Establishing levels of arm-hand activities in stroke patients: the arm-hand-activities-scale (AHAS).

WHAT IT FOUND

The Arm-Hand-Activities-Scale (AHAS) is a quick, 5-category observational tool that reliably classifies arm function in stroke patients.

It correlates strongly with standard measures, is easy for clinicians and patients to understand, and captures what patients actually do in daily life rather than just their maximum capacity.

Key findings

01The AHAS shows strong correlation with established gold-standard measures like the Fugl-Meyer Assessment and the Action Research Arm Test, and is sensitive to change over 4 weeks of rehabilitation.

02The scale is highly comprehensible to various professionals and patients, with an average accuracy rate of 94.7% in understanding the categories.

03Inter-rater reliability is excellent for identifying patients with 'no activities' and 'fixing objects', and good for higher-level activities, supporting its use for consistent clinical grouping.

What it does not show

The scale is currently validated only for German-speaking populations, though English testing is underway. As an observational tool, it relies on subjective judgment and requires standardized procedures to minimize variability. The validation study included only patients with adequate cognitive and language abilities, so its utility in severe aphasia or cognitive impairment is untested. It is a categorical classification, not a continuous measurement, which may limit precision in detecting small changes.

Declared interests

The authors have no conflicts of interest to declare.

The easy way to misread this

Do not use AHAS as a substitute for detailed capacity assessments like the FMA or ARAT when precise motor metrics are needed. It measures observed performance in daily life, which can differ from maximum capacity, and its categories are subjective without standardized training.
