This paper shows the impact of shock wave, laser and radiofrequency on diabetic ulcers. A diabetic ulcer is a wound that occurs on the feet of patients with diabetes. The wound is mainly caused by damage to the vascular or nervous system in the foot (damage occurs due to high blood sugar levels), resulting in reduced circulation and reduced sensitivity in that area. Diabetic ulcer is a very serious and life-threatening condition because it often leads to severe complications such as infections and amputations. Statistics show that around 15-25% of diabetics develop an ulcer during their lifetime, and even 50% of them end up with foot amputation. The mortality rate of diabetics with ulcers is 13.1% after 1 year, 49.1% after 5 years and 76.9% after 10 years. Mortality is more frequent if amputation occurs and in older age and if the person also suffers from renal or peripheral arterial disease. The shock wave has been shown to be effective in the treatment of diabetic ulcers. It is easy to use, cost-effective compared to other methods of treatment and does not cause significant side effects. Shock wave therapy is used for tissue healing, and numerous studies have proven its positive effect on diabetic ulcers; the shock wave leads to complete wound healing in diabetics. The laser contributes to reducing the size, promotes the complete healing of the ulcer and plays a major role in reducing pain. It was concluded that laser therapy is a safe option because no studies conducted so far have found any negative effects. Radiofrequency, which stimulates the growth of collagen, has proven to be very effective in the treatment of diabetic ulcers. Research has proven that radiofrequency therapy enables completely healed wounds. In conclusion, the paper presents various researches on the treatment of diabetic ulcers with the mentioned methods.
