Objective:
The aim of this study is to cross-culturally adapt the Lymphoedema Functioning, Disability and Health Questionnaire Lymphoedema (LYMPH-ICF) instrument into Brazilian Portuguese and conduct a pilot application (n = 10), without psychometric pretensions.
Method:
Methodological research was conducted, following the steps of translation, synthesis, back-translation, and evaluation by the expert committee. Two translators, two back-translators, and twelve professionals participated in the expert committee. A pretest was carried out with 10 patients with secondary lymphedema due to breast cancer. The degree of agreement was determined by the content validity coefficient.
Results:
It was necessary to modify 8 out of the 29 questions comprising the questionnaire, which exhibited idiomatic disagreement. However, despite these changes, there were no indications of impairments, as content reliability was achieved through a validity coefficient of 0.90.
Final Considerations:
The instrument was successfully translated and cross-culturally adapted for Brazil with a high level of agreement.

The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
