Improved reporting of overuse injuries and health problems in sport: an update of the Oslo Sport Trauma Research Center questionnaires.

In 2013, the Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC-O) was developed to record the magnitude, symptoms and consequences of overuse injuries in sport. Shortly afterwards, a modified version of the OSTRC-O was developed to capture all types of injuries and illnesses-The Oslo Sports Trauma Research Center Questionnaire on Health Problems (OSTRC-H). Since then, users from a range of research and clinical environments have identified areas in which these questionnaires may be improved.

Attitudes, beliefs, and behavior toward shoulder injury prevention in elite handball: Fertile ground for implementation.

We aimed to examine attitudes, beliefs, and current behavior toward risk factors and prevention of shoulder injuries, and to investigate the application of an exercise program during a cluster-randomized controlled trial aiming to prevent shoulder injuries in elite handball. All captains and coaches of 44 elite handball teams (22 male and 22 female) constituting the intervention (21 teams) and control arm (n = 23 teams) in the trial were invited to take part in a survey. A questionnaire, based on the Reach, Efficacy, Adoption, Implementation, and Maintenance framework, addressing the end user perspective on risk factors and prevention of shoulder injuries, as well as key issues related to the application of the Oslo Sports Trauma Research Center (OSTRC) Shoulder Injury Prevention Programme, was distributed using electronic survey software.

Prevalence and burden of overuse injuries in elite junior handball.

Aim: To record overuse injuries among male junior handball players throughout a handball season.

Design: Prospective cohort study.

Methods: Ten Norwegian junior male handball teams (145 players aged 16-18 years) were followed for one 10-month season.

Excitation and desorption of physisorbed H via theΣu2 electron scattering resonance.

Our high-resolution electron energy-loss measurements concern physisorbed H and comprise differential cross sections for the excitation of the internal H modes and the H-surface bonding mode and their combinations and extend over the electron impact energy range of the classical low-energy H Σu2 resonance. Comparison with corresponding data for the excitation of the internal modes of gas phase H reveals that strong elastic electron reflectivity from the Cu(100) substrate profoundly distorts the inelastic scattering pattern for physisorbed H. We find that this influence can be corrected for and that the resulting peak cross sections agree with the H gas phase data, in accordance with theoretical predictions for the excitation of the internal H vibration.

Risk factors for overuse shoulder injuries in a mixed-sex cohort of 329 elite handball players: previous findings could not be confirmed.

Background: Shoulder injuries are common among handball players and predominantly characterised by overuse characteristics. Reduced total glenohumeral rotation, external rotation weakness and scapular dyskinesis have been identified as risk factors among elite male handball players.

Aim: To assess whether previously identified risk factors are associated with overuse shoulder injuries in a large cohort of elite male and female handball players.

Preventing overuse shoulder injuries among throwing athletes: a cluster-randomised controlled trial in 660 elite handball players.

Background: Shoulder problems are highly prevalent among elite handball players. Reduced glenohumeral rotation, external rotation weakness and scapula dyskinesis have been identified as risk factors.

Aim: Evaluate the effect of an exercise programme designed to reduce the prevalence of shoulder problems in elite handball.

Reduced glenohumeral rotation, external rotation weakness and scapular dyskinesis are risk factors for shoulder injuries among elite male handball players: a prospective cohort study.

Aim: To determine whether rotator cuff strength, glenohumeral joint range of motion and scapular control are associated with shoulder injuries among elite male handball players.

Methods: A total of 206 players in the Norwegian elite handball league for men were tested prior to the 2011-2012 season. Measures included: (1) glenohumeral internal and external rotation range of motion, (2) isometric internal rotation, external rotation and abduction strength and (3) assessment of scapular dyskinesis.

Benchmarking van der Waals density functionals with experimental data: potential-energy curves for H2 molecules on Cu(111), (100) and (110) surfaces.

Detailed physisorption data from experiment for the H(2) molecule on low-index Cu surfaces challenge theory. Recently, density functional theory (DFT) has been developed to account for nonlocal correlation effects, including van der Waals (dispersion) forces. We show that the functional vdW-DF2 gives a potential-energy curve, potential-well energy levels and difference in lateral corrugation promisingly close to the results obtained by resonant elastic backscattering-diffraction experiments.

Development and validation of the Affective Self Rating Scale for manic, depressive, and mixed affective states.

Most rating scales for affective disorders measure either depressive or hypomanic/manic symptoms and there are few scales for hypomania/mania in a self-rating format. We wanted to develop and validate a self-rating scale for comprehensive assessment of depressive, manic/hypomanic and mixed affective states. We developed an 18-item self-rating scale starting with the DSM-IV criteria for depression and mania, with subscales for depression and mania.

General practitioners' conceptions of depressive disorders in relation to regional sales levels of antidepressive drugs. A study based on a postal survey and ecological data.

Objectives: To examine how local sales levels of antidepressive agents (ADs) correlated with GPs' conceptions of depressive disorders and of factors that may influence their work with depressed patients.

Design: A postal questionnaire survey to GPs requesting their conceptions of depression and their opinions of additional factors that may influence their work with depressed patients. GPs' conceptions and opinions were compared with local sales rates of ADs.

General practitioners' conceptions about treatment of depression and factors that may influence their practice in this area. A postal survey.

Background: The way GPs work does not appear to be adapted to the needs of depressive patients. Therefore we wanted to examine Swedish GPs' conceptions of depressive disorders and their treatment and GPs' ideas of factors that may influence their manner of work with depressive patients.

Methods: A postal questionnaire to a stratified sample of 617 Swedish GPs.
