In carpal tunnel syndrome (CTS) distribution of paresthesias is related to the degree of the nerve impairment. To improve the clinical ability in detecting the damage severity, we have introduced the criteria "distribution of paresthesias" in a previous clinical scale: the historical-objective scale (Hi-Ob).
We evaluated 100 consecutive patients (40 bilateral CTS) to validate a five stages clinical scale: the Historical-objective-distribution based scale (Hi-Ob-Db). We compared the Hi-Ob-Db with a validated neurophysiological classification and with the Boston Carpal Tunnel Questionnaire (BCTQ). The BCTQ evaluates two domains, one assessing symptoms (SYMPT=patient-oriented symptom), and the other analysing "functional status" (FUNCT=patient-oriented function).
The positive correlation between the Hi-Ob-Db and neurophysiological findings (p<0.001, r:0.79) was stronger than correlation between the Hi-Ob and the neurophysiological classification (p<0.001, r:0.74). A linear correlation between the Hi-Ob-Db and the patient-oriented scores was observed, respectively FUNCT (p<0.003, r:0.38) and SYMPT (p<0.002, r:0.30).
The Hi-Ob-Db is a clinical scale which correlates with the neurophysiological impairment of the median nerve and with patient-oriented findings in patients with CTS.
The new scale may be useful in routine examination and for scientific purposes.
在腕管综合征（CTS）中，感觉异常的分布与神经损伤的程度有关。为了提高检测损伤严重程度的临床能力，我们在之前的临床量表中引入了“感觉异常分布”标准：历史-客观量表（Hi-Ob）。
我们评估了 100 例连续患者（40 例双侧 CTS），以验证一个五阶段临床量表：基于历史-客观-分布的量表（Hi-Ob-Db）。我们将 Hi-Ob-Db 与经过验证的神经生理学分类和波士顿腕管问卷（BCTQ）进行了比较。BCTQ 评估两个领域，一个评估症状（SYMPT=患者导向的症状），另一个分析“功能状态”（FUNCT=患者导向的功能）。
Hi-Ob-Db 与神经生理学发现之间的正相关（p<0.001，r：0.79）强于 Hi-Ob 与神经生理学分类之间的相关性（p<0.001，r：0.74）。观察到 Hi-Ob-Db 与患者导向评分之间的线性相关性，分别为 FUNCT（p<0.003，r：0.38）和 SYMPT（p<0.002，r：0.30）。
Hi-Ob-Db 是一种与正中神经神经生理学损伤和 CTS 患者患者导向发现相关的临床量表。
新量表可能在常规检查和科学研究中有用。
