Effects of Whole-Body Vibration and Cervical Stabilization With Core Stabilization in Young Adults With Non-Specific Low Back Pain

This study aims to investigate the immediate effects of three intervention approaches in young adults with nonspecific low back pain. Participants will be randomly assigned to one of three groups: core stabilization exercises, whole-body vibration combined with core stabilization exercises, or cervical stabilization combined with core stabilization exercises. Outcomes will be assessed before and immediately after the intervention. The study will evaluate trunk motor control, pain intensity, pressure pain threshold, trunk muscle endurance, and balance. The purpose is to compare the immediate effects of these approaches and determine whether adding whole-body vibration or cervical stabilization to core stabilization produces additional benefits.

Inclusion Criteria: * Age between 18 and 30 years. * Low back pain intensity of at least 3/10 on the Numeric Rating Scale. * Low back pain symptoms for at least 6 months. * Ability to understand and follow verbal instructions. * No major neurological deficit. * No physiotherapy for low back pain within the previous 6 weeks. Exclusion Criteria: * Low back pain with a specific etiology identified by a physician. * Neurological, vestibular, rheumatological, or serious musculoskeletal disorders affecting balance or motor control. * Use of medications that may affect balance or have potential neurotoxic effects. * Degenerative diseases. * Indication for surgical intervention. * History of fracture or surgery within the previous 2 years.
