To answer your question, in my experience, no. However, keeping a loose, relaxed, grip through contact on every shot has CURED my TE. When your grip is loose, the shock of contact stops in your hand and doesn't transfer to your arm. A loose relaxed grip at contact also has the benefits of more power and more consistent clean ball striking. Conversely, tightening your grip at contact allows the shock of contact to transfer to your arm, reduces racquet head speed, and alters your swing path impairing clean ball striking.
