Objectives: To determine test re-test reliability and construct validity of the star-track test of manual dexterity. Design: Test re-test reliability was tested in a controlled study. Construct validity was tested in a blinded randomized crossover study. Setting: The study was performed at a university hospital in Denmark.Participants: A total of 11 subjects for test re-test and 20 subjects for the construct validity study were included. All were healthy volunteers. Intervention: The test re-test trial had two measurements with 2 days pause in between. The interventions in the construct validity study included baseline measurement, intervention 1: fatigue, intervention 2: stress, and intervention 3: fatigue and stress. There was a 2 day pause between each intervention. Main outcome measure: Integrated measure of completion time and number of errors. Results: All participants completed the study (test re-test n = 11; construct validity n=20). Test re-test showed a strong Pearson product-moment correlation (r= 0.90, n= 11, P < 0.01) with no sign of learning effect. The 20 subjects in the construct validity trial were randomized to the order of the four interventions, so that all subjects completed each intervention once. A repeated measures ANOVA determined that mean integrated measure differed between interventions (p = 0.003). Post hoc tests using Bonferroni correction revealed that compared with baseline all interventions had significantly higher integrated scores ranging from 47-59% difference in mean. Conclusion: The star track test of manual dexterity had a strong test re-test reliability, and was able to discriminate between a subject´s normal manual dexterity and dexterity after exposure to fatigue and/or stress.

Objective: To assess the effect of scapular taping on the functional throwing performance index and medicine ball throwing performance. Design: A Randomized crossover trial. Setting: Out-patient Physiotherapy department at a university hospital. Participants: Forty-four healthy participants were randomly assigned to scapular and sham taping procedure. Outcome measure: Functional throwing performance index (FTPI) and Medicine ball throw (MBT) were recorded at baseline and following each taping procedure. Results: Analysis of variance with repeated measures on the dependent variable (Index percentage for FTPI and distance in meters for MBT) were used for analysis. Significant improvements were observed following scapular taping ([Formula: see text]) on FTPI and MBT. Post hoc analysis for FTPI and MBT obtained a statistically significant difference between the scapular taping condition to baseline ([Formula: see text]) with a mean difference of [Formula: see text]%; [Formula: see text][Formula: see text]m, respectively. Similarly, scapular taping to sham taping ([Formula: see text]) shown a significant difference of [Formula: see text]% on FTPI and [Formula: see text][Formula: see text]m in MBT. No significant differences were found following sham taping on FTPI and MBT. Conclusion: Scapular taping improves functional throwing performance index and medicine ball throwing performance among normative young adults.

Abstract. In five studies, we evaluated the psychometric properties of a revised German version of the State Self-Esteem Scale (SSES; Heatherton & Polivy, 1991 ). In Study 1, the results of a confirmatory factor analysis on the original scale revealed poor model fit and poor construct validity in a student sample that resembled those in the literature; thus, a revised 15-item version was developed (i.e., the SSES-R) and thoroughly validated. Study 2 showed a valid three-factor structure (Performance, Social, and Appearance) and good internal consistency of the SSES-R. Correlations between subscales of trait and state SE empirically supported the scale’s construct validity. Temporal stability and intrapersonal sensitivity of the scale to naturally occurring events were investigated in Study 3. Intrapersonal sensitivity of the scale to experimentally induced changes in state SE was uncovered in Study 4 via social feedback (acceptance vs. rejection) and performance feedback (positive vs. negative). In Study 5, the scale’s interpersonal sensitivity was confirmed by comparing depressed and healthy individuals. Finally, the usefulness of the SSES-R was demonstrated by assessing SE instability as calculated from repeated measures of state SE.
