1. A system for measuring and inputting range of motion data to a computer, comprising:
- goniometer means having a movable member pivotally connected to a reference member for producing an analog range of motion signal representative of the position of said movable member relative to said reference member, each of said movable member and reference member having clear center portions surrounded by opaque edges;
a plurality of switch means carried by said goniometer means for producing a plurality of control signals;
interface means including an analog to digital converter means for receiving said range of motion signal and for converting said signal to digital range of motion data, said interface means also for receiving said plurality of control signals for controlling the input of said digital range of motion data to the computer remote from said goniometer means.

Abstract
A system for measuring an inputting range of motion data to a computer comprises a goniometer for measuring range of motion and for producing a range of motion signal from those measurements. A plurality of switches are carried by the goniometer for producing control signals. An interface device receives the range of motion signal and digitizes that signal to produce range of motion data. The interface device also receives the control signals which are used to control the input of the range of motion data to the computer.

8. A system for measuring and inputting range of motion data to a computer having a screen for displaying the position of a cursor representative of the location in the computer'"'"'s memory where range of motion data may be stored, said system comprising:
-
goniometer means having a movable member pivotally connected to a reference member for producing an analog range of motion signal representative of the position of said movable member relative to said reference member; a plurality of switch means carried by said goniometer means for producing first and second control signals; interface means including an analog to digital converter for receiving said range of motion signal and for converting said signal to digital range of motion data, said interface means also receiving said first control signal and inputting said first control signal to the computer for controlling the position of the cursor, said interface means also receiving said second control signal and inputting said second control signal to the computer to control the input of said range of motion data to the computer.
