Huntington's disease (HD) is a progressive neurodegenerative disorder that leads to cognitive, behavioral and motor impairment. Physiotherapy can act not only in palliative care, but also in rehabilitation through functional tasks related to the daily needs, aiming to promote more function for the patient. This study aimed to report the experience of physical therapy focused on function in a patient with HD. To assess balance, the Berg Balance Scale (BSE) was used and to measure functionality, the Functional Independence Measure (FIM) was used. Improvement in the patient balance and functionality was observed comparing the before and after treatment. It is concluded that the physical therapy performance in HD has an important role in maintaining the functional aspects, thus improving the quality of life of these patients.
