Quantitative assessment of sitting time in ambulant adults with Muscular Dystrophy.

<h4>Background</h4>Current investigations into physical behaviour in Muscular Dystrophy (MD) have focussed largely on physical activity (PA). Negative health behaviours such as sedentary behaviour (Physical Behaviour) and sitting time (Posture Classification) are widely recognised to neg...
