Prolonged keyboard use and prolonged manual pipetting are the most likely causes of repetitive motion injury at UC Davis. Excess stress without adequate recovery time can lead to repetitive motion injury. Prolonged keyboard use and prolonged manual pipetting are the most likely causes of repetitive motion injury at UC Davis. A complex network of smaller ligaments holds each carpal to the next.
Pressure is relatively minimal when the wrist is straight.
Positions of wrist flexion and extension also cause increased stress to the joints between the carpal bones and increased tension to the tendons crossing the wrist. When the body is stressed, tissue damage occurs as a natural process. If adequate recovery time is allowed before the tissues are again stressed, the body tissues rebuild themselves to a stronger level. However, if recovery time is inadequate, symptoms can result. Adequate recovery time will then be needed to again enter the cycle.
