Musculoskeletal pain, e.g., osteoarthritis of the knee, is known as the most prevalent medical condition and the second-largest contributor to the global disability”. Recent studies reported that the incidence of knee osteoarthritis (KOA), which leads to a total knee replacement (TKR), is significantly increasing. It was proven that a personalized rehabilitation program might play an essential role in the patient’s adherence to the treatment plan. Hence, post-operative rehabilitation is frequently recommended after a TRK. In-person rehabilitation is considered as very resource demanding and challenging for the patient to attend the rehabilitation clinical regularly. Therefore, self-training at home for two weeks without communication between health professionals and patients is offered as standard post-TKR rehabilitation in Northern Denmark Region. As a result, several limitations were observed by the health professional in the presented solution, which they primarily are referring to lack up knowledge of the patient’s adherence to the treatment program.

The studies showed that telerehabilitation could be utilized as an alternative to the existing treatment program. Telerehabilitation programs were introduced to provide the rehabilitation services at a distance and overcome the common challenges in conventional treatments. Telerehabilitation programs were primarily aimed to improve the accessibility of the services and reduce the need for transportation. Time flexibility and better human resource management can be considered as the other advantages of a telerehabilitation program. The Cost-effectiveness and efficacy of telerehabilitation solutions were reported high, and very high user-satisfaction was achieved.

In line with recent achievements, this Ph.D. thesis focuses on introducing a personalized telerehabilitation program for the patients after TKR in Denmark. The project was conducted in three phases of the (1) evaluating the existing telerehabilitation solutions and technologies, (2) identifying the actual users' needs and challenges, designing and developing a telerehabilitation program accordingly, (3) evaluating the feasibility and usability of the telerehabilitation solution.

The investigations indicated that a sensor-based telerehabilitation program might benefit from all three aspects of a telerehabilitation solution. Whereas, video-based telerehabilitation programs might still offer some degrees of time restrictions. By examining the available sensor technologies for tracking the exercises, it was decided to employ the wearable motion sensors.

The design and development of the program were conducted using the participatory design method. Stakeholders' challenges and concerns were collected using qualitative data collection methods. Portability, Portability, User-friendliness, Flexibility, Comprehensiveness were identified as the main requirement of the program. Users were participated in two workshops and actively involved in designing and developing the telerehabilitation program. The preliminary evaluation revealed that the program facilitated the rehabilitation and improved the sense of security and confidence among the patients.

Twelve patients were recruited before the operation, assessing the feasibility of the usability of the program. Training, reporting, communication, and information materials services were presented. The patients used the telerehabilitation program for eight weeks. Nine patients successfully completed the treatment. A very high satisfaction rate was reported, and the results showed that users’ adherence to the program was high. The communication platform was frequently used, and patients stated that it successfully established communication between stakeholders. Participants reported a lower level of user-friendliness of the using sensors while performing the exercises. Pain level and knee score (Oxford Knee Score) were significantly improved.

The results disclosed the semi-offline sensor-based telerehabilitation program after knee operation is feasible, usable, and facilitated the treatment.
