Q: My sister has a stroke and has done many therapies to get better. Now she has noticed that her posture is suffering as she finds herself hunching over and not keeping her back straight. I got this back brace support for her and it fits her just right. She has been wearing it for at least 3 hours each day the last two weeks and already feels an improvement. She puts it on in the morning and wears it til lunch. I have noticed her keeping her shoulders back more often and being more aware of her posture so it is helping.
A:
positive
