*Graded scale: 1, cannot do it; 2, extremely difficult (pain and instability); 3, difficult (instability only and slight pain); 4, able to do it with some instability and no pain; 5, able to do it with no pain and no instability.
†p values obtained by Kolmogorov‐Smirnov test for non‐parametric variables of small independent samples.
