This questionnaire designed to assess the severity of carpal tunnel syndrome. It consists of two parts:

Part 1 involves the evaluation of hand abnormalities, comprising 11 items (symptom severity score).

Part 2 assesses the loss of hand function and includes another 8 items (function severity score).

Symptom Severity Scale (SSS): The scores for each item are averaged to provide a mean score, ranging from 1-5. Higher scores indicate more severe symptoms.

Functional Status Scale (FSS): The scores for each item are averaged to provide a mean score, ranging from 1-5. Higher scores indicate greater difficulty in performing daily activities.

Part 1, consisting of 5 questions about supervision, self-care, normal activities, medical/discomfort, and coldness/depression. The questions related to medical/discomfort and coldness/depression have 5 options each.
