Assessing forces during spinal manipulation and mobilization: factors influencing the difference between forces at the patient-table and clinician-patient interfaces

Table 3 Difference between forces at the patient-table interface and the clinician-patient interface (F_diff) for each SMT force-time profile

Force-time profiles^a	F_diff			Participants showing greater force at the patient-table interface (n)	Participants showing greater force at the clinician-patient interface (n)
Force-time profiles^a	Mean^b	SD	Range
SMT1	15.56 N	4.86 N	5.35 N to 26.09 N	33	0
SMT2	4.74 N	6.72 N	−7.35 N to 29.06 N	26	7
SMT3	36.70 N	10.02 N	10.45 N to 56.82 N	33	0
SMT4	16.74 N	14.13 N	−8.41 N to 68.04 N	31	2
MOB1	8.77 N	12.34 N	−11.22 N to 57.82 N	26	7
MOB2	7.12 N	10.74 N	−8.58 N to 47.10 N	26	7

^a The list refers to the force-time profiles presented in Table 1
^b A positive F_diff denotes that the force measured at the patient-table interface was greater than the force measured at the clinician-patient interface
