Video game-based and conventional therapies in patients of neurological deficits: an experimental study

Purpose In the past few years, medicine has upgraded its therapeutic techniques and practices, with the use of various modern methods that are due to advancement in technology and sciences. It is recognized that the physical health of the patients is significantly associated to their mental state, their motivation and engagement in overcoming the illness. This paper presents experimental comparison between virtual reality (VR) technology and conventional mode of therapy for physical rehabilitation among patients of neurological deficits. The objective was to explore the effectiveness of VR during physical interactions with different game-like virtual environment and potentially leading to increased mental health (i.e., lower depression, anxiety and stress), self-esteem, social support and intrinsic motivation (task-based competence, choice and interest). Method The study sample consisted of thirty-four subjects with Cerebral palsy (CP), Traumatic brain injury (TBI), Spinal cord injury, Stroke and Parkinson’s disease; divided into two experimental groups virtual reality exercise group (n = 17), and conventional therapy group (n = 17); who have upper- or lower-limb impairment. Results The outcome measures revealed significant differences across pretest and post-test conditions of both the experimental groups. Findings emerged from the study showed noticeable effectiveness of virtual-reality based rehabilitation in TBI, stroke and CP patients. Relationships between study variables and demographic variables (age and gender) were also presented. Conclusion This study opens the way for future researchers, psychologists, physiotherapist and other practitioners to do more extensive work in the domain of virtual reality with different sample, constructs and approaches. Implications for rehabilitation It has become increasing important to introduce new state-to-art technologies in domain of rehabilitation. People are reluctant to use all the traditional modes of treatment. As these conventional ways of treatment are least motivating and interesting to indulge the patients without force and burden. It is evident in the present study that addition of virtual reality-based exercise increases the self-motivated balance during functional task in contrast to conventional and task-dependent training participants. This study opens the way for future researchers to do more extensive work in this domain.

Virtual Reality-Based Exercise with Exergames as Medicine in Different Contexts: A Short Review.

There is enough evidence that, nowadays, the sedentary lifestyle is one of the major health problems worldwide, linked to many chronic diseases, including mental comorbidities, systemic hypertension, metabolic dysregulation, and cancer. Although health societies recommend engagement to physical activities, there is an overwhelming number of people remaining sedentary, even knowing the health benefits of regular exercises. One of the main factors that justifies this scenario is the lack of motivation, which is a barrier to people intended to start new habits for health. Considering this previous information, new alternatives for exercises may help people engage in a healthier lifestyle. Technology has contributed to this with devices that allow movements based on virtual reality approaches, including the exergames. These are games available even in commercial devices, as video-games, that allow people to work with different physical components. Furthermore, exergames add cognitive gain through its dual-task characteristic. Moreover, due to the combination of these benefits, they are feasible to acquire, and easy to use. Exergames are not only a potential strategy to reduce sedentary lifestyle but also a good method to improve health gains and rehabilitation in different populations and pathological conditions: older adults, stroke survivors, and Parkinson's disease. In this review, we aim to demonstrate some conditions that literature supports the intervention with exergames due to its physical and cognitive benefits. Furthermore, at the end of this review, we also explore the neurobiological mechanisms behind virtual-reality based exercises.

Effects of Virtual Reality-Based Exercise Imagery on Pain in Healthy Individuals.

Objective Virtual reality (VR) is an advanced technology that can be used to attenuate pain. The present study aimed to investigate which method was more effective for pain management: VR combined with exercise imagery or VR distraction. Methods Fifty-two healthy students participated in this randomized cross-over controlled trial. One VR-based task aimed to passively use the imagery of driving a car as a distraction intervention (the driving group), whereas the other VR-based task aimed to use exercise imagery (running) to actively engage the participants in movement (the running group). The mechanical pressure pain thresholds of the quadriceps and forearm and the heat pain threshold of the hand of each subject were measured before, during, and after each VR task. The differences between the values at each time point and the differences between the groups were analyzed. Results The pressure and heat pain thresholds were significantly greater during VR task than those before VR task in both driving and running groups. The changes in the pressure pain thresholds that occurred during VR task were significantly higher in the running group than in the driving group. The difference between groups gradually declined after VR task. Conversely, there was no significant difference in the changes in the heat pain thresholds between the groups both during VR task and after VR task. Conclusions VR combined with exercise imagery has a greater effect on pressure pain thresholds, but not heat pain thresholds, than VR distraction.

