压痛阈测量在深部痛的疗效评价

Study of Pressure-pain Threshold on Deep-Seated Pain

对１２０例各种疼痛患者进行痛阈测量，结果患处痛阈均值为０．５６±０．３２ｍＡ，健侧为０．６０±０．４４ｍＡ；对７５例进行皮温测量的结果是患处皮温均值为３３．５３±１．１５℃，健侧为３３．６２±１．２８℃，两项的两组间差异均无显著性．对８８例进行压痛阈测量，发现患处的压痛阈值全部低于健侧，患地压痛阈均值为１．５８±０．７５ｋｇ／ｃｍ２，健侧为２．９１±０．９９ｋｇ／ｃｍ２，两组差异有非常显著性．当疼痛减轻后所有患处的压痛阈值均升高，前后比较差异有非常显著性．压痛阈测量比皮温和痛阈测量能更好地反映深部痛的状况及疼痛的轻重变化，是当前对深部病疗效评价的一个比较好的方法，可以作为常规检查项目之一．

The 120 patients with various pains were studied in measurement of pressure-pain threshold on the deep-seated pain in this paper. The result showed that the mean of the skin temperature on the pain areas in 75 out of 120 cases was 33. 53±1.15℃, on the opposite side of these patients(healthy areas)it was 33.62 ±1.28℃. There was no difference. With the measurement of pressure-pain threshold, the mean value of pressure-pain threshold on the pain areas in 88/120 cases was 1. 58±0.75kg/cm2 and that of the opposite healthy areas was 2.91±0.99kg/cm2. There was a significant difference. It was found that the value of pressre-pain threshold on the pain areas was lower than that of the healthy areas. When the pain is alleviated, the value of pressure-pain threshold rises too. It is suggested that the measurement of pressure-pain threshold is a useful method for evaluating the effect of deep-seated pain.
