Effects of stretching the gastrocnemius muscle.

Many authors currently disagree on the amount of time necessary to provide an adequate stretch flexibility. Since gastrocnemius equinus has been recognized as a cause of athletic injury, the authors performed a study to test what may be an adequate amount of stretching a gastrocnemius to improve flexibility. This study could not be conducted blind, and it was hoped that the contralateral leg could offer some control. The results of this study are presented here and should be kept in mind when evaluating and treating patients with ankle equinus, especially when considering surgical intervention.
