  • *For the purposes of this study, a stroke was defined as any acute cerebrovascular accident (ischaemic or haemorrhagic).

  • †Ability to transfer was assessed by asking the patient to independently transfer from the wheelchair to bed without assistance. A patient who could transfer was classified as a HLP; otherwise he/she was classified as a LLP.

  • CMM, conventional medical management; HLP, high-level functional patient; ITB, intrathecal baclofen; ITT, intention-to-treat; LLP, low-level functional patient.
