Combined abnormal muscle activity and pain-related factors affect disability in patients with chronic low back pain: An association rule analysis

In patients with chronic low back pain (CLBP), reduced lumbar flexion-relaxation and reduced variability of muscle activity distribution are reported as abnormal muscle activity. It is not known how abnormal muscle activity and pain-related factors are related to CLBP-based disability. Here, we performed an association rule analysis to investigated how CLBP disability, muscle activity, and pain-related factors in CLBP patients are related. <br>This data set is all variables values and categorized "Low" or "High" for association rules analysis.
