Determine the reproducibility and relationship between current perception threshold testing (CPT) and quantitative sensory testing (QST) in the genital area. Sixteen women underwent CPT and QST of the vagina. CPT was done at 2,000, 250, and 5 Hz (corresponding to A-beta, A-delta, and C fibers, respectively), and QST testing was done using thermal (C fibers), vibratory (A-beta fibers), and cold (A-delta and C fibers) sensation. Ten women underwent repeated testing 1 week later. Thermal and vibratory thresholds correlated with CPT at 5 and 2,000 Hz (rho = 0.77, P = 0.002 and rho = 0.6, P = 0.01, respectively). Repeated thermal, vibratory, and cold thresholds had good concordance correlation (rho_(c) = 0.83, rho_(c) = 0.96, rho_(c) = 0.77). CPT at 5 and 2,000 Hz were also strongly correlated (rho_(c) = 69, rho_(c) = .7). CPT and QST testing stimulate similar afferent nerve fiber populations in the vagina.
确定当前感觉阈值测试（CPT）与生殖器区域定量感觉测试（QST）之间的可重复性及关系。16名女性接受了阴道的CPT和QST测试。CPT分别在2000Hz、250Hz和5Hz进行（分别对应A-β、A-δ和C纤维），QST测试使用热觉（C纤维）、振动觉（A-β纤维）和冷觉（A-δ和C纤维）。10名女性在1周后接受了重复测试。热觉和振动觉阈值与5Hz和2000Hz的CPT相关（rho分别为0.77，P = 0.002和rho = 0.6，P = 0.01）。重复的热觉、振动觉和冷觉阈值具有良好的一致性相关性（rho_c = 0.83，rho_c = 0.96，rho_c = 0.77）。5Hz和2000Hz的CPT也具有强相关性（rho_c = 0.69，rho_c = 0.7）。CPT和QST测试刺激阴道中相似的传入神经纤维群体。
