Table 4. The Five Predictors of a Novel Clinical Prediction Rule for Independent Ambulation Outcomes After Traumatic Spinal Cord Injury³² .

Variablea	Range of Test Scores	Weighted Coefficient	Minimum Score	Maximum Score
Age ≥ 65 y	0–1b	−10	−10	0
Motor score, myotome L3	0–5c	2	0	10
Motor score, myotome S1	0–5c	2	0	10
Light touch score, dermatome L3	0–2d	5	0	10
Light touch score, dermatome S1	0–2d	5	0	10
Total			−10	40

^aOnly the best score of each myotome or dermatome (i.e., right or left) should be applied for the prediction rule (see text).

^b0 = no, 1 = yes.

^cGraded on a 5-point scale adapted from the “Medical Research Council” scale.

^d0 = absent, 1 = impaired, 2 = normal.¹²
