Abstract
Objective: To evaluate the efficacy of various energy densities of shock wave therapy on wounded rats and to compare their effects. Design: Randomized, controlled trial. Animals: sixty rats; adult, male, and albino type. Interventions: A wound area of six-centimeter square was performed post-anesthesia after that rats were divided into group (A) (Twenty rats, six hundred shocks per session for six sessions, energy density per shock 0.1 millijoules/mm(2)), group (B) (Twenty rats, six hundred shocks per session for six sessions, 0.05 milli joules/mm(2)) and group (C) (Twenty rats, as control group or shockwave in shutdown mode group). Measures: At the end of the 1st and 2nd weeks, wound surface areas and contraction rate were measured by planimeter. Results: By the end of 1st and 2nd weeks, group (A) and (B) showed more significant shrinking in wounded area (WSA) in addition more significant increase in contraction rate, when compared respectively to those measures in group (C) in addition more better results in group (A) was found in comparison to group B Conclusion: Shock Wave Therapy has facilitating effect on wound healing at both energy density levels; 0.1 milli Joules /mm(2) and 0.05 milli Joules/mm(2), in addition, more positive healing results were gained at 0.1 milli Joules /mm(2) energy density.
