Context:There is limited information on fatigue of the evertors on frontal plane joint position sense (JPS).Objective:To examine the effects of isokinetic concentric-eccentric fatigue of the evertors on frontal plane JPS of the ankle.Design:A 2 × 4 factorial design.Setting:Research Laboratory.Patients or Other Participants:40 male and female healthy subjects.Interventions:JPS was tested at 10° and 20° of inversion and 5° and 10° of eversion in a nonfatigued/fatigued condition. After fatigue of evertors was determined on an isokinetic device, post fatigue testing of JPS occurred.Main Outcome Measures:JPS absolute error (AE) for inversion and eversion.Results:Main effect for condition and angle were significant with pre/post fatigue. There were overestimation of angles postfatigue with AE greater at 20° of inversion (P = .003), followed by 10° of inversion (P < .001), 10° of eversion (P = .005), and 5° of eversion (P = .005).Conclusion:When the ankle evertors were fatigued, the AE for JPS was significantly higher at all test 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.

The present study investigated the effect of taping and the semi-rigid ankle brace on ankle joint position sense. Sixteen healthy women (20.8 ± 2.3 years old) actively placed the ankle in a target position. The experimental conditions were: 1) wearing no orthosis device, 2) using semi-rigid brace, and 3) wearing ankle taping. Absolute error (AE) and variable error (VE) were calculated to obtain the joint position sense. We found an interaction effect between condition and target angle at 15o of plantar flexion for the variable VE, which showed smaller errors during the use of taping and semi-rigid brace. In conclusion, the use of ankle joint orthoses, whether taping or semi-rigid brace, decrease the variability of the position sense at 15o of plantar flexion, potentially decreasing ankle sprains occurrence.

Context  Joint position sense (JPS) is a key neuromuscular factor for developing and maintaining control of muscles around a joint. It is important when performing specialized tasks, especially at the shoulder. No researchers have studied how Kinesio Tape (KT) application affects JPS. Objective  To investigate the effects of KT application and no tape on shoulder JPS at increasing shoulder elevations in athletes. Design  Cross-sectional study. Setting  University laboratory. Patients or Other Participants  A total of 27 healthy athletes who did not participate in overhead sports (age = 20.44 ± 1.05 years, height = 175.02 ± 11.67 cm, mass = 70.74 ± 9.65 kg) with no previous pathologic shoulder conditions volunteered for the study. All participants were from 1 university. Intervention(s)  Shoulder JPS was assessed at increasing elevations with and without KT application. Participants attempted to actively replicate 3 target positions with and without the KT and without visual guidance. Main Outcome Measure(s)  We examined absolute and variable repositioning errors at increasing shoulder-elevation levels with and without KT application. Results  Data revealed an interaction between tape and position for absolute error (F2,52 = 4.07, P = .02); simple effects revealed an increase in error, with KT demonstrating a 2.65° increase in error at 90° of elevation compared with no tape (t26 = 2.65, P = .01). The effect size was medium (ω2 = .135). Variable error showed no interaction of tape and position (F2,52 = .709, P = .50). Further analysis of simple effects was not needed. However, we still calculated the effect size and observed small effect sizes for tape (ω2 = .002), position (ω2 = .072), and tape by position (ω2 = .027). Conclusions  At 90° of elevation, shoulder JPS was impaired by the application of KT.

