A recent study conducted by faculty members Dr. Kai-Yu Ho and Dr. Jing Nong Liang (both Physical Therapy), along with Doctor of Physical Therapy students Michael Carpio, John Donohue, and Jacob Kissman, investigates the link between knee pain and hip muscle activation.

Patellofemoral pain (PFP) — a common knee condition — has traditionally been attributed to weak hip muscles, leading to excessive inward knee movement during activities like walking and running. However, this research suggests that the brain’s control over these muscles may play a crucial role as well.

The study examined how effectively the brain activates the gluteus medius and gluteus maximus in individuals with and without PFP. Findings revealed that better activation of these hip muscles correlated with improved knee function and more stable movement patterns.

These results suggest that treatments aimed at enhancing neuromuscular control of the hip muscles could be beneficial for individuals with PFP, potentially improving knee stability and reducing pain.
