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.

Context: Knee joint-position sense (JPS) is a key parameter for optimum performance in many sports but is frequently negatively affected by injuries and/or fatigue during training sessions. Although evaluation of JPS may provide key information to reduce the risk of injury, it often requires expensive and/or complex tools that make monitoring proprioceptive deterioration difficult. Objective: To analyze the validity and reliability of a digital inclinometer to measure knee JPS in a closed kinetic chain (CKC). Design: The validity and intertester and intratester reliability of a digital inclinometer for measuring knee JPS were assessed. Setting: Biomechanics laboratory. Participants: 10 athletes (5 men and 5 women; 26.2 ± 1.3 y, 71.7 ± 12.4 kg; 1.75 ± 0.09 m; 23.5 ± 3.9 kg/m2). Intervention: Knee JPS was measured in a CKC. Main Outcome Measures: Absolute angular error (AAE) of knee JPS in a CKC. Results: Intraclass correlation coefficient (ICC) and standard error of the mean (SEM) were calculated to determine the validity and reliability of the inclinometer. Data showed that the inclinometer had a high level of validity compared with an isokinetic dynamometer (ICC = 1.0, SEM = 1.39, P < .001), and there was very good intra- and intertester reliability for reading the inclinometer (ICC = 1.0, SEM = 0.85, P < .001). Compared with AutoCAD video analysis, inclinometer validity was very high (ICC = 0.980, SEM = 3.46, P < .001) for measuring AAE during knee JPS in a CKC. In addition, the intertester reliability of the inclinometer for obtaining AAE was very high (ICC = .994, SEM = 1.67, P < .001). Conclusion: The inclinometer provides a valid and reliable method for assessing knee JPS in a CKC. Health and sports professionals could take advantage of this tool to monitor proprioceptive deterioration in athletes.

Background Shoulder pain or injury is the most common issue facing elite competitive swimmers and the most frequent reason for missed or modified training. Literature suggests that highly repetitive upper limb loading leads to inappropriate adaptations within the shoulder complex. The most likely maladaptations to occur are variations in shoulder rotational range of motion, reduction in joint position sense and shortened pectoralis minor length. This has yet to have been confirmed in experimental studies. The aim of this study was to investigate the short-term effects of swimming training load upon internal and external rotation range of motion, joint position sense and pectoralis minor length. Method Sixteen elite swimmers training in the British Swimming World Class programme participated. Measures of internal and external range of motion, joint position sense error score and pectoralis minor length were taken before and after a typical 2 h swimming session. Results Following swimming training shoulder external rotation range of motion and pectoralis minor length reduced significantly (−3.4°, p = <0.001 and −0.7 cm, p = <0.001, respectively), joint position sense error increased significantly (+2.0° error angle, p = <0.001). Internal rotation range of motion demonstrated no significant change (−0.6, p = 0.53). Discussion This study determined that elite level swimming training results in short-term maladaptive changes in shoulder performance that could potentially predispose them to injury.
