Introduction

The spinal cord injury (SCI) results in loss of muscles' abilities to generate power, loss of sensation, and loss of the ability to control the bowel and bladder. Efforts of rehabilitation are concentrated on preventing secondary complications due to mobility loss. The use of state-of-the-art technology allows providing mechanical assistance for patients to relearn walking or moving arms.

The spinal cord injury treatment was first developed by Theodor Kocher (Switzerland) and William Wagner (Germany), but it all started back in classical times.

History of Spinal Cord Injury Rehabilitation

• Edwin Smith's surgical papyrus in Egypt about 3000 BC describes paraplegia following injury to the spine.
• Hippocrates (circa 460–370 BC) describes traction in the treatment of spinal cord injury.
• Paul of Aegina (AD 625–690) uses a windlass for spine dislocation and suggests laminectomy.
• Avicenna (980–1037) defines paralysis following a spine fracture as a fatal injury

• Roland of Parma (circa 1230) from Salerno used manual extension in the spinal cord injury treatment. He was a pioneer of early intervention
• Ambroise Paré (1564–1598)proposed laminectomy for the treatment of spinal cord injury
• Astley Cooper (1768–1841) and Charles Bell (1774–1842) wanted to introduce a spinal cord injury treatment in London teaching hospitals. Bell focused on accurate diagnostic procedures. According to Bell, the surgery was dangerous. He was teaching that renal failure was the cause of death following a spinal cord injury.
• Henry Cline (1750–1827) first performed laminectomy for the treatment of spinal cord injury.
• Wilhelm Wagner (1848–1900) in Germany developed the first treatment protocol for spinal cord injuries. Together with Paul Stolper (1865–1906), he co-authored a book on spinal cord injury which included the anatomy, the pathology, the mechanism of injury and the practical treatment.
• Theodor Kocher (1841–1917)from Switzerland is known for his research related to the anatomy and physiology of the spinal cord injury
• First World War: helped to develop the concept of the modern management of spinal injuries due to a high number of casualties with spinal cord injury
• Between the war: custodial care for patients with a spinal cord injury continues in the UK post-war
• Charles Frazier (1870–1936) in the US provided a statistical analysis on the outcomes of the surgery, prognosis, life expectancy, and discharge home and work. A page and a half in his book included information on the physical management of spinal cord injury
• George Riddoch (1888–1947) is known for his work on rehabilitation and the pathophysiology of spinal cord injuries.
• Donald Munro (1889–1973) is the father of the treatment of paraplegia.
• Ludwig Guttmann (1899–1980) is considered a founder of the modern treatment of spinal injuries. He formed dedicated spinal cord injury units managing the spine, bladder, bowel, skin, education, and rehabilitation. Conservative management progressed from that of traction, bed rest, and bracing to surgical management and bracing, allowing a shorter time in bed.

Aetiology

• The causes of spinal cord injury include:
  • falls: falls from height or simple falls)
  • motor vehicle accidents (MVA's)/motor vehicle crashes
  • sports-related accidents
  • violence
  • other remaining causes of injury.

MVA's and falls are the most common causes of injury accounting for nearly equal percentages. In developed countries, the main cause of SCI used to be MVA's, but recently are falls. In low-income countries, falls are the most common cause of SCI.

• Patients' demographics
  • Developed countries:
    • male to female ratio: from 1.10:128 to 6.69:121
    • mean age : from 14.630 to 67.631 years

• • Low-income countries:
    • male to female ratio: from 1.00:126 to 7.59:1.29
    • mean age: from 29.532 to 46.033 years
• Level and severity of the injury
  • The most common: the cervical level of spinal cord injury in both developed countries and non-developed countries
  • lower percentage of complete injury vs incomplete injury
  • tetraplegia was more common than paraplegia in both developed countries and non-developed countries
  • motor-complete injuries (America Spinal Injury Association Impairment Scale [AIS]-A or -B) were more common for patients with traumatic SCI, while there were more motor- incomplete injuries (AIS-C or-D) for patients with non-traumatic SCI.
