MVIC=Maximum voluntary isometric contraction; BMI= Body mass index; CAR= Central activation ratio; IE=initial evaluation; 3mos=3 months post‐operative
Note:
*
Pain MVICIE was the subjects’ pain during MVIC at initial evaluation and was assessed with a Verbal Analog Scale. (0‐10, 0= no pain; 10= worst pain)
£PainADL was the degree of pain reported at IE (initial evaluation) and at 3months (3months post TKA) on the Knee Outcome Survey. (0= I do not have pain; 5= Pain prevents me from all daily activities)
