About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Healthy adults
  • Age range between 18 - 60 years old
  • Right-handed dominant identified by the Edinburg Handedness Inventory
  • No recent muscle injuries of both limbs for a past 6-months

Exclusion criteria

  • Consumed caffeine within 24 hours prior the experiment
  • History of neurological symptoms i.e. seizures, weakness, loss of sensation or unclear history of pass illness
  • Present of metal implantation, intracranial shunt, cochlear implantation or cardiac pacemakers
  • Present of opened wound or infectious wound around scalp

Treatment and study plan

Transcranial Direct Current Stimulation

Device

Dual/Cathodal/Anodal/Sham tDCS will be applied in 2 mA, 20 mins. All experiments will be performed in random order for each subject.

Primary outcomes

  1. Change from baseline muscle strength after tDCS

    Time frame: Baseline (Pretest) and 40 minutes ( posttest)

    Muscle strength will be measured in Newton by using a hand-held dynamometer.
