As individual entities, knee-joint proprioception, landing kinematics, and knee muscles play important roles in functional joint stability. Preventing knee injuries during dynamic tasks requires accurate proprioceptive information and adequate muscular strength. Few investigators have evaluated the relationship between knee proprioception and strength and landing kinematics.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Objective<\/jats:title>\n                  <jats:p>To examine the relationship between knee proprioception and strength and landing kinematics.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Design<\/jats:title>\n                  <jats:p>Cross-sectional study.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Setting<\/jats:title>\n                  <jats:p>University research laboratory.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Patients or Other Participants<\/jats:title>\n                  <jats:p>Fifty physically active men (age = 26.4 \u00b1 5.8 years, height = 176.5 \u00b1 8.0 cm, mass = 79.8 \u00b1 16.6 kg).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Intervention(s)<\/jats:title>\n                  <jats:p>Three tests were performed. Knee conscious proprioception was evaluated via threshold to detect passive motion (TTDPM). Knee strength was evaluated with a dynamometer.
