The effect of close proximity holographic wristbands on human balance and limits of stability: A randomised, placebo-controlled trial

An Investigation of the Effects of Holographic Wristbands on Strength, Balance and Flexibility- a Double-Blind Placebo Controlled Study

“…There is increased use each year of holographic wristbands as an ergogenic aid among the general population 6) . However, a review of the literature found no evidence-based study demonstrating improved performance through the use of holographic wristbands.…”

“…However, a review of the literature found no evidence-based study demonstrating improved performance through the use of holographic wristbands. Brice et al analyzed the effects of holographic wristbands on balance and stability performance using a posturography method and reported that placebo and holographic wristbands elicited no changes in balance 6) . Similarly, our study found that EFX® and PWX® wristbands had no effect on balance with eyes closed.…”

“…Similarly, our study found that EFX® and PWX® wristbands had no effect on balance with eyes closed. Unlike the study of Brice et al 6) , we evaluated balance using a myometer rather than posturography. Since the manufacturers of EFX® and PWX® wristbands claim that these wristband have positive effects on balance, strength and flexibility 8,9) , we also investigated the effects of placebo and other wristbands on flexibility and grip strength in addition to balance.…”

“…While some of these aids have been shown to effect performance when used in specific situations, others remain controversial 5) . It has been suggested that the placebo effect plays a major role in the benefits claimed for some ergogenic aids 6) . McClung et al 7) also reported that the placebo effect contributed significantly to performance.…”

“…Products incorporating hologram technology have recently been widely marketed as ergogenic products 6) . Holographic wristbands from various manufacturers are widely available [8][9][10][11] .…”
