This study supports the use of McConnell taping in patients with PFPS. There was a significant improvement in self-reported symptoms when taping was combined with exercise as opposed to exercises alone.
While there are several limitations of this study, such as a low sample size, and only limited details being provided regarding the VMO exercises, it does highlight the need for a multi-modal approach when treating patients with knee pain.
Taping has been disputed extensively over the years in terms of clinical effectiveness, but perhaps it could at the very least have contributed to a placebo effect that supported improvement in self-reported symptoms.
In any case, this article highlights the need for considering multiple (adjunctive) treatment strategies when addressing PFPS.
