Accelerometer in stroke rehabilitation: A modern look at the assessment of physical activity

The importance of improving the quality of rehabilitation approaches is becoming particularly relevant, as the number of people with stroke-related disabilities is expected to grow due to advances in treatment that contribute to an increase in overall patient survival. Improving the understanding of physical activity during stroke rehabilitation is important, as physical activity is directly related to the recovery process of patients. It not only promotes recovery after a stroke, but also improves the state of the cardiovascular system, cognitive and motor functions, improves mood and increases survival. In this review, the authors analyzed the literature data on the use of accelerometry in the first stage of rehabilitation after stroke. Accelerometry quantifies physical activity by recording movements using accelerometers that measure acceleration along one or more axes. Accelerometry is a promising tool for improving the measurement of physical activity intensity during rehabilitation, although in practice its use remains limited. The use of the V3 and V3+ frameworks, which cover aspects of ergonomics testing, analytical and clinical validation, highlights the importance of a comprehensive assessment of accelerometry-based tools. The available data confirm the effectiveness of accelerometry in determining the intensity of physical activity, but also indicate an existing gap in the data of analytical and clinical studies.
