Tremor resists quantification of the ordinary level of clinical
observation, where an objective record of tremor severity is desirable to
evaluate patients' statements about effects of medication or
pathophysiological states. The tremometer is an easily made device that
measures amplitude of postural tremor in any radial direction by a graded
series of round holes in which a probe is held and contact (which closes a
circuit with an indicator light) is avoided. The observation of various
types and features of tremor may be aided by the tremometer.
