Abstract

A technique and apparatus for muscle strength testing. A gauged pressure sensitive device is applied to the muscle while pressure to the muscle is gradually increased to a point just short of the muscle breaking point. The applied pressure at this pre-breaking point is measured to provide an objective measure of muscle strength. The gauged pressure sensitive device may be an air bag connected to a pressure gauge, the air bag being placed between the pressure source and the muscle, thereby allowing the applied pressure to be measured.

Claims

1. An apparatus for objectively evaluating the amount of pressure needed to reach the pre-breaking point of a muscle of an individual during the course of a muscle strength test comprising:

first pressure sensitive means for sensing the pressure applied to a muscle;

second pressure sensitive means for sensing the pressure applied to a muscle;

pressure responsive means for indicating the pressure sensed by said first or second pressure sensitive means; and

means interconnecting said first and second pressure sensitive means to said pressure responsive means for selectively interconnecting said first or said second pressure sensitive means to said pressure responsive means.

2. The apparatus of claim 1, wherein said first pressure sensitive means has a greater surface area to be in contact with said muscle than said second pressure sensitive means for testing larger muscles than said second pressure sensitive means.

3. The apparatus of claim 1 including means for mounting said first and second pressure sensitive means to the hand of the person performing said muscle test.

4. The apparatus of claim 1, wherein said first and second pressure sensitive means are fluid filled bags and said selectively interconnecting means is a valve.

5. A muscle testing glove comprising:

a glove,

first pressure sensitive means permanently mounted on the exterior palm surface of said glove;

second pressure sensitive means adapted to be removably mounted over the distal palmer surface of one of the glover wearer'"'"'s fingers;

pressure responsive means mounted on the exterior dorsal surface of said glove for indicating the pressure sensed by said first or second pressure sensitive means;

means interconnecting said first and second pressure sensitive means and said pressure responsive means and mounted on the exterior dorsal surface of said glove for selectively interconnecting said first or second pressure sensitive means to said pressure responsive means.

6. The muscle testing glove of claim 5, wherein said first pressure sensitive means has a greater surface area to be in contact with said muscle than said second pressure sensitive means for testing larger muscles than said second pressure sensitive means.

7. The muscle testing glove of claim 5, wherein said first and second pressure sensitive means are fluid filled bags and said selectively interconnecting means is a valve.

8. The muscle testing glove of claim 5 wherein said glove has four finger portions and two hole portions, said hole portions located on said glove along opposed lateral edges of said palm surface to permit the glove to be worn on either the right or left hand of said wearer wherein the thumb of the wearer fits in one of the two holes.
