Statistical modelling of Upper Limb Functional Ability using Motion Data: Validity Study

The objective of this study is to estimate the crosssectional and longitudinal validity (sensitivity to change) of a novel algorithm as a new measure to assess upper-limb functional ability in stroke survivors. This algorithm models functional ability by mapping an array of kinematic variables extracted from the analysis of movements made by patients while playing bespoke, professionally-written action video games to the CAHAI10 (Chedoke Arm and Hand Activity Inventory). A second aim of the research is to determine how the output from the model compares with existing measures of functional ability to distinguish change in patients in the acute/chronic stages of their recovery.
