组别:

左DLPFC组

样本量:

Group:

left DLPFC group

Sample size:

干预措施:

TMS干预采用iTBS刺激方案,刺激靶点为左额叶背外侧区(DLPFC),其体表投影区为EEG 10-20标准的F5电极位置,使用8字形线圈与左半球F5电极位置的头皮成切向放置,刺激强度为90%运动诱发电位阈值强度(rMT)。每次干预由20个刺激序列组成,每个序列包含3个频率为50Hz的脉冲(每200ms重复一次,持续2秒,共10簇30个脉冲),序列间隔8秒,每个刺激序列共600个刺激脉冲,持续190s。每次刺激2序列,间隔15分钟,每周刺激5天,共刺激2周。 同时接受常规的物理治疗和作业治疗。

干预措施代码:

Intervention:

The TMS intervention employed an intermittent theta-burst stimulation (iTBS) protocol. The stimulation target was the left dorsolateral prefrontal cortex (DLPFC), with its scalp projection corresponding to the F5 electrode position of the international 10–20 EEG system. A figure-of-eight coil was placed tangentially to the scalp over the left F5 location. Stimulation intensity was set at 90% of the resting motor threshold (rMT). Each treatment session consisted of two stimulation blocks separated by a 15-minute interval. Each block comprised 20 trains; each train consisted of 10 bursts of three pulses at 50 Hz (repeated every 200 ms for 2 s, resulting in 10 bursts and 30 pulses per train). The inter-train interval was 8 s, yielding a total of 600 pulses per block over a duration of 190 s. Stimulation was delivered 5 days per week for 2 consecutive weeks. Concurrently, participants received conventional physical therapy and occupational therapy.

右PPC组

样本量:

Group:

right PPC group

Sample size:

干预措施:

TMS刺激靶点为患侧右顶叶后皮层(PPC)区域,具体为EEG 10-20标准的P4点。刺激强度为90%运动诱发电位阈值强度,频率为5Hz,连续刺激10脉冲,间歇2秒,重复1200次,共1200个脉冲,每天刺激1次,每周刺激5天,共刺激2周。 同时接受常规的物理治疗和作业治疗。

干预措施代码:

Intervention:

The stimulation target was the right posterior parietal cortex (PPC) of the affected hemisphere, localized at the P4 electrode position of the 10–20 EEG system. High-frequency repetitive transcranial magnetic stimulation (rTMS) was applied at 5 Hz with an intensity of 90% rMT. Each train consisted of 10 consecutive pulses, followed by a 2-second inter-train interval. The trains were repeated 120 times, yielding a total of 1200 pulses per session. Stimulation was administered once daily, 5 days per week, for 2 weeks. Concurrently, participants received conventional physical therapy and occupational therapy.

Intervention code:

组别:

假刺激组

样本量:

16

Group:

sham stimulation group

Sample size:

干预措施:

假刺激组的TMS干预采用与真实iTBS组相同的设备、刺激部位、治疗频率和时长,但改为假刺激线圈,与真实刺激相同的咔嗒声和头皮触感,但不会向深层神经组织传递有效脉冲。 同时接受常规的物理治疗和作业治疗。

干预措施代码:

Intervention:

The sham group used the same device, stimulation site, treatment frequency, and session duration as the active iTBS group, but was equipped with a sham coil. The sham coil produced identical clicking sounds and scalp sensations without delivering effective electromagnetic pulses to deep neural tissue. Concurrently, participants received conventional physical therapy and occupational therapy.

随机方法(请说明由何人用什么方法产生随机序列):

将符合右侧脑卒中引起USN症状的患者按照1:1:1的比例随机分配到A组:左DLPFC组;B组:右PPC组;C组:假刺激组。用SPSS 27.0软件的随机函数产生随机顺序,该随机数字由专人保管分组,保管人员不参与本研究的其他任何环节。

Randomization Procedure (please state who generates the random number sequence and by what method):

Patients who met the criteria for unilateral spatial neglect (USN) caused by right-hemisphere stroke were randomly assigned in a 1:1:1 ratio to Group A (left DLPFC group), Group B (right PPC group), and Group C (sham stimulation group). The randomization sequence was generated using the random function of SPSS 27.0 software and was securely maintained by a designated person responsible for group assignment, who was not involved in any other aspect of the study.

公开/Public

盲法:

对受试者(单侧忽略患者)设盲,假刺激与真刺激的线圈外形完全一致,并采用相同的刺激参数,产生类似的声音和头皮触感,但不产生有效刺激。对受试者进行前后评估的人员不参与患者的干预,也不了解单侧忽略患者的分组。

Blinding:

The subjects (patients with unilateral neglect) were blinded. The sham stimulation coil was identical in appearance to the real stimulation coil and used the same stimulation parameters, producing similar sounds and scalp sensations without delivering effective stimulation. The personnel who performed the pre- and post-intervention assessments were not involved in the patients' intervention and were blinded to the group assignment of the patients with unilateral neglect.