Introduction Proprioceptive assessments of the wrist inform clinical decision making. In wrist rehabilitation, joint position sense has emerged as one way of assessing conscious proprioception with varying methods and minimal psychometric analysis reported. The purpose of this study was to standardise the wrist joint position sense test method for clinical use and to determine its test–retest reliability in a healthy population. Methods Four wrist positions (20° and 45° flexion, 20° and 45° extension) were measured twice in a random order, by a single rater, using a universal goniometer on the same day. The absolute error in degrees between each position and reposition was calculated. For relative reliability analysis, the intraclass correlation coefficient (3,1) was calculated. For absolute reliability the standard error of the measurement was calculated and Bland–Altman plots visually inspected. Results Fifty-five healthy volunteers (mean age 31.1 SD±10.25 years) were assessed. The mean absolute error, summarised for all positions for test and retest, was 3.98°. The intraclass correlation coefficients were poor to fair (0.07–0.47), and standard error of the measurement was 2° (rounded) for all positions. The limits of agreement were fairly narrow, and the Bland–Altman plots showed random distribution of errors for each position, therefore the measurement error was clinically acceptable. Conclusions The active wrist joint position sense test using goniometry demonstrated poor to fair test–retest reliability and acceptable measurement error in healthy volunteers. The wrist joint position sense angle of 20° flexion was the most reliable.

This study evaluated knee joint position sense in the ACL-reconstructed and contralateral normal knees of 48 male and female subjects (M age 27.6 ± 6.9 yrs). Subjects were blindfolded and tested on their ability to actively reproduce five passively placed knee positions at 5° intervals between 35 and 15° of knee flexion. Mean algebraic target angle error and mean absolute error values were measured in degrees. The grand mean absolute error for the postsurgical knees at all positions was 5.4 ± 3.2°, compared with 5.2 ± 2.7° for the normal contralateral knees. There were no significant differences in knee joint position sense between the postsurgical and normal contralateral limbs at any of the five positions tested. Pivot shift, anterolateral rotatory instability, and Lachman test results were poorly correlated with knee joint position sense. The results suggest that if knee joint position sense was indeed disrupted by ACL injury and reconstructive surgery, related sensory mechanisms compensated for any proprioceptive loss prior to the minimum 2-yr postsurgical follow-up period employed in our study.

Context:There is limited information on the effects of different warm-up periods on proprioception and balance in the context of injury prevention.Objective:To determine the effects of warm-up exercises on knee proprioception and balance and to compare the effectiveness of warming up periods.Design:Pretest/posttest.Setting:Research laboratory.Participants:30 healthy subjects (19 women, 11 men; mean age 20.70 ± 0.99 years).Interventions:Exercise groups performed warm-up exercises (group 1, 5 minutes; group 2, 10 minutes). Joint Position Sense (JPS) was tested at 15°, 30°, and 60° knee flexion (KF) on a JPS device. Balance was measured using the Neurocom Balance Master System.Main Outcome Measures:JPS absolute error (AE) was measured at 15°, 30°, and 60° KF and postural control was measured.Results:After exercise, we found significant improvements for AE of JPSs of 30° right (R) KF, 15° left (L) KF, and 60° L KF in group 1. In group 2, AE of JPS values increased for all angles of both knees except 60° R KF. AE of JPS values of 15° R KF, 30° R KF, 15° L KF, 60° L KF were significantly different in group 2 compared with group 1. In balance measurements, there were significant improvements for standing on foam with eyes closed (EC) position, velocity and R-L unilateral stance EC in group 1. There were significant improvements for velocity, end point, maximum excursion, and L unilateral stance EC in group 2.Conclusions:Both warm-up periods have positive effects on knee proprioception and balance. The 10-minute warm-up exercise improved proprioception by a greater amount than the 5 minutes warm-up exercise.

Introduction: The evaluation of changes in joint position sense (JPS) of the knee may be crucial for the identification of disorders that could start during the development of patellofemoral pain syndrome (PFPS). Objective: To evaluate JPS of the knee in PFPS. Methods: Twenty nine women (15 healthy and 14 with PFPS) reproduced knee flexion angles of 45° and 60° during open kinetic chain exercises and of 45° during closed kinetic chain exercises. Results: The absolute error in the active reproduction of 45° in open kinetic chain exercises was significantly higher in the experimental group. There were significant differences in absolute and relative errors between the groups for active reproduction at 45° in open and closed kinetic chain exercises. Conclusions: This study suggests that PFPS alters JPS during active reproduction of the 45° angle in both open and closed kinetic chain exercises.
