These limitations would tend to inflate estimates of the accuracy of MRI. In summary, the results of this study indicate that provocative wrist tests are of limited value for diagnosing wrist ligament injuries. The SS test and MC test are mildly useful in the diagnosis of SL and arcuate ligament injuries. MRI slightly improves the diagnosis of TFCC Cell Cycle inhibitor injury and lunate cartilage damage compared to provocative tests alone. Ethics: The University of Sydney Ethics Committee approved this study. All participants gave written informed

consent before data collection began. “
“Summary of: Davis CL et al (2011) Exercise improves executive function and achievement and alters brain activation in overweight children: a randomized controlled trial.

Health Pscyh 30: 91–98. [Prepared by Nora Shields, CAP Editor.] Question: Does aerobic exercise improve cognition and academic http://www.selleckchem.com/products/abt-199.html achievement in overweight children aged 7–11 years? Design: Randomised, controlled trial with concealed allocation and blinded outcome assessment. Setting: After school program in the United States. Participants: Overweight, inactive children aged 7–11 years with no medical contraindication to exercise. Randomisation of 171 participants allocated 56 to a high dose exercise group, 55 to a low dose exercise group, and 60 to a control group. Interventions: Both exercise groups were transported to an after school exercise program each school day and participated in aerobic activities including running games, jump rope, and modified basketball and soccer. The emphasis was on intensity, enjoyment, and safety, not competition or skill enhancement. The student-instructor ratio

was 9:1. Heart rate monitors were used to observe the exercise intensity. Points were awarded for maintaining an average of > 150 beats per minute and could be redeemed for weekly prizes. The high dose exercise group received 40 min/day aerobic exercise and the low dose exercise group received 20 min/day aerobic exercise and 20 min/day unsupervised sedentary activities Endonuclease including board games, drawing, and card games. The average duration of the program was 13 ± 1.6 weeks. The control group did not receive any after school program or transportation. Outcome measures: The primary outcome was the Cognitive Assessment System taken at baseline and postintervention. This measure tests four cognitive processes: planning (or executive function), attention, simultaneous, and successive tasks with each process yielding a standard score with a mean of 100 and a SD of 15. Secondary outcome measures were the broad reading and mathematics clusters of the Woodcock-Johnson Tests of Achievement III. Results: 164 participants completed the study. At the end of the intervention period, there was a dose-response benefit of exercise on executive function (linear trend p = 0.
