[The application value of suppression head pulse paradigm (SHIMP) in vestibular examination].

Objective: To summarize different results of suppression head impulse paradigm (SHIMP) and head impulse paradigm (HIMP) in patients with bilateral and unilateral vestibular loss and to evaluate the practicability of SHIMP in clinical vestibular examination. Method: Seventy subjects with unilateral vestibular loss, bilateral vestibular loss and healthy were included. Morphological characteristics of HIMP and SHIMP results were analyzed. The differences of VOR gains were compared with the paired t test. Result: Almost all SHIMP showed anti-compensatory saccades in healthy group. Less anti-compensatory saccades occurred in the affected side of patient with vestibular loss. The VOR gains showed there was a significant correlation( P <0.05) between HIMP and SHIMP. Conclusion: Different to compensatory saccades in HIMP indicate potential loss in vestibular function, anti-compensatory saccades in SHIMP shows vestibular function in patients. The combination of these two mthods will benefit disease screening and vestibular rehabilitation in clinical examination.
