Physioter"],"abstract":"<jats:p>Introduction: The Cranio-Cervical Flexion Test (CCFT) is a validated clinical test used to evaluate deep cervical flexor muscle\u00a0function. A pressure biofeedback unit (PBU) has traditionally been the reference device. Recently, a new portable digital device\u00a0known as the Neuromuscular Cranio-cervical Device (NOD) has been developed as a potential alternative.Methods: In this cross-sectional concurrent validation study, 88 participants were recruited from four outpatient physiotherapy\u00a0practices, including individuals with current neck pain and individuals with a previous history of neck pain. All participants performed\u00a0the CCFT using both devices. The PBU was inflated to a baseline pressure of 20 mmHg, with the participant then performing\u00a0C-CF to increase the pressure in increments of 2 mmHg over five progressive stages, while the NOD was calibrated to\u00a0corresponding force targets. Agreement and concurrent validity between the devices were assessed, and C-CF range of motion\u00a0(ROM) was analyzed using linear mixed-effects models.Results: Agreement between CCFT performance scores obtained with the NOD and the PBU was 94.3%, with a very strong positive correlation (Spearman\u2019s \u03c1 = 0.930, p &lt; 0.001). The NOD measured slightly greater C-CF ROM than the PBU (mean difference 0.68\u00b0), with significant differences at lower CCFT stages that converged at higher stages of the test.Conclusion: These findings demonstrate strong concurrent validity between the NOD and the PBU, supporting the NOD as a\u00a0valid digital alternative for assessment of the CCFT.<\/jats:p>","DOI":"10.33393\/aop.2026.3947","type":"journal-article","created":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T06:43:02Z","timestamp":1788244982000},"page":"158-165","source":"Crossref","is-referenced-by-count":0,"title":["Concurrent validity of a novel digital dynamometer for assessing performance on the Cranio-Cervical Flexion Test"],"prefix":"10.33393","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8579-0686","authenticated-orcid":true,"given":"Marco","family":"Barbero","sequence":"first","affiliation":[{"name":"Rehabilitation Research Laboratory 2rLab, Department of Business Economics, Health and Social Care, University of Applied Sciences and Arts of Southern Switzerland, Manno - Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniele","family":"Lonati","sequence":"additional","affiliation":[{"name":"MedAction, Rapperswil-Jona - Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-9679-1087","authenticated-orcid":true,"given":"Marco","family":"Griseri","sequence":"additional","affiliation":[{"name":"Rehabilitation Research Laboratory 2rLab, Department of Business Economics, Health and Social Care, University of Applied Sciences and Arts of Southern Switzerland, Manno - Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1632-6684","authenticated-orcid":true,"given":"Corrado","family":"Cescon","sequence":"additional","affiliation":[{"name":"Rehabilitation Research Laboratory 2rLab, Department of Business Economics, Health and Social Care, University of Applied Sciences and Arts of Southern Switzerland, Manno - Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-6933-1811","authenticated-orcid":true,"given":"Alessandro","family":"Bonafine","sequence":"additional","affiliation":[{"name":"Bachelor of Science in Physiotherapy, Department of Business Economics, Health and Social Care, University of Applied Sciences and Arts of Southern Switzerland, Manno - Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tiziano","family":"Negrisolo","sequence":"additional","affiliation":[{"name":"Fisioterapia Kinesis, Mendrisio - Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emanuele","family":"Falzone","sequence":"additional","affiliation":[{"name":"Studio di fisioterapia di Emanuele Falzone, Arbedo-Castione - Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samuel","family":"Pedrucci","sequence":"additional","affiliation":[{"name":"Fisiorehab, Manno - Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4325-9576","authenticated-orcid":true,"given":"Erik","family":"Cattrysse","sequence":"additional","affiliation":[{"name":"Experimental Anatomy Research Group, Department of Physiotherapy and Human Anatomy, Faculty of Physical Education and Physiotherapy, Vrije Universiteit Brussel, Brussels - Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deborah","family":"Falla","sequence":"additional","affiliation":[{"name":"Centre of Precision Rehabilitation for Spinal Pain, School of Sport, Exercise and Rehabilitation Sciences, University of Birmingham, Birmingham - United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"18642","published-online":{"date-parts":[[2026,8,31]]},"reference":[{"key":"19040","doi-asserted-by":"crossref","unstructured":"Falla D, Jull G, Dall'Alba P, et al.
