Smartphone-based finger-tapping test

1. Smartphone-based finger-tapping test is associated with mechanical finger-tapping test in humans (r = 0.70, 95% CI [0.52, 0.82]).

   “mApp‐FTT was associated with manual FTT on iOS ( r = 0.70, 95% CI [0.52, 0.82], p < .001)”

1. Smartphone-based finger-tapping test predicts CDR®+NACC-FTLD Box Score in humans (r = -0.46, 95% CI [-0.66, -0.22]).

   “as did disease severity (CDR®+NACC‐FTLD Box Score; r=‐0.46, 95% CI [‐0.66, ‐0.22], p < .001).”

1. Smartphone-based finger-tapping test predicts Unified Parkinson's Disease Rating Scale in humans (r = -0.48, 95% CI [-0.66, -0.28]).

   “Total UPDRS score correlated with lower mApp‐FTT ( r = ‐0.48, 95% CI [‐0.66, ‐0.28], p < .001)”

1. Smartphone-based finger-tapping test predicts Progressive Supranuclear Palsy Rating Scale in humans (r = -0.60, 95% CI [-0.75, -0.39]).

   “Among iOS users, total PSPRS score was negatively correlated with mApp‐FTT ( r = ‐0.60, 95% CI [‐0.75, ‐0.39], p < .001).”
