comparison between the effects of different frequencies of ultrasonic cavitation on abdominal adiposity and female hormones in polycystic ovarian syndrome

Conditions: Polycystic Ovary Syndrome

Summary: thirty women diagnosed with pcos had participated in the study. they suffered from amenorrhea or oligo-menorrhea and subcapsular follicles. their ages were from 20-35 years. their bmi was from 30 - 35 kg/m². their waist/hip ratio was ˃ 0.85. their lh/fsh ratio was ≥ 1.5. they were recruited randomly from the outpatient clinic of gynecology in minya governorate hospital. they were randomly assigned into two groups equal in number: (a and b); group a (n=15) received 40000hz ultrasound cavitation, group b (n=15) received 2600hz ultrasound cavitation. treatment time was 30 minutes /sessions, 3 times/ week for two months. both groups (a and b) received a low caloric diet (1200 kcal/day). all participants had their medical treatment as prescribed by the physician.

participants in both groups were told to follow a low calorie diet (1200 kcal/day) tailored to their specific needs (low in fat (15%), high in complex carbs (55%), and adequate in protein) (30 percent ) (11). the application procedure of ultrasound cavitation for both groups (a and b):- * each participant in both groups (a and b) received instructions on the treatment techniques as well as the benefits of the usfc. * to improve lymphatic drainage, each subject was encouraged to consume one liter of water before and after the therapy sessions. * each participant was urged to empty her bladder before beginning each treatment session so order to remain comfortable and relaxed throughout the session. * from a standing position, each participant's abdomen was divided transversally into three sections; see fig (1) 1- part i: from the xiphoid process to 3cm above the umbilicus, 2- section ii: from 2cm below the umbilicus to the pubic bone, and vertically to the linea alba, each part was separated into right and left segments, resulting in a total of 6 abdominal segments. * part iii: 3cm above the umbilicus to 2cm below the umbilicus * after washing the skin on the anterior abdominal wall with alcohol, a conducting medium (gel) was placed to the ultrasonic instrument's cavitational head. * the gadget was turned on, a 30-minute timer was set, and the intensity was gradually increased. * the cavitation head then moved extremely gently in a small circular motion on each abdomen section for 5 minutes. * after completing the ultrasonic application to the six regions of the abdomen, the skin was cleansed with a piece of cotton. for group (a): 40000 hz ultrasound was delivered for 30 minutes, 3 times/week for 2 months. for group (b):26000 hz ultrasound was delivered for 30 minutes, 3 times/week for 2 months
