Is Throckmorton’s Sign predictive?

The Olympics are here and it’s time for some sports medicine hypothesis generation.

Yet, one cannot help but wonder if it might predict which side will be injured even before a traumatic episode takes place.

Cycling is the obvious sport for testing this hypothesis, for a number of reasons…

  4. A perfect choice to test your hypothesis against.
