This Study is About the Efficacy of Repetitive Peripheral Magnetic Stimulation on the Treatment of 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

  • Patients with unstable vital signs

Treatment and study plan

Peripheral magnetic stimulator

Device

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

Primary outcomes

  1. 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

Secondary outcomes

  1. 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.

  2. 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.

  3. 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.
