In uncontrolled studies, several behavioural methods, including habit reversal, were said to be useful in writer's cramp. In this controlled study, 23 subjects with writer's cramp recruited from a neurology clinic were randomly allocated to five sessions over four weeks of either habit reversal training or a control treatment of relaxation training. Three subjects dropped out. Twenty patients (9 habit reversers, 11 controls) completed the trial up to three months follow-up. Outcome measures included observation of writing within the session, assessment of writing tasks completed at home, and blind ratings by an independent assessor. The results showed that habit reversal was no better than relaxation. Taking both treatments together, patients improved to three months follow-up on seven of nine measures, but remained substantially handicapped.
在非对照研究中，包括习惯逆转训练在内的几种行为方法据说对书写痉挛有效。在这项对照研究中，从一家神经科诊所招募的23名书写痉挛患者被随机分配，在四周内接受五个疗程的习惯逆转训练或放松训练对照治疗。三名受试者退出。20名患者（9名习惯逆转训练组，11名对照组）完成了试验，随访期长达三个月。结果指标包括观察疗程中的书写情况、评估在家完成的书写任务，以及由一名独立评估者进行盲法评分。结果显示，习惯逆转训练并不比放松训练效果更好。两种治疗方法结合使用时，患者在九个指标中的七个指标上到三个月随访时有所改善，但仍有严重的功能障碍。
