Suppression Head IMpulse Paradigm (SHIMP) test
Along with the video Head Impulse Test or Head Impulse Test, the SHIMP test helps the operator to
determine residual vestibular function. This test resembles the lateral vHIT test and assesses the lateral
semicircular canals. A laser target is used as the suppression medium for the SHIMP test.
The vHIT goggle is placed on the patient's head as in other vHIT tests. The eye is centered in the viewing
area taking care that the reflections are beneath the pupil. After adjusting the patient and calibrating and
centering the laser fixed dots on the wall, you are ready to begin the SHIMP test.
Test preparation:
The head-fixed laser projects a 5-dot pattern on the wall as used for calibration. Instruct the patient to focus
on the center dot for fixation and align the center dot to the wall-fixed dot (for traditional vHIT testing).
SHIMPs are performed on the lateral canal by turning the head 7 – 25 (depends on preset numbers) times at
high velocities to the left and right sides.
