Description

<p>The purpose of this study is to elucidate the variability in the Semmes-Weinstein monofilament test (SWMT). In this study, we measured the human hand motion during the manual control of the monofilament and compared the velocity of the hand motion and the contact angle between the monofilament and a simulated skin surface. We measured the human hand motion during the SWMT and analyzed both the velocity of the hand motion and the contact angle between the monofilament and a target disk substituting for the skin surface. These results show that the accuracy of the SWMT is dependent on the human hand motion (velocity of hand motion and/or compression angle). In future work, we plan to find a smart solution to minimize the variability in this test and develop a new method that uses tactile sensibility.</p>
