Factors Influencing Paretic Upper Limb Use during First 4 Weeks after Stroke: A Cross-Sectional Accelerometry Study

Abstract

Objective This study aimed to investigate factors related to paretic upper limb use within the first 4 wks after stroke. Design Sixty inpatients within 4 wks of first-time stroke were stratified by severity defined by Fugl-Meyer Upper Limb scores: severe = 0-22, moderate = 23-50, and mild = 51-66. All wore a wrist accelerometer on the paretic upper limb (24 hrs). Factors investigated were the following measures: upper limb motor impairment; mobility; balance; functional independence; sensory impairment; cognitive function; social factors; environmental restriction; and knowledge. Individual and multivariate quantile regression analyses were performed. Results Upper limb motor impairment, mob..
