“…Additionally, several factors may underlie the mechanism by which seated balance training contributed to the recovery of standing balance performance: these include the fact that the upper body accounts for two-thirds of body mass, 10 11 and that the patient’s lower extremities were naturally activated when he reached far beyond the base of support while seated in response to the resulting load placed on them in the direction of motion. 11 …”

A male patient in his 40s was transferred to our hospital for rehabilitation of ataxia after right cerebellar and brainstem infarction. After 3 weeks of conventional physical therapy, his activities of daily life successfully improved with an increase in the functional impedance measure from 101 to 124. However, he still fell short of gaining a higher level of balance function, which was necessary for his job as a standup forklift driver. We introduced virtual reality-guided balance training. The training was performed for approximately 40 min on weekdays for 2 weeks. As a result, the Scale for the Assessment and Rating of Ataxia score decreased from 5 to 1, Functional Balance Scale score improved from 48 to 56, and Mini-Balance Evaluation Systems Test score increased from 20 to 28. The trunk sway disappeared clinically. He regained confidence and returned to work after an additional 2 weeks of physical therapy.

“…VR creates interactive, multimodal sensory stimuli that offer unique advantages over other approaches in neurorehabilitation. VR facilitates an easy, prompt, quantitative, and replicable training method by accurately setting the distance, angle, height, or other parameters in a 3D virtual space [4,7]. The therapist's only responsibility is to adjust these parameters by inputting numbers on the operating panel of the computer.…”

“…Recently, some researchers reported successfully managed cases of muscle atrophy or cerebellar ataxia resistant to traditional therapeutic management using VR-guided, dual-task, body balancing training (mediVR KAGURA, mediVR, Inc., Toyonaka, Japan, commercially available from February 4, 2019) [7,8]. The mediVR KAGURA system was developed to help patients regain their walking ability through the improvement of dual-task processing and trunk balancing [7,8].…”

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.

“…mediVR KAGURA ® (mediVR, Inc., Osaka, Japan) has been reported to improve walking ability without increasing lower limb muscle strength [ 7 , 8 ]; however, the mechanism remains unclear. Exercise therapy with the use of virtual reality (VR) requires quick arm movements extending to spatial targets.…”

Virtual reality (VR)-guided exercise therapy using mediVR KAGURA has been reported to improve gait function by extending the arm to spatial targets while sitting. We aimed to investigate toe and trunk–pelvic function and plantar sensation during gait in a postoperative patient with hallux valgus. A 60-year-old woman, whose foot deformities had improved 6 months earlier, participated in the study. The exercise therapy interventions were performed twice weekly for 15 min. This study used an A-B-A design: 1-week pre-phase, 3-week intervention phase, and 2-week post-phase. The plantar pressure distribution and thoracic and pelvic displacements during gait were recorded at the end of each phase. The tactile pressure thresholds of the foot were determined before and after each exercise. The maximum force and impulse under the hallux increased after the intervention. The sensory threshold of the hallux was reduced. The amplitude of the thoracic and pelvic displacement was shortened in lateral and extended in the vertical and progressional directions after the intervention. We found that a 3-week VR-guided exercise improved toe function, plantar sensation, and postural adjustment of the trunk and pelvis during gait in a patient who had undergone surgery for hallux valgus, and the effects continued for 2 weeks.
