Table 8.

The performance (%) of LDA in classifying the high-risk subgroup from low-moderate risk (mean ± SD), by 2 different models. Model1: data related to movement of patients in extension in a plane of 15° rotation to the right. Model2: data related to movement of patients in extension in planes of 15° rotation to the right and 30° rotation to the left.

	Model 1	Model 2
High vs. Low-Moderate risk	66.9 ± 2.1	65.7 ± 3.3

Discrimination analysis for high risk vs. low-moderate risk was repeated 10 times, the mean ± standard deviation is shown in the table.
