The active TENS group had an improved perception of change and a greater number of responders with regard to the degree of change in movement‐evoked pain or fatigue during a 6MWT compared to the placebo TENS or no TENS groups. A, The percentage of participants who reported feeling better or much better (blue), no change (green), and worse or extremely worse (red) after 4 weeks of active TENS, placebo TENS, or no TENS treatment. The majority of individuals reported a significant overall improvement after using active TENS compared to those who used placebo TENS or no TENS (P < 0.0001). There were no differences between the placebo TENS and no TENS groups (P = 0.175). B, Percentages (with 95% confidence intervals [95% CIs]) of subjects in each treatment group who had a clinically meaningful response to TENS (as described by Arnold and colleagues 43, i.e., ≥30% reduction [pain], ≥20% reduction [fatigue, function]). There was a significantly greater number of responders for pain, fatigue, and both pain and fatigue in the active TENS group compared to the placebo TENS and no TENS groups. Function was measured according to the Revised Fibromyalgia Impact Questionnaire 39. See Figure 2 for other definitions.
