Myoelectricity and deep resistance at acupoints following acupuncture before and after de qi. The Viking Quest portable EMG/evoked potential systems were used in this study for analysis of the myoelectricity and deep resistance. The deep resistance before de qi in Hegu acupoint of the healthy subjects was 34.85 ± 12.43, which was increased to 51.98 ± 11.84 uV after de qi (P < 0.01). The similar results were seen for Zusanli acupoint which was 39.38 ± 9.07 uV before de qi and 55.18 ± 6.19 uV after de qi (P < 0.01). Figure 5 is the representative image of myoelectricity at acupoints following acupuncture before and after de qi ((a1) and (a2) for Hegu; (b1) and (b2) for Zusanli). The amplitudes of myoelectricity after de qi in Hegu and Zusanli were significantly increased than those before de qi.
