Impaired Modulation of Motor and Functional Performance in Patients after Total Knee Arthroplasty: A Prospective Observational Study

Table 2

Maximal performance for respective tasks with the associated pain level by group and time-point.

	HP ()	TKA ()		value (T0 vs. T1 in TKA)
	T0	T0	T1
PT involved (nm); PT angle (°)	^§§			<0.001
PT uninvolved (nm); PT angle (°)	^§§			0.631
OSmax ()	^§§			<0.001
Speedmax (m/s)	^§§			<0.001
VAS-PT involved (0-10)	^§§			0.121
VAS-PT uninvolved (0-10)	^§			0.667
VAS-OSmax (0-10)	^§§			0.032
VAS-Speedmax (0-10)	^§			1.000

Legend. Data are shown as . values refer to the comparison between T0 and T1 (simple effect analysis for ANOVA interactions for PT involved and PT uninvolved, paired -test with Bonferroni correction for OS_max, Speed_max, and VAS during all tasks). Differences between groups are also shown (unpaired -test with Bonferroni correction). Abbreviations. TKA: total knee arthroplasty; HP: healthy participants; PT: peak torque during knee extension; OS_max: maximum overshoot during STS; Speed: maximum speed during 10MWT; VAS: visual analogue scale. Symbols legend: HS vs. TKA at T0 (); HS vs. TKA at T0 (); ^§HS vs. TKA at T1 (); ^§§HS vs. TKA at T1 ().
