The yips are a set of conditions associated with intermittent motor disturbances that affect precision movement, especially in sports. Specifically, skilled golfers suffer from the yips, although its clinical characteristics and pathophysiology have not been well-studied. We surveyed skilled golfers to characterize their yips-related symptoms, to explore potential confounding factors associated with the yips. Golfers' demographic information, golfing-career-related history, musculoskeletal status and manifestations of the yips are surveyed. Among the 1576 questionnaires distributed, 1457 (92%) responses were received, of which 39% of golfers had experienced the yips. The median age and golfing careers were 48 and 28 years, respectively. Golfers who had experienced the yips were older and had longer golfing careers and more frequent musculoskeletal problems than those without experience of the yips. The multivariate logistic regression analysis revealed that a longer golfing career and musculoskeletal problems were independent factors associated with yips experience. More severe musculoskeletal problems were associated with higher odds of experiencing the yips. A positive association between the yips and musculoskeletal problems was also observed. The yips have similar characteristics to task-specific movement disorders, with a detrimental effect caused by excessive repetition of a routine task. These findings support the notion that the yips are a type of task-specific dystonia.
“易普症”是一组与间歇性运动障碍相关的病症，这些障碍会影响精确动作，尤其是在体育运动中。具体而言，技术娴熟的高尔夫球手会患上易普症，尽管其临床特征和病理生理学尚未得到充分研究。我们对技术娴熟的高尔夫球手进行了调查，以描述他们与易普症相关的症状，探索与易普症相关的潜在混杂因素。调查了高尔夫球手的人口统计学信息、与高尔夫职业生涯相关的历史、肌肉骨骼状况以及易普症的表现。在分发的1576份问卷中，收到了1457份（92%）回复，其中39%的高尔夫球手经历过易普症。年龄中位数和高尔夫球职业生涯分别为48岁和28年。经历过易普症的高尔夫球手比未经历过的球手年龄更大、高尔夫球职业生涯更长，且肌肉骨骼问题更频繁。多因素逻辑回归分析显示，更长的高尔夫球职业生涯和肌肉骨骼问题是与易普症经历相关的独立因素。更严重的肌肉骨骼问题与经历易普症的更高几率相关。易普症与肌肉骨骼问题之间也观察到正相关。易普症与特定任务运动障碍具有相似特征，由日常任务的过度重复导致有害影响。这些发现支持了易普症是一种特定任务性肌张力障碍的观点。
