The ankle brachial index (ABI) is a highly reliable and valid non-invasive test for diagnosing PAD. However, the traditional method has limitations. These include the time required, the need for Doppler equipment, the training of clinical staff, and patient discomfort. PWV refers to the speed at which an arterial pressure wave propagates along the arteries, and this speed is conditioned by arterial elasticity and stiffness. To address these limitations, we have developed a system that uses electrocardiogram (ECG) and photoplethysmography (PPG) signals to calculate pulse wave velocity (PWV). We propose determining the ABI based on this calculation. Validation was performed on 22 diabetic patients, and the results demonstrate the accuracy of the system, maintaining a margin of \u00b10.1 compared with the traditional method. This confirms the correlation between PWV and ABI and positions this technique as a promising alternative to overcome some of the limitations of the conventional method.<\/jats:p>","DOI":"10.3390\/bios14050251","type":"journal-article","created":{"date-parts":[[2024,5,16]],"date-time":"2024-05-16T06:44:31Z","timestamp":1715841871000},"page":"251","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Validation of a New Ankle Brachial Index Measurement System Using Pulse Wave Velocity"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0893-4647","authenticated-orcid":false,"given":"Juan David","family":"Romero-Ante","sequence":"first","affiliation":[{"name":"Neuroengineering Biomedical Group, Medical Robotics Unit, Institute of Bioengineering, Miguel Hern\u00e1ndez University of Elche, 03202 Elche, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4766-5723","authenticated-orcid":false,"given":"Esther","family":"Chicharro-Luna","sequence":"additional","affiliation":[{"name":"Department of Behavioural Sciences and Health, Nursing Area, Faculty of Medicine, Miguel Hern\u00e1ndez University of Elche, 03550 San Juan de Alicante, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0684-8534","authenticated-orcid":false,"given":"Juliana","family":"Manrique-C\u00f3rdoba","sequence":"additional","affiliation":[{"name":"Neuroengineering Biomedical Group, Medical Robotics Unit, Institute of Bioengineering, Miguel Hern\u00e1ndez University of Elche, 03202 Elche, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7902-1979","authenticated-orcid":false,"given":"Jos\u00e9 Mar\u00eda","family":"Vicente-Samper","sequence":"additional","affiliation":[{"name":"Neuroengineering Biomedical Group, Medical Robotics Unit, Institute of Bioengineering, Miguel Hern\u00e1ndez University of Elche, 03202 Elche, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9643-4548","authenticated-orcid":false,"given":"Alba","family":"Gracia-S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Department of Behavioural Sciences and Health, Nursing Area, Faculty of Medicine, Miguel Hern\u00e1ndez University of Elche, 03550 San Juan de Alicante, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3890-6225","authenticated-orcid":false,"given":"Jos\u00e9 Mar\u00eda","family":"Sabater-Navarro","sequence":"additional","affiliation":[{"name":"Neuroengineering Biomedical Group, Medical Robotics Unit, Institute of Bioengineering, Miguel Hern\u00e1ndez University of Elche, 03202 Elche, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,16]]},"reference":[{"key":"ref_1","unstructured":"(2024, March 01).
