In clinical research, these stages are sometimes assigned scores to quantify healing progress: : 5–6 points (most active) : 4–5 points : 3–4 points : 2–3 points : 1–2 points : 0–1 points (fully healed)
: The defect is significantly smaller, with regenerating epithelium covering most of the ulcer floor. Scarring Stage (S1 & S2) S1 (Red Scar) sakitamiwa classification
This is the most acute phase. The ulcer is characterized by a thick, white slough (exudate) covering the base. The margins are sharp and swollen (edematous), and there are no visible mucosal folds reaching the ulcer. A2 (Active-2): In clinical research, these stages are sometimes assigned
To understand Sakitamiwa, one must adopt an (the insider's view) rather than the etic perspective (the outsider/scientific view). The margins are sharp and swollen (edematous), and
Clinical trials use this to measure the success of therapies (like PPIs or rebamipide) in healing ulcers.
The ulcer is almost gone, with a very small, thin white coating, and regenerative tissue is present. 3. Scarring Stage (S)
