Reliability of automatic vibratory equipment for ultrasonic strain measurement of the median nerve.

The objective of this study was to test the reliability of ultrasonic median nerve strain measurements using automatic vibratory equipment. Strain ratios of the median nerve in the carpal tunnel model and the reference coupler were measured at three different settings of the transducer: 0, +2 and +4 mm (+ = compressing the model down 2-4 mm initially… (More)
