Virtual reality exergame in older patients with hypertension: a preliminary study to determine load intensity and blood pressure.

BACKGROUND: Lifestyle changes and physical activity can make an important contribution to reducing the risk factor for high blood pressure (BP). Whether virtual reality (VR) exergames are also appropriate and make a positive contribution to the reduction of BP has not yet been sufficiently investigated. Therefore, the aim of the study was to gain knowledge of the load intensities to be achieved during a VR exergame and to examine the short-term effects on BP. METHODS: For the preliminary study, 22 participants with hypertension over the age of 65 years were analyzed. The study took place in a mobile laboratory truck. All participants visited on two occasions. During visit 1, VR strength endurance training (VR-SET) and during visit 2, VR endurance training (VR-ET) was performed. Each VR session lasted approximately 25 min and was of a moderate intensity. Heart rate (HR) was measured across the entire session, as well as BP before and after the VR exergame. The Rating of Perceived Exertion (RPE) and task load using NASA Task Load Index were determined after each VR session. Included in the statistical analysis were the Shapiro-Wilk test, the paired t-test, the Wilcoxon test and ANOVA for repeated measures. RESULTS: During the "main part" (p < .001), at the "end" (p = .002) and for the "maximum HR" (p < .001), significant load differences between both VR sessions could be determined. In addition, significantly more participants in the VR-SET group achieved a moderate load intensity of at least 40% of heart rate reserve (p = .014). Regarding RPE, participants rated their subjectively perceived exertion significantly higher in the VR-SET than in the VR-ET (p = .028). Systolic BP decreased significantly in both VR sessions when compared before VR session and 5 min after VR session (p = .015; p = .003), as well as before VR session and 10 min after VR session (p = .018; p < .001). CONCLUSIONS: An individual moderate load intensity of 40% can be reached during VR-SET. In addition, a positive short-term effect of the VR exergame on BP behavior (postexercise hypotension) was observed after both VR sessions. The preliminary results indicate that a VR exergaming could lead to blood pressure lowering effects for older people with hypertension. TRIAL REGISTRATION: The study was registered in the German Clinical Trials Register (DRKS-ID: DRKS00022881, 07/09/2020, https://drks.de/search/de/trial/DRKS00022881 ).

[Support needs of care dependent individuals : Survey of general and specific needs for information, assistance and support of care dependent individuals and their relatives]. / Unterstützungsbedarfe pflegeempfangender Menschen : Erhebung allgemeiner und spezieller Informations­, Hilfe- und Unterstützungsbedarfe pflegeempfangender Menschen und ihrer Angehörigen.

BACKGROUND: In 2009, statutory regulations on information and counselling regarding nursing care needs, performed by so-called care advisors have been implemented for persons in need of long-term care and their relatives. In order to adequately prepare these care advisors, contemporary needs and requirements must be determined. The aim of the study was to determine the different needs of persons in need of long-term care and their relatives. METHOD: Care advisors were interviewed via an online survey tool using a standardized questionnaire. A 5-point Likert scale was used to determine the needs regarding information and advice on 16 specific topics. In general, overall needs regarding information and advice of care recipients and relatives were recorded using a 10-point scale (1 low and 10 high). Using classification and regression trees (CRT) and random forest, the correlation between the individual main topics and the general need for advice was analyzed. RESULTS: The participating care advisors (n = 276) rated the general demand for information of people in need of care and their relatives with a mean of 7.8 and 9.2, respectively. For those in need of care, the strongest association of general information needs was the topic of housing advice For the relatives, the topic social law aspects and benefits was the most relevant association. CONCLUSION: The general demand for information was rated very high. Since differences became obvious between those in need of care and their relatives, it is necessary to adjust care advice for these two groups.
