Since its introduction in the 1970s percutaneous treatment of lumbar disc herniation has been an attractive concept that has been the object of technical development and clinical application throughout the world. Little scientific evaluation of the efficacy and effectiveness of the procedure has been done. To estimate the success rates of automated(More)
Although previous studies have found automated percutaneous discectomy and epidural percutaneous discectomy to be less efficacious than conventional discectomy, these percutaneous procedures may be effective and cost-effective as a first surgical treatment for herniated lumbar disc. Percutaneous procedures for herniated lumbar disc continue to be performed(More)
BACKGROUND With the advent of magnetic resonance imaging, or MRI, clinicians and researchers have sophisticated techniques by which to assess the anatomy of the temporomandibular joint, or TMJ. Imaging is indicated when the results will affect the patient's care beyond that which can be gained from a complete clinical assessment. One of the primary(More)
Temporomandibular joint internal derangement (TMJ ID) is the most common intra-articular TM disorder and can progress from TMJ ID with reduction to TMJ ID without reduction. It is not known whether this anatomical progression is associated with increasing levels of mandibular dysfunction. The objective of this study was to determine whether the level of(More)
Men are considerably less likely to seek professional and nonprofessional help for mental disorders. Prior findings indicate that adherence to masculine norms contributes to stigma about internalizing disorders and help seeking. There are currently no empirically supported interventions for increasing help seeking in men with internalizing symptoms. To(More)
This study compared left- versus right-hand performance within healthy, right-handed, 8- or 9-yr.-old boys and girls on a finger-movement tracking task. 38 boys and 38 girls were randomly assigned to use either the left hand first and right hand second or vice versa in tracking a sine wave target with extension and flexion movements of the index finger.
