This study by researchers at U.C. Berkeley and U.C. San Francisco showed an average 60% reduction in EMG muscle activities at four of the most injury-prone lower back muscle groups.
Electrodes were placed over four erector spinae muscle groups on each of eight test subjects who were tested both while wearing and not wearing the backX.
The chart shows the substantial decrease in four muscle groups’ activation while subjects were wearing the BackX.
TSE, in this figure, stands for Trunk Support Exoskeleton; an original technical name for BackX.
