Statistical Analysis

A matched sample paired t-test was used to calculate the difference in responses between the before and after measures for pain, stiffness and range of motion for the 94 hips, including the subgroup of twenty patients who before starting Prolotherapy were told there were no other treatment options and the eight patients told by their medical doctor(s) there was no other treatment option but surgery. Using the paired t-test, all p values for pain for all subgroups reached statistical significance at the p<.0001 level. For the 94 hips, the p values for pain, stiffness, and range of motion all showed statistically significant improvements at the p<.0001 level.
