Postural spinal balance defined by net intersegmental moments: Results of a biomechanical approach and experimental errors measurement

Table 3 Summary of differences imposed by the “radiographic” posture compared with the free standing

		Cervical	Thoracic	Lumbar
Volunteer 1	Mean Diff FSP vs RX (N/m)	1.15	2.79	0.35
	Inter-trial significant diff	Yes	Yes	No
	Inter-session significant diff	Yes	No	No
	Inter-therapist significant diff	Yes	No	No
Volunteer 2	Mean Diff FSP vs RX (N/m)	0.11	0.88	0.3
	Inter-trial significant diff	No	No	No
	Inter-session significant diff	No	No	No
	Inter-therapist significant diff	No	No	No

Mean differences are in absolute values. Difference is considered significant when superior to experimental error measure.
