<strong>Abstract</strong>: [Objective] The purpose of this study was to investigate the relationship between<br />

physiological tremor and finger dexterity.<br />

[Method] Position and <strong>for</strong>ce tremors were assessed with a test of pinching precision respectively.<br />

Position tremor was measured from a position of pinched object with an accelerometer and a<br />

laser displacement-transducer. Force tremor was measured to match a finger tip <strong>for</strong>ce to 1N with<br />

a load cell. A target line was displayed on a screen of an oscilloscope. Position and <strong>for</strong>ce<br />

fluctuations were evaluated with the standard deviation (SD) of a lower frequency component<br />
