon tear

    The presence of a supraspinatus tendon tear was evaluated using ultrasonography with a branded ultrasound device. Imaging was performed by an experienced clinician.

    Time frame: Baseline, 1 month, and 3 months after treatment initiation.
