Bath Ankylosing Spondylitis Functional Index

The Bath Ankylosing Spondylitis Functional Index (BASFI) is a tool used by healthcare providers to assess how ankylosing spondylitis (AS) affects a person's daily life and physical abilities. It consists of a questionnaire that asks individuals about their ease in performing daily tasks, such as bending, sitting, or walking. The results help doctors understand the severity of the condition and monitor changes over time. It is an important part of managing AS, enabling targeted treatments to improve the patient's quality of life.
