Brief summary
The primary objective of this clinical study is to assess the comparative efficacy of individualized intermittent theta burst stimulation (iTBS) in contrast to standard iTBS for individuals post-stroke experiencing upper limb impairment. The key inquiries addressed in this study encompass: Enhancement of Upper Limb Function: The primary investigation seeks to determine whether individualized iTBS yields superior improvements in upper limb functionality compared to standard iTBS. Long-Term Effects: This study endeavors to explore the sustained effects of both individualized and standard iTBS on upper limb function over an extended duration. Neural Mechanisms Investigation: Functional near-infrared spectroscopy (fNIRS) will be employed to elucidate the neural mechanisms underlying the impact of iTBS on the enhancement of upper limb function. Post-stroke individuals with upper limb impairment will undergo pre-treatment assessments, including motor function evaluations and fNIRS tests. Subsequently, they will be randomized into three groups: individualized iTBS, standard iTBS, and sham stimulation. Participants will undergo post-treatment assessments and follow-up evaluations. The research team aims to discern disparities in the efficacy of different iTBS modalities. The central hypothesis posits that individualized iTBS will demonstrate superior efficacy in enhancing post-stroke upper limb function, with sustained effects persisting for a minimum of one month.
Detailed description
This research constitutes a single-center, double-blind, randomized controlled study. Upon enrollment, baseline information is established through the assessment of upper limb function using the Fugl Meyer Assessment (FMA), the modified Rankin Scale, the Action Research Arm Test (ARAT), and a handgrip test. Additionally, functional near-infrared spectroscopy (fNIRS) is employed to assess brain function, providing insights into the patient's motor network. Participants in the study are randomly assigned to one of three groups: individualized iTBS, standard iTBS, and sham stimulation. All participants undergo physical therapy and occupational therapy tailored to their functional evaluation. After three weeks of treatment, participants are required to complete the aforementioned assessments, with a follow-up evaluation scheduled one month post-treatment.
Interventions
DEVICEindividualized intermittent theta burst sitmulation (iTBS)
Participants undergo daily sessions of individualized intermittent theta-burst stimulation (iTBS) administered with the MagStim stimulator (Rapid2, MagStim, Whiteland, United States). The intervention spans five days a week and extends over a three-week period. In this group, participants receive a personalized iTBS protocol comprising three pulses of stimulation delivered at 50 Hz, repeated every 200 ms. The stimulation frequency is tailored based on the electroencephalogram (EEG) results and is administered every 10 seconds, with a total duration of 190 seconds. The treatment is administered once a day for five days a week and continues for three weeks, with an immediate cessation in case of any discomfort. This study design ensures a meticulous and tailored approach to iTBS administration.
DEVICEstandard iTBS
The MagStim stimulator (Rapid2, MagStim, Whiteland, United States) was employed in the current study. The intermittent theta-burst stimulation (iTBS) protocol utilized three pulses of stimulation delivered at a frequency of 50 Hz, with a repetition rate of every 200 ms. These pulses were organized into 2-second trains, repeated every 10 seconds, resulting in a cumulative duration of 190 seconds (equivalent to a total of 600 pulses). Notably, the administration of the treatment ceased promptly in the event of any participant discomfort.
DEVICEsham stimulation
The device and protocol are identical to the standard iTBS, with the only difference being the orientation of the coil, which is perpendicular to the scalp.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Fugl-Meyer Assessment-upper extremity | Befor and after the treatment, and 1 month after the treatment. | Fugl-Meyer Assessment (FMA) scale is an index to assess the sensorimotor impairment in individuals who have had stroke. The FMA motor assessments for the upper fucntion with maximum score 66 points, including relflex activity, flexor synergy, extensor synergy, movement combining synergies, movement out of synergy,normal reflex, wrist function, hand function and coordination/speed, and sensory assessment. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| modified Rankin Scale | Befor and after the treatment, and 1 month after the treatment. | The Modified Rankin Scale (mRS) assesses disability in patients who have suffered a stroke and is compared over time to check for recovery and degree of continued disability. A score of 0 is no disability, 5 is disability requiring constant care for all needs; 6 is death. |
| Action Research Arm Test | Befor and after the treatment, and 1 month after the treatment. | The Action Research Arm Test (ARAT) is a 19 item observational measure used by physical therapists and other health care professionals to assess upper extremity performance (coordination, dexterity and functioning) in stroke recovery, brain injury and multiple sclerosis populations.Items comprising the ARAT are categorized into four subscales (grasp, grip, pinch and gross movement) and arranged in order of decreasing difficulty, with the most difficult task examined first, followed by the least difficult task. Task performance is rated on a 4-point scale, ranging from 0 (no movement) to 3 (movement performed normally). |
| handrip test | Befor and after the treatment, and 1 month after the treatment. | Hand grip test will be finished with a dynamometer. |
| functional nearinfrared spectroscopy | Befor and after the treatment, and 1 month after the treatment. | The functional nearinfrared spectroscopy (fNIRS) is used to explore the motor network of the participants. |
