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. ## Detailed 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. ## Eligibility - **Minimum age:** 18 Years - **Maximum age:** 25 Years - **Sex:** ALL - **Healthy Volunteers:** Yes ``` Inclusion Criteria: * Female students * BMI ≥ 30 * Aged from 18 to 25 years old Exclusion Criteria: * Pregnancy * Musculoskeletal disorders * History of spinal surgery * Epilepsy * Medications that could affect the musculoskeletal system * Performing regular exercise of more than 3 times a week * Metal plates in the body * Ligament sprain * Medical history such as cardiovascular disease, or diabetes mellitus ``` ## Arms - **Group A (WBV Group)** (EXPERIMENTAL) — 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 - **Group B (Sham WBV Group)** (SHAM_COMPARATOR) — They will receive the same intervention while the device turned off for 4 minutes, 2 session/ week for 6 weeks. ## Interventions - **Whole body Vibration** (DEVICE) — 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 - **Sham Whole body vibration** (OTHER) — They will receive the same intervention while the device turned off for 4 minutes, 2 times /week for 6 weeks. ## Primary Outcomes - **Sorensen Test** _(time frame: 6 weeks)_ — The participants will be asked to lie prone on the treatment table with their hips and knees extended and their arms crossed over their chest, then placing a strap over the pelvis, knees and ankles for support. Then they will be instructed to raise their upper body off the table until their back were parallel to the floor ## Secondary Outcomes - **Trunk flexor endurance Test** _(time frame: 6 weeks)_ - **Single leg test** _(time frame: 6 weeks)_ - **Dynamic balance** _(time frame: 6 weeks)_ ## Locations (1) - Nesma Morgan Allam, Giza, Egypt ## Recent Field Changes (last 30 days) - `status.overallStatus` — added _(2026-05-12)_ - `status.primaryCompletionDate` — added _(2026-05-12)_ - `status.completionDate` — added _(2026-05-12)_ - `status.lastUpdatePostDate` — added _(2026-05-12)_ - `design.phases` — added _(2026-05-12)_ - `design.enrollmentCount` — added _(2026-05-12)_ - `eligibility.criteria` — added _(2026-05-12)_ - `eligibility.minAge` — added _(2026-05-12)_ - `eligibility.maxAge` — added _(2026-05-12)_ - `eligibility.sex` — added _(2026-05-12)_ - `outcomes.primary` — added _(2026-05-12)_ - `outcomes.secondary` — added _(2026-05-12)_ - `armsInterventions.arms` — added _(2026-05-12)_ - `armsInterventions.interventions` — added _(2026-05-12)_ - `sponsor.lead` — added _(2026-05-12)_ - `results.hasResults` — added _(2026-05-12)_ - `locations.nesma morgan allam|giza||egypt` — added _(2026-05-12)_ --- *Canonical: https://parkinsonspathways.com/agent/trials/NCT06202365.md* *Source data (authoritative): https://clinicaltrials.gov/study/NCT06202365* *This page is a raw mirror with no AI summary, no editorial enrichment, and no Parkinson's-specific filtering.*
