The Claim
The Bilateral Back Extensor Exosuit reduces muscle activity in the upper and lower erector spinae by 15–22% during both 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.
A wearable exosuit designed for the back reduces muscle activity in the lower and upper back muscles by 15–22% when healthy adult males lift objects in symmetric and asymmetric ways.
See the scientific wording
The Bilateral Back Extensor Exosuit reduces muscle activity in the upper and lower erector spinae by 15–22% during both symmetric and asymmetric lifting tasks in healthy adult males, indicating potential for decreasing acute muscular fatigue during repetitive lifting.
The exosuit takes some of the weight off the spine, so the back muscles don't need to contract as hard to keep the spine stable during lifting.
What the research says
1 studyStudy: Bilateral Back Extensor Exosuit for multidimensional assistance and prevention of spinal injuries
The study found that when men wore this back suit while lifting, their lower back muscles worked 15–22% less — just like the claim says. This means the suit helps the muscles not have to strain as much.
