Wavelet Analysis Increases Sensitivity and Specificity of Spirography for Ambulatory Tremor Discrimination

Table 2

Specificity and sensitivity for diagnosing PT (the number of patients is 20).

Spirography parameter(s)	Specificity PT	Sensitivity PT
Spiral image (S)	0.75	0.65
Wavelet transform scalogram (W)	0.91	0.92
Tremor spectrum (T)	0.71	0.53
S & T	0.82	0.67
S & T & W	0.92	0.88
