Every year, 1 in 60,000 people are injured in the cervical spinal cord, with most common causes being the traffic accidents, falls and sports. In the UK every year, there are around 1,200 people with spinal cord injury, half of them with tetraplegia.
Since, the tetraplegia case in MAMEM refers to injuries; it is evident that the age could vary a lot within the selected population. To obtain statistical power, approximately 15 subjects per group will be recruited, while an additional group of people, diagnosed as healthy will participate in the pilot trials for evaluation purposes. The group of healthy people will match the characteristics of the three target groups, matching age and gender.
