Summary

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.

Detailed description

This is a single-center, cross-sectional observational study designed to examine the relationship between Ad-AHA Stroke scores and real-life bimanual hand use derived from accelerometry data in chronic stroke survivors.

Conditions

• Stroke
• Upper Limb Motor Impairment
• Bimanual Function

Interventions

Type	Name	Description
OTHER	Sensor-based monitoring and clinical assessment	Participants will complete the Ad-AHA Stroke assessment and wear bilateral wrist accelerometers for 3 days to measure real-life bimanual activity. No treatment or experimental intervention will be administered.
