This document outlines a clinical trial protocol for using Ayurvedic basti treatment for danda apatanka (axial spondyloarthritis). It assigns patients to two groups, one receiving anuvasana basti and niruha basti on alternating days for one week, the other receiving the same. Improvement will be assessed before and after treatment using several scoring systems and measures for pain, stiffness, fatigue, disability, and indices for ankylosing spondylitis. Exclusion criteria include conditions like sciatica, tuberculosis, pregnancy/lactation, and major systemic diseases. Tests like CRP, ESR, HLA B27 will help diagnose and exclude other conditions.
