Human Modelling

A cartoon of a person standing. The limb segments are shown in different colours, with the corresponding masses and inertias shown. These parameters can be estimated via allometric scaling or estimated using Dynamic Identification Modelling (DIM).

Everyone is unique. This can be seen in subtle variations in limb length, increased strength due to exercise, or limitations in mobility due to illness and injury. People change over the course of their lifetimes, leading to nuances in their performance. By tracking and understanding these nuances, it is possible to individualise clinical interventions, track intervention efficacy, and prescribe the design of assistive devices.
