Modified head shake sensory organization test: Sensitivity and specificity.

The study included only 30 participants, and the authors say the small sample may not support immediate clinical use. It compared patients with symptoms to healthy controls, which can make a test look better than it would in a mixed clinic group. The healthy controls did not receive caloric testing, so some could have had undetected vestibular problems. The test conditions were presented in a fixed order, not randomised, because the authors wanted a pragmatic clinical sequence. Two patients could not complete the best-performing condition, so it may not work for everyone. Only horizontal head movements were tested, although daily life also involves pitch and roll movements. The authors note learning effects and poor reliability across trials with the EquiTest system. No comparison was made with video head impulse testing because it was not available at the start of the study.

Do not treat this as ready for routine screening. The accuracy came from 30 people, and the best condition could not be completed by two patients.
