A follow-up study was conducted in forty-one men (fifty-five hands) treated surgically for carpal tunnel syndrome. The number of hours of vibration exposure and exactly which hand tool was used were recorded and each tool was categorized according to vibration level. The patients were divided into a low exposure and a high exposure group. Age at surgery, mean distal latency in the median nerve, and the duration between onset of symptoms and surgery were similar for the two groups. Only one patient experienced nocturnal paresthesia at follow-up in the low exposure group in contrast to twelve in the high exposure group. This corresponded to an age-standardized odds ratio (relative risk) of eighteen for nocturnal paresthesia after surgery in the high exposure group, with the low exposure group as referents. Previous vibration exposure may influence the recovery after carpal tunnel surgery.
对41名接受腕管综合征手术治疗的男性（55只手）进行了一项随访研究。记录了振动暴露的小时数以及具体使用的手动工具，并根据振动水平对每种工具进行了分类。患者被分为低暴露组和高暴露组。两组患者的手术年龄、正中神经的平均远端潜伏期以及症状出现至手术的持续时间相似。低暴露组在随访时只有1名患者出现夜间感觉异常，而高暴露组有12名。以低暴露组为参照，这相当于高暴露组术后夜间感觉异常的年龄标准化比值比（相对风险）为18。既往的振动暴露可能会影响腕管手术后的恢复。
