Introduction: Telerehabilitation programmes have been attracting increasing attention as a potential alternative to conventional rehabilitation. Video conferencing can facilitate communication between healthcare professionals and patients. However, in certain cases, video conferencing may face practical limitations. As an alternative to real-time conferencing, sensor-based technologies can transmit the acquired data to healthcare providers. This study aimed to design and develop a sensor-based telerehabilitation programme and to outline the corresponding requirements for such a system., Development: The development of the sensor-based telerehabilitation programme was carried out based on user needs. The programme includes a portable platform for the patient as well as a web-based platform for the healthcare professional, thus allowing for an individualised rehabilitation programme. Communication, training, reporting, and information services were provided for the patients. Moreover, the portability and usability of the programme were enhanced by utilising the system in offline mode as well., Application: The programme is currently being tested in the North Denmark Region to assess the feasibility and acceptance of a telerehabilitation programme as an alternative solution to the self-training programme for patients who have been discharged from knee surgery. The preliminary results of our assessment showed a high level of acceptance among the users., Discussion: In this study, a semi-online sensor-based telerehabilitation programme was tested. It is argued that a similar sensor-based telerehabilitation programme can be utilised as an alternative solution for self-training rehabilitation in the future; however; further studies and development are required to ensure the quality and reliability of sensor-based services., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Background: Knee osteoarthritis (KOA) is a prevalent degenerative disease in older adults. Treatment strategies, including insoles, focus on reducing pain and physical disability. In medial KOA, insoles have been studied extensively with conflicting results, possibly due to heterogeneity in outcome measures and the intervention. We sought to investigate the effect of custom-made laterally wedged insoles on pain, function, and quality of life in patients with medial KOA., Methods: Fifty-one consecutive patients with medial KOA were prescribed custom-made insoles with arch support and a 5.0° to 8.7° lateral wedge. At follow-up, 42 of the 51 participants (22 men; mean age, 63 years; mean Kellgren-Lawrence, 3.4) participated. Retrospectively, participants were asked to rate the pain intensity in their affected knee before and after the intervention measured on a visual analog scale after 30 min of physical activity (primary outcome), at rest, at night, and after 50 m of walking. Additionally, they completed the Oxford Knee Score and the EQ-5D. The paired-samples t test was applied in the statistics., Results: The visual analog scale score after 30 min of physical activity was significantly reduced after the intervention (mean, 3.3 cm; 95% confidence interval, 2.1-4.5 cm; P < .001). The same significant changes were found in all of the secondary outcomes., Conclusions: There was a significant reduction in pain and improvements in function and quality of life with custom-made laterally wedged insoles with arch support in older adults with mild-to-severe medial KOA. The customization of laterally wedged insoles may be essential for the effect in medial KOA.
