Crosswalk #6: Four Square Step Test (4SST) and Haas Balance Book

The 4SST is a dynamic balance test that assesses a patient’s ability to step over small obstacles forward, backward, and to each side. The Haas Balance Book: 100+ Exercises for PTs & OTs is a collection of over 100 exercises to improve static, dynamic, and reactionary balance. Based on results of the 4SST, exercises can be selected (from the book or elsewhere) that target elements of the 4SST noted to be slow and/or unsteady. Elements of the 4SST include stepping in clockwise manner over small obstacles (right side, backwards, left side, and forwards). Sequence is repeated in counterclockwise direction. Efforts are made during stepping to move quickly, avoid hitting foot on obstacles, and to face forward during test. Exercises that more closely simulate slow, unsteady, or difficult elements of the 4SST will have a higher potential for positive training benefits. The crosswalk below references exercises from Haas Balance Book that help simulate aspects of the 4SST:
