An investigation of the effects of holographic wristbands on strength, balance and flexibility - A double-blind placebo controlled study

Abstract

[Purpose] This study investigated the effects of holographic wristbands on strength, balance and flexibility. [Subjects and Methods] The study included 43 healthy university students, 15 females (34.88%) and 28 males (65.12%), attending the Department of Physiotherapy and Rehabilitation at Marmara University. The age of the participants ranged from 19 to 27 (mean age 21.2 ± 1.7 years). Strength, balance with eyes open, balance with eyes closed and flexibility were evaluated under four different conditions of wearing holographic EFX®, PWX® and placebo wristbands, and no wristband. [Results] In evaluations of strength, balance with eyes are open, balance with eyes closed and flexibility, a significant difference was observed in favor of the placebo wristband compared to the PWX® wristband. For the other tests, holographic wristbands had no effect on strength, flexibility or balance with eyes closed. [Conclusion] It was concluded that holographic wristbands, which are marketed asergogenic aids, have no effect on strength, balance or flexibility.
