The stiffness of the dominant lower limb vastus lateralis (VL), rectus femoris (RF) and patellar tendon (PT) was evaluated in 52 healthy participants (26.9 \u00b1 3.4 years) with two MyotonPRO protocols: the standard protocol (10 mechanical taps) and the short protocol (five mechanical taps). The myotonometry was performed at the midpoint of the length from the upper pole of the patella to the greater trochanter for the VL, and to the anterior superior iliac spine for the RF. The PT was evaluated 1 cm caudal from the inferior pole of the patella. Pearson\u2019s correlation coefficients were calculated to determine the relationships between protocols. The validity of the short protocol was evaluated with Student\u2019s t-test. High positive correlations were observed between the short and standard protocols in the stiffness of the VL (r = 0.959; p &lt; 0.001), the RF (r = 0.967; p &lt; 0.001) and the PT (r = 0.953; p &lt; 0.001) and no differences were found between both protocols in the stiffness assessment of the VL, RF and PT (p &gt; 0.05). Therefore, the five-compressions protocol is a valid protocol for the assessment of lower limb mechanical properties.<\/jats:p>","DOI":"10.3390\/ijerph192114425","type":"journal-article","created":{"date-parts":[[2022,11,4]],"date-time":"2022-11-04T03:28:10Z","timestamp":1667532490000},"page":"14425","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Five-Compressions Protocol as a Valid Myotonometric Method to Assess the Stiffness of the Lower Limbs: A Brief Report"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0476-066X","authenticated-orcid":false,"given":"Alfredo","family":"Bravo-S\u00e1nchez","sequence":"first","affiliation":[{"name":"Faculty of Health Sciences, Universidad Francisco de Vitoria, 28223 Pozuelo de Alarc\u00f3n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pablo","family":"Abi\u00e1n","sequence":"additional","affiliation":[{"name":"Faculty of Humanities and Social Sciences, Comillas Pontifical University, C.
