Non-parametric paired Wilcoxon signed rank test was used. There was no significant difference found between the results at baseline and at follow up, apart from FVC.

∞ - the maximum time used for the analysis was infinity, to denote patients who were no longer able to do this test. Abd = abduction, Add = adduction, Flex = flexion, Ext = extension, DF = dorsiflexion, TUG = timed up and Go, 6MWD = six minute walk distance, FVC = forced vital capacity.

^*FVC data from 25 patients.
