The use of tele-rehabilitation (TR) is a rapidly growing area within health care with the aim of dealing with the demographics changes of a growing elderly population and increasing number of patients with chronic conditions needing rehabilitation. Results from research indicate, that TR is equally as efficient as usual care. However, there is a need for more studies of high quality on the efficacy and cost-effectiveness of TR just as the long-term effects of TR have to be determined. In addition, there is a need for qualitative studies elucidating the patients' perspective of TR.
