Figure 1From: The use of muscle strength assessed with handheld dynamometers as a non-invasive biological marker in myotonic dystrophy type 1 patients: a multicenter study The maximum isometric muscle strength of the ankle evertors (A) and dorsiflexors (B and C) was assessed with a Chatillon push-pull hand-held dynamometer. The positioning of the subject was standardised ensuring that «gravity eliminated» positions were used for each muscle group.Back to article page
