To evaluate the validity of the clinical tremor disability interview using a performance-based measure, patient ratings of tremor disability, and bedside tremor severity ratings of upper extremity (UE) action/intention (A/I) and postural (P) tremor.
Sixteen older adult essential tremor patients (mean age=75.4 years, sd=5.7 years) took part in a study evaluating the validity of clinical and self-rating scales of tremor disability. A neurologist obtained bedside clinical ratings of UE A/I and P tremor of each limb and completed a clinical tremor disability rating. A second investigator, blind to neurological exam results obtained a clinical disability rating using the same measure, patient rated tremor disability ratings and conducted a performance-based disability assessment.
Clinical tremor disability ratings were not significantly related to functional performance-based or patient ratings of tremor disability. Bedside clinical ratings of tremor severity also were not associated with clinical or patient-rated tremor disability. Patient ratings were significantly correlated with performance-based ratings.
Further research is needed to validate a brief, sensitive clinical rating scale of tremor disability among older adults. Use of bedside ratings of tremor severity may be problematic and possibly estimate tremor disability. Empirical evaluation of differences in rating methods needs to be directly addressed.
使用基于表现的测量方法、患者对震颤残疾的评分以及上肢（UE）动作/意向（A/I）和姿势（P）震颤的床边震颤严重程度评分，评估临床震颤残疾访谈的有效性。
16名老年特发性震颤患者（平均年龄 = 75.4岁，标准差 = 5.7岁）参与了一项评估震颤残疾临床和自评量表有效性的研究。一名神经科医生对每个肢体的UE A/I和P震颤进行床边临床评分，并完成临床震颤残疾评分。另一名研究人员在不知道神经检查结果的情况下，使用相同的测量方法获得临床残疾评分、患者对震颤残疾的评分，并进行基于表现的残疾评估。
临床震颤残疾评分与基于功能表现的评分或患者对震颤残疾的评分无显著相关性。床边震颤严重程度的临床评分也与临床或患者评定的震颤残疾无关。患者评分与基于表现的评分显著相关。
需要进一步研究以验证老年人中一种简短、敏感的震颤残疾临床评分量表。使用床边震颤严重程度评分可能存在问题，并且可能无法准确估计震颤残疾。需要直接解决评分方法差异的实证评估问题。
