From: Lidocaine patch (5%) is no more potent than placebo in treating chronic back pain when tested in a randomised double blind placebo controlled brain imaging study

Figure 1

Pain did not differ between chronic back pain (CBP) patients treated with 5% lidocaine patches or with patches containing no active drug (placebo). A. Variation of CBP pain with treatment type and treatment duration. Treatment duration, but not type, significantly decreased CBP pain. B-E. Effect of treatment type and duration on sensory (range 0-33) and affective scores (range 0-12) obtained on the McGill pain Questionnaire (MPQ). Sensory and affective scores decreased with treatment duration for both types of treatment. Error bars represent SEMs. * p ≪ 0.05, ** p ≪ 0.01 differences from baseline.
