Fig. 4From: A portable isometric knee extensor strength testing device: test-retest reliability and minimal detectable change scores of the Q-Force ӀӀ in healthy adultsMean with 95% confidence interval (plotted to one side) of the three trials at the Q-Force ӀӀ of the test and retest. A Peak force; B The average force of the plateau phase; C Peak Torque; D The average torque of the plateau phase. *Trial 1 is significantly different from trial 2 and 3 in Bonferroni post hoc tests (P-value< 0.05)Back to article page
