The effect of experimentally-induced gluteal muscle paralysis on joint kinematics, reaction forces and dynamic balance performance during lunges Open
Despite altered mechanics and reduced joint loading following selective gluteal paralysis, participants were able to complete the lunge task, even if the lunge position was higher, and compensatory pelvic flexion and rotation towards the a…

Update of a prediction model for postoperative shoulder stiffness after arthroscopic rotator cuff repair Open
Background Arthroscopic rotator cuff repair (ARCR) is a common procedure, and postoperative shoulder stiffness (POSS) is one of its most frequent adverse events, potentially necessitating individualized therapy. Our objectives were to upda…

The effect of experimentally induced gluteal muscle weakness on joint kinematics, reaction forces, and dynamic balance performance during stair climbing Open
A weakness in the hip abductors severely affected stair climbing performance. Those who managed to complete the task demonstrated abnormal kinematics, reduced joint reaction forces, and poorer dynamic balance.

Acromial Morphology and Its Relation to the Glenoid Is Associated with Different Partial Rotator Cuff Tear Patterns Open
The pathogenesis of subacromial impingement syndrome is controversially discussed. Assuming that bursal sided partial tears of the supraspinatus tendons are rather the result of a direct subacromial impact, the question arises whether ther…
