Pre-post, single-group.
Writer's cramp (WC) is a focal dystonia causing impairments in daily life. Behavioral treatment approaches have been shown to improve handwriting performance, though outcomes remain sub-optimal.
To examine the effects of the handwriting training and auditory grip force feedback in seven patients with WC.
Handwriting performance was examined before and after treatment. Writing frequency, fluency, and pressure were recorded with a digitizing tablet and grip forces during handwriting were recorded. Subjective writing performance and pain were rated on visual analog scales.
The treatment resulted in significant reductions in writing pressure and pain, while writing performance was significantly improved.
Patients in this study with WC, who exhibit grip force and pressure problems, benefit from feedback-supported handwriting training.
前后对照、单组研究。
书写痉挛（WC）是一种局限性肌张力障碍，会对日常生活造成损害。行为治疗方法已被证明可改善书写表现，尽管结果仍不尽人意。
研究书写训练和听觉握力反馈对7例书写痉挛患者的影响。
在治疗前后检查书写表现。使用数位板记录书写频率、流畅性和压力，并记录书写过程中的握力。主观书写表现和疼痛通过视觉模拟量表进行评分。
治疗使书写压力和疼痛显著降低，同时书写表现显著改善。
本研究中存在握力和压力问题的书写痉挛患者受益于反馈支持的书写训练。
