A novel method of measuring passive quasi-stiffness in the first metatarsophalangeal joint

Table 1 Intra-rater (n = 13) and inter-rater (n = 10) reliability of first metatarsophalangeal joint (MTPJ) quasi-stiffness

Rater	Mean ± SD (Range) [Nmm/degrees]	Mean ± SD (Range) [Nmm/degrees]	Mean Difference ± SD [Nmm/degrees]	SEM [Nmm/ degrees]	ICC
Intra-rater	Session 1	Session 2
	14.9 ± 14.6	14.2 ± 8.5	-0.68 ± 11.4	7.71	.568
	(0.66–53.4)	(2.72–30.5)	-0.68 ± 11.4	7.71	.568
Inter-rater	Experienced	Inexperienced
	12.6 ± 8.4	19.9 ± 9.2	7.36 ± 15.7	11.29	-.447
	(2.72–30.5)	(7.14–36.7)	7.36 ± 15.7	11.29	-.447

Mean Difference was calculated from Mean (Session 2)—Mean (Session 1) or Mean (Inexperienced)—Mean (Experienced)
SD standard deviation, SEM standard error of measurement, ICC intraclass correlation coefficient
