Rate Of Improvement

Virtual reality (VR)-based rehabilitation has been used in lower limb amputees; however, the extent to which VR is effective in reacquiring symmetrical gait in lower limb amputees is unclear. The purpose of this study was to confirm whether a VR intervention is effective in obtaining a simulated prosthetic gait. The participants were 24 healthy males who had never worn a simulated prosthesis. They were divided into three groups: VR, tablet, and control groups. The intervention consisted of 5 min of in situ stepping on parallel bars and watching a video of a simulated prosthetic leg walker on a head-mounted display or a tablet. Measurements included Gait Up parameters during a 10-m walk and immersion scores. After the intervention, there was a significant interaction between walking speed and leg swing speed in the VR group. The rate of improvement in walking speed and immersion scores was significantly higher in the VR group than in the other two groups, and there was a significant positive correlation between the rate of improvement and immersion scores. Compared to the tablet and control groups, the VR group showed the highest rate of immersion and improvement in walking speed.

Abstract Objective: To evaluate the effectiveness of immersive Virtual Reality (VR) in laboring women on patient satisfaction as a distractive tool and pain relief.Methods: Randomized, controlled clinical trial with 42 laboring women allocated to VR intervention and control groups. Among the VR group, patient satisfaction with the use of VR was assessed by a Virtual Reality Satisfaction Survey and questioning whether they would choose VR in future labor. As a primary outcome patient satisfaction scores regarding the overall labor and delivery experience were compared between the two groups. A secondary outcome was pain assessed by a visual pain rating scale in the early and active phases of labor in both groups. Psychometric information was also collected from participants in each group using Beck Anxiety Inventory and Beck Depression Inventory. Results: We observed a high level of patient satisfaction with the use of immersive VR during labor. The survey revealed a mean satisfaction score of 89.6 ± 10.8 out of a maximum of 100. 20 out of 21 (95%) women in the VR group stated that they would like to use VR again in future labor. VR improved pain scores in early labor and contributed positively to overall labor and delivery experience. The mean pain score pre-VR was 2.6±1.2 compared to 2.0±1.3, post-VR, respectively (p<0.01). Anxiety and depression scores were similar in the intervention and control groups (p=0.103, p=0.13, respectively). Conclusion: Immersive VR application during labor was feasible and associated with higher patient satisfaction based on our study. VR also improved pain scores in early labor before epidural placement. Immersive VR may find a place as an adjunct in Labor and Delivery Units to improve the lengthy labor experience for women. Larger studies are needed to confirm these observations. Trial Registration: ClinicalTrials.gov: NCT05032456 / 02/09/2021https://clinicaltrials.gov/ct2/show/NCT05032456

SUMMARY OBJECTIVE: This study aimed to investigate the effect of virtual reality application on experimental ischemic pain created with a blood pressure instrument in healthy volunteers. METHODS: The research sample consisted of 172 volunteer adult students who conformed to the inclusion criteria. These individuals were assigned into an experimental (n=86) and a control group (n=86) by a simple randomization method. All individuals in the experimental and control groups wereexperimentally subjected to pain for two minutes by applying 260 mmHg of pressure 3-4 cm above the antecubital region of the left arm with an aneroid adult-type blood pressure instrument. During the procedure, the volunteers in the experimental group watched virtual reality images, while those in the control group received no intervention. Immediately after the procedure, the pain levels of the individuals in both groups were assessed with a Visual Analog Scale (VAS). RESULTS: We found that the mean pain score of the individuals in the experimental group was 2.62±1.82, and that of individuals in the control group was 5.75±1.65. Results of the statistical analysis showed a statistically significant difference between the mean pain scores of the individuals in the experimental and control groups (p<0.001). CONCLUSION: This study found that the use of virtual reality was effective in reducing the level of pain in healthy individuals. This method used a smartphone with widespread availability and ease of transportation, which can be used by health professionals as a non-pharmacological method in the management of pain.

