For six years, I've suffered from a compacted spinal disc and unsuccessful corrective surgery. I finally found a neurology practice whose physical therapists have traced my walking difficulty to tight hamstrings due to nerve damage and atrophy. My neurologist says she understands that most insurance covers the purchase of a device called a Home Neuromuscular Electrical Stimulation Unit. I have not received a copy of Humana's EOC publication and the Humana website is no help to me in ordering one, nor does it answer my question about coverage for this device. Has anyone there been successful in this frustrating sort of search?
