One of the most plausible causes for tennis elbow for a one hand backhand is described by biomechanical researcher D. Knudson in his very interesting & informative book, Biomechanical Principles of Tennis Technique (2006). He discusses why the wrist should be extended and not flexed for the 1hbh. He says that the pro's use extended wrists and many average players use flexed wrists. When I look at videos I see the pros using extended wrists on the 1hbh. In addition, the flexed wrist stretches the elbow muscles that are injured in TE making stress from wrist flexion seem plausible as a cause of TE injury.

See if you can find any videos of pros impacting the ball with flexed wrists on the 1hbh. ? % ?
