Feasibility of an Interactive Tablet-based Exercise Program for People With Chronical Diseases

Study Overview
=================
Brief Summary
-----------------
End Stage Renal Disease (ESRD) is a potential outcome of Chronic Kidney Disease (CKD) that requires renal replacement therapy in the form of dialysis or transplantation.Despite the encouraging benefits seen in PHD who exercised, they may be confronted with more barriers to start and maintain an exercise program than healthy persons, e.g. due to reduced accessibility of specialised physiotherapists. Telerehabilitation (TR), a subfield of telemedicine, may help to overcome some of the barriers to exercise regularly and connect PHD with specialised physiotherapists. The primary objective of this study is to determine feasibility of this TR exercise approach in preparation of a future RCT. Focus of the study is recruitment, attrition and adherence to the intervention, data collection methods and acceptability/satisfaction of the intervention. The secondary objectives are to evaluate potential impacts of this intervention approach on physical function and health-related disability and quality of life. The study intervention is an interactive tablet-based home exercise program. The program is called Dividat Fit and works interactive, meaning that the responsible specialised Physiotherapist (PT) supervises the training progression of her/his patient weekly and if necessary assists the patient via remote or through a visit at home.

Detailed Description
-----------------
End Stage Renal Disease (ESRD) is a potential outcome of Chronic Kidney Disease (CKD) that requires renal replacement therapy in the form of dialysis or transplantation. The prevalence rate of people undergoing dialysis is 296 of 1 Million. 90% of them receiving haemodialysis (HD). For haemodialytic therapy, patients need to receive dialyses 2-3 times a week in an outpatient hospital facility or a clinic lifelong or until kidney transplantation. A dialyses session last between 3 and 4 hours. Nowadays, the beneficial effects of exercise in people undergoing haemodialysis (PHD) are well accepted and there is evidence that they profit from an exercise program. Despite the encouraging benefits seen in PHD who exercised, they may be confronted with more barriers to start and maintain an exercise program than healthy persons, e.g. due to reduced accessibility of specialised physiotherapists. Telerehabilitation (TR), a subfield of telemedicine, may help to overcome some of the barriers to exercise regularly and connect PHD with specialised physiotherapists. TR is defined as the provision of rehabilitation services from a distance using telecommunication technologies as the delivery medium. This approach may optimize the timing, intensity and sequencing of interventions and provide opportunities for individuals to receive rehabilitation in their own social and professional environments from disease-specialised caregivers. An additional advantage of TR is the possibility to implement different persuasive technologies such as personalisation, self-monitoring, tailoring, goal setting, comparison and conditioning through positive and negative reinforcement in the development of exercise programmes. These technologies help to make exercise programmes more enjoyable and, therefore, enhance patients' motivation to exercise regularly. Furthermore, the importance of individual and social support has been emphasized in several reviews evaluating health behaviour change for example becoming more active. This kind of support can be integrated in the design of a TR program. To the best of our knowledge, there exist no TR programme especially designed for PHD. Therefore, the aim of this study is to evaluate feasibility of a tablet-based exercise program, called Dividat Fit for PHD. The study intervention is an interactive tablet-based home exercise program. The program is called Dividat Fit and works interactive, meaning that the responsible specialised Physiotherapist (PT) supervises the training progression of her/his patient weekly and if necessary assists the patient via remote or through a visit at home. During the first face-to-face session, the PT examines the patient, sets up an individually tailored physical exercise (PE) program with four to six exercises and practises these exercises with the patient. Before the patient will start with the 12-week home program, she/he receives a tablet-computer on which the physical exercises are programmed as well as an instruction how to use Dividat Fit. During the whole training program, the PT tele-monitors each patient by checking the training diary weekly and providing written feedback to the exercises and the comments, if applicable. If needed, the PT contacts the participants (per phone). 10-15 participants will be recruited. For feasibility studies, a sample size calculation is not possible. There are different rules of thumb for the sample size of feasibility studies. One general rule of thumbs recommends 12 participants for a feasibility study. Another recommendation is based on the estimated effect size: they recommend 15 or 10 patients for standardized effect sizes that are medium (0.5) or large (0.8), respectively.
