In the previous study we have demonstrated that in healthy subjects
significant changes in coronal and transverse plane mechanics can be produced by
the application of a neutral patella taping technique and a patellar brace.
Recently it has also been identified that patients with patellofemoral pain
syndrome (PFPS) display alterations in gait in the coronal and transverse planes.
This study investigated the effect of patellar bracing and taping on
the three-dimensional mechanics of the knee of patellofemoral pain patients
during a step descent task. METHOD: Thirteen patients diagnosed with
patellofemoral pain syndrome performed a slow step descent. This was conducted
under three randomized conditions: (a) no intervention, (b) neutral patella
taping, (c) patellofemoral bracing. A 20cm step was constructed to accommodate an
AMTI force platform. Kinematic data were collected using a ten camera infra-red
Oqus motion analysis system. Reflective markers were placed on the foot, shank
and thigh using the Calibrated Anatomical System Technique (CAST). RESULTS: The
coronal plane knee range of motion was significantly reduced with taping
(P=0.031) and bracing (P=0.005). The transverse plane showed a significant
reduction in the knee range of motion with the brace compared to taping (P=0.032)
and no treatment (P=0.046). CONCLUSION: Patients suffering from patellofemoral
pain syndrome demonstrated improved coronal plane and torsional control of the
knee during slow step descent following the application of bracing and taping.
This study further reinforces the view that coronal and transverse plane mechanics should not be overlooked when studying patellofemoral pain.
