As it is well-known that regular physical activity has positive effects on individual physical and mental health and thus is an important prerequisite for healthy aging, digital technologies are also increasingly used to promote unstructured and structured forms of physical activity. However, in the course of this development, several terms (e.g., Digital Health, Electronic Health, Mobile Health, Telehealth, Telemedicine, and Telerehabilitation) have been introduced to refer to the application of digital technologies to provide health-related services such as physical interventions. Unfortunately, the above-mentioned terms are often used in several different ways, but also relatively interchangeably. Given that ambiguous terminology is a major source of difficulty in scientific communication which can impede the progress of theoretical and empirical research, this article aims to make the reader aware of the subtle differences between the relevant terms which are applied at the intersection of physical activity and Digital Health and to provide state-of-art definitions for them.}, language = {en} } @article{HofmannVoellerNagelsetal.2015, author = {Hofmann, Reiner and V{\"o}ller, Heinz and Nagels, Klaus and Bindl, Dominik and Vettorazzi, Eik and Dittmar, Ronny and Wohlgemuth, Walter and Neumann, Till and St{\"o}rk, Stefan and Bruder, Oliver and Wegscheider, Karl and Nagel, Eckhard and Fleck, Eckart}, title = {First outline and baseline data of a randomized, controlled multicenter trial to evaluate the health economic impact of home telemonitoring in chronic heart failure - CardioBBEAT}, series = {Trials}, volume = {16}, journal = {Trials}, publisher = {BioMed Central}, address = {London}, organization = {CardioBBEAT Investigators}, issn = {1745-6215}, doi = {10.1186/s13063-015-0886-8}, pages = {12}, year = {2015}, abstract = {Background: Evidence that home telemonitoring for patients with chronic heart failure (CHF) offers clinical benefit over usual care is controversial as is evidence of a health economic advantage. Methods: Between January 2010 and June 2013, patients with a confirmed diagnosis of CHF were enrolled and randomly assigned to 2 study groups comprising usual care with and without an interactive bi-directional remote monitoring system (Motiva (R)). The primary endpoint in CardioBBEAT is the Incremental Cost-Effectiveness Ratio (ICER) established by the groups' difference in total cost and in the combined clinical endpoint "days alive and not in hospital nor inpatient care per potential days in study" within the follow-up of 12 months. Results: A total of 621 predominantly male patients were enrolled, whereof 302 patients were assigned to the intervention group and 319 to the control group. Ischemic cardiomyopathy was the leading cause of heart failure. Despite randomization, subjects of the control group were more often in NYHA functional class III-IV, and exhibited peripheral edema and renal dysfunction more often. Additionally, the control and intervention groups differed in heart rhythm disorders. No differences existed regarding risk factor profile, comorbidities, echocardiographic parameters, especially left ventricular and diastolic diameter and ejection fraction, as well as functional test results, medication and quality of life. While the observed baseline differences may well be a play of chance, they are of clinical relevance. Therefore, the statistical analysis plan was extended to include adjusted analyses with respect to the baseline imbalances. Conclusions: CardioBBEAT provides prospective outcome data on both, clinical and health economic impact of home telemonitoring in CHF. The study differs by the use of a high evidence level randomized controlled trial (RCT) design along with actual cost data obtained from health insurance companies. Its results are conducive to informed political and economic decision-making with regard to home telemonitoring solutions as an option for health care. Overall, it contributes to developing advanced health economic evaluation instruments to be deployed within the specific context of the German Health Care System.}, language = {en} } @article{HadzicEichlerVoelleretal.2022, author = {Hadzic, Miralem and Eichler, Sarah and V{\"o}ller, Heinz and Salzwedel, Annett}, title = {Akzeptanz und Nutzung eines telemedizinischen Rehabilitationsprogramms f{\"u}r Patienten mit Knie- oder H{\"u}ft-Totalendoprothese}, series = {Bewegungstherapie und Gesundheitssport : B \& G ; offizielles Organ des Deutschen Verbandes f{\"u}r Gesundheitssport und Sporttherapie e.V.

The effectiveness of telemedical exercise therapy for patients after implantation of a total knee or hip prosthesis and subsequent rehabilitation has already been examined in a randomized controlled study. This article focuses on the patient's acceptance and usage behaviour with regard to the tele-rehabilitation system. Methodology: 48 patients (53 +/- 7 years; 26 women; 35 hip/13 knee TEP) were questioned after a three-month telemedical movement therapy using the Telehealth Usability Questionnaire (TUQ) to determine the acceptance of the technology. The questionnaire consisted of 21 items (seven-point Likert scale) in six scales (e. g. usefulness, quality of interactions, reliability). System-specific questions were summarized on an additional scale. The results were presented as a percentage of the scale (100 estimates complete agreement). The usage behaviour was examined using system-generated process data for training and integrated voice/text messages. Results: The TUQ scales "Usefulness" (Mdn 95.2) and "Ease of use and learnability" (Mdn 92.9) were rated the highest, while "Reliability" (Mdn 57.1) and "Quality of interactions" ( Mdn 71.4) showed the lowest levels. The system-specific scale was placed in the upper quartile (Mdn 85.7). In the first week, 39 patients (81\%) and in the second 45 patients (94\%) performed at least one training exercise with the system. The proportion of active patients (>= 1 exercise/week) decreased in the further course to 75\% (n=36) in the 7th week and 48\% (n=23) in the 12th week. The system communication options were initially used frequently after the start of therapy: in the first week, 42 patients (88\%) sent messages, 47 patients (98\%) received messages from their therapist respectively. In week 7, 9 (19\%) and 13 (27\%) patients sent/received messages via the system respectively. Conclusion: Most of the patients perceived telemedical movement therapy as useful and user-friendly and seemed to be largely satisfied with the system. This proved to be well suited for short-term use of 6 to 8 weeks following subsequent rehabilitation.}, language = {de} }
