血流量减少可能导致上肢肌肉骨骼疾病（UEMSD）的病理生理学，如肌腱炎和腕管综合征。本研究的目的是表征皮肤温度的潜在差异，在3组办公室工作人员中，在9分钟打字挑战后通过动态热成像法进行评估：UEMSD患者，有（n=6）或没有（n=10）因键盘使用而加剧的手冷，对照组（n=12）。在分型前1 min和分型后3个2 min采样期间[0-2 min（早期）、3-5 min（中期）和8-10 min（晚期）]获得手背掌骨区域的温度图像。打字后，平均体温立即从基线水平升高，幅度相似，对照组为0.7（0.3）摄氏度，UEMSD病例中没有手冷的为0.6（0.2）摄氏度，但手冷的仅为0.1（0.3）摄氏度。使用配对t检验组内比较连续成像期间的平均背温，三种模式的温度变化是明显的，在10分钟后分型。对照组在分型后3-5分钟平均体温进一步升高0.1 ℃（t检验，P=0.001），随后体温下降-0.3 ℃（t检验，P=0.04），而无手冷的病例在中期或晚期与最初的分型后平均体温升高没有变化。相比之下，受试者与键盘引起的冷手没有变化，从最初的打字后的温度，直到在后期下降-0.3 ℃（t检验，P=0.06）。红外热成像似乎区分三组受试者，键盘引起的手冷症状可能是由于，至少部分是由于血流减少。
Reduced blood flow may contribute to the pathophysiology of upper extremity musculoskeletal disorders (UEMSD), such as tendinitis and carpal tunnel syndrome. The study objective was to characterize potential differences in cutaneous temperature, among three groups of office workers assessed by dynamic thermography following a 9-min typing challenge: those with UEMSD, with (n=6) or without (n=10) cold hands exacerbated by keyboard use, and control subjects (n=12). Temperature images of the metacarpal region of the dorsal hand were obtained 1 min before typing, and during three 2-min sample periods [0-2 min (early), 3-5 min (middle), and 8-10 min (late)] after typing. Mean temperature increased from baseline levels immediately after typing by a similar magnitude, 0.7 (0.3)degreesC in controls and 0.6 (0.2)degreesC in UEMSD cases without cold hands, but only by 0.1 (0.3)degreesC in those with cold hands. Using paired t-tests for within group comparisons of mean dorsal temperature between successive imaging periods, three patterns of temperature change were apparent during 10 min following typing. Controls further increased mean temperature by 0.1degreesC (t-test, P=0.001) at 3-5 min post-typing before a late temperature decline of -0.3degreesC (t-test, P=0.04), while cases without cold hands showed no change from initial post-typing mean temperature rise during middle or late periods. In contrast, subjects with keyboard-induced cold hands had no change from initial post-typing temperature until a decrease at the late period of -0.3degreesC (t-test, P=0.06). Infrared thermography appears to distinguish between the three groups of subjects, with keyboard-induced cold hand symptoms presumably due, at least partially, to reduced blood flow.
