Table 4 Maximum strength reliability indices in controls and patients

	Controls (n = 26)			Patients (n = 66)
Parameter	ICC_3,1	SEM	SDD%	ICC_3,1	SEM	SDD%
MVIC (kg)
Maximum	0.92 (0.83-0.97)	5.94	18.57	0.91 (0.86-0.94)	6.96	31.61
Mean	0.96 (0.90-0.98)	5.72	18.51	0.96 (0.93-0.97)	6.49	30.75

ICC: Intraclass correlation coefficient; SEM: Standard error of the measurement; SDD: Smallest detectable difference; MVIC: Maximum/mean voluntary isometric contraction.
