Low Back Stabilization Prediction Rule

Dr. GJohn Mullen Blog, Injuries, Latest&Greatest Leave a Comment

Clinical prediction rules (CPR) are meant to identify patients who would benefit from certain rehabilitation protocols. This study looked at the current CPR for identifying patients most likely to improve with lumbar stabilization exercise (LSE). The current CPR suggests four variables possess the greatest predictive power for treatment success: 1) Age <40 2) Straight leg raise (SLR) > 91 degrees …

Reliability of Shoulder Blade Timing Tests

Reliability of Shoulder Blade Timing Tests

Dr. GJohn Mullen Blog, Injuries, Latest&Greatest Leave a Comment

Alterations in neuromuscular control are thought to contribute to shoulder impingement. Specifically, this alteration in muscle timing is perpetuated by a muscular imbalance between the muscles which stabilize the shoulder and assist in overhead motion. Recently, rehabilitation focusing on improving the muscular imbalance demonstrates better results than purely strengthening. Unfortunately, the reliability of testing neuromuscular control is limited. The ability …

Manipulating work: rest intervals is a unique variable in time-based sports (swimming, cycling, running). Sports scientist Dr. Brent Rushall was among the first to suggest using high repetition, short rest, and short distance swimming training (ultra-short race pace training) to improve motor control. Many swim programs perform continuous swimming but with the power output the same, which group demonstrates changes …
