This study investigates the results of a questionnaire, provocative tests, and ultrasonographic measurements of carpal tunnel morphological parameters in intensive and nonintensive electronic device users.
Forty-eight university students (equal numbers of intensive and nonintensive users, ≥5 h/day and <5 h/day of electronic device usage, respectively) were randomly selected after questionnaire responses were received and evaluated clinically and by ultrasonography. All participants were right-handed.
Intensive users had significantly more positive results in Phalen's and Durkan's tests and reported more wrist/hand pain compared with nonintensive users (P < 0.05). Intensive users also had significantly larger median nerve cross-sectional areas, flattening ratios, and perimeters as well as greater bowing of the transverse carpal ligament compared with nonintensive users (P < 0.05).
Overuse of electronic devices may adversely affect the median nerve within the carpal tunnel and the transverse carpal ligament, resulting in numbness, tingling, and pain in the hand. Caution may be warranted when using handheld electronic devices. Muscle Nerve 56: 873-880, 2017.
本研究调查了密集型和非密集型电子设备使用者的问卷调查结果、激发试验以及腕管形态学参数的超声测量结果。
在收到问卷调查回复后，随机选取48名大学生（密集型和非密集型使用者人数相等，每天使用电子设备分别≥5小时和<5小时），并对其进行临床评估和超声检查。所有参与者均为右利手。
与非密集型使用者相比，密集型使用者在Phalen试验和Durkan试验中阳性结果显著更多，且报告的手腕/手部疼痛更多（P < 0.05）。与非密集型使用者相比，密集型使用者的正中神经横截面积、扁平率和周长也显著更大，腕横韧带的弯曲度也更大（P < 0.05）。
过度使用电子设备可能会对腕管内的正中神经和腕横韧带产生不利影响，导致手部麻木、刺痛和疼痛。使用手持电子设备时可能需要谨慎。《肌肉与神经》56: 873 - 880, 2017年。
