Fig. 3From: Muscle synergy patterns as altered coordination strategies in individuals with chronic low back pain: a cross-sectional studyIndividual (thin line) and mean participant (think lines) percentages of the variability accounted for (VAF). The left and right panels indicate the VAFs of the non-CLBP and CLBP groups, respectively. The horizontal dashed lines indicate the thresholds used to determine the number of extracted trunk muscle synergiesBack to article page
