Two unique physical therapy interventions derived from research
in the area of orthopaedic surgery were performed
with reduced pain during the interventions in patients with
FFPS. They also resulted in clinically and statistically significant
pre- to post-intervention improvements in pain during
manual muscle testing and rectus femoris length testing in
addition to statistically significant pre- to post-intervention
increases in rectus femoris muscle length. The results of this
quasi-experimental study indicate the need for future experimental
study. Future study should include functional in addition
to impairment-based outcome measures, standardization
and blinding for the rectus femoris muscle length test
(should future researchers chose to again use this outcome
measure), a pilot study establishing reliability of outcome
measures collected by the therapist, younger subjects, and
the collection of longer-term outcome data.
