Studies show DJO products improve mechanics, ease patellofemoral pain

Research presented at the International Patellofemoral Research Retreat supports the use of two DonJoy Orthopedics products, the SERF femoral strap and the Tru-Pull Advance knee brace.

In 19 female patients with patellofemoral pain syndrome, investigators from the University of Southern California found that the SERF (Stability through External Rotation of the Femur) strap was associated with significant decreases in hip internal rotation, hip adduction and pain during dynamic weight-bearing tasks compared to a no-strap condition.

Researchers from the University of Central Lancashire in the U.K. compared the Tru-Pull brace with neutral taping and no intervention during a step-down task. The brace was associated with significant decreases in maximum pain and average pain, and significantly reduced range of motion in the coronal and transverse planes. The findings were consistent with those of a similar study performed in healthy subjects, which was published by the same group in the February 2008 issue of Gait & Posture.

The research retreat was held in Baltimore in late April (see “Patellofemoral pain takes turn in spotlight, page 19). The proceedings will be published later this year in the Journal of Orthopedic & Sports Physical Therapy.
