Simultaneous assessment of posture and limb movements (e.g., periodic leg movements) with calibrated multiple accelerometry

Abstract

This study describes new applications for the method of calibrated multiple accelerometry, which detects posture and distinct motion patterns, and limb movements continuously. The aim of our study was to evaluate this assessment technique in terms of its suitability for exploring the relationships between pathological limb movement activity (e.g., periodic leg movements) and posture. The new method proved to be appropriate for the simultaneous assessment of pathological leg jerks and posture and provided a means to revealing possible relations. Generally, our study demonstrates the application of this (ambulatory) assessment technique in the field of sleep and neurological disorders.
