Effects of Whole-Body Vibration and Pilates on Pain, Dynamic Balance, and Functional Performance in Chronic Non-Specific Low Back Pain

Chronic non-specific low back pain (CNSLBP) affects pain, balance, and functional ability. This randomized clinical trial aims to compare the effects of whole-body vibration (WBV) and Pilates, both combined with conventional physiotherapy, on pain, dynamic balance, and functional performance. A total of 68 participants aged 18-40 years will be randomly assigned to either a WBV group or a Pilates group. Both groups will receive treatment three times per week for four weeks. Outcomes will be measured using the Visual Analog Scale (pain), Y-Balance Test (dynamic balance), and Progressive Isoinertial Lifting Evaluation (functional performance). The results will help determine which intervention is more effective for managing CNSLBP and guide evidence-based rehabilitation practices.

Inclusion Criteria: 1. Male and Female (18-40 years age) 2. Pain lasting for more than 12 weeks(determined by patient history) 3. Pain scores (VAS) ranging from 3 to 8 points 4. Pain located between T12 and gluteal folds(determined via palpation) 5. Not having attended Pilates for low back pain for atleast 6 months prior to enrollment Exclusion Criteria: 1. History of spinal surgery, fractures, tumors, infections, or inflammatory spinal disease. 2. Pregnant or lactating( strongly contraindicated for whole body vibration due to potential fetal risk and pelvic instability) 3. Radicular pain, nerve root compression or neurological deficits. 4. Medical comorbidities (e.g cardiovascular, neurological, endocrine or metabolic disease)(5). 5. Physical limitations (e.g. orthopedic or rheumatic diseases, muscular injury, fibromyalgia, or pain)that could affect their ability to perform the Pilate exercises. 6. Participants whose weight exceeds 150kg ( that's the maximum weight bearing capacity for WBV)
