Whole-Body Vibration and Postural Stability in Painful HSD

This randomized controlled trial aims to investigate the effects of adding whole-body vibration training to a conventional exercise program on postural stability and pain in painful women with hypermobility spectrum disorder. Participants are randomly allocated to conventional exercise or conventional exercise plus whole-body vibration groups and complete a 6-week supervised intervention program.

Inclusion Criteria: Diagnosis of hypermobility spectrum disorder (Beighton score ≥4/9) Female participants aged 18-45 years Presence of musculoskeletal pain for at least 3 months Exclusion Criteria: Pregnancy Presence of a cardiac pacemaker Presence of an implanted brain stimulator Presence of a metal implant Acute or chronic arthritis Active malignancy Acute infection Initiation of medications that may affect proprioception or postural stability (e.g., antidepressants, antipsychotics, or hypnotics) within the previous 2 months Regular exercise more than 3 days per week Postmenopausal status Orthopedic surgery within the previous 12 months Vertigo Acute painful conditions that would prevent participation in exercise
