Abstract
Lower limb motor dysfunction and lack of balance is one of the most common and disabling sequelae affecting stroke. Objectives: Analyze the effects of the combination of Transcranial Direct Stimulation (tDCS) with peripheral stimulation (PES) on the activity of the tibialis anterior (TA) paretic and balance of hemiparetic post stroke.
Highlights
Stroke often leads to a reduction in the activation of nerve pathways involved in somatosensory processing and the execution of motor actions, resulting in impaired motor control [1]
Subjects were randomized in 3 groups: PESa /tDCSp; PESa /tDCSa and PESp /tDCSa. Transcranial Direct Stimulation (tDCS) anode electrode was applied over injured motor cortex (C1/C2) and cathode uninjured (C1/C2) for 20 min associated with active dorsiflexion and peripheral stimulation (PES) for 30 min
Intragroup median frequency (MDF) significantly decreased (p
Summary
Stroke often leads to a reduction in the activation of nerve pathways involved in somatosensory processing and the execution of motor actions, resulting in impaired motor control [1] Among other complications, this condition generally leads to reduced muscle strength associated with altered muscle tone, which is denominated paresis [2]. Equinus is the limited upward movement of the foot due to hypotonus of the gastrocnemius and soleus muscles (triceps surae) and a reciprocal reduction or absence of strength in the tibialis anterior (TA) muscle [3] This dysfunction partially impedes the transference of weight to the affected limb, which anatomically interferes with postural reactions and balance [4]. When the sway surpasses the capacity of the muscle for reorganization through the inverted pendulum, the TA performs dorsiflexion (step strategy), thereby avoiding a fall [6]
