“…122,123 Moreover, the effect of tDCS on fine motor control of the paretic foot has been evaluated by applying anodal or sham tDCS in random order over the lower limb M1 of the lesioned or nonlesioned hemisphere. In each session, tDCS was associated with a motor task that consisted of tracking a sinusoidal waveform for 15 minutes using dorsiflexion-plantar flexion movements of their paretic ankle.…”

Walking rehabilitation is one of the primary goals in stroke survivors because of its great potential for recovery and its functional relevance in daily living activities. Although 70% to 80% of people in the chronic poststroke phases are able to walk, impairment of gait often persists, involving speed, endurance, and stability. Walking involves several brain regions, such as the sensorimotor cortex, supplementary motor area, cerebellum, and brainstem, which are approachable by the application of noninvasive brain stimulation (NIBS). NIBS techniques, such as repetitive transcranial magnetic stimulation and transcranial direct current stimulation, have been reported to modulate neural activity beyond the period of stimulation, facilitating neuroplasticity. NIBS methods have been largely applied for improving paretic hand motor function and strokeassociated cognitive deficits. Recent studies suggest a possible effectiveness of these techniques also in the recovery of poststroke gait disturbance. This article is a selective review about functional investigations addressing the mechanisms of lower-limb motor system reorganization after stroke and the application of NIBS for neurorehabilitation.

“…Tanaka et al 21) noted that stimulation of the lower extremity motor area led to increased muscle strength of a single joint, activation of dorsiflexor muscles, and increased toe strength to grab. Tanaka et al 22) observed increased muscle strength in the quadriceps femoris in stroke patients. In the present study, tDCS application did not significantly improve normal subjects' power, but did increases the strength of a single muscle of a single joint; activation of the motor cortex did not influence power, unlike the study result reported by Antal et al 7) .…”

Abstract.[Purpose] The aim of this study was to examine the effects of noninvasive transcranial direct current stimulation (tDCS) on functional movement performance and balance of the lower extremities in normal people.[Subjects and Methods] The study randomly divided thirty normal adults into an experimental group and a pseudocontrol group in order to look at the effects of noninvasive tDCS on their agility, power, and balance. Each group also performed a treadmill exercise to evaluate whether brain activation was sustained.[Results] According to the intragroup comparison result, the experimental group showed significant differences in agility and balance, and significant differences occurred in balance in the pseudo-control group. In intergroup comparison, both groups significantly differed in agility and power.[Conclusion] tDCS activates the cerebral cortex, and therefore, is effective in improving functional movements of the lower extremities; it also significantly influences agility among functional movement elements of the lower extremities by maintaining activation of the premotor area during the next movement.

L'effet de la tDCS sur les membres infé rieurs se traduit é galement par une augmentation de la force à la suite d'une stimulation anodique (Tanaka et al, 2011).

Single Session of Transcranial Direct Current Stimulation Transiently Increases Knee Extensor Force in Patients With Hemiparetic Stroke

Abstract: Anodal tDCS transiently enhanced knee extensor strength. The modest increase was specific to the LL. Thus, tDCS might augment the rehabilitation of stroke patients when combined with lower extremity strengthening or functional training.
