Table 3.
The frequency and duration of freezing episodes and the time taken to complete the obstacle course under the off, tonic, and phasic visual cue conditions. Data represent means and standard deviations.
| Visual cue modality | Main effect | Pairwise comparisons | |||||
|---|---|---|---|---|---|---|---|
| Off | Tonic | Phasic | p value | Off vs. tonic | Off vs. phasic | Tonic vs. phasic | |
| FoG frequency (n) | 2.88 (2.69) | 1.82 (2.24) | 1.71 (1.57) | 0.192 | |||
| FoG duration (s) | 28.88 (43.91) | 18.41 (48.41) | 15.35 (36.07) | 0.173 | |||
| Course time (s) | 99.76 (51.83) | 82.65 (55.12) | 81.06 (43.07) | 0.357 | |||
Note. Off = no visual cue; tonic = continuous visual cue (i.e., gait-independent); phasic = FoG-sensitive visual cue (i.e., gait-dependent).
