High‐resolution ultrasound (HRUS) is the imaging method of choice to visualize peripheral nerve size, structure, and biomechanical performance. The purpose of this study was to show and quantify the effects of active and passive wrist alignment on median nerve (MN) cross‐sectional area (CSA) along the forearm in a healthy population.
Methods
Sixteen healthy volunteers underwent HRUS of their dominant forearm (n = 16, 10 males, 6 females, 18–55 y of age). Median nerveʼs CSA was assessed at four defined areas on the forearm in relation to active and passive wrist alignment.
Results
Changes in wrist alignment were significantly associated with MN CSA (P |

Results
Changes in wrist alignment were significantly associated with MN CSA (P < .001), regardless if the wrist was moved actively or passively. MN CSA was lowest during passive extension of the wrist joint and highest during passive flexion of the wrist joint (range: 4.5–23.2 mm2).
Discussion
The elasticity of nerve tissue, the loose connective tissue between the fascicles, and the paraneurium allow peripheral nerves to adapt to longitudinal strain. HRUS enables the demonstration of significant median nerve CSA changes along the forearm during active and passive wrist movement in healthy volunteers.</description><identifier>ISSN: 0148-639X</identifier><identifier>EISSN: 1097-4598</identifier><identifier>DOI: 10.1002/mus.27403</identifier><identifier>PMID: 34423460</identifier><language>eng</language><publisher>Hoboken, USA: John Wiley & Sons, Inc</publisher><subject>Alignment ; Biomechanics ; Connective tissues ; Female ; Forearm ; Forearm - diagnostic imaging ; Forearm - innervation ; high‐resolution ultrasound ; Humans ; Male ; Median nerve ; Median Nerve - diagnostic imaging ; Median Nerve - physiology ; musculoskeletal ultrasound ; nerve cross‐sectional area ; Nervous tissues ; Peripheral nerves ; Ultrasonic imaging ; Ultrasonography - methods ; Ultrasound ; Wrist ; Wrist - diagnostic imaging ; Wrist - innervation ; Wrist Joint - diagnostic imaging</subject><ispartof>Muscle & nerve, 2021-11, Vol.64 (5), p.585-589</ispartof><rights>2021 Wiley Periodicals LLC.</rights><rights>2021 Wiley Periodicals, LLC.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><cites>FETCH-LOGICAL-c3133-b3ef77ccc0bb973ddab7c460bde05bbdd92b3e2b284b1a9ff27cf285dc88a4b43</cites><orcidid>0000-0003-2125-5208</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1002%2Fmus.27403$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1002%2Fmus.27403$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,778,782,1414,27911,27912,45561,45562</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/34423460$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Jengojan, Suren</creatorcontrib><creatorcontrib>Schellen, Christoph</creatorcontrib><creatorcontrib>Dovjak, Gregor</creatorcontrib><creatorcontrib>Schmidhammer, Robert</creatorcontrib><creatorcontrib>Weber, Michael</creatorcontrib><creatorcontrib>Kasprian, Gregor</creatorcontrib><creatorcontrib>Bodner, Gerd</creatorcontrib><title>High‐resolution ultrasound demonstrates in vivo effects of wrist movement on the median nerve along the forearm</title><title>Muscle & nerve</title><addtitle>Muscle Nerve</addtitle><description>Introduction/Aims
