简要总结
To investigate the effects of different montages of tDCS on muscle strength in healthy adults
详细描述
Electrode montage or placement of tDCS over primary motor cortex can be categorized into unilateral (anodal or cathodal electrode over primary motor area) and bilateral tDCS (both anodal and cathodal electrode over the cortex). Previous studies reported benefits of different tDCS montages on muscle performance in healthy participants. However, there is no guideline for tDCS montages. This study aims to investigate immediate effects of different tDCS montages on muscle strength in healthy participants.

研究组 & 干预措施
Anodal-tDCS
Anodal transcranial direct current stimulation (tDCS) will be applied for 20 mins. Anode on the primary motor area (M1) of dominant hemisphere and Cathode on the supraorbital area of non-dominant hemisphere. Current intensity is fixed at 2 mA and current will flow continuously. The scope of intervention is to investigate effect of tDCS on muscle strength.
干预措施: Transcranial direct current stimulation (Device)
Cathodal-tDCS
Cathodal transcranial direct current stimulation (tDCS) will be applied for 20 mins. Cathode on the primary motor area (M1) of non-dominant hemisphere and Anode on the supraorbital area of dominant hemisphere. Current intensity is fixed at 2 mA and current will flow continuously. The scope of intervention is to investigate effect of tDCS on muscle strength.
干预措施: Transcranial direct current stimulation (Device)
Dual-tDCS
Dual transcranial direct current stimulation (tDCS) will be applied for 20 mins. Anode on the primary motor area (M1) of dominant hemisphere and Cathode on the primary motor area of non-dominant hemisphere. Current intensity is fixed at 2 mA and current will flow continuously. The scope of intervention is to investigate effect of tDCS on muscle strength.
干预措施: Transcranial direct current stimulation (Device)
Sham-tDCS
Dual transcranial direct current stimulation (tDCS) will be applied over C3-C4 or the motor area (M1) for 20 mins. Anode on dominant hemisphere, Cathode on non-dominant hemisphere. The scope of intervention is to investigate effect of tDCS on muscle strength.
干预措施: Transcranial direct current stimulation (Device)
