A study to assess the feasibility of a 3D Dynamic Imaging System in quantifying facial dysfunction

Facial weakness is common after stroke and can cause distress and embarrassment, as well as interfering with speech and swallowing. Currently we lack any evidence based interventions to treat facial weakness, possibly due to the lack of a robust measure. Dynamic 3D optical scanning is a new technology that measures symmetry of the face. It may allow small changes in facial symmetry to be measured accurately, thus detecting the effects of treatments, and rehabilitation.
