“…Furthermore, it was considered that the ACL has an important proprioceptive sense function and assists stability by inducing muscular reactions, and thus, protects the knee joint from traumatic injury. In addition to proprioception, ligaments supporting the knee joint and muscles around the knee also have major roles in the maintenance of knee stability [6,25,26]. The quadriceps muscle acts as a dynamic stabilizer of the knee joint, whereas the hamstring muscles primarily protect against anterior subluxation via the action of dynamic protagonists on the ACL [6,10,13].…”

Aim The purpose of this study was to assess the correlations between dynamic postural stability and muscle strength, anterior instability, and knee scores in anterior cruciate ligament (ACL) deWcient knees. Method We examined 40 male patients with ACL injury prior to surgery. Maximal torques of Xexors and extensors of the injured knee at 60 and 180°/s were evaluated using an isokinetic testing device. Anterior translations of the tibia were measured using a KT-2000 arthrometer, and dynamic postural stabilities were measured during singleleg stance using the Biodex Stability System (BSS). Knee statuses were evaluated using Lysholm and International Knee Documentation Committee (IKDC) knee scores. Correlations between dynamic postural stability and muscle strength, anterior instability, and knee scores were determined. Results SigniWcant correlations were found between maximal torques of the extensor of injured knees at 60 and 180°/s (r = ¡0.52, p = 0.048 and r = ¡0.46, p = 0.019, respectively) and dynamic postural stability, and maximal torques of Xexors of injured knees showed similar relations (r = ¡0.51, p = 0.0048 and r = ¡0.47, p = 0.016, respectively). Lysholm and IKDC knee scores were also found to be correlated with dynamic postural stability (r = ¡0.49, p = 0.001 and r = ¡0.52, p = 0.005, respectively). However, no correlation was found between grade of anterior translation measured using the KT-2000 arthrometer and dynamic postural stability (p = 1.0). Conclusion Dynamic postural stability determined using the BSS appears to be inXuenced by muscle strength, as determined by isokinetic testing, but not with grade of anterior translation measured using a KT-2000 arthrometer. Subjective knee scores appear to improve in parallel with dynamic postural stability.

“…Researchers have reported that loading of the ACL and other capsuloligamentous structures during tasks such as open kinetic chain knee extension exercises in the terminal 508 of motion leads to reflexive hamstrings activity. 16,17 The exact range of motion and load conditions required to elicit this response remain unclear. Consequently, we monitored tibiofemoral translation continuously during testing so that we could assess and account for an association between muscle activity patterns and tibiofemoral translation as our focus was voluntary muscle control, not reactive muscle activity.…”

The aim of this study was to investigate whether athletic males and females have differences in their quadriceps and hamstrings muscle control strategies. Twenty-four people (12 males, 12 females) active in level I activities volunteered to participate. The subjects' muscle control strategies were studied using electromyography and a target matching protocol that assesses one's ability to produce force with control. The degree of control exhibited in the subjects' quadriceps and hamstrings muscle activation strategies was evaluated by calculating specificity indices for each muscle using circular statistics. Females displayed significantly lower specificity than males in their vastus medialis (p < 0.001), rectus femoris (p ¼ 0.044), and lateral hamstrings (p ¼ 0.001) muscle activity patterns, but similar specificity in their vastus lateralis and medial hamstrings activity patterns. Females also used a significantly higher magnitude of vastus lateralis (p < 0.001) and vastus medialis (p < 0.001) muscle activity than males to achieve the same relative force level. These findings indicate athletic males and females have differences in their knee muscle control strategies. ß

“…Disturbances of peripheral sensation (e.g., diabetic neuropathy) do not inevitably result in joint abnormality. Nevertheless, knee mechanoreceptors may play a role in promoting stability by providing sensory feedback, which allows modulation of the activation of agonist muscles, or even the coactivation of antagonist muscles (8)(9)(10)(11)(12).…”

Objective. To test the hypotheses that 1) knee position sense declines with age; 2) patients with osteoarthritis (OA) have worse knee position sense than elderly controls; and 3) knee position sense is correlated with functional status.Methods. The threshold for detection of knee joint displacement was measured in 30 patients with bilateral knee OA (Kellgren/Lawrence grade 2 2 in both knees), 29 elderly controls (who met clinical and radiographic criteria for exclusion of OA), and 25 young controls. Range of motion, laxity, radiographic severity, and functional status were also assessed.Results. A moderate correlation was found between joint displacement detection threshold and age (r = 0.598 and r = 0.501 for the right knee and the left knee, respectively). The threshold was substantially and significantly different between the OA patients and the elderly controls. Proprioceptive impairment was associated with worse disease-specific functional status.Conclusion. Proprioception declines with age, and is further impaired in elderly patients with knee OA. Poor proprioception may contribute to functional impairment in knee OA.Osteoarthritis (OA) is the most common form of arthritis in humans, affecting 15.8 million Americans (1). The knee is the site of involvement most commonly associated with disability (2,3). The prevalence of knee O A increases with age (3). Several factors appear to be
