Abstract BackgroundPersistent postural-perceptual dizziness (PPPD) is a newly defined disorder of functional dizziness. Due to its recent discovery, definitive treatment for PPPD has not been established; therefore, this study aimed to measure the effectiveness of virtual reality (VR)-guided, dual-task, body trunk balance training using the mediVR KAGURA system for the treatment of PPPD.MethodsData from patients with PPPD collected from January 1, 2021 to February 28, 2021 were reviewed. Additionally, healthy people were included as controls. VR-guided training was performed using 100 tasks for 10 min. Equilibrium tests were performed at baseline and immediately after VR-guided training to examine the effectiveness of static and dynamic balance ability. Additionally, assessments of clinical questionnaire-based surveys of balance disorders were performed at baseline and 1 week after VR-guided training to examine the effects on the symptoms related to balance disorders. The primary outcome was the usefulness of static and dynamic body balance and NPQ scores.ResultsVR-guided training using mediVR KAGURA improved objective symptoms, including static and dynamic postural stability (relating to somatosensory and visual weighting, respectively) even when the training was conducted once for 10 min. Additionally, VR-guided training improved the Hospital Anxiety and Depression Scale score and the Niigata PPPD Questionnaire score, 1 week after a 10-min training session. ConclusionVR-guided training was found to be a viable method in managing the balancing ability, anxiety, and symptoms of patients with PPPD. VR-guided training offers safety and reduction of human resources; however, its clinical efficiency warrants further evaluation in prospective studies.Trial registrationInstitutional Ethics Committee of Kitano Hospital, approval number: 1911003.

Abstract The simultaneous performance of a secondary task while walking (i.e., dual tasking) increases motor-cognitive interference and fall risk in older adults. Combining transcranial direct current stimulation (tDCS) with the concurrent performance of a task that putatively involves the same brain networks targeted by the tDCS may reduce the negative impact of dual-tasking on walking. We examined whether tDCS applied while walking reduces the dual-task costs to gait and whether this combination is better than tDCS alone or walking alone (with sham stimulation). In 25 healthy older adults (aged 75.7±10.5yrs), a double-blind, within-subject, cross-over pilot study evaluated the acute after-effects of 20 minutes of tDCS targeting the primary motor cortex and the dorsal lateral pre frontal cortex during three separate sessions:1) tDCS while walking on a treadmill in a virtual-reality environment (tDCS+walking), 2) tDCS while seated (tDCS+seated), and 3) walking in the virtual-reality environment with sham tDCS (sham+walking). The complex walking condition taxed motor and cognitive abilities. During each session, single- and dual-task walking and cognitive function were assessed before and immediately after stimulation. Compared to pre-tDCS performance, tDCS+walking reduced the dual-task cost to gait speed (p=0.004) and other gait features (e.g., variability p=0.02), and improved (p<0.001) executive function (Stroop interference score). tDCS+seated and sham+walking did not affect the dual-task cost to gait speed (p>0.17). These initial findings demonstrate that tDCS delivered during challenging walking ameliorates dual-task gait and executive function in older adults, suggesting that the concurrent performance of related tasks enhances the efficacy of the neural stimulation and mobility.

Improve Motor Function

Introduction: Individuals living with chronic stroke have weakness and increased neuromuscular fatigue in the paretic leg, which can limit walking ability and endurance. In cardiac and healthy populations, ischemic preconditioning (IPC) is a widely studied, effective, non-invasive stimulus which not only improves vascular function, but also motor performance. IPC occurs when the tissue of interest is exposed to repeated, short bouts of ischemia, which can improve motor function by enhancing vascular, neural and muscle function. IPC has not been tested as a method to improve motor function in individuals post-stroke. Hypothesis: Two weeks of IPC training on the paretic leg will improve leg strength and time-to-task failure (TTF) during a fatiguing muscle contraction. Methods: A feasibility study of 4 individuals (3 female, 1 male) with chronic stroke (20 ± 4 years) was conducted. A Biodex dynamometer was used to assess paretic leg knee extensor maximal voluntary contraction (MVC). To assess muscle fatigability, subjects maintained a sustained contraction equal to 30% of their MVC until failure using visual feedback. After baseline testing, subjects made six visits to the laboratory over a two week period to have IPC performed on their paretic leg. A blood pressure cuff was inflated on the thigh to 225 mmHg for five, five-minute bouts per session. Five minutes of rest was given between inflation cycles. After the last session, subjects returned within 48 hours to have MVC and TTF reassessed. Results: Three subjects completed all study procedures. One subject withdrew for medical reasons unrelated to the study. The IPC procedure was well tolerated by all subjects. After two-week IPC training, knee extensor MVC increased in the paretic leg (45.0 ± 2.7 Nm vs. 52.6 ± 5.7 Nm). Fatigability of the muscles was dramatically reduced after IPC training as TTF tripled (359 ± 180 seconds vs. 1097 ± 343 seconds). Conclusions: We are the first group to show that IPC is a well-tolerated and effective stimulus to improve paretic leg strength and reduce muscle fatigability in subjects with chronic stroke. The results of this pilot study warrant a larger study to determine whether IPC improves muscle performance post-stroke through neural, vascular, or muscle-related mechanisms.

Underlying Causes

Balance impairment at advanced age is a serious medical problem that often has significant implications and affects the quality of the patient’s life. Among the underlying causes are overall slowness of motor response and vestibular syndrome. Virtual reality exergames, including reaction and balance training, hold promise for managing balance dysfunction. The aim of this study was to investigate the effects of a combination rehabilitation program containing elements of virtual reality exergame on the postural and psychophysiological parameters of elderly patients with small vascular disease The study was conducted in 24 patients with small vascular disease (median age: 66 years). All patients underwent a virtual reality rehabilitation program. Psychophysiological, postural and clinical evaluations were performed at baseline and after the program was completed. Balance function measured on the Berg scale improved significantly and was 53 [52; 55] after the training program vs 50 [45; 54] at baseline (p < 0.05). The strategy of balance control also changed: the Romberg ratio was 266 [199.5; 478.5] before rehabilitation and 221 [149.25; 404] after the program was completed (p < 0.05). The most pronounced changes in the measured psychophysiological parameters occurred in the simple audiomotor reaction, which improved from 210 [174.25; 245.5] at baseline to 180.5 [170.5; 208] after rehabilitation (p < 0.05). Thus, the combination balance and reaction virtual reality training is an effective rehabilitation method for advanced-age patients with balance impairment.
