Tele-CE in Severe Stroke

The goal of this clinical trial is to determine the effects of home-based cross-education on lower limb neuroplasticity in severe stroke. The main questions the investigators aim to answer are: * What are the effects of home-based cross-education on lower limb neuroplasticity? * What are the effects of home-based cross-education on lower limb function? * Is home-based cross-education feasible to administer and accepted by participants? Participants will take part in ten home-based, remotely supervised sessions, during which participants will either perform unilateral skill and strength training of the unaffected lower limb (Tele-Cross Education or Tele-CE) or cognitive training and unilateral movements of the unaffected lower limb (Tele-control). Each participant will experience measures of brain and spinal activity and motor function testing before and after both sessions (Tele-CE and Tele-control). Each participant will also be asked to fill out a feedback questionnaire to assess acceptability after intervention sessions (Tele-CE and Tele-control).
