Postures and work-hobby activities may play a role in the origin and progression of ulnar neuropathy at the elbow (UNE), whose occurrence appears to be increasing. The time spent on mobile-phone has increased in the last decades leading to an increased time spent with flexed elbow (prolonged-phone-posture, PPP). We aimed to assess the effect of PPP both in patients with symptoms of UNE and in symptom-free subjects.
Patients with pure sensory symptoms of UNE and negative neurophysiological tests (MIN-UNE) and symptom-free subjects were enrolled. We evaluated ulnar motor nerve conduction velocity across elbow at baseline and after 6, 9, 12, 15, and 18min of PPP in both groups. Fifty-six symptom-free subjects and fifty-eight patients were enrolled. Globally 186 ulnar nerves from 114 subjects were studied.
Conduction velocity of ulnar nerve across the elbow significantly changed over PPP time in patients with MIN-UNE, showing a different evolution between the two groups.
PPP causes a modification of ulnar nerve functionality in patients with MIN-UNE.
PPP may cause transient stress of ulnar nerve at elbow.
姿势和工作-爱好活动可能在肘管综合征（UNE）的发病及进展中起作用，而UNE的发病率似乎正在上升。在过去几十年中，人们使用手机的时间增加，导致屈肘时间增多（长时间持手机姿势，PPP）。我们旨在评估PPP对有UNE症状患者和无症状受试者的影响。
纳入有单纯UNE感觉症状且神经生理学检查阴性的患者（轻度UNE，MIN-UNE）以及无症状受试者。我们在两组受试者基线时以及PPP持续6、9、12、15和18分钟后，评估其肘部尺神经运动神经传导速度。共纳入56名无症状受试者和58名患者。总计对来自114名受试者的186条尺神经进行了研究。
在MIN-UNE患者中，肘部尺神经的传导速度随PPP时间显著变化，两组间呈现出不同的变化趋势。
PPP会导致MIN-UNE患者尺神经功能改变。
PPP可能会导致肘部尺神经的短暂受压。
