Abstract Recently, a home-based rehabilitation system for stroke survivors (Baptista et al. Comput. Meth. Prog. Biomed. 176:111– 120 2019), composed of two linked applications (one for the therapist and another one for the patient), has been introduced. The proposed system has been previously tested on healthy subjects. However, for a fair evaluation, it is necessary to carry out a clinical study considering stroke survivors. This work aims at evaluating the home-based rehabilitation system on 10 chronic post-stroke spastic patients. For this purpose, each patient carries out two exercises implying the motion of the spastic upper limb using the home-based rehabilitation system. The impact of the color-based 3D skeletal feedback, guiding the patients during the training, is studied. The Time Variable Replacement (TVR)-based average distance, as well as the average postural angle used in Baptista et al. (Comput. Meth. Prog. Biomed. 176:111–120 2019), are reported to compare the movement and the posture of the patient with and without showing the feedback proposals, respectively. Furthermore, three different questionnaires, specifically designed for this study, are used to evaluate the user experience of the therapist and the patients. Overall, the reported results suggest the relevance of the proposed system for home-based rehabilitation of stroke survivors. Keywords Rehabilitation · Stroke survivors · Computer vision
Introduction Due to the population aging, the number of stroke survivors in Europe is expected to grow by 25% in the next two decades [2]. Hence, an important involvement of the research community in proposing solutions to

enhance their quality of life has been observed. Indeed, stroke survivors are very often affected by motor impairments, directly impacting simple activities in their daily lives. To maintain and restore these activities, one of the key treatment is rehabilitation. Usually, the clinician prescribes a therapy to the patient in a rehabilitation center [3]. Thus, the patient is monitored and advised by experts in order to improve his functional movements without impairing his health and safety. However, due to the economical burden, this assisted rehabilitation is mainly prescribed for a limited period of time. Then, following this therap
