Biomechanical Efficiency
The degree to which an orthotic device optimises a patient's movement patterns while minimising energy expenditure during ambulation.
Full Definition
Biomechanical efficiency refers to the extent to which an orthosis facilitates normal or near-normal movement with the least possible metabolic cost. Editors encounter this term in clinical outcome reports, orthotic device prescriptions, and rehabilitation literature. It is distinct from mechanical efficiency, which refers to the engineering properties of a device in isolation. Writers should not conflate this term with general fitness or exercise efficiency. When reviewing clinical copy, ensure the term is used in the context of device-assisted movement, not unaided gait.
Usage
Usage note: Do not use interchangeably with 'comfort' or 'fit'; the term has a specific biomechanical meaning related to energy expenditure and movement quality.
