Beyond Observation: Validating the Ecological Relevance of the Ad-AHA Stroke Using Sensor-Based Measures

After a stroke, many people experience difficulty using both hands together in daily life. Most rehabilitation assessments, however, only measure how the affected arm performs in one-handed tasks. This makes it difficult to understand how well people actually use their hands in real-world activities, which are usually bimanual. The Adult Assisting Hand Assessment - Stroke version (Ad-AHA Stroke) is a new clinical test that evaluates how the affected hand performs during two-handed tasks. While promising, it is still unknown whether the score on this test truly reflects how stroke survivors use their hands in daily life. This study aims to investigate this question by comparing Ad-AHA Stroke scores with real-life data on hand use, recorded over three days using wrist-worn sensors on both arms. By combining clinical and sensor-based measures, this study will help determine whether the Ad-AHA Stroke can accurately represent everyday bimanual performance after stroke.
