Shockwave and cold combo may ease stroke shoulder pain
NCT ID NCT07196267
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether combining two physical therapies—extracorporeal shockwave therapy and cryoflow (cold) therapy—can reduce shoulder pain and spasticity in stroke survivors with rotator cuff tendonitis. Thirty participants received either one therapy alone or both together over 8 weeks. Researchers measured pain, range of motion, and muscle tone to see which approach works best.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Extracorporeal Shockwave Therapy and Cryoflow Therapy
- What this could lead to
- If it works, this could offer a non-drug way to reduce shoulder pain and spasticity, helping stroke survivors move better and regain arm function.
- What could go wrong
- This is a small, early study with only 30 participants, so results may not apply to everyone. The therapies may not work better than existing treatments.

Inclusion Criteria: * Diagnosis of stroke confirmed by neurologist via physical examination and MRI. Age between 50 and 70 years. Moderate to severe shoulder spasticity, graded as Stage 3 on the Modified Ashworth Scale (MAS) for shoulder adductors. Medically stable (vital signs within normal limits). Conscious, cooperative, and able to follow instructions. No orthopedic conditions, surgeries, or injuries affecting the shoulder or upper limb. No sensory impairments (visual, auditory, proprioceptive) that would interfere with assessment or treatment. Able to provide informed consent. Exclusion Criteria: * History of shoulder surgery or fracture. Presence of shoulder subluxation or dislocation. Severe cognitive impairment or inability to communicate. Uncontrolled hypertension, cardiac disease, or other unstable medical conditions. Skin lesions, open wounds, or infection over the shoulder region. Diagnosis of frozen shoulder (adhesive capsulitis), rheumatoid arthritis, or other inflammatory joint diseases. Previous treatment with ESWT or cryotherapy for shoulder within the last 6 months. Use of botulinum toxin injections in the upper limb within the last 3 months
