Study characteristics of the ACLR group—TTDPM (n = 4)

Study	Groups	Months after injury	TTDPM set-up	Starting angle and direction of movement
Roberts et al. [41]	ACLR = 20 HC = 19	24	Lateral recumbent position 0.5°/s	Start at 20° and 40° TF and TE
Bonfim et al. [42]	ACLR = 10 HC = 10	18	Supine position 0.5°/s	Start TF at 0°, 15°, 30°, 45°, 60° Start TE at 15°, 30°, 45°, 60°
Ozenci et al. [46]	ACLR = 20 HC = 20	16.5 ± 5.5	Seated 1°/s	Start at 15° TE and TF
Laboute et al. [47]	ACLR = 32 HC = 32	6	Seated 4°/s	Start at 15° TF

ACLR anterior cruciate ligament reconstructed, HC healthy control, TTDPM threshold to determine passive motion, TF towards flexion, TE towards extension
