Reliability of assisted indentation in measuring lumbar spinal stiffness.
The reliability of manual methods to assess spinal stiffness is modest at best. In response, instrumentation has been developed which may be reliable, but is often difficult to use in clinical settings. The purpose of this study was to determine the intra-rater reliability of assisted indentation (AI), a smaller, less automated technique of measuring spinal stiffness in vivo. Twenty-three asymp...
متن کاملElectrophysiological Studies and Radiofrequency Ablations in Children and Adolescents with Arrhythmia
BACKGROUND Radiofrequency ablation is the standard non-pharmacological treatment for arrhythmias in pediatric patients. However, arrhythmias and their associated causes have particular features in this population. OBJECTIVE To analyze the epidemiological characteristics and findings of electrophysiological diagnostic studies and radiofrequency ablations in pediatric patients referred to the E...
متن کاملElectrogram-gated radiofrequency ablations with duty cycle power delivery negate effects of ablation catheter motion.
BACKGROUND Cardiac and respiratory movements cause catheter instability. Lateral catheter sliding over target endocardial surface can lead to poor tissue contact and unpredictable lesion formation. We describe a novel method of overcoming the effects of lateral catheter sliding movements using an electrogram-gated pulsed power ablation. METHODS AND RESULTS All ablations were performed on a th...
متن کاملA simple indentation device for measuring micrometer-scale tissue stiffness.
Mechanical properties of cells and extracellular matrices are critical determinants of function in contexts including oncogenic transformation, neuronal synapse formation, hepatic fibrosis and stem cell differentiation. The size and heterogeneity of biological specimens and the importance of measuring their mechanical properties under conditions that resemble their environments in vivo present ...
متن کاملUtility of intercostal nerve conventional thermal radiofrequency ablations in the injured worker after blunt trauma.
BACKGROUND Intercostal nerve blocks offer short-term therapeutic relief and serve as a diagnostic test for intercostal neuralgia. This original case report demonstrates the efficacy of radiofrequency ablations for long-term pain relief of intercostal neuralgia. To date, there have been no studies that demonstrate the efficacy of thermal conventional intercostal nerve radiofrequency ablations fo...
