Normative Data for an Instrumental Assessment of the Upper-Limb Functionality

Abstract EN

Upper-limb movement analysis is important to monitor objectively rehabilitation interventions, contributing to improving the overall treatments outcomes.

Simple, fast, easy-to-use, and applicable methods are required to allow routinely functional evaluation of patients with different pathologies and clinical conditions.

This paper describes the Reaching and Hand-to-Mouth Evaluation Method, a fast procedure to assess the upper-limb motor control and functional ability, providing a set of normative data from 42 healthy subjects of different ages, evaluated for both the dominant and the nondominant limb motor performance.

Sixteen of them were reevaluated after two weeks to perform test-retest reliability analysis.

Data were clustered into three subgroups of different ages to test the method sensitivity to motor control differences.

Experimental data show notable test-retest reliability in all tasks.

Data from older and younger subjects show significant differences in the measures related to the ability for coordination thus showing the high sensitivity of the method to motor control differences.

The presented method, provided with control data from healthy subjects, appears to be a suitable and reliable tool for the upper-limb functional assessment in the clinical environment.
