Both drops feature a crisp, straight drop with adjustable tension.  The difference is the cushion surface.

The Extremity Drop (with a flat cushion) is ideal for adjusting shoulders, elbows, wrists, knees, ankles, etc.  The Speeder Board (with a raised “bump” on the surface) is a valuable tool for students to practice their adjusting technique.

Designed by Dr. Thuli in 1982 while attending Palmer College, these drops have withstood the test of time and will serve you well!
