BACKGROUND: Remote assessment of essential tremor (ET) is unverified. OBJECTIVES: To compare assigned tremor scores from a remote videotaped research protocol with those from an in‐person videotaped research protocol and assess the validity of remote and in‐person videotape‐based diagnoses when compared against the intake diagnosis (ET vs. control). METHODS: Participants with intake diagnoses of ET (11) or controls (15) completed a tremor examination that was filmed both remotely and in person. RESULTS: Agreement between the tremor ratings assigned during remote and in‐person videos was substantial (composite κ(w), 0.67; mean Gwet's AC2 score, 0.92; mean percent agreement, 63.7%). In ET cases with less severe tremor, agreement was lower (p = 0.008). Diagnostic validity was high for both remote and in‐person videos compared to the intake diagnosis. CONCLUSIONS: Remote video is a reasonable alternative to in‐person video for the assessment of tremor severity and assignment of ET diagnoses. However, at low tremor amplitudes, agreement declines. |
