This pilot study aims to assess the effectiveness and safety of rTMS in the treatment of movement disorders in patients with ICH.
While the fatality rate of intracerebral hemorrhage (ICH) has decreased, many patients continue to experience persistent limb movement dysfunction. Motor dysfunction in ICH is commonly attributed to basal ganglia hemorrhage, as the basal ganglia play a central role in the extrapyramidal motor system. Therefore, promoting the remodeling of the extrapyramidal motor system holds great significance for effectively treating ICH patients with movement disorders.
Repetitive transcranial magnetic stimulation (rTMS) is a safe and non-invasive neuromodulation technique that can modulate neuronal activity, influence neuronal synaptic plasticity, and enhance brain function. Currently, rTMS has shown promise in improving motor function among patients with stroke and those who have undergone brain tumor surgery, which provides valuable insights for its potential application in patients with motor dysfunction following ICH surgery.
This pilot study aims to evaluate the efficacy and safety of rTMS in the treatment of ICH patients with movement disorders. The participants will be randomly assigned to either a real rTMS treatment group or a sham group. The study will assess and compare various clinical outcomes, including the FMA (Fugl-Meyer Assessment), NIHSS (National Institutes of Health Stroke Scale), and BI (Barthel Index) scores, over a period of 6 months.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| rTMS intervention group | Experimental | Participants will undergo rTMS treatment using the Magstim Rapid 2 magnetic stimulation device. The coil was placed positioned tangentially on the scalp, targeting the hot spot (thumb movement area) in the ipsilateral cerebral hemisphere. The stimulation protocol will involve 10-Hz stimulation for 2 seconds, followed by a followed by a 10-second rest, which was repeated 50 times. Patients will receive treatment once a day, five days a week (Monday to Friday), for a total of two consecutive weeks. |
|
| Sham group | Sham Comparator | Patients in the sham group underwent sham stimulation using the Magstim Rapid 2 magnetic stimulation device with the same protocol. The coil was positioned to target the same hot spot, with an angulation parallel to the gyrus to the gyrus in order to additionally minimize the rTMS effect. |

| rTMS with Magstim Rapid 2 magnetic stimulation device | Device | The study will involve the utilization of the Magstim Rapid 2 magnetic stimulation device to administer rTMS treatment to the participants. The coil will be positioned tangentially on the scalp, specifically targeting the hot spot (thumb movement area) in the ipsilateral cerebral hemisphere. During the stimulation protocol, a 10-Hz stimulation will be applied for 2 seconds, followed by a 10-second rest period. This cycle will be repeated 50 times. The treatment will be administered once daily, from Monday to Friday, for a continuous period of two weeks. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Fugl-Meyer Assessment (FMA) | Motor function was evaluated using the FMA, a scale ranging from 0 to 100 that measures movement ability. Higher scores reflect better motor function. The outcome measure assesses the change in the FMA score at 6 months compared to baseline. | Month 6 |

| Changes in the structural brain network connectivity | Using Diffusion Tensor Imaging (DTI) to assess the connectivity of the brain structural network, DTI reveals the connectivity by measuring the diffusion direction and rate of water molecules in the tissue. Based on DTI, the changes in the connectivity of the brain structural network are compared between 6 months after treatment and the baseline level. |

| Fugl-Meyer Assessment (FMA) Response |
Motor function was assessed using the FMA, which utilizes a scale ranging from 0 to 100. Higher scores indicate improved movement function, and an increase of 10 or more points in the FMA is considered a significant improvement. The response rate of the FMA was calculated at 1 day, 1 month, 3 months, and 6 months following therapy. |

| Change in Fugl-Meyer Assessment, Upper Limb (FMA-UL) | Motor function of upper limb was evaluated using the FMA-UL, a scale ranging from 0 to 66 that measures upper limb movement ability. Higher score reflect better motor function. The outcome measure assesses the change in the FMA-UL score at 1 day, 1month, 3 months, and 6 months compared to baseline. | Day 1, Month 1, Month 3, Month 6 |
