Myoelectric activity and range of motion during ULNT1 were recorded in 62 breast cancer (BC) survivors who had axillary lymph node dissection (n = 30) or sentinel lymph node biopsy (n = 32) within the previous 18 months, and 63 age-matched healthy women. BC survivors' symptoms were reproduced by ULNT1 and exhibited greater myoelectric activity in the biceps brachii than healthy women (MD (95% CI): 21,26 (10,83-31,70)). No differences between the axillary lymph node dissection and sentinel lymph node biopsy groups (MD (95% CI): 8,47 (-7,84-24,79)) were found. Myoelectric activity in the triceps brachii was greater in the sentinel lymph node biopsy group (MD (95% CI): 2,70 (-2,06-7,60)). BC survivors exhibited less shoulder and elbow range of motion during ULNT1 than healthy women. Increased upper limb nerve mechanosensitivity in BC survivors was associated with a greater protective muscle response during ULNT1.
在62例乳腺癌（BC）幸存者和63例年龄匹配的健康女性中记录了上肢神经张力测试1（ULNT1）期间的肌电活动和运动范围。这些乳腺癌幸存者在过去18个月内接受了腋窝淋巴结清扫术（n = 30）或前哨淋巴结活检（n = 32）。ULNT1再现了乳腺癌幸存者的症状，并且与健康女性相比，肱二头肌的肌电活动更大（平均差（95%置信区间）：21.26（10.83 - 31.70））。未发现腋窝淋巴结清扫组和前哨淋巴结活检组之间存在差异（平均差（95%置信区间）：8.47（-7.84 - 24.79））。前哨淋巴结活检组肱三头肌的肌电活动更大（平均差（95%置信区间）：2.70（-2.06 - 7.60））。与健康女性相比，乳腺癌幸存者在ULNT1期间的肩部和肘部运动范围更小。乳腺癌幸存者上肢神经机械敏感性增加与ULNT1期间更大的保护性肌肉反应相关。
