Diplegia in the legs
Diplegia of the legs consists of paralysis of both legs. There are 3 levels of severity. Mild diplegia means the person can usually walk but might walk a little differently, can usually play and run to a limited extent. Moderate diplegia means the person can usually walk but with a slight bend in the knees. They usually cant run and have to use the handrails to go up and down steps. People with severe diplegia usually need crutches, a walker, or a wheelchair to be able to get around.Children with diplegia in the legs have a delayed growth in their leg muscles which causes the muscles to be short. This then causes the joints to become stiff and the range of motion to decrease as the child grows. “For the majority of children with diplegia, growth and development are not a problem. Children with diplegia are eventually able to walk, just normally later; they generally attend regular schools and become independently functioning adults.”

Causes
The most common cause of diplegia in the legs is cerebral palsy. Paralysis of the legs may also be caused by trauma, injury, or genetics, but this is very rare. Age of onset
Usually occurs within 2 periods:
With premature babies
full diagnosis usually between ages 2–5 yearsDiplegia is usually not diagnosed before the age of 2 years yet the symptoms and signs of the earlier stages are typical and should enable the diagnosis to be made before the contractures have occurred.
Causes
Facial paralysis is usually caused by traumatic, infectious, neurological, metabolic, toxic, vascular, and idiopathic conditions. While over 50% of the cases of unilateral facial paralysis are caused by idiopathic conditions, less than 20% of bilateral cases are idiopathic. The most common infectious cause of facial diplegia is Lyme disease. Treatment
The treatment for facial diplegia depends on the underlying cause. Some causes are usually treatable such as infectious, toxic, and vascular by treating the main problem first. After the underlying problem is cured, the facial paralysis usually will go away. Diplegia of the arms
People with diplegia in their arms experience difficulties in reaching, pointing, grasping, releasing, manipulating objects and many other motor functions performed by the hands and arms. Causes
There are several ways of getting diplegia in the arms. It is very common for people with cerebral palsy to have diplegia of the arms. Although most people with cerebral palsy have diplegia in their legs, some people have diplegia in their arms. Other ways of getting paralysis of both arms is through a traumatic event or injury. Treatment
There are several different modes of treatment for people with paralysis in their upper limbs. For example, behavioral and environmental treatments may include physiotherapy, occupational therapy, motor learning, strength training, and neurodevelopment treatment. Another treatment may be through the use of splints and casts. Electrophysical agents may be used such as neuromuscular electrical stimulation (NMES). Sometimes pharmacological treatments are necessary such as Botulinum toxin type A. On more severe cases surgery of the upper limbs may be required.
