Other possibilities like upper motor neuron lesions or b 12 deficiency or neuromuscular junction problems may present like this. Until examination is done it is difficult to say what it is. Do regular physiotherapy and good nutritional support she may recover. Don't worry, but please consult with your neurophysician he will examine and treat you accordingly. Take care. Hope I have answered your question. Let me know if I can assist you further.  </s>
