Upper limb function is normal in patients with restless legs syndrome (Willis-Ekbom Disease)

Highlights • Restless legs syndrome, now called Willis-Ekbom Disease (RLS/WED), is a sensorimotor-related sleep disorder characterised by an abnormal urge to move. • The aim of the current study was to investigate upper limb function in RLS/WED patients using objective methodology. • RLS/WED patients manipulate objects in a normal manner and exhibit normal maximal pinch grip, tremor during movement, and movement speed and rhythmicity compared to age- and gender-matched healthy controls.
