- The systematic review aims to establish normative strength values for glenohumeral rotation in rugby players, utilizing 15 articles and data from 573 participants.
- Two main assessment methods for shoulder rotation strength are identified: isometric (with the arm at 0° or 90° abduction) and isokinetic methods, highlighting the lack of studies on neutral position isometric strength.
- Normative values found are 2.04 ± 0.15 N.kg for internal rotation and 2.11 ± 0.13 N.kg for external rotation based on isometric contractions at 90° abduction in male rugby union players, providing useful data for coaches and therapists in injury rehabilitation and return-to-play decisions.

- - MRI scans showed brain lesions consistent with past concussions, prompting testosterone replacement therapy which quickly improved his symptoms.
- - This case highlights a previously unrecognized complication of rugby-related injuries: chronic dysfunction of the anterior pituitary gland post-trauma.
