“…Their sense of kinesthesia prior to fatigue exceeded not only that of controls from other studies but also ballet dancers, who have been shown to have lower thresholds of motion detection than normal (age-matched) controls (3). Previous studies have shown athletic training to have an effect on the appreciation of joint position (1,2). The results of this study, then, are in agreement with previous studies of joint kinesthesia in athletes (3).…”

This study was designed to test position sense of the knee joint before and after fatigue in order to determine whether muscle or capsular receptors are the primary sensors for joint position sense. Reproduction of passive positioning and detection of the onset of motion (kinesthesia) were employed to measure joint position sense. Eleven subjects underwent joint position sense measurement before and after a fatigue protocol. A significant worsening of reproduction of knee joint angle after fatigue was noted (p less than 0.05). Threshold (kinesthesia) showed no statistically significant change after fatigue. A significant correlation of reproduction measurements and threshold measurements prior to fatigue (p less than 0.01) demonstrated that the same neural mechanism is applicable in the rested state, but these variables did not correlate significantly after fatigue. There was a significant correlation between reproduction measurements before and after fatigue (p = 0.018), while no correlation was seen for the pre- and postfatigue threshold measurements, suggesting a change in the neural path after fatigue. Since both tests of joint position sense are affected by fatigue, we conclude that muscle receptors are a prominent, if not primary, determinant of joint position sense, and capsular receptors may have a secondary role. Reproduction ability is decreased, presumably through the loss of efficiency of muscle receptors. The threshold data suggest a change in the mechanism of appreciation after fatigue, possibly due to increased sensitivity of capsular receptors from muscle-fatigue-induced laxity.

“…Similarly, Sung You [82] found differences of 47.5% in the joint ankle reposition between young (median age: 22.2 years) and aged (median age: 73.1 years) subjects. Barrack et al [4] estimated this reduction in about 6.54°. Yan and Hui-Chan [81] showed that the joint detection threshold was 50% higher in older subjects (aged 57-77 years) than in younger subjects (aged 25-35 years) for both knee extension and flexion movements.…”

Throughout the human life span the functions of several physiological systems dramatically change, including proprioception. Impaired proprioception leads to less accurate detection of body position changes increasing the risk of fall, and to abnormal joint biomechanics during functional activities so, over a period of time, degenerative joint disease may result. Altered neuromuscular control of the lower limb and consequently poor balance resulting from changes in the proprioceptive function could be related to the high incidence of harmful falls that occur in old age subjects. There is evidence of proprioception deterioration with aging. Regular physical activity seems to be a beneficial strategy to preserve proprioception and prevent falls among older subjects. Some studies have demonstrated that the regular physical activity can attenuate age-related decline in proprioception. This paper reviews the evidence of age effects on joint proprioception. We will discuss the possible mechanisms behind these effects and the role of regular physical activity in the attenuation of age-related decline in proprioception.

“…This deficit could lead to slowed protective reflexes such that muscle contraction occurs too late to protect the joint (2,28). This could ultimately result in recurrent instability.…”
