Efficacy of ultrasound therapy combined with cryotherapy in pain management and rehabilitation in patients with Achilles tendinopathy: a retrospective observational study

Background. Achilles tendinopathy (AT) is characterized by pain, reduced performance, and swelling in and around the tendon. The aim of our study was to evaluate and compare the effects of ultrasound therapy alone or associated with cryotherapy, delivered through cryoultrasound, in patients with subacute AT. Methods. We analyzed retrospectively amateur runner patients who run at least 3 times a week, with medical and ultrasound diagnosis of subacute AT of the midportion. All patients underwent 10 sessions of ultrasounds’ therapy with qmd® ultrasound cryo and a therapeutic exercise with stretching and eccentric exercises. The Cryo-Ultrasound Group (CUG, 15, 8M and7/F), during the ultrasound treatment, underwent a session of cryo-ultrasound therapy. The Ultrasound Group (UD, 15, 7M and 8F) only performed ultrasound therapy Results. All evaluations performed show significant improvement over time in both groups. The CUG shows at T1 a greater increase in pain and function compared to the UG. Friedmann’s repeated measures analysis shows that both groups improved when assessed separately over time. From the subsequent post hoc analysis, a statistically significant difference is highlighted between the values evaluated at T0 and T3. Conclusions. The possible simultaneous delivery of the two treatment modalities, in patients suffering from tendinopathies, therefore represents a good possibility of synergistically exploiting their therapeutic actions. Future studies with a larger patient sample and longer follow-up are also needed to better evaluate the benefits of this treatment.
