Abstract
Physiologic tremor hampers the ability of students to learn microsurgical technique. An understanding of normal tremor both as to origin and methods of control would be of help. Physiological tremor arises from both mechanical and neuromuscular sources and is made worse by a number of factors. The “size principle of motoneuron recruitment” is an important physiologic consideration, and the use of biofeedback techniques enables the student to confirm his understanding of the principle. Knowledge of the factors which aggravate physiological tremor allows the microsurgeon to control his own tremor both in the laboratory and in the operating room.
