Mechanical influence of finger taping in sport climbing

The effect of taping on distal (DIP) and proximal (PIP) interphalangeal joint angles was measured with electrogoniometers in II subjects before and after taping. Taping of the proximal phalanx and the A2 pulley reduces the DIP hyperextension by 10°, and the PIP flexion by 14° . The latter results into an average decrease of 11% of the force at the distal A2-pulley fiber. Thus, taping has an indirect protective effect on the A2-pulley, and on the DIP joint
