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: 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.

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.

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.

Research  background  and  hypothesis.  Proprioception  is  important  in  the  prevention  of  injuries  as  reduced proprioception  is  one  of  the  factors  contributing  to  injury  in  the  knee  joint,  particularly  the  ACL.  Therefore, proprioception appears not only important for the prevention of ACL injuries, but also for regaining full function after ACL reconstruction.Research aim. The aim of this study was to understand how proprioception is recovered four and five months after anterior cruciate ligament (ACL) reconstruction.Research methods. The study included 15 male subjects (age – 33.7 ± 2.49 years) who had undergone unilateral ACL reconstruction with a semitendinosus/gracilis (STG) graft in Kaunas Clinical Hospital. For proprioceptive assessment, joint position sense (JPS) was measured on both legs using an isokinetic dynamometer (Biodex), at knee flexion of 60° and 70°, and at different knee angular velocities of 2°/s and 10°/s. The patients were assessed preoperatively and after 4 and 5 months, postoperatively.Research results. Our study has shown that the JPS’s (joint position sense) error scores  to a controlled active movement is significantly higher in injured ACL-deficient knee than in the contralateral knee (normal knee) before surgery and after four and five months of rehabilitation.  After 4 and 5 months of rehabilitation we found significantly lower values in injured knees compared to the preoperative data. Our study has shown that in injured knee active angle reproduction errors after 4 and 5 months of rehabilitation were higher compared with the ones of the uninjured knee. Proprioceptive ability on the both legs was  independent of all differences angles for target and starting position for movement. The knee joint position sense on both legs depends upon the rate of two different angular velocities and the mean active angle reproduction errors at the test of angular velocity slow speed was the highest compared with the fast angular velocity. Discussion and conclusions. In conclusion, our study shows that there was improvement in mean JPS 4 and 5 months after ACL reconstruction, but it did not return to normal indices.Keywords: knee joint, joint position sense, angular velocity, starting position for movement.

BACKGROUND: Performing thoracic manipulations for neck pain can result in immediate improvements in neck function. OBJECTIVE: The aim of this study was to investigate the immediate effects of thoracic manipulation on cervical joint position sense and cervical range of motion in individuals with chronic mechanical neck pain. METHODS: Eighty male volunteers between 18–25 years and having chronic or recurrent neck or shoulder pain of at least 3 months duration with or without arm pain were randomized into two groups: Thoracic Manipulation Group (TMG:50) and Control Group (CG:30), with a pretest-posttest experimental design. The TMG was treated with thoracic extension manipulation while the CG received no intervention. Cervical joint position error and cervical range of motion of the individuals were assessed at baseline and 5 minutes later. RESULTS: There was no difference in demographic variables such as age (p= 0.764), Body Mass Index (p= 0.917) and Neck Pain Disability Scale (NPDS) scores (p= 0.436) at baseline outcomes between TMG and CGs. Joint position error outcomes between the two groups following intervention were similar in all directions at 30 and 50 degrees. Differences in range of motion following intervention in neck flexion (p< 0.001) and right rotation (p= 0.004) were higher in TMG compared to CG. CONCLUSIONS: A single session of thoracic manipulation seems to be inefficient on joint position sense in individuals with mild mechanical neck pain. However, thoracic manipulation might be an effective option to increase flexion and rotation of the cervical region as an adjunctive to treatment.
