文摘

Ability to exploit redundancy was quantified using GEM analysis. GEM analysis was conducted on individuals with and without NSLBP. NSLBP group was as flexible as healthy controls in exploiting redundancy. Ability to exploit redundancy was influenced by trunk movement conditions. Conditions of trunk movement had similar effect on GEM measures of both groups.
