Differential diagnosis | Hyperthyroidism |
Physiologic tremor is a tremor or trembling of a limb or other body part. The recorded frequency is in the range of 8-12Hz. It occurs in normal individuals, especially when they are stressed by anxiety or fatigue. It is therefore common in sports such as rock-climbing where it is known by names such as Elvis leg or sewing machine leg. [1] It may occur in an enhanced form as a pathological symptom of conditions such as hyperthyroidism or stimulants such as caffeine. [2]
Elvis leg: Uncontrollable shaking in the lower leg caused by fear and fatigue. Best prevented by relaxing and dropping your heels when standing on footholds
