The present study aimed to examine the perception of music and prosody in patients who had undergone a severe traumatic brain injury (TBI). Our second objective was to describe the association between music and prosody impairments in clinical individual presentations. Thirty-six patients who were out of the acute phase underwent a set of music and prosody tests: two subtests of the Montreal Battery for Evaluation of Amusia evaluating respectively melody (scale) and rhythm perception, two subtests of the Montreal Evaluation of Communication on prosody understanding in sentences, and two other tests evaluating prosody understanding in vowels. Forty-two percent of the patients were impaired in the melodic test, 51% were impaired in the rhythmic test, and 71% were impaired in at least one of the four prosody tests. The amusic patients performed significantly worse than non-amusics on the four prosody tests. This descriptive study shows for the first time the high prevalence of music deficits after severe TBI. It also suggests associations between prosody and music impairments, as well as between linguistic and emotional prosody impairments. Causes of these impairments remain to be explored.

严重创伤性脑损伤后音乐和言语韵律的感知

本研究旨在检查遭受严重创伤性脑损伤 (TBI) 的患者对音乐和韵律的感知。我们的第二个目标是描述临床个体表现中音乐和韵律障碍之间的关联。36 名超出急性期的患者接受了一组音乐和韵律测试：蒙特利尔 Battery for Evaluation of Amusia 的两个子测试分别评估旋律（音阶）和节奏感知，蒙特利尔评估交流的两个子测试关于韵律对句子的理解，以及另外两个评估元音韵律理解的测试。42% 的患者在旋律测试中受损，51% 在节奏测试中受损，71% 在四项韵律测试中的至少一项中受损。在四项韵律测试中，音乐患者的表现明显低于非音乐患者。这项描述性研究首次显示了严重 TBI 后音乐缺陷的高患病率。它还表明韵律和音乐障碍之间以及语言和情感韵律障碍之间的关联。这些损伤的原因仍有待探索。
