  abstract  = {Objective of the study: The long-term use of telemedical programs depends not only on their effectiveness, but also on patient acceptance and satisfaction. 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.},

  abstract  = {Return to work (RTW) is a pivotal goal of cardiac rehabilitation (CR) in patients after acute cardiac event. We aimed to evaluate cardiopulmonary exercise testing (CPX) parameters as predictors for RTW at discharge after CR. We analyzed data from a registry of 489 working-age patients (51.5 +/- A 6.9 years, 87.9 \% men) who had undergone inpatient CR predominantly after percutaneous coronary intervention (PCI 62.6 \%), coronary artery bypass graft (CABG 17.2 \%), or heart valve replacement (9.0 \%). Sociodemographic and clinical parameters, noninvasive cardiac diagnostic (2D echo, exercise ECG, 6MWT) and psychodiagnostic screening data, as well as CPX findings, were merged with RTW data from the German statutory pension insurance program and analyzed for prognostic ability. During a mean follow-up of 26.5 +/- A 11.9 months, 373 (76.3 \%) patients returned to work, 116 (23.7 \%) did not, and 60 (12.3 \%) retired. After adjustment for covariates, elective CABG (HR 0.68, 95 \% CI 0.47-0.98; p = 0.036) and work intensity (per level HR 0.83, 95 \% CI 0.73-0.93; p = 0.002) were negatively associated with the probability of RTW. Exercise capacity in CPX (in Watts) and the VE/VCO2-slope had independent prognostic significance for RTW. A higher work load increased (HR 1.17, 95 \% CI 1.02-1.35; p = 0.028) the probability of RTW, while a higher VE/VCO2 slope decreased (HR 0.85, 95 \% CI 0.76-0.96; p = 0.009) it. CPX also had prognostic value for retirement: the likelihood of retirement decreased with increasing exercise capacity (HR 0.50, 95 \% CI 0.30-0.82; p = 0.006).},

  abstract  = {Background Total hip or knee replacement is one of the most frequently performed surgical procedures. Physical rehabilitation following total hip or knee replacement is an essential part of the therapy to improve functional outcomes and quality of life. After discharge from inpatient rehabilitation, a subsequent postoperative exercise therapy is needed to maintain functional mobility. Telerehabilitation may be a potential innovative treatment approach. We aim to investigate the superiority of an interactive telerehabilitation intervention for patients after total hip or knee replacement, in comparison to usual care, regarding physical performance, functional mobility, quality of life and pain. Methods/design This is an open, randomized controlled, multicenter superiority study with two prospective arms. One hundred and ten eligible and consenting participants with total knee or hip replacement will be recruited at admission to subsequent inpatient rehabilitation. After comprehensive, 3-week, inpatient rehabilitation, the intervention group performs a 3-month, interactive, home-based exercise training with a telerehabilitation system. For this purpose, the physiotherapist creates an individual training plan out of 38 different strength and balance exercises which were implemented in the system. Data about the quality and frequency of training are transmitted to the physiotherapist for further adjustment. Communication between patient and physiotherapist is possible with the system. The control group receives voluntary, usual aftercare programs. Baseline assessments are investigated after discharge from rehabilitation; final assessments 3 months later. The primary outcome is the difference in improvement between intervention and control group in 6-minute walk distance after 3 months. Secondary outcomes include differences in the Timed Up and Go Test, the Five-Times-Sit-to-Stand Test, the Stair Ascend Test, the Short-Form 36, the Western Ontario and McMaster Universities Osteoarthritis Index, the International Physical Activity Questionnaire, and postural control as well as gait and kinematic parameters of the lower limbs. Baseline-adjusted analysis of covariance models will be used to test for group differences in the primary and secondary endpoints. Discussion We expect the intervention group to benefit from the interactive, home-based exercise training in many respects represented by the study endpoints. If successful, this approach could be used to enhance the access to aftercare programs, especially in structurally weak areas.},

Methods From 10/2013 to 07/2015, 344 patients with an elective TAVI were consecutively enrolled in this prospective multicentric cohort study. Before intervention, sociodemographic parameters, echocardiographic data, comorbidities, 6-min walk distance (6MWD), quality of life and frailty (score indexing activities of daily living [ADL], cognition, nutrition and mobility) were documented. Out of these, predictors for assignment to CR or GR after TAVI were identified using a multivariable regression model. Results After TAVI, 249 patients (80.7 ± 5.1 years, 59.0\% female) underwent CR (n = 198) or GR (n = 51). GR patients were older, less physically active and more often had a level of care, peripheral artery disease as well as a lower left ventricular ejection fraction. The groups also varied in 6MWD. Furthermore, individual components of frailty revealed prognostic impact: higher values in instrumental ADL reduced the probability for referral to GR (OR:0.49, p <  0.001), while an impaired mobility was positively associated with referral to GR (OR:3.97, p = 0.046). Clinical parameters like stroke (OR:0.19 of GR, p = 0.038) and the EuroSCORE (OR:1.04 of GR, p = 0.026) were also predictive. Conclusion Advanced age patients after TAVI referred to CR or GR differ in several parameters and seem to be different patient groups with specific needs, e.g. regarding activities of daily living and mobility.
