How can being stabbed in the back lead to paralysis of the right lower extremity?

This is a question in a case study I have to do for my physio lab, the patient was stabbed in the back at the mid-thoracic level and close to the midline. She lost all sensory functions in her right leg. Why would she exhibit flaccid paralysis first and then spastic paralysis?

There are three spinal cord tracts that most doc's are concerned with. The spinothalmic tract supplies pain and temperature sensation and crosses over to opposite side of the body every few segments. If you stab this tract at level T6 on the left or in the middle where the tract is crossing over to the right, you loose this sensation on that entire side of the body.
Damage in the spinal cord itself would be considered an upper motor neuron lesion which has the symptoms of increase reflexes and no fasiculaton of the muscle(flaccid). There is a difference between the symptoms immediate and late due to the initally swelling around the nerve decreasing and the further demylinization of the damaged nerve

teh nife cut sum nervs or sumthin now she cant move her leg cuz theres no conection
