Notes: + means presence of symptom or sign. - means absence of symptom or sign. Total values are presented as %, and mean ± SD or median (IQR). *Patient numbering is equal to the numbering as used in Table 2. ^#Since patient 3 has upper leg amputation on both sides, motor abnormalities are not assessable.

Abbreviations: IQR, interquartile range; NA, not applicable; ROM, range of motion; SD, standard deviation.
