Filed:

May 9, 2002

Appl. No.:

10/142331

Inventors:

Richard Berger - Rochester MN, US
Fredrick Schultz - Rochester MN, US
Lawrence Berglund - Rochester MN, US

International Classification:

A61H001/00

US Classification:

128/845000, 601/005000, 601/033000

Abstract:

Disclosed is a method and apparatus for repeatably positioning a forearm at a plurality of angular positions for medical analysis. A forearm of a patient is positioned in a support channel within reach of a rotatable handle. The handle can be locked in a number of angular positions, providing a counteractive force as the handle is rotated. The patient rotates and applies a torque force to the handle at selected rotational angles. The forearm and wrist can be scanned in these locked position, and applied torque can be measured to evaluate joint stability.
