Niigata PPPD Questionnaire (NPQ) Online Calculator

Some people feel more dizzy when they stand, walk, move, ride in a car, or look at busy places like stores or scrolling screens. The NPQ asks how much these situations have affected you over the past week. Your score does not give a diagnosis, but it can help show which triggers may be causing the most trouble and help guide a conversation with a healthcare provider.

Why use the NPQ?

The Niigata PPPD Questionnaire (NPQ) helps clinicians understand which common PPPD-related triggers may be affecting a patient’s dizziness. It looks at three main trigger areas: standing or walking, movement, and visually busy environments. The NPQ does not diagnose the cause of dizziness by itself, but it can provide useful context when symptoms are worse with upright posture, motion, riding in a car, scrolling screens, stores, crowds, or other visually complex places. It can also be used to track patient-reported change over time.

Common Clinical Uses

Clinicians may use the NPQ to:

Assess dizziness related to upright standing/walking, movement, or visual stimulation
Identify which symptom triggers are most bothersome
Support baseline documentation and care planning
Guide vestibular rehabilitation goals for motion or visual sensitivity
Measure patient-reported change over time
Document symptom progress during treatment

The purpose of this questionnaire is to identify the difficulties in daily life activities that you may be experiencing due to dizziness. Please move each slider to the number that best describes the extent to which you have been affected during the past week. If you completely avoid performing any of these actions, move the slider to 6.

Movement 0 / 24 Head/body movement and transportation items.

Visual stimulation 0 / 24 Busy visual settings and screen/reading items.

This tool is a screening and symptom-tracking aid. It does not diagnose PPPD or replace care from a licensed healthcare provider. PPPD diagnosis also depends on symptom type, duration, history, and clinical assessment.

The NPQ includes 12 items scored from 0 to 6, with a total score range of 0 to 72. The three subscales are upright posture/walking, movement, and visual stimulation.
In the original validation study, a total score of 27 and a visual stimulation subscale score of 9 were reported as research-based screening cutoffs with the best sensitivity/specificity balance in that sample.
