The Claim
The Bilateral Back Extensor Exosuit reduces spinal joint compression forces by 18–24% and decreases muscle activity in the upper and lower erector spinae by 15–22% during symmetric and asymmetric lifting tasks in healthy adult males.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Wearing a bilateral back extensor exosuit during lifting tasks reduces spinal joint compression forces by 18–24% and lowers muscle activity in the upper and lower back muscles by 15–22% in healthy adult males.
See the scientific wording
The Bilateral Back Extensor Exosuit reduces spinal joint compression forces by 18–24% and decreases muscle activity in the upper and lower erector spinae by 15–22% during symmetric and asymmetric lifting tasks in healthy adult males, suggesting potential for reducing acute biomechanical stress on the lumbar spine during occupational lifting.
The exosuit pulls on the pelvis and ribcage during lifting, taking some of the weight off the spine. This means the back muscles don't have to work as hard to hold the body up, so they activate less and the pressure on the spine drops.
What the research says
1 studyStudy: Bilateral Back Extensor Exosuit for multidimensional assistance and prevention of spinal injuries
A back-supporting robot suit was tested on men lifting weights, and it made their lower backs feel 15–22% less strain and reduced pressure on their spine by 18–24%. So yes, it works as claimed.
