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

Table 3

Specificity and sensitivity for differentiating controls (the number of patients is 15).

Spirography parameter(s)	Specificity controls	Sensitivity controls
Spiral image (S)	0.79	0.59
Wavelet transform scalogram (W)	0.97	0.89
Tremor spectrum (T)	0.80	0.58
S & T	0.86	0.73
S & T & W	0.93	0.87
