Twenty young, healthy adults (mean age 26.5 \u00b1 4.1 years, 85% right-limb dominant) participated. Knee extensor and flexor strength were measured at 60\u00b0\u00b7s\u22121 and 240\u00b0\u00b7s\u22121. Proprioception was assessed by measuring passive joint position sense (JPS1: position recognition; JPS2: repositioning) and kinesthesia (threshold to detection of passive motion, TTDPM). Functional performance was evaluated using the single-leg hop test (SLH), triple-hop test (TH), and crossover hop test (COH). Symmetry was calculated using the limb symmetry index (LSI) as the ratio of non-dominant to dominant limb values. The results showed that THT (p = 0.011) and COH (p = 0.032) performance was superior on the dominant limb. A correlation analysis revealed strong positive correlations between hop test distances and knee extensor strength (r = 0.56\u20130.70, p &lt; 0.001). JPS symmetry was negatively correlated with hop test symmetry (JPS1: SLH, r = \u22120.53; THT, r = \u22120.49; COH, r = \u22120.70). The participants with poorer position sense on the non-dominant leg were 2.7 times more likely to show LSI &lt; 90% (p = 0.035). In conclusion, proprioception\u2014particularly joint position sense\u2014is associated with functional symmetry during dynamic tasks, highlighting the importance of proprioceptive assessments in rehabilitation and injury prevention.<\/jats:p>","DOI":"10.3390\/muscles4010003","type":"journal-article","created":{"date-parts":[[2025,1,21]],"date-time":"2025-01-21T04:19:51Z","timestamp":1737433191000},"page":"3","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["The Influence of Knee Proprioception and Strength on Lower-Limb Functional Symmetry in Healthy Adults"],"prefix":"10.3390","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7670-8791","authenticated-orcid":false,"given":"Joffrey","family":"Drigny","sequence":"first","affiliation":[{"name":"Department of Sports Medicine and Physical Medicine and Rehabilitation, CHU de Caen Normandie, Normandie Univ, 14000 Caen, France"},{"name":"INSERM, COMETE, Universit\u00e9 de Caen Normandie, 14000 Caen, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marine","family":"Rolland","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine and Physical Medicine and Rehabilitation, CHU de Caen Normandie, Normandie Univ, 14000 Caen, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antoine","family":"Gauthier","sequence":"additional","affiliation":[{"name":"INSERM, COMETE, Universit\u00e9 de Caen Normandie, 14000 Caen, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"101608","DOI":"10.1016\/j.rehab.2021.101608","article-title":"Assessing Knee Functionality: Systematic Review of Validated Outcome Measures","volume":"65","year":"2022","journal-title":"Ann.
