About

Obesity is a global public-health issue, with rising incidence and prevalence, significant expenditures, and poor results. Obesity has become a worldwide epidemic in both developed and underdeveloped countries. A body mass index (BMI) of 30 kg/m2 is required for class I obesity, a BMI of 35 - 39.9 kg/m2 is required for class II obesity, and a BMI of 40 kg/m2 is required for class III obesity (morbidly obese). Obesity will be the likely situation for the majority of the adult population during the next two decades due to an abundance of calorie-rich food and apathy toward exercise.

Full description

Obese and overweight young people swayed at a higher rate than people of normal weight. Two hypotheses have been offered to explain the negative effect of weight on balance control. The first is decreased plantar sensitivity as a result of hyper-activation of plantar mechanoreceptors caused by the constant pressure of supporting a heavy burden. The second theory is that there is a higher mechanical demand owing to the big body mass itself, as well as a non-negligible amount of body mass further away from the axis of rotation (i.e., ankle joint in an inverted pendulum model) that creates a higher gravitational torque. As a result, in order to maintain an upright posture, the gravitational torque that accelerates the body must be opposed by muscle torques.

WBV is a mechanical stimulation characterized by oscillatory motion supplied from a platform to the entire body. The current devices employ two distinct systems: (a) a vertical vibration, in which the entire plate oscillates uniformly up and down with only a vertical translation; and (b) reciprocating vertical displacements on the left and right sides of a fulcrum, which increases the lateral accelerations. WBV training includes biomechanical characteristics such as body position, amplitude, frequency, magnitude, and duration.

---

50 participants in 2 patient groups

Group A (WBV Group)

Experimental group

Description:

A vibrating platform (WBV) will be used in this study with 6 training exercises for 4 minutes, 2 times /week for 6 weeks. Feet should be parallel at shoulder width apart and knees hold constant. WBV sessions were conducted from low to medium-vibration mode

Treatment:

Device: Whole body Vibration

Group B (Sham WBV Group)

Sham Comparator group

Description:

They will receive the same intervention while the device turned off for 4 minutes, 2 session/ week for 6 weeks.

Treatment:

Other: Sham Whole body vibration
