Efficacy of Repetitive Peripheral Magnetic Stimulation on Shoulder Subluxation in Subacute Stroke Patients

The goal of this clinical trial is to study the efficacy of repetitive peripheral magnetic stimulation (rPMS) on shoulder subluxation in subacute stroke patients. The main questions it aims to answer are Could rPMS reduce shoulder subluxation and improve upper-limb motor recovery in subacute stroke patients?

Researchers will compare real rPMS to sham rPMS to see if rPMS works to improve shoulder subluxation and upper-limb motor recovery in subacute stroke patients.

Participants will:

  • Get real rPMS or sham rPMS for 20 minutes, 5 days a week for 2 weeks
  • Get conventional rehabilitation program 5 days a week for 2 weeks
  • Follow-up at 2-, 4-, 8- and 12-weeks after first day of treatment

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: real rPMS
Active rPMS administered for 10 sessions over a 2-week period (5 sessions per week)
Device: Peripheral magnetic stimulator
Repetitive Peripheral Magnetic Stimulation (rPMS) applied to the supraspinatus and posterior deltoid muscles. Parameters include a frequency of 20 Hz, with a total of 2,400 pulses per session.
Other Names:
  • PMS
Device: Peripheral magnetic stimulator
Repetitive Peripheral Magnetic Stimulation (rPMS) applied to the supraspinatus and posterior deltoid muscles. The stimulation coil is placed in a perpendicular position to the skin surface, utilizing a stimulation intensity set at 5% of the maximum stimulator output.
Other Names:
  • PMS
Sham Comparator: sham rPMS
Sham rPMS administered for 10 sessions over a 2-week period (5 sessions per week).
Device: Peripheral magnetic stimulator
Repetitive Peripheral Magnetic Stimulation (rPMS) applied to the supraspinatus and posterior deltoid muscles. Parameters include a frequency of 20 Hz, with a total of 2,400 pulses per session.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Acromiohumeral interval
Time Frame: pretreatment, 2-, 4-, 8- and 12-weeks after first day of treatment
the shortest distance between two parallel lines drawn from the inferior border of the acromion and the superior border of the humerus head on the anteroposterior shoulder x-ray
pretreatment, 2-, 4-, 8- and 12-weeks after first day of treatment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Fugl-Meyer assessment of upper extremities (FMA-UE)
Time Frame: pretreatment, 2-, 4-, 8- and 12-weeks after first day of treatment
a stroke-specific, performance-based impairment index. It is designed to assess motor functioning, balance, sensation and joint functioning in patients with post-stroke hemiplegia. Maximum score for upper extremity is 66 points.
pretreatment, 2-, 4-, 8- and 12-weeks after first day of treatment
Modified Ashworth Scale (MAS)
Time Frame: pretreatment, 2-, 4-, 8- and 12-weeks after first day of treatment
a grade of spasticity from a 0-4 ordinal scale. The grade is assigned by moving a joint/muscle through a high velocity quick stretch.
pretreatment, 2-, 4-, 8- and 12-weeks after first day of treatment
Numeric Pain Rating Scale (NRS)
Time Frame: pretreatment, 2-, 4-, 8- and 12-weeks after first day of treatment
Measuring of pain intensity, respondents are asked to choose the single number that best represents their pain intensity, on a 0 (No Pain) to 10 (Worst pain) scale.
pretreatment, 2-, 4-, 8- and 12-weeks after first day of treatment
