Table 2.

Measures of rigidity including rigidity torque scores and moment-angle plot slopes. Rigidity torque scores are presented for the overall movement (TOTAL) as well as flexion and extension components of the overall movement. Moment-angle plot slopes are presented for the flexion and extension components of the passive movement. Presented as mean (SD)

		Rigidity Work Score			Slope
Trajectory	Medication	Total	Flexion	Extension	Flexion	Extension
CONT	OFF-MED	9.0 (4.2)	5.8 (3.0)	4.0 (1.4)	2.9 (0.6)	2.2 (1.5)
	ON-MED	4.5 (2.1)†	2.1 (2.4)†	3.1 (2.0)	7.4 (4.9)†	7.6 (5.9)†
DISC	OFF-MED	9.4 (3.0)	4.7 (4.2)	3.5 (3.1)	3.5 (1.4)	2.6 (1.1)
	ON-MED	6.4 (3.6)†	2.2 (2.3)†	3.2 (2.7)	6.8 (3.3)†	7.0 (4.0)†

Note:

^*denotes significant difference compared to DISC trajectory;
