entity of the perturbation. The limits of stability (LOS) is defined as the distance outside the base of support that can be traveled before a loss of balance occurs. The LOS test is frequently used to quantify this distance and has been suggested as a hybrid between static and dynamic balance assessment. During this test the patient stands on the platform as directed above in the SOT test. The patient watches their movements on a screen so they can see each of the eight LOS targets. The patient begins with their COP directly in the center of the targets (displayed as a figure as a computerized person). At the onset of the test, the patient attempts to lean in the direction of the indicated perimeter target, without lifting their feet, and hold there until the test is complete. According to necessity of the diagnostic workup, CDP can be combined with other techniques, such as electronystagmography (ENG) and electromyography. The main indications for CDP are dizziness and vertigo, and postural imbalances (balance disorders). See also Balance disorders Vestibular system Sources Nashner LM et al.
