The effect of Magnetic and Hologram bracelets on balance.

摘要

PURPOSE: The purpose of this study was to examine the effects of Magnetic and Hologram bracelets on balance. METHODS: This research is a quasi-experimental, within subjects, repeated measures design. The independent variable will be bracelet condition. This condition will have four levels, Hologram bracelet, Magnetic bracelet, Placebo bracelet, and no bracelet. The dependent variable will be balance score based on the force platform and AMTINetForce software application, which will be used to run the force platform. Calibration, platform zeroing and the testing trials were run through this software. It allowed correction for body weight, start and stop each trial, and rerun trials if necessary. The Biosoft software program was also used in conjunction with the force platform and AMTINetForce. After running each trial through AMTINetForce, data was reconfigured and accessed through Biosoft. Biosoft provided raw data, graphical analysis and charted comparison between trials. FINDINGS: Twenty-three active, able volunteers, male and female, from California University of Pennsylvania volunteered to participate in the following study. The volunteers were made up of 9 males, and 14 females. All 23 subjects completed the testing successfully, with no reported injuries. The age rang for the participants were from 18 years of age, up to 26 years of age. Four subjects collected data was disqualified from further examination due to error that occurred during the data collection process. The disqualification of their collected data was decided due to lack of evidence to support the four bracelet conditions. Therefore, only 18 subjects qualified to have their data analyzed further. A one-way repeated-measures analysis of variance (ANOVA) was performed comparing the effect of the independent variables, Power Balance bracelet, magnetic bracelet, placebo bracelet, and no bracelet on the dependent variable, each balance score based on the force platform. No significant difference was found (f(3,51)=0.434, p>.05). No significant difference exists among bracelet conditions, Power Balance bracelet (m=0.566, sd=0.2014), Magnetic-Copper bracelet (m=0.622, sd=0.3031), placebo bracelet (m=0.608, sd=0.1996), and no bracelet (m=0.617, sd=0.2093) means. CONCLUSION: The recording of these findings report that magnetic and holograms bracelets have no significant effect on balance, resulting in no negative or positive benefits of the application of these bracelets.
