An objective study of the dimensions of the ischial pressure point and its correlation to the occurrence of a pressure sore.

A simple non-invasive technique has been used to study the dimensions of the ischial pressure point in normal and paraplegic individuals. The same technique charts the surface area of the gluteal impression. The data obtained in these two groups of patients (normal and paraplegic) have been analysed to see if it is possible to predict the greater susceptibility of certain individuals to suffer from pressure sores over the ischial tuberosity.