Abstract Certain striped patterns can induce illusory motion, such as those used in op-art. The visual system and the vestibular system work together closely, and so it is possible that illusory motion from a visual stimulus can result in uncertainty in the vestibular system. This increased uncertainty may be measureable in terms of the magnitude of head movements. Head movements were measured using a head-mounted visual display. Results showed that stimuli associated with illusory motion also seem to induce greater head movements when compared to similar stimuli. Individuals with migraine are more susceptible to visual discomfort, and this includes illusory motion from striped stimuli. However, there was no evidence of increased effect of illusory motion on those with migraine compared to those without, suggesting that while motion illusions may affect discomfort judgements, this is not limited to only those with migraine.

Fitness Levels

Background and Objectives: Stoma surgery is linked to reduced physical activity in colon cancer survivors and leads to decreased physical fitness, activity of daily living dysfunction, and poorer quality of life. However, few studies have investigated the physical fitness levels of colon cancer survivors living with stomas. This study aimed to compare the physical fitness levels of colon cancer survivors with stomas and healthy adults, assessing them in a variety of dimensions (e.g., strength and flexibility) and in terms of physical fitness age (PFA), an integrated index of overall fitness. Materials and Methods: The study population consisted of 17 colon cancer survivors with (stoma group) and 20 healthy adults without (control group) a stoma. Physical fitness was assessed using a battery of five tests: repeated back-and-forth steps, 30-s chair stand, chair sit-and-reach, grip strength, and single-leg balance with eyes closed. Respective performance values were converted into PFA, which was compared between the stoma and control groups. Fitness indicators were compared between groups by analysis of covariance, and PFA and chronological age (CA) by paired t-tests. Results: The mean ages (±standard deviation) of the stoma and control groups were 74.1 ± 7.9 and 73.5 ± 7.1 years, respectively. Colon cancer survivors with stomas had poorer lower limb muscular strength, endurance, and flexibility than controls. In the stoma group, the marginal mean (±standard error) PFA was calculated to be 82.5 ± 3.7 years, significantly higher than the CA and PFA of the control group (69.6 ± 3.9 years). Conclusions: Colon cancer survivors with stomas have lower physical fitness levels than healthy adults, with apparent deficits in lower limb flexibility, muscular strength, and endurance. Our findings demonstrated the need for exercise interventions in this population, focusing on these dimensions of fitness. However, our results should be corroborated by means of a larger-scale comparison in future studies.

Objective To investigate whether immersive virtual reality (VR) distraction could decrease pain during postoperative dressing changes. Methods This was a prospective, open-label randomized clinical trial that enrolled patients that had undergone haemorrhoidectomy. Patients were randomly assigned to one of two groups: a control group that received the standard pharmacological analgesic intervention during dressing change and a VR group that received VR distraction during dressing change plus standard pharmacological analgesic intervention. Pain scores and physiological measurements were collected before, during and after the first postoperative dressing change. Results A total of 182 patients were randomly assigned to the control and VR groups. The baseline characteristics of the VR and control groups were comparable. There was no significant difference in mean pain scores prior to and after the dressing change procedure between the two groups. The mean pain scores at the 5-, 10-, 15- and 20-min time-points during the first dressing change were significantly lower in the VR group compared with the control group. Heart rates and oxygen saturation were not significantly different between the two groups. Conclusion Immersive VR was effective as a pain distraction tool in combination with standard pharmacological analgesia during dressing change in patients that had undergone haemorrhoidectomy.

Present Pilot Study

Virtual reality (VR) is an often-used instrument in sports science research and practical training. However, VR studies with experienced athletes and sports specific tasks are rare. Furthermore, the transfer from interventions in VR into reality is even less investigated. It is possible to analyze benefits of VR using in-situ studies comparing human behavior in VR with reality. If no differences occur in the human behavior, then VR would be appropriate for interventions to improve athletes’ performance. Therefore, we let seven karate athletes respond each to ten attacks of a real attacker (reality) and a virtual attacker (VR using a Head Mounted Display) and compared the parameters “response quality” and “attack recognition” under both conditions. As attacks we chose Gyaku-Zuki (reverse punch, GZ) and Kizami-Zuki (attack with the front arm, KZ). ANOVAs and sign tests showed isolated cases of significant differences between both conditions: response quality in KZ, and attack recognition for 150ms in GZ, all p0.05). The remaining comparisons showed no significant differences (p>0.05). We conclude that further research is needed but the results of the present pilot study are promising to assume that VR is suitable for applications because similar performance outcome in reality and VR were obtained.
