Abstract:	Introduction: Up to 75% of stroke survivors are affected by upper limb hemiparesis. To cope with these deficits those affected compensate with available motor strategies. Compensation movements are considered limiting factors for sensorimotor recovery after stroke. They may be beneficial in the short term to perform a task but lead to long-term problems such as increased muscle contractures. Therefore, there is an effort to detect and correct compensation strategies in rehabilitation after stroke. Telerehabilitation including technology-based services are an appropriate and effective way of providing therapeutic services. The presented project aims to summarise the evidence of existing technology-based teleassessments and to provide implications for practical and research use. A contribution will be made through the development of a tele-assessment of motor compensation, which will provide gold standards for the measurement of arm motor compensation after stroke. Methods: The first study is a systematic review on observational tele-assessments for clients after stroke. The literature search was conducted in the databases Embase, Medline, CINAHL, Cochrane, Scopus, Web of Science and IEEE. Studies looking at function-based or task-orientated assessments are assessed. In the second study we develop a webcam-based tele-assessment to detect motor compensation within a drinking task. Therefore, we include up to 50 patients with sensorimotor deficits after stroke who will perform up to 2000 repetitions of a drinking task. The technology is based on machine learning algorithms. We use kinematic metrics of movements, therapist visual assessments based on the data of webcam-based body key points (webcam and depth cameras) and sensors (IMUs). Results: The literature search resulted in 3318 hits which are currently being screened by two authors.The preliminary results of the development of the webcam-based tele-assessment show that the chosen set-up and data collection procedure work in the test run and are now ready to be used with participants after stroke. Discussion: The use of technology-based systems provides objective, reliable, valid, and cost-effective solutions of assessing the impact of stroke. With the literature review we will capture the state of research regarding objective teleassessments in stroke rehabilitation. The webcam-based assessment will take therapist-independent personalized training a step further. Conclusions: The research will contribute to the evidence for technology-based assessments in research and practice and provide standards for the detection of motor compensation and motor recovery after stroke.
