A reverse Phalen's maneuver involves wrist and finger extension held for 1 minute. We showed that this maneuver results in a significantly higher intracarpal canal hydrostatic pressure as compared to a traditional Phalen's or a modified Phalen's maneuver. Additionally, 31 individuals with complaints of carpal tunnel syndrome symptoms and 20 normal controls were evaluated to see what effect the reverse Phalen's maneuver would have on median sensory latency and amplitude. Both groups demonstrated a prolongation of the median sensory revoked response after 1 minute of this maneuver. The control group had a prolongation of 0.05 ms compared to 0.13 ms in the carpal tunnel syndrome group. The difference between the two groups was significant at a p = 0.05 level. This may add to the sensitivity of conventional screening methods.
反向屈腕试验是将手腕和手指伸展并保持1分钟。我们发现发现，与传统屈腕试验或改良屈腕试验相比，该试验导致腕管内静水压力显著更高。此外，对31名主诉有腕管综合征症状的个体和20名正常对照进行了评估，以观察反向屈腕试验对正中神经感觉潜伏期和波幅有何影响。两组在进行该试验1分钟后，正中神经感觉诱发电位反应均延长。对照组延长了0.05毫秒，而腕管综合征组延长了0.13毫秒。两组之间的差异在p = 0.05水平上具有显著性。这可能会提高传统筛查方法的敏感性。
