Knee joint laxity affects muscle activation patterns in the healthy knee.
This study investigated the effects of anterior knee joint laxity on muscle activation patterns prior to and following a lower extremity perturbation. Participants were subjected to a forward and either internal (IR) or external (ER) rotation perturbation of the trunk and thigh on the weight-bearing shank. Pre-activity (%MVIC) before the perturbation, and reflex time (ms) and mean reflex amplit...
متن کاملReproducibility of instrumented knee joint laxity measurement in healthy subjects.
OBJECTIVE To determine the reproducibility of frontal plane knee joint laxity measurement through the assessment of intra- and inter-rater reliability coefficients and intra- and inter-rater agreement coefficients. METHODS Two raters independently assessed the laxity of the knee joint in the frontal plane by three repeated measurements. Fourteen days later the assessment was repeated. Complet...
متن کاملAssociations of knee muscle force, bone malalignment, and knee-joint laxity with osteoarthritis in elderly people
[Purpose] From the viewpoint of prevention of knee osteoarthritis, the aim of this study was to verify how muscle strength and joint laxity are related to knee osteoarthritis. [Subjects and Methods] The study subjects consisted of 90 community-dwelling elderly people aged more than 60 years (22 males, 68 females). Femorotibial angle alignment, knee joint laxity, knee extensors and flexor muscle...
متن کاملQuadriceps Muscle Fatigue and Knee Joint Position Sense in Healthy Men
Purpose: Proprioception is a part of the somatosensory system responsible for sending information to the central nervous system to monitor the status of various body parts relative to each another. One of the main causes of impaired proprioception is fatigue. In the following study, the effects of fatigue on quadriceps muscle and hence on knee proprioception in healthy subjects was studied.&nbs...
متن کاملRelationship between knee joint laxity and knee joint mechanics during the menstrual cycle.
BACKGROUND An increase in knee laxity during the menstrual cycle may increase the risk of anterior cruciate ligament injury. OBJECTIVE To investigate whether changing knee laxity during the menstrual cycle correlates with changing knee joint loads in a cutting manoeuvre. DESIGN Cross-sectional study. SETTING Laboratory testing. PARTICIPANTS 25 healthy women, with a normal menstrual cycl...
