An attempt at objective and subjective evaluation of the therapeutic efficacy of focused and radial shockwave applied to symptomatic heel spur.

Abstract

PURPOSE:

The experiment was designed to evaluate and compare the efficacy of focused shockwave and radial shockwave in symptomatic heel spur treatment. Postural balance tests were used to ensure the objectivity of evaluations.

METHODS:

Forty three patients with symptomatic heel spur were divided into two comparative groups that received respectively focused shockwave therapy (the FSWT group; 2000 impulses, 4 Hz, 0.4 mJ/mm2) and radial shockwave therapy (the RSWT group; 2000 impulses, 8 Hz, 5 bars + 2000 impulses, 8 Hz, 2.5 bars). Each patient received 5 treatments at weekly intervals. Before therapy started and 1, 3, 6 and 12 weeks after it ended, the intensity of pain experienced by the patients was assessed and static balance tests were performed on a force platform.

RESULTS:

Successive measurements showed that the intensity of all kinds of pain under consideration was decreasing gradually and statistically significantly in both groups. The percentage reduction in pain intensity was similar between the groups. The standard deviation of the COP in the anterior-posterior and medial-lateral directions, 95% confidence ellipse area and COP velocity kept varying throughout the experiment, but in none of the groups changes were statistically significant.

CONCLUSIONS:

Focused shockwave therapy and radial shockwave therapy improve the well-being of patients with symptomatic heel spur significantly and comparably. Posturography cannot deliver unambiguous data for tracking changes that the two therapies induce in these patients.
