Exoskeleton for Post-Stroke Recovery of Ambulation

Use of a Robotic Exoskeleton to Promote Walking Recovery After Stroke - Phase 2

To determine the effect of using a robotic exoskeleton to allow walking practice after stroke, compared to usual physiotherapy care, on recovery of walking ability and secondary outcomes.

Participants admitted to inpatient stroke rehabilitation for physiotherapy services will be randomly assigned to either the Exoskeleton Program or Usual Care Program.

Individuals in the Exoskeleton Program will have their usual physiotherapy sessions replaced with the exoskeleton intervention. The exoskeleton will allow standing and walking from the first sessions in rehabilitation, as the exoskeleton provides the physical support to allow walking in full weight-bearing without being limited by therapist fatigue and lifting requirements. Individuals in the Usual Care Program will receive standard physiotherapy care, which is individualized and hands-on with their therapist to regain walking, mobility, and independent function.

Both groups will be conducted 3-5 days a week, 30-60 minutes per session until discharge (to a maximum of 8 weeks). Participants will be assessed at baseline, discharge, and 6-months after starting rehabilitation.

Inclusion Criteria:

• Stroke within last 3 months
• One-sided hemiparesis
• 19 years or older
• Requires 2-person assist to walk
• Able to communicate and follow instructions
• Prescribed to receive physiotherapy care

Exclusion Criteria:

• Stroke of non-vascular origin (e.g. tumour, infection)
• Significant musculoskeletal or other neurological condition
• Co-morbidities that would preclude activity
• Pregnant
• Unable to walk prior to stroke
• <60 inches or >74 inches in height
• >220 pounds in weight
• Joint contractures or spasticity that would limit safe use of the Ekso exoskeleton
