Reliability and validity of new isokinetic strength assessment for rotator cuff muscles in a muscle architecture-based position.

Background/aim: Isokinetic strength assessment of the rotator cuff muscle is frequently applied in a variety of shoulder postures, but none of these consider muscular architecture, which is one of the most important aspects of improving strength development. This study aimed to examine the test and retest reliability and validity of the muscle architecture-based position (MABP), which is 25° abduction and 20° external rotation, in healthy subjects to be able to select a better isokinetic assessment position for shoulder rotator cuff muscles.

Materials And Methods: A total of 54 healthy males with a mean age of 21.

Treatment of a medial collateral ligament sprain using prolotherapy: a case study.

Prolotherapy is effective in treating refractory tendinopathies, but inadequate clinical evidence exists to recommend its use as a treatment for acute or chronic, medial collateral ligament (MCL) injuries. The current case study documents an illustrative case of a rugby player who had a grade 2 sprain of the MCL and shows the clinical and radiological outcomes following injections of 15% dextrose combined with 0.2% lidocaine.
