“…Clinical diagnosis was the reference standard in nine studies, 16,24,27,31–33,38–40 and electrophysiologic diagnosis was the reference standard in the rest. Almost all studies compared power Doppler ultrasound with at least one other form of ultrasound, whereas some compared it to electrodiagnostic studies, 7,8,11,13,20–23,25–27,29–39 magnetic resonance imaging, 25 patient-reported outcomes, 7,20,23,35 or other measures.…”

“…The majority of investigations were case-control, four were cohort studies, 20–23 and two were case-series design (Tables 1 and 2). 7,8,11,13,16,20–40 Patient selection was prospective in all but three studies. 20,24,29 Four were longitudinal studies lasting 3, 20 6, 7,35 and 36 months, 23 respectively.…”

“…Most studies used both grayscale and power Doppler ultrasound, whereas some used multiple ultrasonography settings to detect flow, including color Doppler, spectral Doppler, and superb microvascular imaging, either to confirm power Doppler signals 8,11,13,26,29,30,32,33,36,38 or compare ultrasonography techniques. 22,27,37 The majority of studies used electrodiagnostic studies for confirmation of diagnosis, stratification of patients by disease severity, or comparison with ultrasonographic results. Studies involving longitudinal follow-up evaluated power Doppler ultrasound at multiple time points, ranging from 1 week to 36 months after treatment.…”

Background: Power Doppler ultrasonography has been used as an adjunct in the diagnosis of peripheral nerve compression neuropathy. To better characterize its sensitivity and specificity, the authors performed a systematic review of its use in carpal and cubital tunnel syndrome diagnosis. Methods: The authors systematically reviewed published literature on the use of power Doppler ultrasound to diagnose peripheral compression neuropathy using Ovid MEDLINE, Embase.com, Scopus,

The current literature studied the median nerve (MN) at specific locations during joint motions. As only a few particular parts of the nerve are depicted, the relevant information available is limited. This experiment investigated the morphological and biomechanical properties of the MN. The effects of the shoulder and wrist motions on MN were explored as well. Eight young healthy female individuals were tested with two-dimensional ultrasound and shear wave elastography (SWE). The morphological and biomechanical properties were examined in limb position 1, with the wrist at the neutral position, the elbow extended at 180°, and the shoulder abducted at 60°. In addition, the experiment assessed the differences among the wrist, forearm, elbow, and upper arm with Friedman’s test and Bonferroni post hoc analysis. Two groups of limb positions were designed to explore the effects of shoulder movements (shoulder abducted at 90° and 120°) and wrist movements (wrist extended at 45° and flexed at 45°) on the thickness and Young’s modulus. Differences among the distributions of five limb positions were tested as well. The ICC3, 1 values for thickness and Young’s modulus were 0.976 and 0.996, respectively. There were differences among the MN thicknesses of four arm locations in limb position 1, while Young’s modulus was higher at the elbow and wrist than at the forearm and upper arm. Compared to limb position 1, only limb position 4 had an effect on MN thickness at the wrist. Both shoulder and wrist motions affected MN Young’s modulus, and the stiffness variations at typical locations all showed a downward trend proximally in all. The distributions of MN thickness and Young’s modulus showed fold line patterns but differed at the wrist and the pronator teres. The MN in the wrist is more susceptible to limb positions, and Young’s modulus is sensitive to nerve changes and is more promising for the early diagnosis of neuropathy.
