It varies so much depending on the activity of the disease, how many joints are affected, the general condition of the patient, and so on and so forth.
Normally during active inflammatory stage the emphasis is on prevention of deformities by resting splints and positioning plus gentle ROM exercises. (Cold therapy may be helpful during this stage)
As the inflammation dies down gentle stretches and graded strengthening exercises are advised. Heat might now be more comfortable to ease stiff joints and muscles.
Pool therapy is often lovely for these patients as the warmth eases moevemnt and water can be used to assist or resist movements.
