OBJECTIVE The purpose of this study was to determine if kinematic CT can be applied to the patellofemoral joint using current slip-ring CT scanner design in patients with anterior knee pain and thus a suspected patellar tracking disorder. SUBJECTS AND METHODS Twenty knees in 18 patients with anterior knee pain were evaluated with kinematic CT. A single(More)
BACKGROUND Iliotibial band friction syndrome (ITBFS) is an overuse injury causing lateral knee pain. There is evidence that the pathological lesion is in fact an inflamed bursa underlying the iliotibial band (ITB) rather than an inflamed ITB itself. HYPOTHESIS Resection of the bursa underlying the ITB in ITBFS patients will relieve their pain and allow(More)
The purposes of this study were to: 1) assess whole body center of mass (CM) motion in the frontal, sagittal, and transverse planes; 2) compare CM displacement with center of pressure (CP); and, 3) further define the stance and swing subphases of stair ascent (SA) and stair descent (SD) based on critical CM, CP, and ground reaction force (GRF) events. SA(More)
This is the second part of a two-part comprehensive review of lateral ankle sprains. In the first part of our review, we discussed the etiology, natural history, pathoanatomy, mechanism of injury, histopathogenesis of healing, and diagnostic approach to acute and chronic lateral ligamentous ankle injuries. Conservative intervention and treatment of grade(More)
It has been suggested that visual analysis of isokinetic quadriceps femoris muscle torque curve (TC) shapes may have potential use in the diagnosis and prognosis of knee pathologies. The primary purpose of this pilot study was to develop a method for analyzing the shape of an isokinetic TC. Our method normalizes and averages the TC, and then uses(More)
In the adult case presented, inhibitory casting proved successful in decreasing the positive support reaction. When casting was discontinued, the positive reaction returned. To provide a long-term solution for this problem, a polypropylene tone-inhibiting AFO was fabricated. It incorporated the same principles as the casts. The success achieved with casting(More)
Partially funded through a grant from the Children's Hospital Los Angeles, School of Physical Therapy Alumni Association. The main purposes of this study were to determine the reliability of an isokinetic, inversion/eversion torque test with and without range of motion targets, as well as to assess the effects of a plantarflexion position and of limb(More)
