BACKGROUND
We assessed lateral preference in 80 male patients with combat-related post-traumatic stress disorder (PTSD) and in 100 healthy age-matched male controls.
METHODS
Hand, foot, eye and ear preferences were examined, using the Edinburgh Handedness Inventory-Modified and the Coren Inventory of Lateral Preference.
RESULTS
Mixed lateral preference was noted in significantly more PTSD patients than controls (65 v. 43%, P < 0.005).
CONCLUSIONS
These results indicate a possible hemispheric imbalance (less lateralization) in PTSD patients, with the right hemisphere playing a more active role in perceptual and cognitive processing and in the regulation of biological responses in these patients. This imbalance may be relevant to the pathophysiology of PTSD.
背景
我们评估了80名患有与战斗相关创伤后应激障碍（PTSD）的男性患者以及100名年龄匹配的健康男性对照的侧偏好。
方法
使用爱丁堡利手量表修订版和科伦侧偏好量表检查手、脚、眼和耳的偏好。
结果
与对照组相比，PTSD患者中观察到混合侧偏好的比例显著更高（65%对43%，P<0.005）。
结论
这些结果表明PTSD患者可能存在半球失衡（侧化程度较低），右半球在这些患者的感知和认知加工以及生物反应调节中发挥更积极的作用。这种失衡可能与PTSD的病理生理学相关。
