Impairment of motor and sensory functions in the lower limbs
Medical condition
Paraplegia
, or
paraparesis
, is an impairment in
motor
or
sensory function
of the lower extremities. The word comes from
Ionic Greek
(
παραπληγ?η
)
"half-stricken".

It is usually caused by
spinal cord injury
or a
congenital
condition that affects the neural (brain) elements of the
spinal canal
. The area of the spinal canal that is affected in paraplegia is either the
thoracic
,
lumbar
, or
sacral
regions. If four limbs are affected by paralysis,
tetraplegia
or quadriplegia is the correct term. If only one limb is affected, the correct term is
monoplegia
.
Spastic paraplegia
is a form of paraplegia defined by
spasticity
of the affected muscles, rather than
flaccid paralysis
.
The
American Spinal Injury Association
classifies spinal cord injury severity in the following manner. ASIA A is the complete loss of sensory function and motor skills below the injury. ASIA B is having some sensory function below the injury, but no motor function. In ASIA C, there is some motor function below the level of injury, but half of the muscles cannot move against gravity. In ASIA D, more than half of the muscles below the level of injury can move against gravity. ASIA E is the restoration of all neurologic function.

Treatment
[

]
Individuals with paraplegia can range in their level of
disability
, requiring treatments to vary from case to case. Rehabilitation aims to help the patient regain as much functionality and independence as possible. Physiotherapy may help to improve strength, range of motion, stretching and transfer skills.
[2]
Most paraplegics will be reliant on a wheelchair as a mode of transportation.
[3]
Activities of daily living
(ADLs) can be quite challenging at first for those with a
spinal cord injury
(SCI). With the aid of physiotherapists and occupational therapists, individuals with an SCI can learn new skills and adapt previous ones to maximize independence, often living independently within the community.

Regeneration of the spinal cord
[

Olfactory ensheathing cells
(OEC) have been transplanted with success into the spinal cord of a Polish man named
Darek Fidyka
, who was the survivor of a knife attack that left him paraplegic in 2010.
[5]
In 2014, Fidyka underwent pioneering spinal surgery that used nerve grafts, from his ankle, to 'bridge the gap' in his severed spinal cord and OEC's to stimulate the spinal cord cells. The surgery was performed in Poland in collaboration with Prof. Geoff Raisman, chair of neural regeneration at University College London's Institute of Neurology, and his research team. The olfactory cells were taken from the patient's olfactory bulbs in his brain and then grown in the lab, these cells were then injected above and below the impaired spinal tissue.
[6]
Fidyka regained sensory and motor function in his lower limbs, notably on the side of the transplanted OEC's. Fidyka first noticed the success three months after the procedure, when his left thigh started gaining muscle mass. MRIs suggest that the gap in his spinal cord has been closed up. He is believed to be the first person in the world to recover sensory function from a complete severing of the spinal nerves.

The 38-year-old, who is believed to be the first person in the world to recover from complete severing of the spinal nerves, can now walk with a frame and has been able to resume an independent life, even to the extent of driving a car, while sensation has returned to his lower limbs.