Evaluation of the effectiveness of a Virtual Reality-based exercise program for Unilateral Peripheral Vestibular Deficit.

BACKGROUND: Recently, two types of movement sensors have been introduced into Virtual Reality (VR) therapy: motion trackers and force-plate platforms. Combining these two methods could produce better rehabilitation outcomes. Such devices, encompassing motion trackers and force platforms, are referred to as “hybrid” VR units.OBJECTIVE: To assess the effectiveness of a low-cost hybrid VR based vestibular rehabilitation programMETHODS: A prospective, non-randomized, controlled group study comparing training using a hybrid VR unit (Group 1 n = 25) vs. static posturography with visual feedback (Group 2 n = 25) in patients with peripheral vestibular dysfunction was conducted. The subjects underwent 10 training sessions over 10 days (30 minute sessions). All were examined on a posturography platform at the start and 1 month after rehabilitation and completed the Vertigo Symptom Scale – Short Form (VSS-SF) questionnaire.RESULTS:Both groups demonstrated improvement in posturographic parameters, which were statistically significant, but when comparing results between both groups there were no differences. The patients reported improvement in their subjective perception of symptoms on the VSS-SF scale, which were statistically significant in both groups, but greater in the VR group.CONCLUSIONS: Both methods reduce postural sway, however subjective reduction of symptoms was greater in the VR group.

Effects of physical, virtual reality-based, and brain exercise on physical, cognition, and preference in older persons: a randomized controlled trial

BackgroundPhysical exercise (PE), virtual reality-based exercise (VRE), and brain exercise (BE) can influence physical and cognitive conditions in older persons. However, it is not known which of the three types of exercises provide the best effects on physical and cognitive status, and which exercise is preferred by older persons. This study compared the effects of PE, VRE, and BE on balance, muscle strength, cognition, and fall concern. In addition, exercise effort perception and contentment in older persons was evaluated.MethodsEighty-four older persons (n = 84) were randomly selected for PE, VRE, BE, and control groups. The exercise groups received 8-week training, whereas the control group did not. Balance was assessed by Berg Balance Scale (BBS) and Timed Up and Go test (TUG), muscle strength by 5 Times Sit to Stand (5TSTS) and left and right hand grip strength (HGS), cognition by Montreal Cognitive Assessment (MoCA) and Timed Up and Go test Cognition (TUG-cog), fall concern by Fall Efficacy Scale International (FES-I), exercise effort perception by Borg category ratio scale (Borg CR-10), and exercise contentment by a questionnaire.ResultsAfter exercise, PE significantly enhanced TUG and 5TSTS to a greater extent than VRE (TUG; p = 0.004, 5TSTS; p = 0.027) and BE (TUG; p = 0,012, 5TSTS; p < 0.001). VRE significantly improved MoCA (p < 0.001) and FES-I (p = 0.036) compared to PE, and 5TSTS (p < 0.001) and FES-I (p = 0.011) were improved relative to BE. MoCA was significantly enhanced by BE compared to PE (p < 0.001) and both MoCA and TUG-cog were improved compared to VRE (p = 0.04). PE and VRE significantly (p < 0.001) increased Borg CR-10 in all exercise sessions, whereas BE showed a significant improvement (p < 0.001) in the first 4 sessions. Participants had a significantly greater satisfaction with BE than controls (p = 0.006), and enjoyed VRE and BE more than PE (p < 0.001). Subjects in all exercise groups exhibited benefits compared to the control group (p < 0.001).ConclusionsPE provided the best results in physical tests, VRE produced measurable improvements in physical and cognition scores, while BE enhanced cognition ability in older persons. Older persons preferred VRE and BE compared to PE. Both exercises are suggested to older persons to improve physical and cognitive conditions.

Effect of a Virtual Reality-Based Exercise Program on Fatigue in Hospitalized Taiwanese End-Stage Renal Disease Patients Undergoing Hemodialysis.

