The Patellofemoral Pain Functional Performance Study
United Kingdom21 participantsStarted 2016-06
Plain-language summary
This study primarily aims to investigate arthrogenic muscle inhibition (AMI), an underlying mechanism in patellofemoral pain (PFP), which remain to date understudied. Although, studies have revealed that AMI needs to be eliminated before improvements in muscle strength can be achieved, to date quadriceps muscle inhibition in patients with PFP remains understudied. To date the influence of AMI on functional performance and the direct link to pain in patients with PFP remain unclear. This study aims to investigate the link between AMI to pain, functional performance and how an acute treatment can affect functional performance and pain.
