Body surface gastric mapping
Body surface gastric mapping (BSGM) is a noninvasive electrophysiological method recording the stomach's electrical activity from an array of abdominal electrodes, assessing dyspepsia, nausea, vomiting, and gastroparesis.
Challenge testing
Challenge testing is a diagnostic procedure in which a suspected food or drug is given under medical supervision to confirm or exclude allergy when other tests are unclear.
Electronystagmography
Electronystagmography (ENG, electrooculography) is an electrode-based test recording eye movements via the corneo-retinal potential to evaluate vestibular and oculomotor nerves in dizziness; largely replaced by videonystagmography but still used when eyes-closed recording is needed.
Electrooculography
Electrooculography (EOG) is a non-invasive recording technique that tracks eye movements and tests retinal pigment epithelium function by measuring the eye's corneoretinal standing potential with skin electrodes.
Esophageal impedance pH monitoring
Esophageal impedance pH monitoring is a diagnostic test recording impedance and pH in the esophagus for 24 hours or more to detect and classify reflux episodes.
Eye Movement Measurements
Eye movement measurements: methods for recording eye movements (MeSH D053483, 2007), spanning electro-oculography, scleral search coil, infrared oculography, and video-oculography, used clinically and in wearable eye tracking.
Posturography
Posturography is a clinical method measuring postural control while standing, recording sway on a force platform to evaluate balance disorders; forms include static and computerized dynamic posturography.
Pulse wave analysis
Pulse wave analysis (PWA), including pulse wave velocity, is a family of noninvasive cardiovascular tests recording arterial pulse waveforms to estimate aortic stiffness, central blood pressure, and cardiovascular risk.
Shuttle run test
The shuttle run test is a field exercise test in which participants run between two markers at audio-paced speeds rising in stages until exhaustion, estimating aerobic capacity or agility.
Vestibular stimulation
Vestibular stimulation activates the inner-ear balance organs by caloric, galvanic, or rotational means, to test vestibular function or treat balance disorders; caloric testing was first described by Robert Bárány.
