The Influence of Whole-body Vibration Training on Postural Stability in People With Generalized Joint Hypermobility

The Influence of Whole-body Vibration Training on Postural Stability in People With Generalized Joint Hypermobility

The aim of this study was the assessment of muscle flexibility after 2-weeks of whole-body vibration (WBV) training in people with generalized joint hypermobility (GJH). The study included 33 participants aged 22-25 years. 12 participants were classified into the GJH group and 21 into the control group (CG). The study included the Beighton score and muscle flexibility tests: straight leg raise test (SLR), popliteal angle test (PA), and the modified Thomas test. These tests were performed before and after the short-term WBV program, which consisted of six sessions (frequency: 15 Hz and 30 Hz, amplitude 3 mm, 3 trials x 3 min.).
