Brief Summary

Spasticity is one of the most common disorders in patients with central nervous system diseases such as stroke. Transcranial direct current stimulation stimulation (tDCS) is a noninvasive tool that can be used to modulate cortical excitability of the leg motor area, and the spinal motor circuits as well. Objective:The objectives of this study is to examine the efficacy of anodal tDCS combined with Biodex balance training on lower limbs spasticity in chronic stroke patients using laboratory and clinical assessments.

Study Arms (2)

Arm 1:tDCS

ACTIVE COMPARATOR

Transcranial direct current stimulation (tDCS) Participants underwent tDCS(2mA) brain stimulation (20 minutes) and simultaneous balance training(20 minutes) for 5 consecutive days

Device: Transcranial direct current stimulation (tDCS)

Arm 2: Sham tDCS

SHAM COMPARATOR

Sham tDCS and simultaneous balance training(20 minutes) for 5 consecutive days

Device: Sham tDCS

Interventions

Participants underwent tDCS(2mA) brain stimulation for 20 minutes plus balance training for 20 minutes for 5 consecutive days.

Arm 1:tDCS
Sham tDCSDEVICE

During sham stimulation, the current ramped up for 30 seconds, ramped back down for 30 seconds, and then remained off for the duration of the stimulation plus balance training for 20 minutes for 5 consecutive days.

Arm 2: Sham tDCS
