Use of hand tools may casue cumulative
trauma disorders ("CTD's").
CTD's, when using hand tools, tend to
affect the upper extremities. Factors which
may increase the risk of developing a CTD
include:
1 . High frequency of the activity.
2 . Excessive force, such as gripping,
pinching, or pressing with the hands
and fingers.
3 . Extreme or awkward finger, wrist, or
arm positions.
4 . Excessive duration of the activity.
5 . Tool vibration.
6 . Repeated pressure on a body part.
7 . Working in cold temperatures.
CTD's can also be caused by such activities
as sewing, golf, tennis, and bowling, to
name a few.
Pain, tingling, or numbness in the shoulder, forearm, wrist,
hands, or fingers, especially during the night, may be early
symptoms of a CTD. Do not ignore them. Should you
experience any such symptoms, see a physician
immediately. Other early symptoms may include vague
discomfort in the hand, loss of manual dexterity, and
nonspecific pain in the arm. Ignoring early symptoms and
continued repetitive use of the arm, wrist, and hand can
lead to serious disability.
