Effect of Whole Body Vibration on Obese Hypothyroid Postmenopausal Women

Abstract Background: This study was conducted to determine the effect of whole body vibration on 30 obese hypothyroid postmenopausal women. Aim of Study: The aim of this study was to investigate the effect of whole body vibration on hypothyroidism in postmenopausal women. Material and Methods: Thirty obese postmenopausal women were participated in this study. They were referred from outpatient clinic of physical therapy department in Elshiekh Zayed Specialized Hospital. Their ages were ranged from (50-55) years old with a mean value 51.83±1.7 years and their (BMI) was ranged from (30-35) kg/m2 with a mean value 31.6±1.62kg/m2. All patients were clinically diagnosed as hypothyroidism and all of them were receiving hypothyroid medical treatment in the form of thyroxine tablets (2-3 tablets per day). All participants were randomly divided into two groups equal in number, control group (group A) and study group (group B). Patients in group (A) were treated by thy-roxine tablets described by the physician and a low caloric diet program for 8 weeks, while patients in group (B) were treated by thyroxine tablets and the same low caloric diet program as group (A) in addition to performing a whole body vibration training machine for 40 minutes, 3 sessions per week for 8 weeks. The session of WBV was consisted of 40 minutes, started with low frequency (20 HZ), then increased frequency gradually up to 100 Hz and then ended with low frequency (20 HZ). All patients in both groups (A&B) were evaluated by measuring body weight, Body mass index (BMI), Waist hip ratio (WHR), total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, TSH, FT3, FT4 before starting and after the end of the treatment program. Results: The results showed a highly significant (p-value £0.0001) decrease in body weight, Body mass index, Waist hip ratio, total cholesterol, triglycerides, low-density lipoprotein and TSH hormone with a significant (p-value £0.0001) increase in high-density lipoprotein, FT3 and FT4 after treatment in both groups. Yet, these changes were more pronounced and statistically significant in the study group when compared to the control group. Conclusion: It could be concluded that whole body vibra-tion training combined with low caloric diet program with thyroxine tablets is much better than using only a low caloric diet program with thyroxine tablets in treating obese postmen-opausal women with hypothyroidism. Thus, whole body vibration training has a great and beneficial effect on hypothy-roidism in obese postmenopausal women. It gives amazing results and noticeable changes.
