The case of a Division I female college basketball player with a complete Achilles tendon rupture, who successfully progressed through an open surgical repair of Achilles tendon, is presented. The case provides evidence that early mobilization and weight bearing can be used while still protecting the repaired tendon.

Recovery for knee-extensor-muscle voluntary strength is slower to recover than evoked tetanic-contractile characteristics following partial meniscectomy. The traditional rehabilitation protocol appears to be insufficient for this purpose.

The authors describe research leading to developing interval throwing programs for baseball players other than pitchers. They describe programs designed for cathers and infielders of all age groups, one for 13-year-old outfielders, and one for all other levels.

Measuring passive knee extension before and after administering general anesthesia contributes to undertanding the mechanism of how flexibility is limited. Results in this study may have been produced by diminished neural drive to antagnist muscle groups, suggesting a more complex neural means for flexibility than the traditional model of neural drive to an agonist muscle.

Force-couple coactivation of the shoulder joint does not appear to be significantly changed following muscle fatigue. This conclusion was reached after research with exercises including segmental stabilization, horizontal abduction, push-up, and rotational movement on a slide board.

The author appreciates comments noting imperfections in statistical analysis of earlier data, yet notes the inability to reject the major null hypothesis of the earlier study was not due to using gender as a factor or inadequate sample size. Effect size appearing to be low resulted from the difference between group means being low.

The author examines the statistical analysis used by researchers in their study of arm elevation and finds it failing to address the balance between types 1 and 2 errors. He is also concerned with a lack of accounting for potential differences between genders in their study, though he commends the study overall.
