A group from Japan have been experimenting using a preclinical (animal) model, to investigate how spinal cords of different ages react to the same compression force. Using a technique called Finite Element Method, more typically used in engineering, they have shown that in an older spinal cord the same amount of compression causes a much higher stress to the spinal cord tissue, than in a younger spinal cord. This was the same for sudden or slow compressive forces.
Of course this experiment has not been conducted on human spinal cords, but the findings are in keeping with a wider experience of aging and CSM and is a further reminder of the need for more sophisticated tools to represent the extent of spinal cord injury in CSM.
