Aim. Actually rehabilitation following orthopedic surgery aims to an even faster time for full recovery. The aim of this study was to verify whether electromagnetic fields produced by a special, registered fibre, enriched with extremely light, noble metals with conductive propriety could reduce the edema and improve the muscle trophism after surgery.
Methods. Thirty patients, attending at the same rehabilitation centre have been randomized in two groups: the first group (16) used the knee-band (Nexus-ES®) and the control group (14) used a knee-band indistinguishable for the patients and the physicians involved in the measures of the outcomes.
Results. As expected, 30 days after surgery, there is not a full equivalence in bioelectric parameters, measured by bioimpedance, between the normal limbs and the operated limbs. But while in the active group the differences are slight, in the control group the difference between the two legs are statistical significant. The difference of reactance (Xc) and phase angle (Pa) between normal and operated leg expressed as percentage is 10.7% and 7.9% respectively in the Nexus-ES® group, and 17.9% and 14.7% in the control group. No adverse events have been reported in the course of the study.
Conclusion. Data collected are preliminary but show a statistical significant difference between the groups during the rehabilitation period; patients in the active group show a faster “normalization” in the operated leg through an improvement of tissue exchanges and oxygenation.
