CALGARY — Researchers at Foothills Medical Centre (FMC) are the first in Canada to examine the benefits of using an exoskeleton robotic device to rehabilitate patients with spinal cord injuries (SCI) in the days and weeks following their injury.
While previous studies have examined the benefits of using exoskeletons months or years after an SCI, this is the first study to look at the benefits so early during recovery.
This project involves researchers from the Department of Clinical Neurosciences at FMC and the Cumming School of Medicine’s Hotchkiss Brain Institute (HBI).
“The first nine months after a spinal cord injury are pivotal to recovery, so we want to attempt to introduce rehabilitation and mobilization early on and see if it makes a difference,” says lead investigator Dr. Chester Ho,
Head of Physical Medicine and Rehabilitation at FMC and co-leader of the Spinal Cord/Nerve Injury & Pain Neuro Team at HBI. The device, known as the Ekso Bionic Exoskeleton, consists of a metal frame that supports and stabilizes a patient’s torso, core, legs and feet. It is moved robotically by a therapist, enabling patients with a spinal cord injury to get up and walk around. Although it is controlled by remote control, the device offers varying levels of physical control by the patient, depending on the nature and extent of their injury.
Dr. Ho says exoskeletons may potentially promote recovery and reduce complications in SCI patients by reducing loss of bone and muscle mass caused by spending so much time lying down, and also improve breathing and bowel function.
“When it comes to rehabilitation, we often tell people, ‘If you don’t use it, you lose it,’” says Dr. Ho, who is also a member of the O’Brien Institute for Public Health.
Exoskeletons have typically been used in rehabilitation months after an SCI because patients may have other medical conditions or complications shortly after their SCI, or may experience rapidly dropping blood pressure when they stand up.
However, Dr. Ho says the device may be appropriate earlier in the recovery of some patients.
“We believe that taking advantage of exoskeletons early will give many patients the best possible chance at recovery,” he says.
The year-long study, which begins this summer, will include between five and 10 patients selected from across Calgary. It aims to examine whether treatment is safe and feasible in the days and weeks after an SCI. This study will be followed by larger studies involving more patients. Participants in the study will receive 60-minute therapy sessions with the exoskeleton device two to three times a week, for a total of 25 training hours over an eight- to 10-week period. Safety and feasibility outcomes will be monitored and tracked by the research team throughout all sessions.
