Effect of ultrasound associated with calendula gel on restorative activity in experimental muscular injuries - doi: 10.4025/actascihealthsci.v32i2.4626

Abstract

Several techniques have been proposed as treatment for muscular injuries, and therapeutic ultrasound is one of the most used. Besides the effects of ultrasound, it also facilitates drug flow trough the tissues (phonophoresis). Calendula is a phytotherapic which presents healing elements, popularly used on injury treatments. The objective of this study was to evaluate ultrasound effectiveness, phonophoresis, and the influence of the topic application of the gel with Calendula officinalis extract, in the recovery from experimental muscular injury in rats. After the injured front tibial muscle was treated during five days, a histological analysis of the muscle was performed and the injury area was determined. The results indicated that all the ultrasound/Calendula-treated groups presented better evolution in the injury, sinasce they presented more fibroblasts, neovascularization and myoblasts in relation to the control group. As to the injured area, only the group in which the ultrasound was added to Calendula presented a significantly smaller area. In all, the obtained data demonstrate that in the experimental model studied, phonophoresis was more indicated for muscle injury treatment.
