Effect of Therapeutic Ultrasound Combined With Exercise on Subacromial Impingement Syndrome
30 juni 2026 bijgewerkt door: Raquel A. Casarotto, University of Sao Paulo General Hospital
Effects of Therapeutic Ultrasound Combined With Exercise in the Rehabilitation of Individuals Diagnosed With Subacromial Impingement Pain Syndrome: a Randomized, Controlled, Double-blind Clinical Trial.
The aim of this study is to analyze the effects of Therapeutic Ultrasound combined with a Therapeutic Exercises program on pain reduction and improvement of function, range of motion (ROM), and functionality in individuals with Subacromial Impingement Syndrome. The main questions it aims to answer are:
Can the application of therapeutic ultrasound combined with exercise reduce pain and improve the ability to perform daily activities (functionality) in patients with Subacromial Impingement Syndrome? Does combining therapeutic ultrasound with exercise improve pain and functionality in patients with Subacromial Impingement Syndrome more effectively than using exercise alone to treat this syndrome? Researchers compared the application of therapeutic ultrasound combined with therapeutic exercises with placebo ultrasound (equipment programmed similarly to active ultrasound but emitting ultrasound waves) plus therapeutic exercises to determine if adding active ultrasound to the treatment is more effective than performing exercises alone in treating patients with Subacromial Impingement Syndrome.
Patients should be evaluated before the start of treatment, eight weeks after the start of treatment, and six months after the end of treatment.
Patients will receive therapeutic ultrasound or placebo combined with exercise 3 times a week for 8 weeks.

Gedetailleerde beschrijving
Introduction: Subacromial impingement syndrome (SIS)/Subacromial pain syndrome (SPS) is among the most common causes of pain and reduced shoulder functionality, characterized by repetitive impingement of structures located in the subacromial space, which anatomically comprises, superiorly, the acromion and inferiorly, the shoulder joint capsule and the subacromial bursa.
Management of pathology includes numerous interventions, depending on the intensity of the pain and anatomopathological classification, involving conservative treatment (medications and physiotherapy) or surgical treatment in more severe cases.
Objective: To verify the effects of therapeutic ultrasound (TUS), in continuous (USC) and pulsed (USP) modes, associated with a standardized therapeutic exercise (TE) program, on pain, range of motion, and functionality in individuals with shoulder pain associated with subacromial impingement syndrome (SIS).
Methods: A randomized, controlled, double-blind clinical trial was conducted with 120 participants of both sexes, aged 30 to 75 years, with a clinical and ultrasound diagnosis compatible with subacromial impingement syndrome/rotator cuff-related shoulder pain.
Participants were divided into four groups: (USC+TE), (USP+TE), placebo-controlled TUS associated with exercises (USPPL+TE), and isolated therapeutic exercises (TE)

Pain Intensity
Tijdsspanne: Baseline, Week 12, and Day 240.
|
Pain intensity was assessed using the Visual Analog Scale (VAS), separately for pain at rest and pain during activities of daily living (ADLs).
The VAS ranges from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain.
Higher scores indicate greater pain intensity.
|
Baseline, Week 12, and Day 240.

|
Shoulder pain and disability
Tijdsspanne: Baseline, Week 12, and Day 240.
|
Shoulder pain and disability were assessed using the Shoulder Pain and Disability Index (SPADI).
The questionnaire consists of 13 items distributed across two domains: pain, with five items, and disability/function, with eight items.
Each item is scored from 0 to 10.
The total score and domain scores are converted into a percentage scale ranging from 0 to 100, with higher scores indicating worse shoulder pain and disability.

Functional shoulder performance
Tijdsspanne: Baseline, Week 12, and Day 240.
|
Functional shoulder performance was assessed using the Modified University of California at Los Angeles Shoulder Rating Scale (Modified UCLA Shoulder Rating Scale).
The scale includes five domains: pain, function, active forward flexion range of motion, manual strength testing for forward flexion, and patient satisfaction.
The total score ranges from 0 to 35 points, with higher scores indicating better shoulder function.
