Table 2 TUG, 6MW and 30 MW test performance, mean (95% CI), of TKA recipients and controls

From: The six-minute walk test is an excellent predictor of functional ambulation after total knee arthroplasty

Walk test   TKA Controls Between group comparison, P
TUG (TKA : n = 29, Controls: n = 42) Time, second (median, IQR) 7.4 (6.3 to 9.0) 5.0 (4.2 to 6.0) <0.001
6MW test (TKA: n = 32; Controls n = 43) Distance, meters 423.5 (380.1 to 466.8) 582.1 (559.9 to 604.2) <0.001
Speed, meters per second 1.18 (1.07 to 1.29) 1.61 (1.55 to 1.67) <0.001
30MW test (TKA n = 32; Controls n = 43) Distance, meters 2108 (1837 to 2381) 3086 (2981 to 3191) <0.001
Average step length, meters 0.68 (0.64 to 0.72) 0.81 (0.78 to 0.83) <0.001
Cadence, steps per minute 112 (107 to 117) 124 (120 to 128) <0.001
