成功的自主抽动抑制是用于治疗抽动障碍的行为干预的关键组成部分。本研究的目的是检查最近发作的抽搐儿童的抽搐抑制，并确定是否有能力抑制抽搐预测未来抽搐的严重程度。我们测试了45名儿童（30名男性，平均年龄7.74岁）与最近发作的抽搐（平均3.47个月前的第一次研究访问;基线），并重新检查每个孩子在第一次承认抽搐的12个月周年（随访）。在基线访视时，儿童在几种条件下进行抽搐抑制任务：自由抽搐，给予口头请求抑制抽搐，以及在奖励存在的情况下抑制抽搐。在基线访视时，只有几个月抽搐的儿童可以抑制他们的抽搐，当他们得到即时和偶然的奖励时，抽搐抑制尤其成功。此外，在奖励的存在下抑制抽搐的能力预测了随访时抽搐的严重程度。这些研究结果表明，更好的抑制控制抽搐抽搐发作的几个月内可能是一个重要的预测未来抽搐症状的结果。
Successful voluntary tic suppression is a key component of the behavioral interventions that are used to treat tic disorders. This study aimed to examine tic suppression in children with recent-onset tics and determine whether the capacity to suppress tics predicts future tic severity. We tested 45 children (30 male, mean age 7.74 years) with recent-onset tics (mean 3.47 months prior to the first study visit; baseline) and re-examined each child at the 12-month anniversary of the first recognized tic (follow-up). At the baseline visit, children performed a tic suppression task with several conditions: tic freely, inhibit tics given a verbal request, and inhibit tics in the presence of a reward. At the baseline visit, children with tics for only a few months could suppress their tics, and tic suppression was especially successful when they received an immediate and contingent reward. Additionally, the ability to suppress tics in the presence of a reward predicted tic severity at follow-up. These findings suggest that better inhibitory control of tics within months of tic onset may be an important predictor of future tic symptom outcome.
