SWELL SPOTS, KATINA LARGE, EACH Originally designed by Katina Kirby, ORT/L, MS, CLT-LANA, for use along the ulna. Now in two size. The tapered shape makes the Katina useful in treating many difficult areas, such as addressing the stubborn indurate tissue along the ulnar aspect of the forearm, along the IT band of the lateral thigh, and padding the anterior surface of the calf. Create a muff by placing three Katina Swell Spots in a tri-folded stockinette.
