Topic Overview

Activities that may increase the risk of carpal tunnel syndrome include:

• Repetitive motions.
  • Continuous use of the hands and fingers, as when knitting or doing needlepoint with the wrist bent (flexed)
  • Frequent bending or twisting of the wrist, as when using a screwdriver
  • Repeated squeezing or gripping with the hand, as when using a spray bottle
  • Moving the fingers while the wrist is bent inward or flexed, as when playing musical instruments or typing
• Use of vibrating tools such as sanders.
• Use of a cane, wheelchair, or crutches, or doing certain sports (such as long-distance cycling) that require continuous forceful grasping with the wrist in an awkward position.
• Bending the wrist during sleep.
