Table 3.

Correlations between TS magnitudes calculated by 3 different methods (n=19).

TSmag TSmag1 TSmag2
TSmag r = 1 r = 0.85 r = 0.91
p < .0001 p < .0001
TSmag1 r = 0.85 r = 1 r = 0.72
p < .0001 p = 0.0007
TSmag2 r = 0.91 r = 0.72 r = 1
p < .0001 p = 0.0007

Abbreviations:

r: Pearson Correlation Coefficient

p: Probability > |r| under H0: Rho=0

TSmag: Magnitude of TS calculated by subtracting pain of first pulse from peak pain.

TSmag1: Magnitude of TS calculated by subtracting pain of first pulse from that of last pulse.

TSmag2: Magnitude of TS calculated by taking the slope of the change in pain over the change in time, between the first and the last pulse.
