Strong reassurance and smoking cessation may be useful. Muscle cramps in the hands, similar to writer's cramp, may awaken patients several times during the night. Occasionally, calcium supplements help prevent the cramps. This increase is likely due to the widespread use of computers and other technical devices requiring repetitive motion of the hand. Why overuse syndromes affect only some persons is unknown.
Treatment includes simple measures such as rest, splinting, and moist heat.
Stretching and isometric strengthening exercises help restore mobility. Recurrence is prevented by avoiding the activity that provokes discomfort and by modifying the work or home environment. Hand function should be assessed during the physical examination. The presence or absence of hand deformities is not a good indicator of hand function. Consultation with an occupational therapist may be useful.
