Correlations (Spearman’s rho) between post-operative change in TUG_time, TUG_steps and 10MWT, miNPH, mRS and MMSE. All correlations were statistically significant. Δ = Pre/post difference, n = number of patients and R = correlation constant
^a10MWT is measured in s when correlated to all scales but TUG_steps, when it is measured in steps. All correlations were statistically significant
