Patients with head injuries frequently complain of a decreased ability to endure intense light and sound stimuli. The few psychophysical studies that have objectively studied this type of hyperaesthesia have not assessed to what extent patients recover from this hyperaesthesia after mild head injury (MHI). A computerised rating technique was used to assess tolerance to intense sound (95 dB) and light (1500 lux) stimuli in patients with an uncomplicated MHI. Patients were tested 10 days and five weeks after the injury. Although most patients substantially recovered from both visual and acoustic hyperaesthesia, 25% of the patients were still not able to endure intense stimuli by five weeks. Analysis of data obtained with two behavioural rating scales (one with post-concussive/cognitive complaints and a second with emotional/vegetative complaints) indicated that visual hyperaesthesia was specifically related to the post-concussive/cognitive complaints scale.
头部受伤的患者经常抱怨忍受强光和声音刺激的能力下降。少数客观研究这类感觉过敏的心理物理学研究并未评估轻度头部损伤（MHI）后患者从这种感觉过敏中恢复的程度。采用计算机评分技术评估单纯性MHI患者对高强度声音（95分贝）和光线（1500勒克斯）刺激的耐受性。在受伤后10天和5周对患者进行测试。尽管大多数患者的视觉和听觉感觉过敏基本恢复，但25%的患者在5周后仍无法忍受强烈刺激。对两个行为评分量表（一个用于评估脑震荡后/认知方面的症状，另一个用于评估情绪/植物神经方面的症状）所获得的数据进行分析表明，视觉感觉过敏与脑震荡后/认知方面的症状量表特别相关。
