I know it's very common for patient with hemiplegia to have sensation problem, but can someone explain me on the cause of this? Is it a peripheral nerve root problem or other thing? Many thanks!

Hi,
it all depends on the cause of the hemiplegia. Remember that hemiplegia is not a diagnosis but merely a symptom.
If the hemiplegia is caused by e.g. a Stroke, the damage is central. Go back to your neuro anatomy and check the areas of the brain that are responsible for sensation and the blood vessels that supply them. :) Sensory loss after a stroke is indeed very common. Look e.g. at the MCA and review the areas that this artery supplies. If a stroke occurs somewhere along the MCA, all these areas will be affected.
If the hemiplegia caused by a Spinal Cord Injury, than you have a peripheral problem and the sensory fibres might be affected as well. SCI also commonly have a loss of sensation and the area depends on the level and severity of injury; however, SCI hemiplegia is not very common.
Hope this helps for a start,
cheers,
