High-definition Transcranial Direct Current Stimulation for Facilitating Hand Function Recovery After Stroke

NCT03875677 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 25

Summary

Transcranial direct current stimulation (tDCS) had recently been shown having feasibility in modulating cortical excitability transiently during motor training in a noninvasive way. The findings support that tDCS and motor practice can positively promote post-stroke motor learning to improve upper-limb motor recovery after stroke. A randomized controlled trial will be conducted with three groups: HD-tDCS, conventional tDCS and sham HD-tDCS. A 10-session training will be provided to evaluate the effectiveness of transient modulation of cortical excitability through tDCS with clinical assessment scores.

Conditions

Interventions

DEVICE

HD-tDCS group

5 sintered Ag/AgCl ring electrodes will be used at a radius of \~5cm. The electrodes will be placed inside plastic electrode holders which will be filled with gel to have better contact with the scalp.

DEVICE

Conventional tDCS group

A pair of 25 cm2 rubber electrodes enclosed in saline-soaked sponges and affixed to the head with rubber bands.

DEVICE

Sham HD-tDCS group

A pair of 25 cm2 rubber electrodes enclosed in saline-soaked sponges and affixed to the head with rubber bands.
