Mikael Pernfors “TECHNOVIBR” Cosch Racket String Vibration Absorber VINTAGE RARE

Description

Mikael Pernfors “TECHNOVIBR” Cosch Racket String Vibration Absorber VINTAGE Tennis Elbow
Equipped with a new and unique membrane/runner system, eliminates in a split second parisitic high frequency vibrations without modifying low frequency vibrations, essential for optimal efficiency of the frame.
High frequency vibrations produce peaks of residence, which interfere with proprioception separation of the hand. This creates a reflex tightening of the grip by contraction and relaxing of EPICONDYL ER and EPITROCHLIAN muscles, which cause micro traumatism to tendinous insertions, often a source of tennis elbow 🎾
This device helps to prevent tennis elbow with rapid elimination of vibrations that impact a better touch and decrease risk of relapse or reoccurrence.
US patent 4 761.007
