The participant population will include adults aged 18 years and older who have experienced unilateral or bilateral hand burns and can read and understand Turkish.The main questions this study aims to answer are:

Does the Turkish version of the BHOT demonstrate high internal consistency, test-retest reliability, and construct validity? How strongly are BHOT scores associated with objective hand function measures such as grip strength and sensory evaluation? Participants will not be assigned to comparison groups, as this is a methodological validation study.

Participants will: Complete a sociodemographic information form. Complete the Turkish version of the BHOT and the QuickDASH questionnaire. Undergo objective assessments including hand grip strength using a dynamometer and sensory evaluation using Semmes-Weinstein monofilaments. Participate in repeated assessments at baseline, 1 month, 3 months and 6 months for reliability analyses.
