IPD tremor analysis.

|---|---|---|---|---|---|---|---|---|
| Resting Tremor | Postural Tremor | |||||||
| Intensity (m/s2) | Center Freq. (Hz) | Center Freq. Dispersion (Hz) | Harmonic Index | Intensity (m/s2) | Center Freq. (Hz) | Center Freq. Dispersion (Hz) | Harmonic Index | |

Right side Mean ± SEM |
0.867 ± 0.338 | 6.64 ± 0.367 | 1.93 ± 0.336 | 0.946 ± 0.045 | 0.937 ± 0.377 | 6.10 ± 0.315 | 2.21 ± 0.363 | 0.94 ± 0.058 |
|
Left side Mean ± SEM |
0.633 ± 0.424 | 6.65 ± 0.377 | 1.59 ± 0.346 | 0.944 ± 0.038 | 0.613 ± 0.235 | 6.32 ± 0.323 | 2.24 ± 0.299 | 0.936 ± 0.050 |
Two way ANOVA revealed that neither arm position (resting vs. postural) nor right vs. left had a significant effect on the tremor intensity.
