Skorupska E, Zawadziński J, Bednarek A, Samborski W - Biomed Res Int (2015)

Bottom Line: The SkR decrease of TrPs-positive sites as compared to TrPs-negative sites and the surrounding tissue was confirmed.However, no statistically significant difference in the SkR value occurred when all data were analyzed.SkR reactive changes at latent TrPs are possible but the results were not consistent with the previous study.

ABSTRACT

Introduction: The skin resistivity (SkR) measurement is commonly recommended for acupoints measurement, but for trigger points (TrPs) only one study is available. The purpose of the study was to evaluate SkR for latent TrPs compared to non-TrPs and the surrounding tissue.

Material and methods: Forty-two healthy volunteers with unilateral latent upper trapezius TrPs (12 men, 30 women) aged 21-23 (mean age: 22.1 ± 0.6 y) participated in the study. Keithley electrometer 610B was used for measuring SkR (Ag/AgCl self-adhesive, disposable ground electrode: 30 mm diameter). SkR was measured for latent TrPs and compared to opposite non-TrPs sites and the surrounding tissue.

Results: The SkR decrease of TrPs-positive sites as compared to TrPs-negative sites and the surrounding tissue was confirmed. However, no statistically significant difference in the SkR value occurred when all data were analyzed. The same was confirmed after gender division and for TrPs-positive subjects examined for referred pain and twitch response presence.

Conclusion: SkR reactive changes at latent TrPs are possible but the results were not consistent with the previous study. Thus, caution in applying SkR to latent TrPs isolation is recommended and its clinical use should not be encouraged yet. Further studies, especially on active TrPs, are yet required.

Mentions: After sex division, a contrary tendency of skin resistivity value was observed: among women, SkR decrease of TrPs sites compared to the surrounding tissue (norm), and for men, SkR increase for TrPs compared to norm (Figure 3). For both subgroups, the two-tailed t-tests confirmed no significant changes in skin resistivity between TrPs-positive to the surrounding tissue (norm) (women p = 0.07; men p = 0.56) and TrPs-negative (control) (women p = 0.23; men p = 0.34) after sex division. After rejecting markedly different values, the same tendency was confirmed.
