Stress Drives Soccer Athletes' Wellness and Movement: Using Convergent Cross-Mapping to Identify Causal Relationships in a Dynamic Environment.

Purpose: Prediction of athlete wellness is difficult-or, many sports-medicine practitioners and scientists would argue, impossible. Instead, one settles for correlational relationships of variables gathered at fixed moments in time. The issue may be an inherent mismatch between usual methods of data collection and analysis and the complex nature of the variables governing athlete wellness.

How Advancement in Bone Science Should Inform the Examination and Treatment of Femoral Shaft Bone Stress Injuries in Running Athletes.

Stress fractures likely have a 1-2% incidence in athletes in general. In runners, a more vulnerable population, incidence rates likely range between 3.2 and 21% with female runners having greater susceptibility.

Individualized Exercise Prescription for Athletes Using a Construct-Based Model.

Rehabilitation professionals prescribe exercise regularly with the goals of decreasing pain, increasing function, and returning athletes to competition. To maximize the effect of an exercise intervention, the program must be individualized and in context for the athlete considering biopsychosocial aspects of care. Current models of exercise prescription may not be ideal considering that less than 50% of injured athletes return to their pre-injury level.

State dependence: Does a prior injury predict a future injury?

The sports medicine literature is filled with associations between injury and causal factors. However, those results have been inconsistent. We're left wondering which of our athletes might need more attention and where our efforts might be best spent.

Variation in reported safety of lumbar interbody fusion: influence of industrial sponsorship and other study characteristics.

Study Design: Systematic review.

Objective: To quantify variability in undesirable outcomes among studies of lumbar interbody fusion using stand-alone cage devices, and to determine whether author conflicts of interest contribute to variability.

Summary Of Background Data: Promising early studies of lumbar fusion with stand-alone cage devices led to rapid uptake of the technique, but some surgeons later expressed reservations regarding efficacy and safety.
