Although chronic facial dysfunction can be improved with neuromuscular biofeedback therapy, it is uncertain whether this improvement is maintained after such therapy ends, or whether post-therapy, home exercise programs optimize this improvement. We aimed to clarify these issues. Post-therapy facial function, in 38 previously treated patients, was blindly assessed using the House grading system, 1 to 41 months after ending therapy. Results were compared with pre-therapy function. It was found that post-therapy function was better than pre-therapy function in most patients (40%), it was worse in some (26%), and was unchanged in the rest. This surprising result occurred because, although most patients who recently stopped therapy (1 to 6 mo) had improved significantly, the longer other patients were out of therapy, the more they had tended to deteriorate, particularly those who had been practicing. Results suggested that unsupervised, post-therapy, home exercise programs may be detrimental, and that new post-therapy programs may be required to maintain the benefits of regular therapy.
尽管慢性面部功能障碍可通过神经肌肉生物反馈疗法得到改善，但不确定这种改善在治疗结束后是否能持续，也不确定治疗后的家庭锻炼计划是否能优化这种改善。我们旨在阐明这些问题。在38例先前接受过治疗的患者中，治疗结束1至41个月后，采用豪斯分级系统对治疗后的面部功能进行了盲法评估。将结果与治疗前的功能进行比较。结果发现，大多数患者（40%）治疗后的功能优于治疗前，部分患者（26%）治疗后的功能更差，其余患者则无变化。出现这一惊人结果的原因是，尽管大多数近期停止治疗（1至6个月）的患者有显著改善，但其他患者停止治疗的时间越长，他们的功能越倾向于恶化，尤其是那些一直在进行锻炼的患者。结果表明，无监督的治疗后家庭锻炼计划可能有害，可能需要新的治疗后计划来维持常规治疗的效果。
