EA intervention improved gait impairments of gout arthritis model mice. A Schedule for model establishment, gait analysis and EA/sham EA treatment. B Representative pictures illustrating the mice from each group recorded by the gait analysis system at 0 (baseline), 8 or 24 h time points after model establishment. The left panel shows the instant images of the mice on the treadmill. The right panel shows the paw area being analyzed. The letter L or R denote left or right, whereas F or H denote forepaw or hind paw, respectively. C–E Summary of paw area ratio (RH/LH), stride length ratio (RH/LH) and swing ratio (RH/LH) of baseline (− 24 h), 8 h and 24 h time points. n = 7–8 mice/group. *p < 0.05, **p < 0.01. NS no significance
