The hanger reflex is an interesting phenomenon in which a wire hanger placed on the
head induces head rotation. The authors focused on the relationship between the hanger
reflex and the vestibulo-ocular reflex (VOR) and reported interesting findings showing
that the gain of the VOR was altered in the video head impulse test in the lateral
semicircular canal [
[1]
]. A recent experimental study showed that the hanger reflex can be elicited even
when pure skin shear deformation alone was applied [

[2]
]. Studies have also shown that the hanger reflex can be elicited at sites other than
the head [

]. Since this non-head hanger reflex cannot be explained by the VOR, changes in the
VOR—at least at sites other than the head—are not likely to be the primary cause.
Regarding the head, we considered the possibility that the change in the VOR was caused
by the hanger reflex. Devices inducing the hanger reflex have been used for the treatment
of symptoms not only in cervical dystonia but also in areas other than the head, and
their potential application in the treatment of neurological disorders is immeasurable
