While the reliability and validity of the K-force grip dynamometer have been established, its responsiveness remains unknown. This study evaluated the responsiveness of handgrip strength measured with the K-force grip dynamometer in intensive care unit-acquired weakness patients. \nMethods: In this prospective longitudinal study, intensive care unit-acquired weakness patients were assessed at baseline and after 1 week. Responsiveness was examined using effect sizes and standardized response means. The Medical Research Council sum score was included as a clinical comparator of global measure strength. Changes over time were analysed using Wilcoxon signed-rank tests.\nResults: Thirty-six patients were included. Dominant handgrip strength increased from 2650 g to 3450 g, with an effect size of r\u2009=\u20090.86 and standardized response means of 0.77 (p &lt; 0.001). Non-dominant handgrip strength increased from 2,700 g to 3,783 g, with an effect size of r\u2009=\u20090.90 and SRM of 0.70 (p &lt; 0.001). Medical Research Council sum score increased from 26.5 to 30.0 (p &lt; 0.001).\nConclusion: The K-force grip dynamometer demonstrated strong responsiveness in patients with intensive care unit-acquired weakness, supporting its use for detecting short-term changes in handgrip strength in critically ill patients.<\/jats:p>","DOI":"10.2340\/jrm.v58.46235","type":"journal-article","created":{"date-parts":[[2026,9,28]],"date-time":"2026-09-28T06:38:28Z","timestamp":1790577508000},"page":"jrm46235","source":"Crossref","is-referenced-by-count":0,"title":["Responsiveness of the K-Force Grip Dynamometer in patients with ICU-acquired weakness: a prospective longitudinal study"],"prefix":"10.2340","volume":"58","author":[{"given":"Ingrid D.","family":"Van Iperen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marleen","family":"Flim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter E.","family":"Spronk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1183","published-online":{"date-parts":[[2026,9,28]]},"reference":[{"key":"169401","doi-asserted-by":"crossref","unstructured":"Hiser SL, Casey K, Nydahl P, Hodgson CL, Needham DM.
