The Unified Dystonia Rating Scale (UDRS) was designed to include a more detailed assessment of the severity of dystonia in individual body areas. Each of 14 body regions are rated for dystonia severity and duration. The proximal and distal limbs are given separate ratings. Ratings for each body region are totaled for an overall rating of dystonia severity. The UDRS was tested in a large sample of dystonia patients at multiple sites exhibiting the full spectrum of dystonia severity.

Inclusive Language in Clinical Outcome Assessments

Healthcare providers should tailor the language used in COAs to reflect each patient’s gender identity. In grammatically gendered languages, the practice includes making appropriate linguistic adjustments to ensure communication is respectful and inclusive throughout the assessment process.
