Hip Dislocation
Conditions
Brief summary
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.
Detailed description
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.
Interventions
DEVICEwhole-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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| muscle activation values on surface electromyography(sEMG) | 10 seconds for each session | surface muscle contraction of bilateral hip girdle muscles bilateral gluteus medius, tensor fascia lata, iliopsoas, rectus femoris muscles |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| VAS (Visual Analogue Scale) | 10 seconds for each session | 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 |
