A method of measuring a change in neurological and/or muscular performance of a subject may include attaching an attachment to a subject. The subject may then be directed to perform a motion. A first force imposed by the subject on the attachment and/or a first motion of the attachment is sensed. The subject's first response may then be compared to a second response to determine a change in the subject's neurological and/or muscular performance.
