Bracers (patients 12-17) demonstrated a greater absolute mean change in surface area (12.33 cm2) and media pressure (54.17 gms/cm2) compared to releasers (patients 1-11). (The negative and positive numbers indicate direction of change along the x and y axis). Four distinct ∆X∆Y patterns emerged from the Cuernavaca study: (1) +∆X,-∆Y; (2) -∆X,+∆Y; (3) -∆X, -∆Y; (4) +∆X,+∆Y. Using these ∆X∆Y patterns the following null hypothesis was proposed: ∆X∆Y patterns occur randomly (Ha = ∆X∆Y patterns are due to insole therapy).

This null hypothesis was tested for level of confidence using the Chi-Square (X2) test:

 

Where Ni are the observed frequencies in each pattern and ni are the expected frequencies in each pattern if based on chance occurrence alone.

The results of the Chi-Square (X2) test (See Table 4 below) rejects the null hypothesis.
