Nerve enlargement after cold exposure: A pilot study with ultrasound imaging

Abstract

These preliminary results revealed that cold exposure may cause acute nerve swelling. Further studies with larger samples will be necessary to confirm our findings, to correlate them with electrophysiological data, and to explore when/how the nerve edema resolves.

Difference in normal values of median nerve cross‐sectional area between dutch and indian subjects

“…A recent preliminary study showed that cold exposure may cause swelling of the median nerve at the carpal tunnel inlet. 10 The average temperature in The Netherlands is much lower than in India. We did not measure body temperature in this study.…”

“…Perhaps this finding could be explained by differences in arm exercise, labor, race, or environmental factors. A recent preliminary study showed that cold exposure may cause swelling of the median nerve at the carpal tunnel inlet . The average temperature in The Netherlands is much lower than in India.…”

Ultrasound in the diagnosis of peripheral neuropathy: structure meets function in the neuromuscular clinic

“…It is worthwhile noting that some studies have demonstrated that nerve size may be influenced by age, gender, body mass index and height 15 19. Temperature of the limb may also influence nerve calibre 22. As such, it is recommended that comparison groups in studies of nerve US are matched for those subject characteristics and standardised environmental conditions are employed during the study.…”

Ultrasound Elastography of the Median Nerve in Patients With Acromegaly: A Case‐Control Study

“…Hands were supported to be able to maintain a position of forearm supination, elbow flexion, and wrist extension in accordance with the technique. The cross‐sectional area was measured by the direct tracing method, with an electronic caliper from the inner border of the perineural echogenic rim from the swollen area just proximal to the entrapment area (Figure ) . The mean of 3 consecutive measurements was considered for statistical analyses.…”
