Sleep, Dance Exposure Hours, and Injury Risk in Collegiate Dancers.

Introduction: Sleep is essential for athletes and dancers to optimize recovery. Poor sleep negatively affects cognitive function and injury risk in athletes. Increased athletic participation (hours) is associated with decreased total sleep and quality in athletes.

Tendinopathies of the Foot and Ankle.

Tendinopathies of the foot and ankle, including posterior tibial, peroneal, and tibialis anterior, are commonly overlooked by primary care physicians. The posterior tibial tendon is the main dynamic stabilizing muscle of the medial longitudinal arch. Patients who have posterior tibial tendinopathy present with medial ankle pain, pes planovalgus deformity, and a positive too many toes sign.

Inter-rater and intra-rater reliability of a clinical protocol for measuring turnout in collegiate dancers.

Reliable methods of measuring turnout in dancers and comparing active turnout (used in class) with functional (uncompensated) turnout are needed. Authors have suggested measurement techniques but there is no clinically useful, easily reproducible technique with established inter-rater and intra-rater reliability. We adapted a technique based on previous research, which is easily reproducible.

Nonoperative Treatment of Patellar Instability.

The treatment of patellar instability is challenging and typically begins with nonoperative methods. Clinical decisions are made on an individual basis and may vary according to a number of factors. First-time patellar dislocations most commonly occur during sports participation.
