Actual date on which the first participant was enrolled.

This clinical trial is exploring a treatment called repetitive peripheral magnetic stimulation (rPMS) to see if it can help people who have had a stroke and are experiencing shoulder subluxation, which is when the shoulder partially dislocates. The study is focusing on patients in the subacute phase of stroke recovery, which is an important time for rehabilitation. The researchers want to find out if this treatment can help reduce shoulder subluxation and improve movement and strength in the affected arm, potentially leading to better recovery outcomes for stroke survivors. In this study, participants will receive either the real rPMS treatment or a sham (fake) version for comparison. Each session lasts for 20 minutes and takes place five days a week over two weeks. Alongside this, participants will also undergo a standard rehabilitation program. The effectiveness of the treatment is being assessed through follow-up visits at 2, 4, 8, and 12 weeks after starting treatment. This will help researchers measure improvements in shoulder stability and arm function over time.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

20 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Criteria

Any sex

Biological sex of participants that are eligible to enroll.

From 18 to 80 Years

Range of ages for which participants are eligible to join.

Healthy volunteers not allowed

If individuals who are healthy and do not have the condition being studied can participate.

Criteria

5 inclusion criteria required to participate

Subacute phase (seven days to six months) and first time of stroke patients

Shoulder subluxation that measured half of a fingerbreadth or more

Meet the criteria for admission to a comprehensive rehabilitation program

Medically stable

Show More Criteria

5 exclusion criteria prevent from participating

Patients with contraindication for magnetic stimulation; cardiac pacemakers, magnetic materials near the intended stimulation site

Patients with pregnancy

Patients with severe aphasia or severe cognitive impairment

Patients with previous shoulder pathology or limit shoulder function before stroke

Treatment Groups

Study Objectives

2 intervention groups are designated in this study

50% chance of being blinded to the placebo group

Treatment Groups

Group I

Experimental

Real rPMS was applied to supraspinatus and posterior deltoid muscles for 20 Hz total 2,400 pulses.

Group II

Sham

sham rPMS was applied to supraspinatus and posterior deltoid muscles with the same coil as real rPMS, but in a position perpendicular to the skin, using intensity for 5% of the maximum output.
