Three provocative tests (pressure, Phalen's test, and Tinel's sign) were studied in 30 patients with carpal tunnel syndrome and 30 control subjects. The pressure provocative test had a sensitivity of 100%. In contrast, Phalen's test was 88% sensitive and Tinel's sign only 67% sensitive. The pressure provocative test is a sensitive indicator of median nerve compression at the wrist with a faster reaction time than Phalen's test (mean time of 9 seconds vs 30 seconds). It is an appropriate provocative test in patients with stiff or painful wrists when wrist flexion is restricted.
对30例腕管综合征患者和30名对照者进行了三项激发试验（压力试验、Phalen试验和Tinel征）。压力激发试验的敏感性为100%。相比之下，Phalen试验的敏感性为88%，Tinel征仅为67%。压力激发试验是腕部正中神经受压的敏感指标，其反应时间比Phalen试验更快（平均时间为9秒对30秒）。对于手腕僵硬或疼痛、手腕屈曲受限的患者，它是一种合适的激发试验。
