15 RCT's have been included. Most studies used add-on therapies. Almost all studies found improvements in both groups, but only 7 trials showed statistically significant between group differences in favor of the experimental group. Large effect sizes were found in only four studies. Conclusions: all the interventions discussed in this review can reduce the symptoms of UNS. However, TENS, optokinetic stimulation, somatosensory electrostimulation, mirror therapy and virtual reality training seem to be the most effective treatment methods (d>0,80). Future research should focus on producing studies of higher methodological quality with larger sample sizes.
