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.

Context Foam-rolling exercises are frequently included in warmups due to their benefits for increasing range of motion (ROM). However, their effects on proprioception and vertical jump have not been analyzed and therefore remain unclear. Moreover, the effects of performing practical-duration foam-rolling exercises after typical warmup exercises such as jogging are unknown. Objective To analyze the effects of jogging and practical-duration foam-rolling exercises on the ROM, knee proprioception, and vertical jump of athletes. Design Randomized controlled study. Setting Sports laboratory and university track. Patients or Other Participants Thirty athletes were randomly classified into an experimental group (EG) or control group (CG). Intervention(s) The EG performed 8-minute jogging and foam-rolling exercises. The CG performed 8-minute jogging. Main Outcome Measure(s) Knee flexion, hip extension, active knee extension, ankle dorsiflexion (ADF), knee-joint position sense, and countermovement jump (CMJ) were evaluated before the intervention (baseline), after (post 0 min), and 10 minutes later. Results The EG exhibited higher values for ADF and CMJ at post 0 min (ADF: P < .001, d = 0.88; CMJ: P < .001, d = 0.52) and 10 minutes later (ADF: P = .014, d = 0.41; CMJ: P = .006, d = 0.22) compared with baseline. Although the CG also showed increased CMJ at post 0 min (P = .044, d = 0.21), the EG demonstrated a greater increase (P = .021, d = 0.97). No differences were found in the remaining ROM variables (knee flexion, hip extension, active knee extension: P values > .05). For knee-joint position sense, no differences were found (P > .05). Conclusions Combining jogging and practical-duration foam rolling may increase ADF and CMJ without affecting knee proprioception and hip or knee ROM. Jogging by itself may slightly increase ADF and CMJ, but the results were better and were maintained after 10 minutes when foam rolling was added.

Context: Knee joint-position sense (JPS) plays a critical role in controlled and stable joint movement. Poor ability to sense position of the knee can therefore increase risk of injury. There is no agreed consensus on JPS measurement techniques and a lack of reliability statistics on methods. Objective: To identify the most reliable knee JPS measurement technique using image capture. Design: Interexaminer, intraexaminer, and test-retest reliability of knee JPS measurements. Setting: Biomechanics laboratory. Participants: 10 asymptomatic participants. Interventions: None. Main Outcome Measures: Relative and absolute error scores of knee JPS in 3 conditions (sitting, prone, active) through 3 ranges of movement (10-30°, 30-60°, 60-90°), into 2 directions (flexion and extension) using both legs (dominant and nondominant) collected during 15 trials and repeated 7 d after the first data collection. Results: Statistical analysis by intraclass correlations revealed excellent interexaminer reliability between researchers (.98) and intraexaminer reliability within 1 researcher (.96). Test-retest reliability was highest in the sitting condition from a starting angle of 0°, target angle through 60-90° of flexion, using the dominant leg and absolute-error-score variables (ICC = .92). However, it was noted smallest detectable differences were a high percentage of mean values for all measures. Conclusions: The most reliable JPS measurement for asymptomatic participants has been identified. Practitioners should use this protocol when collecting JPS data during prescreening sessions. However, generalizability of findings to a class/group of clients exhibiting knee pathologies should be done with caution.

Background: Patellofemoral pain syndrome (PFPS) is one of the most common knee injuries in athletes and non-athletes. Due to the pain and muscle inhibition, it is possible that the disorder has negative effects on joint position sense. Cryotherapy is one of the most common methods applied in sports injuries. Objectives: The aim of this study was to evaluate the effect of topical cooling with ice and cold spray on knee joint position sense of athletes with PFPS. Methods: In this quasi-experimental study, 30 athletes with PFSP were divided into two groups of cold spray and crushed ice application. The effect of cooling on joint position sense was measured by the target reconstruction method (30° of knee flexion) while standing. In order to analyze the data, SPSS 23 and statistical tests of Shapiro-Wilk, paired t-test, and independent t-tests were used. The absolute error of 30° knee flexion angle reconstruction immediately after cryotherapy was significantly higher than before it in various cooling methods. Nevertheless, crushed ice application had a greater impact on the accuracy of joint position sense than spraying. Results: The results of this study indicate the negative effects of cryotherapy on the accuracy of the knee joint position sense (P < 0.05). However, cryotherapy with crushed ice application has a greater effect on reducing the accuracy of joint position sense (P < 0.001) than cold spray (P < 0.001). Conclusions: Decreased accuracy of position sense is likely to cause mechanical instability and increase the rate of injury. Therefore, it is recommended to use crushed ice application rather than topical cooling to reduce the knee joint position sense.

Anterior Cruciate

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.

