Whole-Body Vibration and Balneotherapy in Chronic Low Back Pain

Participants receive 20-minute balneotherapy sessions involving full-body immersion in thermal-mineral spring water at a therapeutic spa facility. Sessions are conducted five days per week over a three-week period. Water temperature and mineral content are standardized according to institutional protocols. The intervention is designed to provide analgesic, anti-inflammatory, and muscle-relaxant effects through thermally induced vasodilation and neuromuscular modulation.

"Participants perform whole-body vibration (WBV) exercises using the Compex Winplate platform (Uniphy Elektromedizin GmbH \& CoKG), certified under ISO 9001:2000 and DIN EN ISO 13485:2003. The exercise protocol includes static squats, dynamic squats, bridge exercises, dynamic weight shifting, and toe raises. Vibration is applied at a frequency of 30-40 Hz and amplitude of 2-4 mm for 40-60 seconds per set, with two sets per session and a 3-minute rest between sets. WBV is applied following a standardized exercise program, and the full intervention is delivered five days per week for three weeks."
