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.).

Primary outcomes

  1. Beigthon score

    Time frame: Before the main test of muscles flexibility and whole-body vibration training

    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.

Secondary outcomes

  1. Straight Leg Raise Test

    Time frame: Twice - before and after 2-weeks of the whole-body vibration training

    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.

Other outcomes

  1. Popliteal Angle Test

    Time frame: Twice - before and after 2-weeks of the whole-body vibration training

    The participant laid in a supine position with the hip flexed to 90˚ and the extended untested lower extremity. The researcher 1 controlled this position with a goniometer. In this position, the participant had to straighten his knee. The researcher 2 assessed the popliteal angle with an inclinometer, which was placed 10 cm below the tibial tuberosity

  2. Modified Thomas Test

    Time frame: Twice - before and after 2-weeks of the whole-body vibration training

    The modified Thomas test was used to assess the flexibility of One-JHF and Two-JHF. During One-JHF test, the participant laid in a supine position with the pelvis close to the edge of the table. The untested lower extremity was flexed at the hip and knee joint. The researcher 1 controlled and stabilized the participant's position. The tested lower extremity was placed in a relaxed position behind the table. The researcher 2 assessed the range of hip extension/flexion with the inclinometer, which was placed 10 cm proximally to the patella. During the Two-JHF test, the participant was in the same position. The researcher 1 assessed the range of knee flexion with the inclinometer, which was placed 10 cm below the tibial tuberosity
