Does Accelerometry at the Centre of Mass Accurately Predict the Gait Energy Expenditure in Patients with Hemiparesis?

Background: The aim of this study was to compare energy expenditure (EE) predicted by accelerometery (EEcc) with indirect calorimetry (EE) in individuals with hemiparesis.

Methods: Twenty-four participants (12 with stroke and 12 healthy controls) performed a six-minute walk test (6MWT) during which EE was measured using a portable indirect calorimetry system and EE was calculated using Bouten's equation (1993) with data from a three-axis accelerometer positioned between L3 and L4.

Results: The median EE was 9.
