After something as devastating as a stroke it is vitally important that you get therapy (physical,occupational,and or speech) as soon as possible. Get as much therapy as your insurance will allow. Then learn from your therapists the specific exercises that you can do at home on your own or with your caregiver, spouse, etc.

 I am not a doctor or a therapist nor do I play one on the internet.
So before you do anything on your own consult first with your doctor and therapist.
Eventually though the insurance will probably stop funding your therapy but you must keep doing your therapy if you wish to continue to improve.

The internet is your friend. Do extensive research about your specific affliction and learn as much as you can and continue to get updates as new advancements and treatments are always being found.

Remember" that if you don't use it you will lose it". Use your weakened limbs(and brain) as much as practical without causing harm. Always be safe. Don't over extend yourself.

Design a practical plan with your doctor, therapist, caregiver or family members and never give up.

Strive for little improvements every day and you will amaze yourself.

Even years after a severe stroke many survivors continue to see improvements but you can really help your cause by your own diligent work and positive can do attitude.
