“…Results from the heteroscedasticity analysis and Bland-Altman plots indicate that the worse the performance in the back scratch, 8 feet up and go and chair sit and reach tests, the worse the degree of the agreement.

“…In the first study [1], which focused on the lower extremities, all peak torque measures had an ICC > 0.90 with the exception of eccentric flexion (0.83), and all work measures had an ICC > 0.85. In the second study [2], which focused on the upper extremities, they found that peak torque showed high reliability for the abduction (ICC = 0.88) and adduction (ICC = 0.89) phases in the concentric/eccentric test. However, in the concentric/concentric test, peak torque showed low reliability in the abduction phase (ICC = 0.29) and good reliability in the adduction phase (ICC = 0.92).…”

The aim of the present study was to determine the reliability and feasibility of physical fitness tests in female fibromyalgia patients. 100 female fibromyalgia patients (aged 50.6±8.6 years) performed the following tests twice (7 days interval test-retest): chair sit and reach, back scratch, handgrip strength, arm curl, chair stand, 8 feet up and go, and 6-min walk. Significant differences between test and retest were found in the arm curl (mean difference: 1.25±2.16 repetitions, Cohen d=0.251), chair stand (0.99±1.7 repetitions, Cohen d=0.254) and 8 feet up and go (-0.38±1.09 s, Cohen d=0.111) tests. Intraclass correlation coefficients (ICC) range from 0.92 in the arm curl test to 0.96 in the back scratch test. The feasibility of the tests (patients able to complete the test) ranged from 89% in the arm curl test to 100% in the handgrip strength test. Therefore, the reliability and feasibility of the physical fitness tests examined is acceptable for female fibromyalgia patients.

“…In healthy individuals, the use of isokinetic dynamometry to evaluate the knee strength when subjects receive adequate instructions and are familiar with the equipment is sufficiently reliable [10,11], but the reliability in PD patients still remains unknown, which impairs and limits the appropriate interpretation of results. In this regard, reliability is considered an important prerequisite for the correct interpretation of isokinetic dynamometry data, which allows the clinician to identify whether or not a genuine change has occurred [12]. Therefore, the aim of the current study was to determine the relative and absolute intra-session reliability of peak torque and work measurements for isokinetic concentric knee and elbow extension and flexion in PD patients.…”

Isokinetic Strength in Peritoneal Dialysis Patients: A Reliability Study

Although there are studies assessing the effects of interventions on the knee strength of patients undergoing dialysis, there are no previous studies investigating the test-retest reliability of isokinetic measures in people undergoing peritoneal dialysis. The objective of this study was to determine the relative and absolute reliability of peak torque and work measurements for isokinetic concentric knee and elbow extension and flexion in peritoneal dialysis patients. Thirty-one patients undergoing peritoneal dialysis (19 males) participated in the current study. All isokinetic tests were performed using a Biodex System 3. Participants performed three concentric repetitions of each test (flexion or extension) with the dominant limb (knee and elbow) at 60 • /s. Peak torque (Nm) and work (J) were extracted. The intraclass correlation coefficient (ICC), standard error of measurement (SEM), and smallest real difference (SRD) were calculated. The results showed that all knee peak torque and work measures had an ICC of >0.90. On the other hand, the ICC for peak torque and work in the elbow concentric extension was <0.90, while the remaining elbow-related variables achieved an excellent reliability. Therefore, isokinetic dynamometry is a reliable technique to evaluate peak torque and work for concentric flexion and extension in both the knee and elbow joints in patients undergoing peritoneal dialysis.

Effects of occlusal splints on shoulder strength and activation

Introduction: The use of oral appliances to enhance sports performance has been advocated by some authors, however, studies addressing the effectiveness of these strategies are inconclusive. Methods: Here we investigate the effects of dental occlusions on shoulder strength. Fourteen healthy male subjects (age ¼ 21.67 ± 0.86 years) without temporomandibular joint (TMJ) disorder participated in this study. Isokinetic strength was evaluated in shoulder abduction/adduction and arm external/internal rotation tests. Three randomised conditions were assessed: (1) occlusal splint (OS), which repositioned the TMJ in centric relation; (2) placebo splint (PS); and (3) no-splint (N). The strength tests were performed at a speed of 60 /sec in concentric mode. Muscle activity was measured by surface electromyography (EMG) in the main muscles engaged in the movements. Results: Significant differences in peak torque between OS and both of the other experimental conditions were found in some of the analyzed variables. Moreover, there was significantly higher muscular EMG activation in the OS condition when compared to the other conditions for some of the tested muscles. These data suggest that splints may have a positive ergogenic effect on shoulder muscular strength in healthy male subjects. Conclusion: OS may provide an advantage for healthy subjects engaged in sports whereby shoulder and arm strength are important for performance. KEY MESSAGES Occlusal splints in centric relation position have an ergogenic effect, by increasing strength and muscle activation on shoulder in healthy subjects. These results could have implications for sports or other physical activities were arm and shoulder strength are important.