The purpose of this study was to determine if a difference exists in the reproducibility of knee joint flexion angles in an open versus a closed kinetic chain. Thirty generally healthy subjects (12 males, 18 females; mean age 23.8 years) participated. Subjects actively reproduced small, medium, and large knee flexion angles (with target angles of 15°, 45°, and 75°, respectively) in an open and a closed kinetic chain while being videotaped. Goniometric measurements were taken from the videotape of initial and reproduced joint angles. Data were analyzed using ANOVA with repeated measures on kinetic chain test position and joint angle. Subjects more accurately reproduced knee flexion angles in a closed kinetic chain position. The main effect for angle and the interaction of angle and test position were nonsignificant. The results indicate that knee joint position is more accurately reproduced in closed kinetic chain. Closed kinetic chain testing is also a more functional assessment of joint position sense, and thus closed kinetic chain assessment of lower extremity joint position sense is recommended.

Purpose: Anterior Cruciate Ligament (ACL) injury is the most common knee ligament injury during exercise, with a frequency of 36.9 per 100000 individuals. The characteristics of this injury are proprioception dysfunction. The present study aimed to investigate the knee proprioception after the reconstruction of ACL in soccer players. Methods: The study sample of this study was 20 elite male soccer players with an ACL injury experiencing post-reconstruction. The knee joint position sense of the study subjects was measured by Isokinetic (Gymnex model) at 30°, 45°, and 60° between the operated and non-operated knee. An Independent Samples t-test was used to compare the mean scores of the measured variables at the significance level of P≤0.05. Results: The obtained results suggested that the mean value of the angle reproduction test at 30° on the operated knee was significantly more than that of the non-operated knee (P=0.003). Moreover, the mean value of a passive angle reproduction test was significantly more than that of the active angle test in the operated knee (P=0.001). There was no significant difference between the mean value of 45° angle repair results in the non-operated and operated knee (P=0.99). The difference between active and passive tests in the operated knee on 45° was significant; the study subjects demonstrated higher mean scores in the active test (P=0.02). Additionally, the half-value in angle reproduction in 60° in the operated knee was significantly less than that of the non-operated knee (P=0.01). Eventually, there was no significant difference between the results of the test at this angle in the passive and active angle reproduction in the affected knee (P=0.22). Conclusion: The obtained data revealed that the knee joint position sense of the operated knee joint, compared to the non-operated knee in elite soccer players, along with the reconstruction of the ACL, was weaker than those of the non-operated knee.

AbstractThe proprioceptive information received from mechanoreceptors is potentially responsible for controlling the joint position and force differentiation. However, it is unknown whether cryotherapy influences this complex mechanism. Previously reported results are not universally conclusive and sometimes even contradictory. The main objective of this study was to investigate the impact of local cryotherapy on knee joint position sense (JPS) and force production sense (FPS). The study group consisted of 55 healthy participants (age: 21 ± 2 years, body height: 171.2 ± 9 cm, body mass: 63.3 ± 12 kg, BMI: 21.5 ± 2.6). Local cooling was achieved with the use of gel-packs cooled to -2 ± 2.5°C and applied simultaneously over the knee joint and the quadriceps femoris muscle for 20 minutes. JPS and FPS were evaluated using the Biodex System 4 Pro apparatus. Repeated measures analysis of variance (ANOVA) did not show any statistically significant changes of the JPS and FPS under application of cryotherapy for all analyzed variables: the JPS’s absolute error (p = 0.976), its relative error (p = 0.295), and its variable error (p = 0.489); the FPS’s absolute error (p = 0.688), its relative error (p = 0.193), and its variable error (p = 0.123). The results indicate that local cooling does not affect proprioceptive acuity of the healthy knee joint. They also suggest that local limited cooling before physical activity at low velocity did not present health or injury risk in this particular study group.

Objectives: The aim of this study was to assess the relationship between functional knee joint position sense (JPS) and functional performance following ACL reconstruction Methods: Seven male patients (mean age=32,66 ±6,47) who had undergone ACL reconstruction and 10 male healthy control subjects participated in the study. Knee joint position sense was evaluated by reproduction of 20° knee flexion angle in weight-bearing position with single and bilateral limb movement into flexion and extension. The deviations in the angle were recorded and compared to both noninjured side and healthy controls’. Functional performance was evaluated with Single Leg Hop Test in both injured and non-injured sides. The scores were also compared with healthy controls and non-injured sides. Relationship between measured values was tested with Spearman Correlation Analysis. Results: There was no significant difference in knee joint position sense in functional position between the operated and uninjured knees of patients or between patients and healthy controls (p>0,05). However, there is significant difference in Single Leg Hop test scores between operated and non-operated or between patients and healthy controls (p=0,037; p<0,05). There was no significant correlation between Single Leg Hop test scores and knee joint position sense (p>0,05). Conclusion: There was no evidence of impaired joint position sense in weight-bearing positions in subjects with ACL reconstruction but there was a decrease in functional performance. This decrease in functional performance may depend on the other parameters except proprioceptive deficits.
