Use of wrist-worn accelerometers to quantify bilateral upper limb activity and asymmetry under free-living conditions in people with multiple sclerosis

Background: Although upper limb (UL) dysfunctions are quite common among people with Multiple Sclerosis (pwMS), there is a scarcity of information about actual UL usage under free-living conditions. The aim of the present study is to quantitatively assess ‘real-world’ activity time, intensity and possible asymmetry of use among dominant and non-dominant ULs in pwMS. Methods: Twenty-eight pwMS (20 women, 8 men, average EDSS 4.3) and 28 age- and...
