My husband has had Parkinson's symptoms since 2003 and is now considered an Advanced Parkinson's patient. He needs a wheelchair for traveling any distance so we're wondering if a transport chair would be better that a standard wheelchair. Also, if we order through the internet does anyone know of a relaible company that accepts an emailed doctor's precription so we can be reimbursed by Medicare. Does Medicare designate specific wheelchairs be ordered? We'd appreciate any advice.
