We examined potential relationships between the stiffness values acquired from different methodologies. Twenty-six individuals simulated sideways falls. During trials, force-deformation data of the trochanteric soft tissue were recorded, then fitted to polynomial and exponential functions. Stiffness was determined as a slope of the tangent line at maximum deformation (\n K<\/jats:italic>\n \n s_1st<\/jats:italic>\n <\/jats:sub>\n , K<\/jats:italic>\n \n s_2nd<\/jats:italic>\n <\/jats:sub>\n , and K<\/jats:italic>\n \n s_exp<\/jats:italic>\n <\/jats:sub>\n ) and at 0.4\u00a0N (\n K<\/jats:italic>\n \n s_2nd_0.4\u00a0N<\/jats:italic>\n <\/jats:sub>\n , K<\/jats:italic>\n \n s_exp_0.4\u00a0N<\/jats:italic>\n <\/jats:sub>\n ). Similarly, force-deformation data of the pelvis were fitted exponentially to determine the pelvis stiffness at peak impact force (\n K<\/jats:italic>\n \n b<\/jats:italic>\n <\/jats:sub>\n ). We also used a clinical device to measure the trochanteric soft tissue stiffness (\n K<\/jats:italic>\n \n s_myoton<\/jats:italic>\n <\/jats:sub>\n ). Correlation and regression analyses were performed. The\n K<\/jats:italic>\n \n b<\/jats:italic>\n <\/jats:sub>\n was correlated with\n K<\/jats:italic>\n \n s_1st<\/jats:italic>\n <\/jats:sub>\n and\n K<\/jats:italic>\n \n s_2nd<\/jats:italic>\n <\/jats:sub>\n (\n P<\/jats:italic>\n \u2009<\u2009.05) and decreased 1.7 and 0.7\u00a0kN\/m for every 1\u00a0kN\/m increase in\n K<\/jats:italic>\n \n s_1st<\/jats:italic>\n <\/jats:sub>\n and\n K<\/jats:italic>\n \n s_2nd<\/jats:italic>\n <\/jats:sub>\n , respectively (\n R<\/jats:italic>\n 2<\/jats:sup>\n \u2009=\u2009.23 and\n R<\/jats:italic>\n 2<\/jats:sup>\n \u2009=\u2009.21), but no variables were correlated with the\n K<\/jats:italic>\n \n s_myoton<\/jats:italic>\n <\/jats:sub>\n (\n P<\/jats:italic>\n \u2009>\u2009.05). When normalized, however, both\n K<\/jats:italic>\n \n b<\/jats:italic>\n <\/jats:sub>\n and\n K<\/jats:italic>\n \n s_myoton<\/jats:italic>\n <\/jats:sub>\n were correlated with\n K<\/jats:italic>\n \n s_1st<\/jats:italic>\n <\/jats:sub>\n and\n K<\/jats:italic>\n \n s_2nd<\/jats:italic>\n <\/jats:sub>\n (\n P<\/jats:italic>\n \u2009<\u2009.05). These findings provide insights into hip impact dynamics, suggesting that trochanteric soft tissue stiffness measured with a clinical device may serve as a predictor of pelvis stiffness during falls.\n <\/jats:p>","DOI":"10.1123\/jab.2025-0071","type":"journal-article","created":{"date-parts":[[2025,10,28]],"date-time":"2025-10-28T10:15:58Z","timestamp":1761646558000},"page":"22-30","source":"Crossref","is-referenced-by-count":0,"title":["Correlations Between the Trochanteric Soft Tissue Stiffness and the Pelvis Stiffness During Sideways Falls"],"prefix":"10.1123","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5475-3196","authenticated-orcid":true,"given":"Kitaek","family":"Lim","sequence":"first","affiliation":[{"name":"Injury Prevention and Biomechanics Laboratory, Department of Physical Therapy, Yonsei University, Wonju, South Korea"},{"name":"Department of Physical Therapy, Yonsei University, Wouju, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8735-3794","authenticated-orcid":true,"given":"Seung Su","family":"Kim","sequence":"additional","affiliation":[{"name":"Injury Prevention and Biomechanics Laboratory, Department of Physical Therapy, Yonsei University, Wonju, South Korea"},{"name":"Department of Physical Therapy, Yonsei University, Wouju, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2554-8083","authenticated-orcid":true,"given":"Chung Hwi","family":"Yi","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Yonsei University, Wouju, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9699-768X","authenticated-orcid":true,"given":"Ohyun","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Yonsei University, Wouju, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3986-2030","authenticated-orcid":true,"given":"Hye-Seon","family":"Jeon","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Yonsei University, Wouju, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9931-2466","authenticated-orcid":true,"given":"Sung Hyun","family":"You","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Yonsei University, Wouju, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6623-3806","authenticated-orcid":true,"given":"Woochol Joseph","family":"Choi","sequence":"additional","affiliation":[{"name":"Injury Prevention and Biomechanics Laboratory, Department of Physical Therapy, Yonsei University, Wonju, South Korea"},{"name":"Department of Physical Therapy, Yonsei University, Wouju, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"7","key":"r1","series-title":"Osteoporos Int","doi-asserted-by":"publisher","first-page":"1067","DOI":"10.1007\/s00198-008-0571-9","article-title":"Effect of soft shell hip protectors on pressure distribution to the hip during sideways falls","volume":"19","author":"Laing AC","year":"2008","unstructured":"Laing AC, Robinovitch SN.
