OBJECTIVE Previous studies have reported similar results of shoulder MRI versus arthroscopy for high-field-strength (1.5-T) and low-field-strength (0.2-T) units. We report our experience with the accuracy of high- versus low-field-strength units versus arthroscopy for detection of supraspinatus tendon tears and labral tears in the same patients. SUBJECTS AND METHODS. Three musculoskeletal radio...

Electrical stimulation has been used for thousands of years for a variety of purposes including muscle reeducation, muscle strength training and wound healing. However, because it has been used most commonly by individuals in money making schemes, it has been sometimes considered the domain of quacks and charlatans. But electrical stimulation can be a potent tool in the clinical setting if prop...

Microstructure, precipitation hardening response, and mechanical and physical properties of Cu-Cr-Ag alloy and Cu-Cr-Ag-Ce alloy have been investigated using transmission electron microscopy, scanning electron microscope, optical microscope, electrical conductivity analysis, and tensile test. The influence of element Ce on the matrix refinement, impurity removal, and precipitation in the Cu-Cr-...

OBJECTIVE The aim of this study was to examine the associations of computed tomography-based x-ray attenuation and paraspinal electrical impedance myography measures of trunk muscles with absolute and relative (normalized by body weight) trunk extension strength, independent of muscle cross-sectional area. DESIGN This is a cross-sectional study of mobility-limited community-dwelling older adu...

Neuromuscular Electrical Stimulation (NMES) is a form of electrical stimulation that uses the application of electric current through electrodes, leading to the depolarization of the motoneuron, thus eliciting a muscular contraction (stimulation over the motor threshold). Although its beneficial effects on strength training are widely recognized, some controversial aspects concerning the underl...

Experimental data up to 7.0 T show that the blood oxygenation level-dependent (BOLD) signal of functional magnetic resonance imaging (fMRI) increases with higher magnetic field strength. Although several studies at 11.7 T report higher BOLD signal compared with studies at 7.0 T, no direct comparison at these two field strengths has been performed under the exact same conditions. It therefore re...

The breakdown strength characteristic of Low Density Polyethylene films (LDPE) under DC voltage application and the effect of water absorption have been studied. Mainly, our experiment was investigated under two conditions; dry and heavy water absorption. Under DC ramp voltage, the result found that the breakdown strength under heavy water absorption has a lower value than dry condition. In ord...
