Symptoms of paralysis

Paralysis can be classified in a number of different ways. For example, it can be localised, affecting a particular part of the body, or generalised, affecting a wider area.

Examples of localised paralysis include:

• facial paralysis which is usually limited to one side of the face
• paralysis of the hand
• paralysis of the vocal cords vocal cords are bands of tissue and muscle used to generate speech; paralysisusually only affects one vocal cord, which means theperson isable to speak but their voice will behoarse

Examples of generalised paralysis include:

• monoplegia where one limb is paralysed
• hemiplegia where the arm and leg on oneside of the bodyare paralysed
• paraplegia where both legs are paralysed, or sometimes the pelvis and some of the lower body
• tetraplegia (also known as quadriplegia) here both the arms and legs are paralysed

Temporary andpermanent paralysis

Paralysis can either be temporary or permanent.

Facial paralysis isa relatively common cause of temporary paralysis thatcauses temporary facial paralysis.

Sometimes paralysis that occurs after astroke canalso be temporary.

Paralysiscaused byserious injury, such as a broken neck, is usually permanent.

Partial or complete paralysis

Paralysis can be:

• partial where there is some muscle function and sensation; for example, ifa personcan move one leg but not the other,or feel sensations such as cold and heat
• complete where there is complete loss of muscle function and sensation in affected limbs

Spastic or flaccid paralysis

Paralysis can be:

• spastic wheremuscles inaffected limbs are unusually stiffor display spasms, and movements are not under the control of the individual (read about spastic paraplegia )
• flaccid where muscles inaffected limbs are floppy and weak;muscles in flaccid paralysis may shrivel

People with spastic paralysis may experience muscle weakness withspasms (involuntary muscle contractions).People with flaccid paralysis often experience muscle weakness without spasms.

In some conditions, such as motor neurone disease or cerebral palsy , it is possible to experience episodes of spastic paralysis followed by flaccid paralysis, or the other way around.

Levels of spinal cord injury

Whenassessing the extent ofa spinal cord injury, it is a case of determining where onthe spine the injury occurred,and how badlyrelated nerves and muscles have been affected.

The spinal cord is measured using a number and lettering system based on the vertebrae (disc-shaped bones that help support the spine and neck).

Your spine is made up of 24 vertebrae in total, consisting of:

• sevencervical vertebrae in the neck measured as C1 to C7
• 12 thoracic vertebrae in your chest area measured as T1 to T12
• fivelumbar vertebrae in your lower back measured as L1 to L5

People with a spinal cord injury between C1 and C7 are likely to have paralysis in all four limbs (tetraplegia).

The extent of the paralysis and subsequent loss of muscle function will depend on how high up the injury occurred. For example:

• someone with a C1 to C4 spinal cord injury will have little or no movement in their limbs and will probably only be able to move their head and possibly their shouldersthey will also need a ventilator to assist their breathing
• someone with a C7 spinal cord injury will be able to extend their elbows and may have some movement in their fingers
• someone with a T2 to T12 spinal cord injury will have fully functional muscles in the top half of their body, but little or no function in their lower limbs and will needa wheelchair
• someone with an L1 to L5 injury could have limited movement in their hips, knees and feet, butis likelyto need a wheelchair or other type of mobility aid, such as a walking frame
