Effect of galvanic vestibular stimulation on axial symptoms in Parkinson's disease.

Postural imbalance, abnormal axial posture, and axial rigidity are the characteristic features of Parkinson's disease (PD), and they are referred to as axial symptoms. The symptoms are difficult to manage since they are often resistant to both L-DOPA and deep brain stimulation. Hence, other treatments that can improve Parkinsonian axial symptoms without adverse effects are required.

Can Postural Instability Respond to Galvanic Vestibular Stimulation in Patients with Parkinson's Disease?

Objective: Galvanic vestibular stimulation (GVS) activates the vestibular afferents, and these changes in vestibular input exert a strong influence on the subject's posture or standing balance. In patients with Parkinson's disease (PD), vestibular dysfunction might contribute to postural instability and gait disorders.

Methods: Current intensity was increased to 0.

Influence of the stimulus parameters of galvanic vestibular stimulation on unilateral spatial neglect.

Galvanic vestibular stimulation (GVS) stimulates the vestibular system electrically with low-amplitude direct current through surface electrodes applied to the left and right mastoids. The effects of GVS on unilateral spatial neglect (USN) in poststroke patients were recently reported, but the influence of the current intensity and application duration of GVS on USN has not been sufficiently investigated. Here we explored the influence of these stimulus parameters on USN.

Galvanic vestibular stimulation may improve anterior bending posture in Parkinson's disease.

This study investigated the effects of binaural monopolar galvanic vestibular stimulation (GVS), which likely stimulates the bilateral vestibular system, on the anterior bending angle in patients with Parkinson's disease (PD) with anterior bending posture in a single-blind, randomized sham-controlled crossover trial. The seven PD patients completed two types of stimulation (binaural monopolar GVS and sham stimulation) applied in a random order 1 week apart. We measured each patient's anterior bending angles while he or she stood with eyes open and eyes closed before/after the stimulations.

Effects of galvanic vestibular stimulation combined with physical therapy on pusher behavior in stroke patients: a case series.

Background: A recent study investigated the effects of galvanic vestibular stimulation (GVS) on pusher behavior (PB) in post-stroke patients. However, there have been no reports about the effects of multisession GVS on PB.

Objective: The purpose of this study was to investigate the feasibility and effects of multisession GVS combined with physical therapy for PB in stroke patients.
