Research has shown that the tuning fork tensioner, made of plastic with a black granite appearance, is a sturdy, reliable instrument.
The tensioner is ideal for diagnosing polyneuropathy.

The tuning fork tensioner eliminates the difficulty of striking the tuning fork. With the tensioner, striking the fork will always be done in an identical manner, making the initial vibration strength constant.
The tuning fork causes a lot of finger irritation, which becomes less stressful with the tensioner.
