An interventional study of whole-body vibration in Hip Dislocation, sponsored by Seoul National University Hospital. Recruiting at 1 site in Korea, Republic of. Open to participants aged 5 Years to 15 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2023-06-22.
Sponsored by Seoul National University Hospital · Not applicable, Interventional, and Prevention
This clinical trial(prospective, pilot study) is to learn about the effect of whole-body vibration on hip girdle muscles in healthy children as a primary study aiming for a new clinical intervention protocol to prevent hip dislocation in patients with severe cerebral palsy.
Design: Prospective, pilot study Setting: hospital rehabilitation department Intervention: Participants will be asked to walk and jump with a surface electromyography(EMG) attached to their hip girdle muscles. After the participants are positioned(standing) on the platform of whole-body vibration device, the study practitioner will record the sEMG values from the hip girdle muscles during the vibration applied. The mean values of repeating the same process with different vibrations applications and the values before vibration will be compared by using the SPSS using the paired "t-test" or Wilcoxon signed rank test for comparison between before and after vibration in the same group.
107 studies on the registry are indexed under Hip Dislocation; 36 are open to participants now.
This study's planned enrollment of 20 is below the median of 86 across 64 interventional studies indexed under Hip Dislocation.

Exclusion Criteria:
20 healthy children aged 5 to 15 years , without any congenital or developmental abnormalities of their hip joint
Device: whole-body vibration
After attaching the surface electromyography(EMG) to bilateral hip girdle muscles, participants will walk and jump at their comfortable speed. After investigator record the muscle activation values, participants will be asked to stand on the vibration device. While the whole-body vibration is applied, the hip girdle muscles activation values will be recorded accordingly via sEMG.
muscle activation values on surface electromyography(sEMG)
surface muscle contraction of bilateral hip girdle muscles bilateral gluteus medius, tensor fascia lata, iliopsoas, rectus femoris muscles
Time frame: 10 seconds for each session
VAS (Visual Analogue Scale)
a psychometric scale that is generally used in pain scale surveys and this study participants will be asked to scale the uncomfortable feelings during the vibration
Time frame: 10 seconds for each session
Started Jun 2023 (actual). Primary completion is estimated for May 2024, 11 months after the start.
Of 32 interventional studies with no phase under Hip Dislocation, half reached primary completion within 45 months of starting (the median), counting those still running; a quarter within 18. This study's planned 11 months is below that.