The purpose of this study was to evaluate the short-term effect of a virtual reality-based exercise program on fatigue in patients with end-stage renal disease (ESRD) who receive hemodialysis (HD). In this quasi-experimental study design, an experimental group (n = 32) received virtual reality training that promoted exercise, and a control group (n = 32) received routine care (advice on physical activities). Fatigue and physiologic parameters were assessed pretest (before intervention) as well as posttest (4 weeks after the onset of intervention). Our results showed that patients in the experimental group had significantly lower levels of overall fatigue, reduction in vigor and motivation, distress and loss of control in mood, and higher hemoglobin levels compared with the control group. ANCOVA revealed that there were no differences in overall fatigue and different domains of fatigue. Exercise only increased the blood urea nitrogen (BUN) and creatinine levels significantly in the intervention group.

Influence of a virtual reality-based exercise protocol on the sit-to-stand activity kinematic variables in pregnant women: a randomized controlled trial

Abstract AIMS Changes resulting from the gestational period may lead to changes in the biomechanics of women, which can alter the performance of functional activities such as sit-to-stand. Thus, the objective of this study was to investigate the influence of a virtual reality-based exercise protocol on the kinematic variables of the sit-to-stand movement in women in their second and third gestational trimesters. METHODS The sample consisted of 44 women selected according to the eligibility criteria, allocated into 4 groups: control group, 2nd trimester (CG2T); experimental group, 2nd trimester (EG2T); control group, 3rd trimester (CG3T); and experimental group, 3rd trimester (EG3T). All the volunteers answered the identification and evaluation form and were sent to the kinematic evaluation through the Qualisys Motion Capture System®. An intervention with game therapy was performed in 12 sessions of 30 minutes each, three times a week. RESULTS No statistically significant differences were found intra- (P> 0.54) and inter-groups (P> 0.059) for kinematic variables. However, there was a tendency for improvement in the analyzed variables after the proposed protocol. CONCLUSIONS The data obtained suggest that the use of the Nintendo Wii Fit Plus® was not able to influence sit-to-stand kinematic variables in the analyzed women.

Effects of a virtual reality-based exercise program on functional recovery in stroke patients: part 1.

This study aimed to determine the effects of a virtual reality exercise program using the Interactive Rehabilitation and Exercise System (IREX) on the recovery of motor and cognitive function and the performance of activities of daily living in stroke patients. [Subjects] The study enrolled 10 patients diagnosed with stroke who received occupational therapy at the Department of Rehabilitation Medicine of Hospital A between January and March 2014. [Methods] The patients took part in the virtual reality exercise program for 30 minutes each day, three times per week, for 4 weeks. Then, the patients were re-evaluated to determine changes in upper extremity function, cognitive function, and performance of activities of daily living 4 weeks after the baseline assessment. [Results] In the experimental group, there were significant differences in the Korea-Mini Mental Status Evaluation, Korean version of the modified Barthel index, and Fugl-Meyer assessment scores between the baseline and endpoint. [Conclusion] The virtual reality exercise program was effective for restoring function in stroke patients. Further studies should develop systematic protocols for rehabilitation training with a virtual reality exercise program.

Unsupervised Virtual Reality-Based Exercise Program Improves Hip Muscle Strength and Balance Control in Older Adults: A Pilot Study

ObjectiveTo assess the effects of an unsupervised virtual reality (VR)-based exercise program on hip muscle strength and balance control in older adults. DesignControlled cohort repeated-measures experimental design, a pilot study. SettingUniversity research laboratory. ParticipantsAmbulatory older adults (N=32) from a local community. InterventionThe VR group (n=18; mean ± SD, 68.28±3.74y; 4 men) completed the VR-based exercise program, whereas the remaining subjects in the control group (n=14; mean ± SD, 66.21±3.87y, 1 man) were asked to continue their daily routine for 8 weeks. Main Outcome MeasuresHip muscle strength was measured using a multimodal dynamometer, and ground reaction force using the backward stepping test and the results of the crossover stepping test were recorded using a force platform. ResultsThe VR group showed significant improvement in hip muscle strength of the extensors, flexors, adductors, and abductors after 8 weeks (all P≤.001). However, no significant improvement was observed in the control group. The VR group had significantly greater ground reaction force on the backward stepping test (with eyes opened and closed) (all P<.005) and the crossover stepping test (with eyes opened and closed) (all P≤.001) compared with those at baseline. However, no significant improvement was observed in the control group. ConclusionsThe VR-based exercise program includes the role of supervisor and feedback, which is important for older adults. Therefore, a VR-based exercise program may be a useful tool to improve decreased physical function in older adults as a home-based exercise.
