Background: The aim of the present preliminary randomized controlled study was to ascertain whether the use of newly developed nanotechnologies-based patches can influence posture control of healthy subjects.METHODS: Thirty healthy female subjects (age 39.4 years, BMI 22.74 kg/m2) were randomly assigned to two groups: one with active patchesand a control group with sham patches. Two patches were applied with a tape: one on the subject's sternum and the other on the C7 apophysis.Body sway during quiet upright stance was recorded with a dynamometric platform. Each subject was tested under two visual conditions, eyesopen and closed. We used a blocked stratifed randomization procedure conducted by a third party.RESULTS: Subjects wearing the sham patches showed a signifcant increase of the center of pressure sway area after 4 hours when they performed the habitual moderate-intensity work activities. In the active patch group, a decrease of the sway path was evident, providing evidenceof an enhanced balance control.CONCLUSIONS: Our preliminary fndings on healthy subjects indicate that nanotechnological devices generating ultra-low electromagneticfelds can improve posture control.
