One hundred and ninety consecutive patients with diagnostically confirmed painful calcar calcanei were screened for eligibility criteria. One hundred and twenty-four patients fulfilled all eligibility criteria. Eighteen patients had sensory polyneuropathies, a lesion of the sole skin had ten participants, cortisone treatment up to six weeks before the initial treatment session had eight, eleven patients were medically unstable, and nineteen declined to participate in the clinical trial. The patients were divided by the method of equal randomization into two groups. The first group was designated as the experimental group and had 62 patients treated with shock wave therapy. The second group was selected as the control group; it included 62 patients treated with standard ultrasound therapy. Descriptive statistics of all outcomes for both groups are presented in The results of the analysis of comparisons between experimental and control groups are presented in The results of the ‘pre-post' therapy analysis are presented in Calcification and VAS change were calculated as subtraction, pretherapy, posttherapy, and VAS pretherapy and VAS posttherapy. The results of comparing changes in calcification and VAS, separately between the experimental and control groups are presented in Additionally, we observed the change in the VAS as greatly improved (> = 50), much improved (50 < ×< = 30), somewhat improved (30 < ×< = 10), about the same (10 < ×< = 1), and worse (>1). The change in VAS in both groups is presented in Additionally, we observed the change in the calcification as improved (>0), not improved (<=0)—the change of calcification in both groups presented in The logistic regression was done for calcification improvement, and the results are presented in The relationship between variables for each group was analyzed separately by Pearson's correlations. The results are shown in The analysis of the relationship between two variables, calcification changes and BMI, while controlling by the third variable, age, was done using the partial correlation. The partial correlation was statistically significant and positive with a small degree (The analysis of the relationship between two variables, calcification changes and age, while controlled by the third variable, BMI, was done using the partial correlation. The partial correlation was statistically significant and positive with a medium degree (The analysis of the relationship between two variables, calcification change and VAS change, but controlling a third variable (age, BMI, and therapy duration, separately) was done using the partial correlation. The partial correlation coefficient measures the strength of the linear relationship between two variables after entirely controlling for the effects of other variables. The results are presented in
