The Cinch Strap provides a means for regaining passive finger flexion using steady non-elastic force.
The Cinch Strap is applied for 1 hour gradually tightening the strap, 2-3 times a day.
The strap is applied in the clinic and a pen mark is made as a starting point. The patient then marks maximum gain with a pen at home.
The Cinch Strap can be applied in various ways, depending on the joint involved and the degree of extension contracture. The basic loop is used to maintain finger position.
Cinch Strap Applications
For PIP and DIP joint flexion the tip of the finger is in the loop and the loop encircles the finger.
The strap passes in back of the metacarpals and the loop encircles the finger on the distal end of the middle phalanx. This is the most common application.
