The study which was conducted at the BioMag laboratory at the Helsinki University Hospital, focused on two patients, both with spinal cord injuries caused by trauma. One patient was paraplegic, paralysed from the knees down, and the other was tetraplegic, with some voluntary movement of the hands but no capacity to grasp.
For the study both patients received stimulation treatment given repeatedly for almost six months. This was the first time that attempts were made to rehabilitate patients paralysed as a result of a spinal cord injury through long-term stimulation treatment of this type.
Both patients had been injured more than two years ago and had received conventional rehabilitation treatments throughout their recovery, and continued to do so during the stimulation treatment.
After six months of the stimulation treatment, the paraplegic patient could bend both ankles, and the tetraplegic could grasp an object.
"We observed strengthened neural connections and partial restoration of movement to muscles which the patients were previously entirely unable to use," explained study lead Dr. Anastasia Shulga.
