Although rotational testing was introduced in 1907, almost as early as the caloric test, it lagged behind the caloric test in clinical practice for decades. However, with advances in computer technology, rotating-chair test systems were developed in the late 1970s and continue to evolve; they are now used in several vestibular testing laboratories.
