Abstract
System for measuring the limit of peripheral strength, consisting of method and apparatus for raising the heel of a patient in discreet steps while testing for peripheral strength.
Claims4
Method for measuring the point of heel elevation at which peripheral strength is lost, comprising the steps of:
- (a) placing the patient to be tested in a standing position,
- (b) supporting the balls of both feet,
- (c) supporting both heels on a second surface, which surface is inclined at a selected angle to a flat horizontal first surface,
- (d) changing in successive steps the foot angle between the first surface (on the one hand) and the plane of the balls of the feet and the heels (on the other hand), while measuring peripheral strength at each step, and
- (e) observing the step at which the peripheral strength begins to decrease.

Method for measuring the point of heel elevation at which peripheral strength is lost, comprising the steps of:
- (a) placing the patient to be tested in a standing position,
- (b) supporting the balls of both feet a common horizontal first level,
- (c) supporting both heels on a common second level,
- (d) changing in successive steps the distance between the first level (on the one hand) and the second level (on the other hand), while measuring the peripheral strength of the patient at each step, and
- (e) noting the step at which the peripheral strength begins to decrease.
