Well for each pathology there will be clinical features. To be honest they will probably ask you about stroke so if you take stroke for example, they will have hypertonus (spasticity) in elbow wrist and hand and some at the shoulder. That side will also be weak. In the lower limb, there will be dense hemiplegia possibly and therefore it will be weak. Then they might have increased plantarflexor and inverter tone. So you will do stretches to get them out of the patterns and positioning to reduce tone. You will do active assisted exercises progressing to active exercises etc to get muscle recruitment and strengthening. A long winded explanation but hope you see where I'm going. Good luck in the exam
