Variables associated with active spondylolysis Gregg et al. <20yo males more likely to develop spondylolysis than females or >20’s. Most likely due to participation in rotation and jumping sports.

The authors suggest that time to stabilise (TTI) is not sensitive enough to pick up improvements 2. Alternatively, bracing prevents gross movement but doesn’t help with the mid range proprioception required for stability. Shoulder functional ratio in elite junior tennis players Saccol et al. 1. Concentrically external rotators should be at least 2/3rds of the strength of the internal rotators (Ellenbecker & Davies 2000) 2. Eccentric strength of external...
