Objective:To compare the ankle-joint position-sense patterns of gymnasts and nongymnasts.Design:Proprioceptive ability was evaluated with active and passive angle-reproduction tests.Participants:40 subjects assigned to 2 groups: group 1 (n = 20), healthy subjects, and group 2 (n = 20), teenage female gymnasts.Measurements:Joint-position sense was actively measured with a Cybex NORM™ isokinetic dynamometer and passively with a proprioception-testing device.Results:A Mann-Whitney U test was used to compare the mean values of the gymnasts’ and controls’ ankles. Results revealed statistically significant differences (P < .05) between the 2 groups. No statistically significant difference between the dominant and nondominant ankles in the 2 groups was observed.Conclusions:The results suggest that extensive training might affect ankle-joint position sense, but genetics and natural selection could be the reason. It is thought that athletes are able to develop enhanced neurosensory pathways as a result of long-term training.

Category: Ankle Introduction/Purpose: Previous studies have described the damage of sensori-motor control in ankle sprain as being a possible cause of functional instability. The methods to demonstrate the functional instability, have included the postural balance test, peroneal muscle reaction time to sudden ankle inversion, peroneal nerve conduction velocity, and joint position sense of the ankle. On the other hand, isokinetic fatigue of ankle plantar flexion and dorsiflexion exhibits the correlation with postural instability. We hypothesize muscle fatigue around ankle joint causes abnormality of joint position sense, especially inversion at ankle joint, and it will be one of the causes of the ankle sprain. The aim of this study was to evaluate the inversion angle replication errors of before fatigue and after fatigue. Methods: 11 subjects were included in this study. The subjects were placed in a sitting position with the knee flexed at 70°. Each subject placed the foot on a goniometer footplate with the ankle at 20° planter flexion. Subjects were blindfolded to eliminate visual input and to facilitate concentration during testing. The foot was passively rotated internally at random to one of six positions (5°to 30°), always starting from 0°. The footplate was rotated manually to the index angle in approximately 1 s, and held in position for 5 s. Then the ankle was returned to the 0° position. After that, the subjects moved their ankle to match the previous test angle actively. The difference between the index angle and replication angle was measured. Ankles were enforced planter and dorsiflexion according to previous reports, and replication error was measured before and after fatigue. Results: The side-to-side difference of the replication errors was 1.9±1.7° in the before-fatigue group and 2.6±1.8° in the after-fatigue group. There was a statistically significant difference between both the groups (p<0.05). In each inversion angle, there were significant differences of the side-to-side differences of the replication errors at 5°and 10°inversion angles (0.8±0.9°, 1.5±1.4° in the before-fatigue group and 2.2±1.7°, 2.6±1.5° in the after-fatigue group respectively). Conclusion: This study revealed the deficit of joint position sense in ankle inversion induced by fatigue. Fatigue may be one of the risk factor of ankle sprain through the deficit of joint position sense in inversion angle during sports activity.

Ankle Bracing

The purpose of this study was to determine the proprioceptive effects of ankle bracing and taping. Proprioception was assessed in 26 subjects by evaluating ankle joint position sense, which was determined by the subjects' ability to actively reproduce a passively positioned joint angle. Testing was performed at positions of 30° of plantar flexion and 15° of inversion. Each subject underwent four trials at each test angle under three conditions: braced, taped, and control. For the plantar flexion test, both the braced condition and the taped condition significantly enhanced joint position sense when compared to the control condition. There was no significant difference between the braced and taped conditions. For the inversion test, the taped condition significantly enhanced joint position sense compared to the control condition. There was no significant difference between the braced and the control conditions or between the braced and the taped conditions. This study demonstrates that ankle bracing and taping improve joint position sense in the stable ankle.

Contraction Type

Context: Proprioception is an individual’s awareness of body position in 3-dimensional space. How proprioceptive acuity changes under varying conditions such as joint position, load, and concentric or eccentric contraction type is not well understood. In addition, a limitation of the variety of techniques to assess proprioception is the lack of clinically feasible methods to capture proprioceptive acuity. The purpose of this study was to implement a readily available instrument, a smartphone, in the clinical evaluation of knee active joint position sense and to determine how joint angle, joint loading, and quadriceps contraction type affect an individual’s active joint position sense. Design: Cross-over study. Methods: Twenty healthy, physically active university participants (10 women and 10 men: 21.4 [2.0] y; 1.73 [0.1] m; 70.9 [14.3] kg) were recruited. Individuals were included if they had no neurological disorder, no prior knee surgery, and no recent knee injury. The participants were given a verbal instruction to locate a target angle and then were tasked with reproducing the target angle without visual or verbal cues. An accelerometer application on a smartphone was used to assess the angle to the nearest tenth of a degree. Three variables, each with 2 levels, were analyzed in this study: load (weighted and unweighted), contraction type (eccentric and concentric), and joint position (20° and 70°). A repeated-measures analysis of variance was conducted to assess the within-subjects factors of load, contraction, and position. Results: A significant difference of 0.50° (0.19°) of greater error with eccentric versus concentric contraction (P = .02) type was identified. In addition, a significant interaction was found for contraction × position, with a mean increase in error of 0.98° (0.33°) at the 20° position when contracting eccentrically (P = .03). Conclusions: Contraction type, specifically eccentric contraction at 20°, showed significantly greater error than concentric contraction. This suggests that, during eccentric contractions of the quadriceps, there may be decreased proprioceptive sensitivity compared with concentric contractions.

Visualization Techniques

Assessment and enhancement of joint position sense is an inexact science at best. Anew method of evaluating and improving this sense using motion-tracking technology that incorporates computer visualization graphics was examined. Injured and healthy subjects were evaluated for their abilities to determine shoulder joint position, after abduction, in two tasks. The first was active reproduction of a passively placed angle. The second was visual reproduction of such an angle. A training protocol was added to determine the effectiveness of proprioceptive training in conjunction with 3-D visualization techniques. The primary findings were (a) a significant difference (p= .05) in the level of joint position sense in injured vs. healthy subjects; (b) significantly less accurate reproduction of larger shoulder abduction vs. the smaller movement in the active reproduction task; (c) significantly greater ability to accurately reproduce angles actively vs. visually; and (d) that proprioception training using 3-D visualization techniques significantly increased activeandvisual reproductions of passively placed angles.

Context: Clinicians require portable, valid, and cost-effective methods to monitor knee joint-position-sense (JPS) ability. Objective: To examine the criterion-related validity of image-capture JPS measures against an isokinetic-dynamometer (IKD) procedure. Design: Random crossover design providing a comparison of knee JPS measures from image capture and IKD procedures. Participants: 10 healthy participants, 5 female, age 28.0 ± 13.29 y, mass 60.3 ± 9.02 kg, height 1.65 ± 0.07 m, and 5 male, 29.6 ± 10.74 y, mass 73.6 ± 5.86 kg, height 1.75 ± 0.07 m. Main Outcome Measures: The dependent variables were absolute error scores (AES) provided by 2 knee directions (flexion and extension). The independent variables were the method (image capture and IKD). Results: There was no significant difference between clinical and IKD AED into knee-extension data (P = .263, r = 0.55). There was a significant difference between clinical and IKD AES into knee-flexion data (P = .016, r =.70). Conclusions: Analysis of photographic images to assess JPS measurements using knee flexion is valid against IKD techniques. However, photo-analysis measurements provided a lower error score using knee-extension data and thus may provide an optimal environment to produce maximal knee JPS acuity. Therefore, clinicians do not need expensive equipment to collect representative JPS ability.
