Objective: Onabotulinum toxin A (botulinum A toxin) is utilized to extend flexed extremities in spastic hemiparesis. Injection points are important to obtain a better effect. Injecting botulinum A toxin into the forearm muscles is a standard method for flexed wrist and fingers; however, we developed new injection points in the intrinsic muscles of the hand to acquire more reliable effect. Methods: The authors injected botulinum A toxin into the palmar side of the proximal and middle phalanx of each finger and thenar muscles. Eight patients with poststroke flexed wrist and fingers were treated by this method. Results: In all patients, the spasticity improved to 0 or 1 from 3 or 4 in Modified Modified Ashworth Scale 1 month after the treatment. They were satisfied with our treatment because they could keep their affected fingers hygienic by washing fingers cleanly after the treatment. Conclusions: Our botulinum A toxin injection points for finger spastic paralysis are accurate spots producing great effect to flexed fingers.

Onabotulinum 毒素 A 新注射点治疗手指痉挛性麻痹： 8 例报告。


目的： A型肉毒杆菌毒素（A型肉毒杆菌毒素）用于伸展痉挛性偏瘫患者的屈曲四肢。注射点对于获得更好的效果很重要。将肉毒杆菌毒素注射到前臂肌肉中是弯曲手腕和手指的标准方法；然而，我们在手的内在肌肉中开发了新的注射点，以获得更可靠的效果。方法：作者将 A 型肉毒杆菌毒素注射到每个手指的近节和中节指骨的掌侧和鱼际肌肉中。采用这种方法治疗了 8 例卒中后屈腕手指患者。结果：在所有患者中，治疗后 1 个月，痉挛状态从改良改良 Ashworth 量表中的 3 或 4 改善至 0 或 1。他们对我们的治疗感到满意，因为他们可以通过在治疗后清洁手指来保持受影响的手指卫生。结论：我们的手指痉挛性麻痹肉毒杆菌注射点是准确的点，对弯曲的手指有很好的效果。
