The Effects of Different Montages of tDCS on Muscle Strength in Healthy Adults
June 19, 2022 updated by: Mahidol University
The Effects of Different Montages of Transcranial Direct Current Stimulation on Muscle Strength in Healthy Adults
To investigate the effects of different montages of tDCS on muscle strength in healthy adults
Study Overview
Status
Completed
Conditions
Intervention / Treatment
Detailed Description
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: 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.
|
Dual/Cathodal/Anodal/Sham tDCS will be applied in 2 mA, 20 mins.
All experiments will be performed in random order for each subject.
|
Experimental: 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.
