INTRODUCTION: The physical disability and the level of dependence for daily activities that follow a stroke requires validated and standardized instruments to measure objectively the functional status and the impact of interventions on prognosis. The Motor Activity Log (MAL-30) and Action Research Arm (ARA) scales possess these characteristics, currently being the most used in evaluation of the upper extremity. OBJECTIVE: TO analyze the psychometric properties and utility of MAL-30 and ARA as tools to assess the function of the paretic upper limb after stroke for the clinical practice and research. METHODS: We performed an observational, longitudinal design with clinimetric performance analysis, with a sample of 80 patients. Two measurements were made, at baseline (time 1) clinical and socio-demographic profile, MAL-30 and ARA was applied. One month later (time 2), MAL-30, ARA and Stroke Impact Scale (SIS 3.0) were applied. RESULTS: MAL-30 and ARA have adequate internal consistency and temporal stability. In addition, an appropriate construct validity by correlating significantly and in the expected direction between the two instruments and items of SIS 3.0, spasticity, pain, age, educational level and employment status. CONCLUSIONS: The evidence indicates that both MAL-30 and ARA have psychometric properties that make them ideal tools for assessing functional recovery in the paretic arm. However, it is necessary to consider some characteristics of each instrument before defining its clinical use and research properties. [ABSTRACT FROM AUTHOR]
