AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults who have had a stroke on one side of the brain and have tight shoulder muscles that turn the arm inward.
- Age
- 18 years or older
- Sex
- All sexes can join.
- Disease stage
- One stroke affecting one side of the brain. Passive outward turning of the stiff shoulder is limited by more than 20 degrees. Modified Ashworth Scale score of 1 or higher for the inward-turning shoulder muscles. Stable medical condition and vital signs.
- Earlier treatment
- No shock wave treatment or botulinum toxin injection for post-stroke spasticity in the past three months.
Main reasons for not taking part
- Two or more strokes, brain injury, brain tumor or other brain disorders
- Other nervous system disorders or muscle and bone conditions that affect muscle tone testing
- Cancer, blood clotting disorders, local infection or a pacemaker
- Not clearly conscious or unable to follow instructions or take part in the tests due to thinking or language problems

Effects of Extracorporeal Shock Wave Therapy on Shoulder Internal Rotator Spasticity in Post-Stroke Patients: A Randomized Controlled Trial
Extracorporeal shock wave therapy (ESWT) has shown potential in reducing post-stroke limb spasticity. This study aims to evaluate the efficacy of focused ESWT on shoulder internal rotator spasticity in post-stroke patients.
Inclusion: Patients aged 18 years or older with unilateral cerebral stroke; Restricted passive external rotation of the spastic shoulder by more than 20 degrees; A Modified Ashworth Scale score of 1 or higher for shoulder internal rotator spasticity; Stable medical condition and vital signs; Clear consciousness, able to follow instructions.
Exclusion: Prior shock wave intervention or botulinum toxin injection for post-stroke spasticity within the past three months; History of two or more strokes, traumatic brain injury, brain tumors, or other cerebral disorders; Coexisting central nervous system disorders (e.g., spinal cord injury, Parkinson's disease) or other musculoskeletal conditions affecting muscle tone assessment; Ineligibility for shock wave intervention due to malignancies, coagulation disorders, localized infections, or presence of a pacemaker; Inability to participate in interventions or functional assessments due to cognitive, consciousness, or language impairments.
