glucosamine

is it useful for muscle spasms in paraplegics

[incitatus]

Its a case of inadequate studies, really. It may have some benefit, as may herbal treatments such as valerian. Do consult a GP or licensed herbalist before embarling on something new, though. Glucosamine is far more involved in connective tissue than musculature, but there have been anecdotal reports of improvements in spasm.
