Brief Summary

Shoulder pain after stroke is one of the most common complications of stroke. Underlying mechanisms of shoulder pain after stroke still completely is not clarified. Central sensitization and neuropathic pain mechanisms are thought to play a role in the etiology of pain. Research on repetitive transcranial magnetic stimulation therapy in the treatment of pain in which somatosensory sensitization mechanisms play a role is increasing day by day. There are studies showing that application of high-frequency rTMS to the primary motor cortex provides effective pain relieving in most of painful conditions. However, data in the literature regarding the application of high-frequency rTMS in shoulder pain after stroke are very limited. There is only one clinical study related to this. More studies are needed in this area.In our study, it was aimed to examine the effects of this treatment protocol applied on the effects of pain on daily activities, upper extremity disability, anxiety, depression, range of motion and neurophysiological parameters.

Detailed Description

Stroke is one of the most common causes of disability and death in the adult population. Many complications such as depression, shoulder pain, falls, urinary system infections can develop after stroke. These complications prevent stroke rehabilitation and delay functional recovery. Hemiplegic shoulder pain is also one of the most common complications after stroke. Many possible causes underlying its development have been described; It may develop due to many pathologies such as rotator cuff lesions, biceps tendinopathy, soft tissue disorders such as myofascial pain, glenohumeral subluxation, spasticity, changes in peripheral and central nervous system activity. Many options such as joint range of motion (ROM) exercises, electrical stimulation, analgesics, intra-articular injections of corticosteroids, botulinum toxin-A injections are used in the management of pain. However, current treatment options provide limited pain relief, which causes chronic pain in many patients. This suggests that post-stroke shoulder pain is not only due to simple nociceptive stimuli from the shoulder joint, but also includes nociceptive and neuropathic mechanisms related to both the peripheral and central nervous systems. In recent years, TMS studies have been conducted in many painful conditions, which are thought to have complex pain mechanisms in the pathogenesis, and its effectiveness has been reported.In our study, it was aimed to examine the effects of this treatment protocol applied on the effects of pain on daily activities, upper extremity disability, anxiety, depression, range of motion and neurophysiological parameters.

• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: DOUBLE

Study Groups

Active stimulation group

Patients in the real stimulation group will receive rTMS treatment to the motor cortex (M1) of the affected hemisphere at a frequency of 5 Hz, once a day for 3 weeks and a total of 15 sessions. The application will be performed with Neurosoft-Neuro MS / D device. Before each session, the patient's resting motor threshold (RMT) value will be determined. RMT will be detected by obtaining a motor evoked potential of \>50 μV amplitude on electromyography recording of the contralateral first dorsal interosseous muscle in at least five out of 10 stimulations to the primary motor cortex.The stimulus intensity to be used in the treatment will be set as 90% of the motor threshold for the affected motor cortex and 100% of the motor threshold for the unaffected motor cortex.One session of stimulation will last for a total of 20 minutes and a total of 1000 pulses in the form of 5 Hz stimulation.

Group Type: EXPERIMENTAL

Repetitive transcranial magnetic stimulation

Intervention Type: DEVICE

Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive intervention that uses magnetic fields to stimulate nerve cells to improve the symptoms of a variety of disorders. In recent years, TMS studies have been conducted in many painful conditions, which are thought to have complex pain mechanisms in the pathogenesis, and its effectiveness has been reported.

Sham stimulation group

Fifteen sessions of sham repetitive transcranial magnetic stimulation (rTMS) treatment will be applied to the lesional primary motor cortex. The application will be performed with Neurosoft-Neuro MS / D device. The probe of the device will be held perpendicular to the motor cortex and operated from the lowest operating power of 1, so that the device makes the same sounds as the active application.
