Does Electroacupuncture Treatment Reduce Pain and Change Quantitative Sensory Testing Responses in Patients with Chronic Nonspecific Low Back Pain? A Randomized Controlled Clinical Trial

Table 2

Pain intensity and quantitative sensory testing in patients with chronic nonspecific low back pain before and after treatment. NWC: number of words chosen. PRI: pain rating index. TDT: tactile detection threshold. TAM: tibialis anterior muscle. PPT: pressure pain threshold. CTR: control group. Data expressed as mean and standard error of the mean. p<0.05. p<0.01. Wilcoxon matched pairs test.
