孤独症谱系障碍儿童情绪面孔识别的眼动轨迹

目的 采用眼动技术探索孤独症谱系障碍(ASD)患儿情绪面孔识别的眼动轨迹。方法 选取ASD和典型发育(TD)被试随机呈现QQ糖图片和5种情绪面孔图片,使用眼动仪记录眼动指标,考察ASD组和TD组在不同情绪类型和兴趣区域的眼动轨迹的差异。结果 1)ASD患儿对情绪面孔的注视时间显著低于TD组儿童;2)相比TD组,ASD组更多的观看面孔非核心区,更少的注视嘴巴和眼睛;3)孤独症注视眼睛与行为问题呈正相关,对嘴部的注视与社交能力呈正相关。结论 1)ASD儿童具有与TD儿童相似的眼动模式,但是注视时间更短;2)ASD以注视嘴部作为完成社交相关任务的补偿策略。     

Lumbar disc syndrome in Finland.

The prevalence of lumbar disc syndrome (herniated disc or typical sciatica) and its consequences in terms of disability, handicap, and need for medical care were studied as part of the Mini-Finland Health Survey. A sample of 8000 persons representative of the Finnish population aged 30 or over was asked to come for examination, and 7217 (90%) participated. A diagnosis of lumbar disc syndrome based on medical history, symptoms, and standardised physical examination was made for 5.1% of the men and for 3.7% of the women. Half of these patients were assessed to be in need of medical care, over 80% of which was considered to be adequately met. One third of all patients with lumbar disc syndrome had been previously hospitalised for that syndrome, and one fifth of the patients had undergone lumbar surgery. At least slight disability was found in almost 60% of the patients, though severe functional limitations were rare. About 6% of the population's work disability was estimated to be attributable to lumbar disc syndrome.
