Increase chest expansion with intellectual disability

Any suggestions for techniques to increase breathing capacity and chest expansion in a person with an intellectual disability and undiagnosed physical disability?
Any help would be much appreciated
Thanks

I would look for games that include blowing, e.g. maybe blowing bubbles, blowing up ballons, maybe the use of a paediatric (more fun styled) incentive spirometer.

Thanks very much for your help:)
