Female athelete triad syndrome in the high school athelete.
Thein-Nissenbaum & Carr
Triad = bone health-menstrual irregularities- poor nutrition
Poorer nutrition increases injury risk 2-3x in young females
Each component is associated with increased injury risk
Uninvolved versus target muscle contraction during contract-relax proprioceptive neuromuscular facilitation stretching
Azevedo et al.
Biceps contraction as effective as hamstring contraction in contract relax stretch of hamstring
Immediate effects of quantified hamstring stretching: Hold relax proprioceptive...
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. E.g. Cricket, gymnastics
Single leg hyperextension test was not valid (p=0.47).
The Influence of Mulligan ankle taping during balance performance in subjects with unilateral chronic ankle instability
Hopper et al.
Previously shown to be effective in preventing recurrent injuries.
? Works at end range to stop injury, but not inner range to improve proprioception.
Neck strength recovery following a single bout of specific strengthening exercise
Netto et al
Neck strength returned to previous level at 3 days post training.
Neck strength surpassed previous level at 5 days post training.
In females recovery may be delayed.
Correlation of three different knee joint position sense measures
Kiran et al.
Isokinetic dynamometer, electrogoniometer and two dimensional (2D) video analysis showed at least a fair correlation in both standing and sitting.
2D video analysis or electrogoniometer may be best for standing, however in sitting 2D video analysis may be...

Bracing does not improve dynamic stability in chronic ankle instability subjects
Gribble et al
1. 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...
