System and apparatus for providing quantified hand analysis
First Claim
1. A system for non-invasive analysis of a person'"'"'s wrist complex comprising:
- a fixture with three or more contact points, wherein the three or more contact points are positioned such that forces applied thereto are balanced and wherein such contact points are configured to minimize the side loads.

Abstract
A non-invasive system and method of determining the presence or absence of neural, muscular, soft tissue, bone or joint damage to a person'"'"'s hand and/or wrist. The system includes a plurality of contact points, one of which is engageable by the person'"'"'s thumb and two of which are engageable by other digits of the hand, at least one of the other digits being innervated by the ulnar nerve. Force detectors are operatively connected to at least two of the contact points for measuring the quantity of force applied through respective contact points as the thumb and other digits are brought toward each other in a natural gripping motion. The measured forces are displayed for analysis of the hand and/or wrist.

17. A method of determining the presence or absence of neural, muscular, soft tissue, bone or joint damage to the wrist complex comprising the steps of:
-
(a) engaging contact points with at least one digit innervated by the ulnar nerve and at least one digit innervated by the median nerve, wherein the contact points are configured to transmit forces normal to their surface;
(b) applying force on the contact points with said digits; and
(c) measuring the force applied to at least two of said contact points to provide quantifiable outputs therefor, wherein the outputs are used to diagnose wrist complex diseases and injuries. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
