Eligibility Criteria
Inclusion Criteria:
- written consent
- hemiparetic patient after stroke in chronic phase (> 6 months)
- capacity to walk with or without technical assistance
- following rehabilitation program for lower limbs
Exclusion Criteria:
- patient with bilateral brain lesion, cerebellar syndrom, and apraxia and/or aphasia
- previous orthopedic surgery in paretic lower limb (<6 moths)
- usual tDCS contraindications
- pregnant woman

Outcomes
Primary Outcome Measures
maximum voluntary isometric strength of knee extensors
The maximum voluntary isometric strength of paretic knee extensors will be evaluated with a isokinetic dynamometer, which measure peak torque.
Secondary Outcome Measures
Resistive peak torque during passive knee flexion
Angle related to the resistive peak torque generation of the knee extensors
Amplitude of the interpolation twitch
EMG activation of the knee flexors and extensors during the strength evaluations (active and passive)
Functional evaluation of the gait performance and balance

5. Study Description
Brief Summary
Previous studies show that one session of tDCS allow to improve muscle strength in hemiparetic patients in anodal condition. We test a new electrods configuration : a anodale stimulation opposite to the cortical representation area of the injured hemisphere and a simultaneous stimulation opposite to the homonyme the cortical representation area of the healthy hemisphere. This approach seems to be the best relevant electrods configuration in order to restore the inter-hemispheric balance.
We hypothesis that one session of tDCS with this electrods configuration allow to improve paretic quadriceps strength in hemiparetic patients after stroke.
