Clinical Use of Skull Tap Vestibular Evoked Myogenic Potentials for the Diagnoses of the Cerebellopontine Angle Tumor Patients

Figure 2

VEMP waveforms recorded from all 3 subjects. All the waveforms are normalized according to prestimulus EMG activity. In this figure left side recordings are plotted as solid lines while right side recordings are plotted as dashed lines. Abbreviations are used in this figure as follows. AHLB: auditory head lift both ear stimulation recorded bilaterally; AHLL: auditory head lift left ear stimulation recorded bilaterally; AHLR: auditory head lift right ear stimulation recorded bilaterally; FHLB: head lift recording tapper located at forehead recorded bilaterally; MHLL: head lift recording tapper located at left mastoid recorded bilaterally; MHLR: head lift recording tapper located at right mastoid recorded bilaterally.
