An interventional study of Whole-body vibration (WBV) in Body Weight, Vibration and Motor Activity, sponsored by Universidad Rey Juan Carlos. Completed at 1 site in Spain. Open to participants aged 18 Years to 30 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2017-11-28.
Sponsored by Universidad Rey Juan Carlos · Not applicable, Interventional, and Treatment
Purpose: To evaluate the short-term effects of whole-body vibration (WBV), using reciprocating plate technique, on manual ability performance in healthy younger.
Material and methods: 38 healthy young volunteers were randomized to WBV group (N=19; 6 men, 13 women; mean age 21, 3.8yrs) or control group (N=19; 6 men, 13 women; mean age 20.5, 3.5yrs). The subjects in the WBV group performed one series of five consecutive repetitions of 60 sec unsynchronised WBV (Zeptoring, Scisen GmbH, Germany; 4 Hz, amplitude 3mm) with a 1-min pause between administrations, three times a week. The controls did not receive any training. Both groups were evaluated at baseline and after intervention, in the Rey Juan Carlos University´s Gait Analysis Laboratory. Four outcome measures of Purdue Pegboard test (PPT): preferred hand (PH), non-preferred hand (NPH), both hands (BH) and assembly (A) was performed baseline and 5 min after intervention.
Exclusion criteria:
The subjects in the WBV group performed one series of five consecutive repetitions of 60 sec unsynchronised multidimensional WBV (Zeptoring, Scisen GmbH, Germany; 4 Hz, amplitude 3mm) with a 1-min pause between administrations, three times a week. The construction of this device is designed to perform a nonharmonious generation of oscillating movements in vertical and horizontal planes in order to prevent occurrences of resonance and habituation of receptors. During the intervention, subjects wore thin-soled gymnastic-type shoes, carrying out in a squatting standing position, with slight flexion at the hips, knees and ankle joint, on the vibration platform.
Device: Whole-body vibration (WBV)
The controls did not receive any training.
Whole-body vibration (WBV) is a novel neuromuscular therapeutic intervention that has recently been developed since in the mid-1960s. Hagbart and Eklund showed in human experiments that a reflex muscle contraction can result as a consequence of applying vibrations to the muscular-tendon system. The subjects stand on a platform that generates stochastic vibrations at a frequency between 1-12.5 Hz.
Purdue Pegboard test (change)
Change in Purdue Pegboard test. This tool evaluates the fine dexterity
Time frame: Baseline, immediately after intervention and one month after the intervention
Plan to share: Undecided
