Physiological and enhanced physiological tremorLink to article
A fine action tremor is normally present in everyone's limbs. This normal physiological tremor becomes more pronounced (enhanced physiological tremor) during periods of muscular fatigue, fear or excitement, and in certain medical conditions—for example, hyperthyroidism. It is the result of numerous factors including the heart beat, low pass filtering properties of striated muscle, motor neurone firing, and synchronisation by spindle feedback.9 Physiological tremor amplitude can be modulated by temperature and supraspinal influences, such as vision, and also by drugs that interact with β receptors.10
