Although diagnosis is supported by imaging tests, it has so far been based on clinical findings. Neurophysiological tests are not effective for providing an accurate diagnosis. The objective of this study was to analyze the efficacy of the ultrasound-guided near-nerve needle sensory technique (USG-NNNS) for the diagnosis of TTS Methods: The study population comprised 40 patients referred for a neurophysiological study owing to clinical suspicion of TTS. Routine neurophysiological tests were performed and compared with the results of USG-NNNS. Results: The diagnosis of TTS was achieved in 90% of cases. We found significant differences between lateral plantar sensory recordings with surface electrodes and USG-NNNS techniques for amplitude, nerve conduction velocity (NCV), and duration. As for the medial plantar sensory recordings, differences were found only for duration. No responses were obtained with surface electrode studies in 64.8% of cases. In addition, we observed normal sensory NCV with surface electrodes in 20 patients, although this decreased when the NNNS technique was used. Conclusions: This is the first report of the efficacy of the USG-NNNS technique for confirming the diagnosis of TTS.<\/jats:p>","DOI":"10.3390\/jcm10143065","type":"journal-article","created":{"date-parts":[[2021,7,12]],"date-time":"2021-07-12T00:23:36Z","timestamp":1626049416000},"page":"3065","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Ultrasound-Guided Near-Nerve Needle Sensory Technique for the Diagnosis of Tarsal Tunnel Syndrome"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3240-2234","authenticated-orcid":false,"given":"Lorena","family":"Vega-Zelaya","sequence":"first","affiliation":[{"name":"Avanfi Institute, Calle Donoso Cortes 80, 28015 Madrid, Spain"},{"name":"Clinical Neurophysiology, Hospital Universitario de La Princesa, C\/Diego de Le\u00f3n 62, 28006 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c1lvaro","family":"Iborra","sequence":"additional","affiliation":[{"name":"Avanfi Institute, Calle Donoso Cortes 80, 28015 Madrid, Spain"},{"name":"Unit for Ultrasound-Guided Surgery, Hospital Beata Mar\u00eda Ana, 28007 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5468-823X","authenticated-orcid":false,"given":"Manuel","family":"Villanueva","sequence":"additional","affiliation":[{"name":"Avanfi Institute, Calle Donoso Cortes 80, 28015 Madrid, Spain"},{"name":"Unit for Ultrasound-Guided Surgery, Hospital Beata Mar\u00eda Ana, 28007 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6870-8409","authenticated-orcid":false,"given":"Jes\u00fas","family":"Pastor","sequence":"additional","affiliation":[{"name":"Clinical Neurophysiology, Hospital Universitario de La Princesa, C\/Diego de Le\u00f3n 62, 28006 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Concepci\u00f3n","family":"Noriega","sequence":"additional","affiliation":[{"name":"Department of Nursery and Physiotherapy, Faculty of Medicine and Health Sciences, University of Alcal\u00e1, 28801 Alcal\u00e1 de Henares, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"275","DOI":"10.1016\/j.fcl.2011.01.008","article-title":"Tarsal Tunnel Syndrome","volume":"16","author":"Gould","year":"2011","journal-title":"Foot Ankle Clin."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"193","DOI":"10.1007\/BF00271447","article-title":"The proximal and distal tarsal tunnel syndromes.
