IT solutions for rehab are seen as an opportunity to provide effective support for patients’ recovery process in their in-home environment, based on instructions from health care professionals. However, what factors in the context affect the usefulness of such systems lie beyond the training process as such. In this research, we followed a co-design process, where the design of a support packaged for home rehab is based on standard products. Through group interviews with teams of home rehab staff, a broader view of the subject was sought. Group discussions involving the initial demonstration and testing of technology provided a wide spectrum of factors that the staff considered important for success, related to issues on both the organizational and the patient levels. These findings were analyzed for success factors in an attempt to reach an understanding of the rehab process context which will have an effect on the usefulness of the support system. As a result, a checklist of aspects on the process that need to be taken into account in the design of a rehab support system is presented and discussed. The results could be used both in the design of solutions and in the selection and implementation of support systems regarding how to improve the actual use of the systems.
