The effect of fatigue on knee position sense is not dependent upon the muscle group fatigued

Abstract

Muscle fatigue affects knee position sense, and the deleterious effect is not different depending upon the muscle group fatigued.

Validity and Reliability of a Digital Inclinometer to Assess Knee Joint-Position Sense in a Closed Kinetic Chain

“…This hinders provision of immediate feedback for athletes and coaches during field evaluation and slows the planning of training or rehabilitation sessions. 1,4,5 Based on the aforementioned arguments, the inclinometer is an affordable and portable instrument that provides a valid and reliable method, applicable in training sessions and even in competition, when exertion may lead to an injury event. Studies that evaluated the effects of fatigue on proprioception 6 reported impairments in the acuity of athletes during knee JPS tasks.…”

“…This target position was 50° of knee flexion in the dominant leg, which refers to the intermediate range of knee flexion, where mediation by muscle sensors in the detection of knee position predominates. 5 After 5 seconds, they were asked to return to the initial position (full knee extension). At a spoken "reposition" order, the subjects tried to reproduce the target joint angle as accurately as possible and maintain the estimated position for 3 seconds until a "return" order was given.…”

“…4 Proprioception can be impaired during a sports event due to fatigue from training sessions or the competition itself or as a consequence of previous injuries. 5 It seems that the deterioration of the muscle spindles modifies the proprioceptive information that is sent to the central nervous system, blunting motor control. 6 Several studies have analyzed the effects of fatigue induced by exercise or competition on knee JPS.…”

Factors Influencing Proprioception: What do They Reveal?

“…Fatigue is defined as an exercise-induced reduction in the ability of a muscle to generate force or power due to peripheral and/or central factors, related with an increase in perceived exertion, which can be defined as the intensity of subjective effort, strain, discomfort or fatigue sensation that one feels during exercise (Gandevia, 2001). The effects of exercise-induced muscle fatigue on joint proprioception have been extensively investigated in the last decades (Allen & Proske, 2006;Brockett, et al, 1997;Carpenter, et al, 1998;Forestier & Bonnetblanc, 2006;Forestier, Teasdale, & Nougier, 2002;Givoni, Pham, Allen, & Proske, 2007;Ju, Wang, & Cheng, 2010;Lattanzio, Petrella, Sproule, & Fowler, 1997;Lee, Liau, Cheng, Tan, & Shih, 2003;Miura, et al, 2004;Myers, Guskiewicz, Schneider, & Prentice, 1999;Paschalis, et al, 2008;Paschalis, et al, 2007;Ribeiro, Santos, Gonçalves, & Oliveira, 2008;Ribeiro, Venâncio, Quintas, & Oliveira, 2011;Saxton, et al, 1995;Skinner, et al, 1986;Torres, et al, 2010;Tripp, et al, 2004;Vila-Cha, et al, 2011;Walsh, Hesse, Morgan, & Proske, 2004) (Table 4). The majority of studies investigating the effects of exercise-induced fatigue on proprioception have been conducted in the knee joint.…”

The Validity and Reliability of Knee Proprioception Measurement Performed With Inclinometer in Different Positions

“…It is the basic element of the spontaneous control of movement, balance and joint stability. Therefore, it is necessary for the execution of walking and daily and sport activities 3 .…”
