- Conditions
- StrokeUpper Extremity Paresis
- Registration Number
- NCT06752499
- Lead Sponsor
- Ruijin Hospital
- Brief Summary
The goal of this clinical trials is to investigate the effectiveness of individualized online repetitive transcranial magnetic stimulation (rTMS) in enhancing upper limb motor rehabilitation during the subacute and chronic phase of stroke. It will also learn about the safety of individualized online rTMS intervention methods. The main questions it aims to answer are:
1. Does rTMS synchronized with motor training improve motor rehabilitation in patients with the ability to induce motor evoked potentials(MEPs)？
2. Dose individualized rTMS synchronized with motor training improve motor rehabilitation in patients without the ability to induce MEPs?
Researchers will compare online rTMS to offline and sham stimulation in patients with MEPs to see if online rTMS works to alleviate motor dysfunction in preliminary trials. And compare individualized online rTMS to non-individualized online rTMS and sham in patients without MEPs to see if individualized online rTMS works to alleviate motor dysfunction in Randomized, double-blinded, and controlled trials.
Participants will:
1. randomized to one group acoording to the MEP condition of each person;
2. receive rTMS treatment for 10 days, with 5 working days per week for a total of two weeks;
3. receive magnetic resonance imaging (MRI) and electroencephalogram (EEG) evaluations before and after the entire treatment;
4. conduct scales and MEP assessment one day before the treatment, as well as one day, one month, and three months after the treatment.
- Detailed Description
In preliminary experiment, patients were be randomly assigned to three groups: online, offline and sham groups. if patients were able to induce MEPs, intensity of TMS will be 80% RMT; if not , inensity of TMS will be 70%\~80% of TMS output.
In RCT, patients without MEPs were randomly assigned to three groups: individualized, non-individualized, and sham groups. Patients were stimulated over 2 week period, 4 sessions of tasks were performed everyday. The patient will undergo a 2-week (10-day) stimulation protocol, with fourty tasks performed daily. This includes one session of 10 baseline tasks measurement and three sessions of 5 Hz rTMS synchronized with 10 motor tasks. rTMS will be applied to the ipsilesional motor cortex, delivering about 750 pulses per day, for a total of 7,500 pulses, at an intensity of 70\~80% of TMS output.

- Primary Outcome Measures
Name Time Method Fugl-Meyer Assessment - Upper Extremity (FMA-UE) Before intervention (Week 0); After intervention (Week 2); Follow-up 1 (one month after intervetnion); Follow-up 2 (three months after intervention) The Fugl-Meyer Assessment (FMA) is 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. It is applied clinically and in research to determine disease severity, describe motor recovery, and to plan and assess treatment.
The Fugl-Meyer Assessment - Upper Extremity (FMA-UE) is the upper limb motor domain includes items assessing movement, coordination, and reflex action of the shoulder, elbow, forearm, wrist, hand. It ranges from 0 (hemiplegia) to 66 points (normal motor performance).
- Secondary Outcome Measures
Name Time Method Action Research Arm Test (ARAT) Before intervention (Week 0); After intervention (Week 2); Follow-up 1 (one month after intervetnion); Follow-up 2 (three months after intervention) 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. The ARAT was originally described by Lyle in 1981 as a modified version of the Upper Extremity Function Test and was used to examine upper limb functional recovery post damage to the cortex.
Modified Barthel Index (MBI) Before intervention (Week 0); After intervention (Week 2); Follow-up 1 (one month after intervetnion); Follow-up 2 (three months after intervention) The Barthel Index for activities of daily living was introduced in 1965 by Barthel and Mahoney to be used in the assessment of the degree of assistance required by patients with stroke (other neuromuscular or musculoskeletal disorders or oncology patients) with regards to 10 items of mobility and self-care (ADL).
The Pittsburgh Sleep Quality Index (PSQI) Before intervention (Week 0); After intervention (Week 2); Follow-up 1 (one month after intervetnion); Follow-up 2 (three months after intervention) The Pittsburgh Sleep Quality Index (PSQI) is a widely used self-report questionnaire that assesses sleep quality over a one-month time interval.
The PSQI is commonly used in both clinical and research settings to evaluate various aspects of sleep. It is a valuable tool for assessing sleep quality as it captures multiple dimensions of sleep, including both subjective experiences and objective parameters. It allows researchers and healthcare providers alike to obtain a comprehensive understanding of an individual's sleep patterns and disturbances and inform treatment decisions and interventions for sleep disorders.Motor Evoked Potential (MEP) - Resting Motor Threshold (RMT) Before intervention (Week 0); In the middle of intervention (Week 1); After intervention (Week 2); Follow-up 1 (one month after intervetnion); Follow-up 2 (three months after intervention) Resting motor threshold is an objective measure of cortical excitability. Numerous studies indicate that the success of motor recovery after stroke is significantly determined by the direction and extent of cortical excitability changes.
The average completion time for baseline tasks Before intervention (Week 0); Middle of intervention (Week 1); After intervention (Week 2) The average completion time for baseline tasks refers to the time (seconds) taken by the patient to complete the baseline motor task before each intervention.
