PURPOSE AND METHOD In this literature review, relevant studies on electromyographic (EMG) onset timing of vastus medialis obliquus and vastus lateralis in people with and without patellofemoral pain syndrome (PFPS) were reviewed and discussed. CONCLUSION Studies had used diverse EMG signal processing and testing protocols, also only a half of their… (More)
We report the MRI and CT findings of an intracranial meningeal melanocytoma (IMM) arising from Meckel's cave and review the imaging characteristics of IMM. On CT, IMM constantly appear as well-circumscribed, isodense to slightly dense, extra-axial tumours with homogeneous contrast enhancement. This appearance is non-specific and similar to that of… (More)
Inflammatory myofibroblastic tumor (IMT) is a rare tumor with a variable natural history and biologic behavior, ranging from completely benign to malignant with fatal outcome. We report a case of benign IMT in the left nasal cavity with radiologic features mimicking angiofibroma. We also demonstrate the hypervascular nature of this disease on angiography… (More)
We report a case of Balò's concentric sclerosis. In the past, the diagnosis was usually made post mortem. In this case, we found that CT demonstrated only low-density lesions, but not their concentric pattern. However, MRI showed a striking feature, reminiscent of histopathology of Balò's concentric sclerosis, and played an important role in antemortem… (More)
An abnormal origin of the vertebral artery from the common carotid artery (VA-CC) may occur on the right or left side with different embryonic mechanisms. We describe a patient with a double developmental anomaly, a right VA-CC and a right aortic arch. The rotation of the aortic arch caused a "twist" of the embryonic mechanisms of VA-CC and misdirected the… (More)
We report a symptomatic case of unilateral hypoplasia of the internal carotid artery with an intercavernous anastomosis, a very rare developmental anomaly. The symptoms were caused by occlusion of the proximal middle cerebral artery which possibly related to the haemodynamic stress caused by the anomalous intercavernous anastomosis.
Concomitant hip adduction during squatting has long been advocated as a rehabilitative method to preferentially activate the VMO in persons with patellofemoral pain. This practice however has been based on research using surface electrodes which are prone to crosstalk from neighboring muscles (i.e., adductor magnus). This study sought to determine whether… (More)
