Histogram displaying the number of patients within each TUG_time interval pre- and post-operatively for men (n = 744) and women (n = 505). Preoperatively, 175 men and 79 women had TUG_time < 13.5 s. Post-operatively the corresponding numbers were 364 and 186. Above this threshold the risk of falling is considered to be increased [23]
