Effectiveness of High-intensity Peripheral Magnetic Stimulation on Hemiplegic Shoulder Pain After Stroke

30 oktober 2026 bijgewerkt door: Tuğba Atan, MD, Gaziler Physical Medicine and Rehabilitation Education and Research Hospital

Effectiveness of High-intensity Peripheral Magnetic Mtimulation in Patients With Post-stroke Hemiplegic Shoulder Pain

This study aims to investigate the effectiveness of high-intensity electromagnetic stimulation using the BTL-6000 Super Inductive System (SIS) in the management of hemiplegic shoulder pain in patients with stroke. Hemiplegic shoulder pain is a common complication following stroke and may negatively affect upper limb function, participation in rehabilitation, and quality of life. The study will evaluate whether treatment with the Super Inductive System can reduce shoulder pain and improve shoulder-related clinical outcomes. The findings are expected to contribute to the evidence regarding non-invasive physical therapy approaches for hemiplegic shoulder pain.

Wapens en interventies

Deelnemersgroep / Arm
Interventie / Behandeling
Experimenteel: Active Peripheral Magnetic Stimulation

Participants assigned to this group will receive active peripheral magnetic stimulation according to the predefined treatment protocol. The intervention will be administered using the study device under the supervision of trained healthcare professionals.
Apparaat: Active Peripheral Magnetic Stimulation

Participants in the active intervention group will receive active peripheral magnetic stimulation for hemiplegic shoulder pain following stroke. Treatment will be administered using the study device by trained healthcare professionals according to the predefined treatment protocol.
Sham-vergelijker: Sham Peripheral Magnetic Stimulation

Participants assigned to this group will receive sham peripheral magnetic stimulation using a procedure designed to mimic the active intervention without delivering the intended therapeutic magnetic stimulation. The intervention schedule and assessment procedures will be consistent with those of the active stimulation group.
Apparaat: Sham Peripheral Magnetic Stimulation

Participants in the sham comparator group will receive sham peripheral magnetic stimulation for hemiplegic shoulder pain following stroke. The sham procedure will be designed to mimic the active intervention without delivering therapeutic magnetic stimulation. The treatment schedule and assessment procedures will be consistent with those of the active stimulation group.

Wat meet het onderzoek?

Primaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Visual Analog Scale (VAS) for Shoulder Pain
Tijdsspanne: Baseline and immediately after completion of 10 treatment sessions (approximately 4 weeks)

Shoulder pain will be assessed using the Visual Analog Scale (VAS). Patients will be asked to rate their average shoulder pain experienced at rest and during shoulder movements over the previous 24 hours on a scale from 0 (no pain) to 10 (unbearable pain).
Baseline and immediately after completion of 10 treatment sessions (approximately 4 weeks)

Secundaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Goniometric Measurement of Shoulder Range of Motion
Tijdsspanne: Baseline and immediately after completion of 10 treatment sessions (approximately 4 weeks)

Passive range of motion of the affected shoulder will be measured using a goniometer. Flexion, abduction, internal rotation, and external rotation will be recorded in degrees.
Baseline and immediately after completion of 10 treatment sessions (approximately 4 weeks)
Shoulder Pain and Disability Index (SPADI)
Tijdsspanne: Baseline and immediately after completion of 10 treatment sessions (approximately 4 weeks)

Shoulder pain and functional limitations will be assessed using the Shoulder Pain and Disability Index (SPADI). The scale consists of 13 items covering pain (5 items) and disability (8 items). Scores range from 0 to 100, with higher scores indicating greater pain and disability.
Baseline and immediately after completion of 10 treatment sessions (approximately 4 weeks)
Functional Independence Measure (FIM)
Tijdsspanne: Baseline and immediately after completion of 10 treatment sessions (approximately 4 weeks)

Functional independence will be assessed using the Functional Independence Measure (FIM). The scale consists of 18 items evaluating self-care, transfers, locomotion, sphincter control, communication, and social cognition. Each item is scored from 1 (total dependence) to 7 (complete independence). Total scores range from 18 to 126, with higher scores indicating greater functional independence.
Baseline and immediately after completion of 10 treatment sessions (approximately 4 weeks)
Fugl-Meyer Assessment - Upper Extremity Motor Subscale (FMA-UE)
Tijdsspanne: Baseline and immediately after completion of 10 treatment sessions (approximately 4 weeks)

Upper extremity motor function will be assessed using the Fugl-Meyer Assessment Upper Extremity Motor Subscale (FMA-UE), which evaluates motor function, coordination, and reflex activity in the affected upper extremity. The motor subscale ranges from 0 to 66 points, with higher scores indicating better motor function.
Baseline and immediately after completion of 10 treatment sessions (approximately 4 weeks)
Modified Ashworth Scale (MAS) for Shoulder Spasticity
Tijdsspanne: Baseline and immediately after completion of 10 treatment sessions (approximately 4 weeks)

Shoulder spasticity will be assessed using the Modified Ashworth Scale (MAS), focusing on shoulder adduction and internal rotation patterns rather than individual muscle isolation. The functional contributions of the subscapularis, pectoralis major, latissimus dorsi, and teres major muscles will be considered. Assessments will be performed with patients in a seated position, with the scapula stabilized. Standardized rapid passive movements will be applied, and resistance to movement will be graded according to MAS criteria (0, 1, 1+, 2, 3, and 4), with higher grades indicating greater muscle tone.
Baseline and immediately after completion of 10 treatment sessions (approximately 4 weeks)
Shoulder Ultrasonographic Findings
Tijdsspanne: Baseline and immediately after completion of 10 treatment sessions (approximately 4 weeks)

Shoulder ultrasonography will be performed using a 5-12 MHz linear transducer. The acromioclavicular joint, glenohumeral joint, long head of the biceps tendon, rotator cuff tendons (supraspinatus, infraspinatus, and subscapularis), and subacromial-subdeltoid bursa will be evaluated. Acromioclavicular joint abnormalities, glenohumeral subluxation, biceps tendon pathology, bursitis, and rotator cuff tendinopathy will be recorded as present or absent. In patients with partial-thickness rotator cuff tears, the maximum anteroposterior tear diameter will be measured in millimeters. Patients with full-thickness rotator cuff tears will be excluded.
