About this study

The study compares two different shockwave treatment doses, each delivered as a single session to patients with adhesive capsulitis of the shoulder. We will measure shoulder range of motion before and after treatment and assess functional improvement using the Constant-Murley score. Finally, we will analyze changes in joint mobility at various post-treatment time intervals to evaluate the therapeutic effectiveness of the two shockwave dosing protocols.

  • active abduction in the scapular plane ≤ 135°

  • coagulopathy
  • inability to complete follow-up assessments

Treatment and study plan

focused extracoporeal sockwave

Device

Focused ESWT energy was initiated at level 5 (0.034 mJ/mm²) with a 4-Hz frequency and subsequently adjusted based on patient tolerance. After the application of coupling gel, different pulses were applied one fingerbreadth inferior to the anterior acromion, lateral to the acromion, and posterior to the acromion.

Primary outcomes

  1. We assessed changes in shoulder range of motion using a standard goniometer before and after treatment with varying shockwave dosages

    Time frame: Before treatment, immediately after treatment, and at 1, 2, 4, 8, and 12 weeks post-treatment

    In patients receiving different doses of extracorporeal shockwave therapy for adhesive capsulitis, we assessed changes in shoulder range of motion before and after treatment using a standard goniometer. We will assess forward flexion, abduction, external rotation, and internal rotation. The better the range of motion, the better the treatment outcome.

Secondary outcomes

  1. We assessed changes in shoulder functional outcomes using the Constant-Murley questionnaire before and after treatment with varying shockwave dosages

    Time frame: before treatment and 12 weeks posttreatment

    In patients receiving different doses of extracorporeal shockwave therapy for adhesive capsulitis, we evaluated changes in shoulder function by administering the Constant-Murley questionnaire both before and after treatment. The questionnaire includes four subcategories: pain score (maximum 15 points), activities of daily living (maximum 20 points), movement (maximum 40 points), and strength (maximum 25 points). The Constant-Murley Score has a maximum of 100 points, with higher scores indicating a better outcome."

  2. The impact of changes over time before and after shockwave therapy on joint angle improvement

    Time frame: immediately after treatment and 1, 2, 4, 8, and 12 weeks posttreatment

    We analyzed the magnitude of joint angle changes at multiple time points to compare the therapeutic effects of the various shockwaves doses.
