Abstract
Diabetes mellitus (DM) is a metabolic disorder resulting from a defect in insulin secretion, insulin action, or both insulin deficiency in turn leads to chronic hyperglycemia with disturbances of carbohydrate, fat and protein metabolism. As the disease progresses tissue or vascular damage ensues leading to severe diabetic complications such as retinopathy, neuropathy, nephropathy, cardiovascular complications and ulceration. The aim of this study was to investigate the effect of low-frequency ultrasound in the treatment of diabetic foot ulcer. Forty men and women(study group was 9 females and 11 males)and(control group was 6 females and 14 males) with diabetic foot ulcer were chosen from the inpatient department of vascular and general surgery of Omm Elmasriyen hospital, their ages ranged between 40-60 years. Assessment was done before treatment and after 15, 30, 45, 60 days for a total treatment period 8 weeks to assessment wound surface area by using computer analysis program ( image j version) and assessment ulcer volume which was using a syringe filled with normal saline and also assessment the ulcers by photographic camera at the beginning and at the end of the study. Patients were divided into two equal groups in numbers. group A was the study group and was treated through conservative treatment of wound care with ultraviolet c radiation therapy and low frequency ultrasound therapy, group B was the control group and was treated through conservative treatment of wound care with ultraviolet c radiation therapy 3 times/weeks for 8 weeks of both groups. The results of the present study revealed that low frequency US significantly improved ulcer healing favor to study group, significant reduced of ulcers to the study group at post 15 days, post 30 days, post 45 days and post 60 days the percentage of improvement in wound surface area was 63.3% after 60 days of LFU treatment (Post-treatment) of study group when compared with before LFU treatment pre-treatment
