Development and validation of a sport-specific shoulder score questionnaire for functional fitness and weightlifting athletes.

Background: So-called scores are a frequently used evaluation system in clinical examinations to assess the function or limitations of a joint such as the shoulder. However, research indicates that these general scores often have limited validity for specific patient groups, such as athletes. Known as a demanding patient population, athletes have unique needs.

The Impact of the SARS-COVID-19 Lockdowns on the Subjectively Perceived Performance Level of Amateur Athletes after Returning to the Gyms.

Since December 2019, few issues have garnered as much global attention as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-19). The imposed lockdowns in 2020/21, which led to the closure of all gyms, barred people from participating in their favourite sports activities. This study explores athletes' self-evaluations of their performance levels upon return to training facilities post-reopening.

Shoulder pathologies in CrossFit: a magnetic resonance imaging study of 51 cases.

Background: Recent scientific work shows that the most common injuries in CrossFit© occur in the shoulder joint. This paper aims to provide a review of shoulder pathologies in a young CrossFit cohort via MRI and clinical examination.

Methods: A survey was conducted in 13 CrossFit "boxes" in Germany, in which athletes with recurrent shoulder pain could report for a clinical examination and MRI diagnostic.

Comparison of sEMG Onset Detection Methods for Occupational Exoskeletons on Extensive Close-to-Application Data.

The design of human-machine interfaces of occupational exoskeletons is essential for their successful application, but at the same time demanding. In terms of information gain, biosensoric methods such as surface electromyography (sEMG) can help to achieve intuitive control of the device, for example by reduction of the inherent time latencies of a conventional, non-biosensoric, control scheme. To assess the reliability of sEMG onset detection under close to real-life circumstances, shoulder sEMG of 55 healthy test subjects was recorded during seated free arm lifting movements based on assembly tasks.
