“…Ashton-Miller et al (2001) conclude that central mechanisms could explain how training might modify proprioception. While several studies have reported positive effects of training on position sense (Kynsburg et al 2006;Lee and Lin 2008), Bernier and Perrin (1998) found improvements in position sense after an exercise program, but these improvements did not differ significantly from the control groups. Recently, in a critical evaluation of the available literature, Hupperets et al (2009a) concluded that the aforementioned effects on postural sway and joint position sense are not necessarily a consequence of the exercises, but may be due to a learning effect created by the repeated measurements.…”

Laboratory study using a repeated measures design. The aim of this study was to determine if ankle proprioception is targeted in exercises on unstable surfaces. Lateral ankle sprain (LAS) has recurrence rates over 70%, which are believed to be due to a reduced accuracy of proprioceptive signals from the ankle. Proprioceptive exercises in rehabilitation of LAS mostly consist of balancing activities on an unstable surface. The methods include 100 healthy adults stood barefoot on a solid surface and a foam pad over a force plate, with occluded vision.Mechanical vibration was used to stimulate proprioceptive output of muscle spindles of triceps surae and lumbar paraspinal musculature. Each trial lasted for 60 s; vibration was applied from the 15th till the 30th second. Changes in mean velocity and mean position of the center of pressure (CoP) as a result of muscle vibration were calculated. Results show that on foam, the effect of triceps surae vibration on mean CoP velocity was significantly smaller than on a solid surface, while for paraspinal musculature vibration the effect was bigger on foam than on solid surface. Similar effects were seen for mean CoP displacement as outcome. Exercises on unstable surfaces appear not to target peripheral ankle proprioception. Exercises on an unstable surface may challenge the capacity of the central nervous system to shift the weighting of sources of proprioceptive signals on balance.

“…In the present study, we believed that the lack of di erence between groups might be related to the characteristic of the single-leg test used. Ankle sprains are associated to fast movements, such as jumps, sprints and changes in direction 2,[4][5][6]8 ; however, the measures used herein, stabilization time and COP reposition in the support, are more accurate to di erentiate between individuals with and without stability 35,37 .…”

The soccer is one of the most popular sport modality around the world, with millions of practitioners of different levels, and thus, the incidence of injuries are expressive [1][2][3] . Among these injuries, the ankle sprain is the one that stands out 2, 4-5 .e ankle sprains are very common in soccer due to the demand of changes in direction performed with high velocities, after jumps and during the sprints itself 2,4,6 . ese rapid changes in direction or landing on irregular surfaces produces a large supination torque, causing the ankle to perform an excessive movement, overloading the joint and its structures, mainly the anterior talo-bular and the calcaneo-bular ligaments 7 .Repeated episodes of ankle sprains may negatively a ect the proprioception, which correspond to the perception of position and movement (i.e., synesthesia) of the body and its segments [8][9] . ese information are provided by mechanoreceptors in the muscles, tendons, skin, joint capsules and ligaments [10][11][12] .ese mechanoreceptors are sensitized by mechanics energy imposed to the joint and it is transmitted to the central nervous system by a erents impulses 13 . As a consequence to sprains, the a erent bers of the AbstractThe aim of the study was to compare the behavior of COP and passive ankle position sense in subjects with and without functional ankle instability. Took part in this study 20 subjects, divided into two groups: stable group (SG) and unstable group (UG). The COP evaluation was made with the single-leg balance test, with eyes opened and closed, on a force plate. The passive ankle position sense test was performed with subjects blindfolded. The ankle was positioned in a target angle (10° and 20°) and the dynamometer moved passively the ankle, then the subjects were instructed to push the stop button when they feel that the ankle was on the target angle, obtaining the absolute angular error (AAE). The following variables were obtained: total displacement (TD); antero-posterior (SDap) and medio-lateral standard deviation (SDml); total mean velocity (TMV); antero-posterior (MVap) and medio-lateral mean velocity (MVml). The comparison between the data with normal distribution was made with the Student's t test, while to the TD and SDml was used the Mann-Whitney test. The correlations were performed with the Pearson and Spearman tests. We adopted α < 0.05. We observed difference between AAE-10º (p < 0.05). Strong correlations were found between: AAE-10° and TMV (p < 0.01 r = -0.867); AAE-10° and MVap (p < 0.01 r = -0.854); AAE-10° and MVml (p < 0.01 r = -0.771), with eyes opened, and AAE-10° and TD (p < 0.05 r = -0.666); AAE-10º and SDap (p < 0.05 r = -0,685) and AAE-10° and MVml (p < 0.05 r= -0.766) with eyes closed. Ankle sprains harm the joint position sense without affecting the balance.

“…After the initial injury, overstretched/loosened ligaments and joint capsule may hamper the function of those mechanorecep tors in those structures. Some researchers reported prolonged peroneal muscle reflex latency in injured ankles [2628] , and others reported ankle position sense deficits in passive testing [8,12,29,30] and active testing protocols [12,15,29] . Moreover, it is indicated that the result of position sense testing (active matching of passive positioning) can be used to predict future ankle injuries [14,31] .…”

“…Balance/postural training is the most commonly employed rehabilitation treatment for individuals with ankle instability. The majority of the literature reports positive therapeutic effects of balance training (e.g., single limb standing, standing on an ankle disc/wobble board) [29,4555] . However, there are a few studies that disagree with its treatment effect [56,57] .…”

Lateral ankle sprain is a common orthopedic injury with a very high recurrence rate in athletes. After decades of research, it is still unclear what contributes to the high recurrence rate of ankle sprain, and what is the most effective intervention to reduce the incident of initial and recurrent injuries. In addition, clinicians often implement balance training as part of the rehabilitation protocol in hopes of enhancing the neuromuscular control and proprioception of the ankle joint. However, there is no consensus on whether the neuromuscular control and proprioception are compromised in unstable ankles. To reduce the prevalence of ankle sprains, the effectiveness of engaging balance training to enhance the neuromuscular control and proprioception of the ankle joint is also questionable. Core tip: Lateral ankle sprain is a common orthopedic injury with a high recurrence rate. However, there is no consensus on whether neuromuscular control and proprioception are compromised in unstable ankles, and whether proprioception training can reduce initial and recurrent ankle injuries. The purpose of this review is to discuss the etiology and intervention of initial and recurrent ankle sprains, focusing on the role of neuromuscular control and proprioception at the ankle joint. This review can provide clinicians the knowledge of constructing better examination protocols and rehabilitation programs for individuals with the unstable ankle.Hung Y.
