I do not heard of any alternative medicine that might be useful of, but literature states the benefits of physical and rehabilitation therapy. Massage might ease the painful spasms.
Also, for 'common' spasm warm is usually helpful. My mom used the hairdryer to warm her leg muscles when she had a painful spasm.
I sincerely hope you could find something useful info for your relative.
