Abstract：
Equine headshaking syndrome is a poorly understood neuropathic pain condition presenting as uncontrollable shaking, flicking, or striking of the head. Therapeutic options are limited, and treatments are only partially successful. Currently, epidemiological information on headshaking in the Southern Hemisphere is lacking. An online survey was circulated to Australian owners of headshaking horses to collect information on triggers, symptoms, seasonality, treatments, and perceived treatment efficacy. The responses (n = 216) showed the mean age at symptom onset as 9.6 (±4.7) years. More geldings were affected than mares (76% vs. 24%), and symptom onset occurred later in geldings compared to mares (10.1 ± 4.7 vs. 7.9 ± 4.0 years; p < 0.01). Bright sunlight, wind, and high pollen were the most commonly reported triggers (61%, 46% and 40%, respectively), and seasonal onset of symptoms was reported by 54% of respondents. In total, 71% of respondents reported using two or more treatments. The most common treatments were supplements (68%), nose nets (63%), light-blocking masks (48%), bodywork (48%) and pharmaceutical compounds (38%). Overall, treatments were considered ineffective by 33% of respondents. The findings were in agreement with surveys from the Northern Hemisphere. Of note was the perception of bright light as a primary trigger, alongside the reported low treatment efficacy of light-blocking masks. Seasonal intensification of symptoms and its relationship to day length merits further exploration.
摘要：
马抖动综合征是一种鲜为人知的神经性疼痛疾病，表现为无法控制的抖动，轻弹,或头部撞击。治疗选择有限,治疗只是部分成功。目前,缺乏有关南半球头震的流行病学信息。向澳大利亚的摇头马所有者分发了一项在线调查，以收集有关触发因素的信息，症状,季节性,治疗,和感知的治疗效果。反应（n=216）显示症状发作的平均年龄为9.6（±4.7）岁。受影响的凝胶比母马多(76%与24%），与母马相比，凝胶的症状发作较晚（10.1±4.7vs.7.9±4.0年；p<0.01)。明亮的阳光，风,高花粉是最常见的触发因素(61%，46%和40%，分别)，54%的受访者报告了症状的季节性发作。总的来说,71%的受访者表示使用两种或两种以上的治疗方法。最常见的治疗方法是补充剂（68％），鼻网(63%)，遮光面具（48%），车身(48%)和药物化合物(38%)。总的来说,33%的受访者认为治疗无效.调查结果与北半球的调查一致。值得注意的是明亮光线作为主要触发因素的感知，此外，据报道遮光口罩的治疗效果较低。症状的季节性加剧及其与日长的关系值得进一步探索。
