The traditional method of hand function assessment uses a mechanical or electronic goniometer placed across the joint of interest to measure the range of joint movement. Mechanical goniometers are imprecise and lack the ability to provide a dynamic measurement; electronic goniometers are expensive and cumbersome to use during therapy. An alternative to the goniometric based assessment is to use inertial motion sensors to monitor the hand movement\u2014these can be incorporated in a glove. In this paper, we present the design of an instrumented glove equipped with Magnetic, Angular Rate and Gravity (MARG) sensors for the objective evaluation of hand function. The instrumented glove presented in this paper is designed to assess the range of movement of the hand and also monitor the hand function during the course of hand rehabilitation. Static and dynamic calibrations were performed for the Euler angles calculated from the MARG sensors. The results are also presented for physiological flexion\/extension of the wrist (relative roll), flexion\/extension of elbow (relative pitch), and internal rotation\/external rotation (relative yaw). The static calibration results gave mean absolute errors of 4.1\u00b0 for roll, 4.0\u00b0 for pitch, and 4.6\u00b0 for yaw. From the dynamic calibration, the speed of response to a step change gave a convergence time of 0.4 s; sinusoidally oscillating movement gave good tracking at 0.2 Hz but exhibits overshoot errors at higher frequencies which were tested to be 1 Hz. We present the results of the calibration of the instrumented glove (one sensor pair measuring one joint angle) measuring anatomical joint angles\u2014mean absolute errors during static calibration: 6.3\u00b0 for a relative roll (wrist flexion\/extension), 5.0\u00b0 for relative pitch (elbow flexion\/extension), and 4.5\u00b0 for relative yaw (shoulder internal rotation\/external rotation). The experimental results from the instrumented glove are promising, and it can be used as an alternative to the traditional goniometer based hand function assessments.<\/jats:p>","DOI":"10.1063\/1.5038601","type":"journal-article","created":{"date-parts":[[2018,10,3]],"date-time":"2018-10-03T17:52:51Z","timestamp":1538589171000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":18,"title":["An instrumented glove for monitoring hand function"],"prefix":"10.1063","volume":"89","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7909-3099","authenticated-orcid":false,"given":"A.","family":"Mohan","sequence":"first","affiliation":[{"name":"Department of Bioengineering, Christian Medical College Vellore 1 , Vellore, India"},{"name":"Department of Biotechnology, Indian Institute of Technology Madras 2 , Chennai, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Tharion","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Christian Medical College Vellore 3 , Vellore, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.
