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.).

Beigthon score
The test consisted of the abduction of the thumb to the forearm, the knee hyperextension above 10 degrees, the extension of the metacarpophalangeal joint in the 5th finger above 90 degrees, the elbow hyperextension above 10 degrees, and the placing flat hands on the floor. Each positive test scored 1 point.
Time frame: Before the main test of muscles flexibility and whole-body vibration training
Straight Leg Raise Test
The participant laid in a supine position. The researcher 1 controlled the position of the participant and raised their lower extremity with the knee extended to the first resistance of the hamstring. The researcher 2 assessed the range of hip flexion with an inclinometer, which was placed 10 cm proximally to the patella.
Time frame: Twice - before and after 2-weeks of the whole-body vibration training
