“…Because many studies have produced conflicting findings, the clinical use of ultrasound for wound healing is still under investigation [18,19]. Although some investigators saw no acceleration in the repair of wounds with ultrasound treatment [19][20][21], positive results and treatment effects have been reported in studies of ultrasound treatment on tendon injuries, lateral epicondylitis, and wound healing [4][5][6][7]22,23]. In addition, the beneficial effects of laser treatment on wound healing and qualified scar formation have been reported by numerous studies [10][11][12][13][14][15]17,24,25], including our previous study [26].…”

-A randomized controlled study investigated the effects of ultrasound and laser treatments on wound healing in rats. The duration of the inflammatory phase decreased with both laser and ultrasound treatments; however, laser was more effec-tive than ultrasound, with more significant results. The prolifera-tion phase showed, for both treatments, an increase in the level of hydroxyproline and the number of fibroblasts, as well as stimula-tion of the collagen synthesis and the composition. Laser treat-ment was again more effective than ultrasound. The wound breaking strength was significantly higher with both treatments, and no statistically significant difference emerged between the laser and ultrasound groups, although laser treatment provided a much greater increase in the wound breaking strength than ultra-sound. Both treatments have beneficial effects on the inflamma-tory, proliferation, and maturation phases of wound healing. Both can be used successfully for decubitis ulcers and chronic wounds, in conjunction with conventional therapies such as debridement and daily wound caring. However, laser treatment was more effective than ultrasound in the first two phases of wound healing.

“…[92] Studies on the US applications specifically in tendon curing are limited and most of them are animal studies with inconsistent findings. Increases in strength of tensile, energy absorption, mobility, improved collagen fibril alignment, decrease in inflammatory permeate, and scar tissue in tendons have been shown in some trials [93,94] but not others. [95,96] These studies varied mostly in the applied treatment protocols and regimes.…”

Objective: Ultrasound (US) waves have unique characteristics that making them promising option for treatment of different soft tissue injuries particularly wounds. The mechanisms of actions of this technique in the treatment of soft tissue are not fully understood. This paper aimed to comprehensively review the biological interactions and mechanism of action of US waves in the treatment of chronic wounds. Methods: The databases of PubMed (1990PubMed ( -2016, EMBASE (1990EMBASE ( -2016, Web of Sciences (1990), and Google Scholar (1980 were searched using the set terms "US waves" and "wound treatment," "mechanism of action" and "soft tissue injuries," and "biologi8cal interaction." The title and abstract of the collected results were reviewed by two authors, and the relevant papers were selected for further evaluations. Results: The mechanisms of action depend on the US physical parameters as well as exposure factors including duration and injury type. The main mechanisms of US waves for wound healing are enhancing the rate of inflammatory phase, stimulating fibroblasts to secrete collagen, enhancing extensibility of collagen, circulation, pain threshold, enzymatic activity, permeability of cell membrane, and accelerating nerve conduction. Conclusion: The therapeutic effects of US depend on dose (W/cm 2 ) and dosage (frequency of application). Low US frequencies show more therapeutic efficiency in wound healing compared with high frequencies.

“…[8][9][10] The biological studies performed used a broad range of frequency and type of pulse, power, number and time of each ultrasound application, with animals of different ages and species (rats and rabbits mostly, but also dogs and sheep) and human beings. The results of the studies, although with some differences, 11 show vascular alterations, 12 stimulus to the healing of skin ulcers, 13 of tendons, 14 in the formation of fracture callus, 15,16 but not in bone neoformation, 17 with few more recent studies on its effects on longitudinal bone growth and on the epiphyseal plate. [18][19][20] This diversity makes it hard to compare the data and to have a clear understanding of the biological effects of ultrasound, so much so that Wells 3 considered the scientific knowledge about the biological bases of its use "disappointing" and Haar 4 and Leighton 6 considered the need for more investigations in this respect.…”

Objectives: To determine the effects of ultrasound therapy on the femur and tibia growth in young rats. Method: Four-weekold male Ratus Norvegicus totaling 115 animals, divided into four groups, were submitted to ultrasound therapy (0.8 MHz, fixed tube head, continuous pulse, for 10 minutes, once a day, ten times) on the medial face of the right knee, with powers of 0.0 W/cm2 (group G1), 0.5 W/cm2 (group G2), 1.0 W/cm2 (group G3), and 1.5 W/cm2 (group G4). Histological slides of the epiphysis, growth plate and metaphysis and the femoral and tibial length measurements were studied in the sixth, thirteenth and twenty-sixth weeks of life. The data were submitted to factorial analysis of variance according to a one-way layout. Results: No statistically significant bone growth alteration was established between any of the three treated groups and the control group. However, alterations in femoral and tibial growth suggesting a decrease in G4 in relation to G2 and G3 were noted. In G4, histopathological alterations, such as cellular necrosis and post-necrosis bone neoformation were found. Conclusion: According to this study, no statistical evidence of bone growth stimulus or inhibition resulting from the application of ultrasound therapy was found when comparing the treated groups with the control group. Histological alterations regarded as pathological were only observed in G4. Also, smaller significant bone growth was found in G4 compared to G2 and G3. Level of Evidence: Level II, cross-sectional study.
