Summary

Transcranial direct current stimulation (tDCS) has shown promising results in the modulation of cortical excitability and the promotion of neuronal plasticity after stroke. The purpose of this study was to compare the effectiveness of three different montages of tDCS (anodal, cathodal and bilateral) in reducing the risk of falls and recovery of lower limb function in acute stroke patients.

Detailed description

This is a randomized sham-controlled trial reported following the 2010 CONSORT guidelines. The subjects were randomly allocated into 1 of 4 groups in a double-blinded parallel study design. Each patient received 10 sessions (5 consecutive days for 2 weeks) of real or sham stimulation at 2 mA intensity and current density equivalent to 0.05 A/m2.

Conditions

• Stroke

Interventions

Type	Name	Description
DEVICE	Anodal transcranial direct current stimulation	The active electrode is placed on the affected hemisphere
DEVICE	Cathodal transcranial direct current stimulation	The active electrode is placed on the unaffected hemisphere
DEVICE	Bilateral transcranial direct current stimulation	The cathode and anode is positioned as active electrodes on the unaffected and affected hemisphere,respectively.
DEVICE	Sham transcranial direct current stimulation	Placebo stimulation, with emission current by only 30 seconds
