Sports acupuncturist Lijana Shestopal says the device could work for some postures, but it won’t work for all.
“If somebody has rounded shoulders, it is a great device to use on the upper back so the upper thoracic area gets a stretch. For the lower back it is only good for those people that have a posterior tilt (the posture that would look as if a person is tucking in their glutes),” she tells SheKnows. “However, for someone with anterior tilt (increased lordosis of the lumbar area), this device would create more issues such as low back pain and facet joint pain (the pain one may get about 1 inch away from the spine).”
