Average daily steps (avDS) could be a valuable indicator of real-world ambulation in people with Parkinson disease (PD), and previous studies have reported the validity reliability this measure. Nonetheless, no study has considered phenotype, stage, severity when assessing consumer wrist-worn devices to estimate step count unsupervised, free-living conditions PD. This aims assess compare smartwatch (Garmin Vivosmart 4) counting avDS PD among phenotypes, stages, groups. A total 104 were monitored through Garmin 4 for 5 consecutive days. Total recorded calculated. Participants dichotomized into tremor dominant (TD; n=39) or postural instability gait disorder (PIGD; n=65), presence (n=57) absence (n=47) tremor, mild (n=65) moderate (n=39) severity. Based on modified Hoehn Yahr scale (mHY), participants further earlier (mHY 1-2; n=68) intermediate 2.5-3; n=36) stages. Intraclass correlation coefficient (ICC; 3,k), standard error measurement (SEM), minimal detectable change (MDC) used evaluate each subgroup. The threshold acceptability was set at an ICC ≥0.8 lower bound 95% CI ≥0.75. 2-tailed Student t tests independent groups analysis 83.4% overlap between group pair. Reliability measured days acceptable overall population 0.89 (95% 0.85-0.92), SEM below 10%, MDC 1580 per day (27% criterion). In all investigated subgroups, also (ICC range 0.84-0.94).

BACKGROUND Average daily steps (avDS) could be a valuable indicator of real-world ambulation in people with Parkinson’s disease (PwPD) and previous studies reported the validity reliability this measure. Nonetheless, no study to date has considered phenotype, stage severity when assessing consumer wrist-worn devices estimate step count unsupervised, free-living conditions PwPD. OBJECTIVE To assess compare smartwatch (Garmin Vivosmart 4) counting avDS PwPD among phenotypes, stages, groups. METHODS One-hundred-four were monitored through Garmin 4 for 5 consecutive days. Total each day recorded calculated. dichotomized into tremor dominant (TD) (N=39) or postural instability gait disorder (PIGD) (N=65), presence (N=57) absence (N=47) tremor, mild (N=65) moderate severity. Based on modified Hoeh Yahr scale (mHY), further earlier (mHY 1-2) (N=68) intermediate 2.5-3) (N=36) stage. Intraclass correlation coefficient (ICC) (3, k), standard error measurement (SEM) minimum detectable change (MDC) used evaluate subgroup. The threshold acceptability was set at an ICC ≥ 0.8 lower bound 95% confidence interval (CI) 0.75. Student’s t-tests independent groups analysis 83.4% CI overlap between group pair. RESULTS Reliability measured days acceptable overall population 0.89 (0.85-0.92), SEM% below 10% MDC 1580 steps/day (27% criterion). In all investigated subgroups, also (ICC range 0.84-0.94). However, ICCs significantly (P=.030), (P=.040) (P=.003). Moreover, PIGD without stage, ranging from 1148 1687 (18-25% Conversely, TD SEM >10% criterion values ranged 1401 2263 (30- 33% CONCLUSIONS mild-to-moderate PwPD, are reliable irrespective lower. These findings facilitate broader informed implementation as index ambulatory activity
