简要总结
Transcranial electrical stimulation (tCES) is contemporarily important issues in the advanced rehabilitation medicine. tCES can selectively change the excitability of regional cortex with non-invansive and safety properties. Therefore, the investigators aim to develop a set of tCES system with special waveforms for using in clinical rehabilitation of upper extremities. This developed tCES system is smaller than all commercial available products, which could be conveniently and portably wore on head for clinical rehabilitation. In addition, the present tCES system with special waveforms developing by the investigators is much more efficient on improving neuroplasticity than the traditional transcranial direct current stimulation (tDCS) in rats. The investigators hope the tCES system combined with the rehabilitation of body extremities will become a routine treatment for stroke patients at hospitals or residential rehabilitation in the future.
详细描述
Transcranial direct current stimulation (tDCS) and intermittent theta burst stimulation (iTBS) were both demonstrated to have therapeutic potentials to rapidly induce neuroplastic effects in various rehabilitation training regimens. Recently, the investigators have developed a novel transcranial electrostimulation device that can flexibly output an electrical current with combined tDCS and iTBS waveforms. However, limited studies have determined the therapeutic effects of this special waveform combination on clinical rehabilitation. Herein, the investigators aiming to brain stimulation effects of tDCS-iTBS on upper-limb motor function in chronic stroke patients.
Twenty-four subjects with a chronic stroke were randomly assigned to a real non-invasive brain stimulation (NIBS; subjects received the real tDCS+iTBS output) group or a sham NIBS (subjects received sham tDCS+iTBS output) group. All subjects underwent 1 h treatment of a conventional rehabilitation program (3 days a week for 6 weeks), where a 20-min NIBS intervention was simultaneously applied during conventional rehabilitation. Outcome measures were assessed before and immediately after the intervention period: Fugl-Meyer Assessment-Upper Extremity (FMA-UE), Jebsen-Taylor Hand Function Test (JTT), and Finger-to-Nose Test (FNT).

结局指标
主要结局
Change from baseline in the Fugl-Meyer Assessment upper extremity scale (FMA-UE) after intervention
时间窗: Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session)
The FMA-UE was performed (score ranges from 0 to 66) to assess upper limb motor recovery. Each movement is estimated by a 3-point scale (0-1-2). The total score of the FMA-UE is 66, and a higher score indicates that the patient has better movement ability.
次要结局
- Change from baseline in the Jebsen-Taylor Hand Function Test (JTT) after intervention(Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session))
- Change from baseline in the Finger to Nose Test after intervention(Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session))
- Modified Ashworth scale (MAS) measures(Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session))
