Summary
The Action Research Arm test (ARAT) and the upper extremity section of the Motor Assessment Scale (UE-MAS) show similar, moderate responsiveness in tracking upper extremity function recovery in stroke patients undergoing rehabilitation.
Area of Science:
- Rehabilitation medicine
- Neuroscience
- Clinical assessment
Background:
- Stroke frequently results in upper extremity motor deficits, impacting patient independence.
- Accurate assessment tools are crucial for monitoring recovery during rehabilitation.
Purpose of the Study:
- To compare the responsiveness of the Action Research Arm test (ARAT) and the upper extremity section of the Motor Assessment Scale (UE-MAS).
- To evaluate their effectiveness in assessing upper extremity function recovery in stroke inpatients.
Main Methods:
- Study included 48 stroke inpatients from a physical medicine and rehabilitation department.
- Patients were assessed at admission and discharge using ARAT and UE-MAS.
- Responsiveness was analyzed using effect size (d), Wilcoxon test, and Spearman's rho, with the Fugl-Meyer scale as an external criterion.
Main Results:
- Both ARAT and UE-MAS demonstrated moderate and similar responsiveness for total scores (ARAT: d=0.52, rho=0.66; UE-MAS: d=0.45, rho=0.7).
- Responsiveness indices for subscales were also comparable, ranging from small to moderate.
Conclusions:
- The Action Research Arm test (ARAT) and the upper extremity section of the Motor Assessment Scale (UE-MAS) are valuable tools for measuring upper extremity function recovery in stroke patients.
- Both instruments exhibit comparable responsiveness, supporting their use in clinical practice and research.
