The Effect of a Silicone Wristband in Dynamic Balance

Abstract

The effect of a wristband on the dynamic balance of young adults was assessed. Twenty healthy young adults wore a commercial Power BalanceT or fake silicone wristband. A 3D accelerometer was attached to their lumbar region to measure body sway. They played the video game Tightrope (Wii video game console) with and without a wristband; body sway acceleration was measured. Mean balance sway acceleration and its variability were the same in all conditions, so silicone wristbands do not modify dynamic balance control.

The effect of holographic wristbands on body balance. [El efecto de las pulseras holográficas en el equilibrio corporal].

“…Wearing a holographic wristband had no effect on any of the sensorial (visual, vestibular, somatosensorial) variables measured, as shown previously (Marban, Vega, Rodríguez, Pérez, & Ramos, 2011;Brice, Jarosz, Ames, 2011;Pothier, 2012;Teruya, Matareli, Romano, 2013). The present sensorial results were similar to those reported by Wrisley (Wrisley, Stephens, Mosley, Wojnowski, Duffy, & Burkard, 2007), whose study involved a similar sample of subjects (somatosensorial 0.97±0.01 compared to 0.97±0.04, visual 0.95±0.02 compared to 0.95±0.02, vestibular 0.77±0.08 compared to 084±0.03), confirming the present subjects to have good postural control.…”

“…http://dx.doi.org/10.5232/ricyde2014.03802 307 is mainly used in three-dimensional imaging systems for the recording of information (Metha, 2005;Shiota, 2008), or in the production of biosensors that indicate via chromatic changes the concentration of metabolites such as lactate (Sartain, Yang, & Lowe, 2006) or glucose (Kabilan, Marshall, Sartain, Lee, Hussain, & Yang, 2005), or the pH (Marshall, Blyth, Davidson, & Lowe, 2003). To our knowledge, we could only find four studies that was performed to determine de effectiveness or the holographic balance band with regard to improved balance, flexbility, and strength (Verdan, Marzilli, Barna, Roquemore, Fenter, Blujus, & Gosselin, 2012;Teruya, Matareli, & Romano, 2013;Brice, Jarosz, Ames, Baglin, & Da Costa, 2011;Pothier, Thiel, Khoo, Dillon, & Rutka, 2012).…”

“…Despite its popularity and many endorsements by profesional athletes, holographic wristbands have not demonstrated and effect on improving dynamic (Teruya, Matareli, & Romano, 2013) or static balance control (Verdan, Marzilli, Barna, Roquemore, Fenter, Blujus, & Gosselin, 2012;Pothier, Thiel, Khoo, Dillon, & Rutka, 2012). The specific test was used as a determinant of balance was the modified Test of Sensory Interaction on Balance (m-CTSIB).…”

Uso do acelerômetro e giroscópio no monitoramento de movimento: uma avaliação comparativa por meio de unidade inercial e smartphone

“…Além do nível de atividade física, outras variáveis como postura e equilíbrio 15 têm sido avaliadas por intermédio desses instrumentos. O acelerômetro pode ser aplicado para diversos estudos, incluindo balanço postural, déficits de atividade da vida diária, contagens de atividade física que inferem ao sedentarismo.…”
