As a quad, one of the main problems for me is balance or lack of it.
Being paralyzed from above my chest means I have no active core muscles and thus little balance. Sitting upright in a chair for 10 hours plus can become very tiring and result in alot of strain on my neck muscles.
I have tried many orthapedic waste binders but the Velcro material they are constructed from has proved painful and irritable on my skin. These waste trainers I found online help with balance and also with low blood pressure I have as a result of my c6 spinal cord injury. Also it helps that they are girlie and visually less clinical than hospital ones.
I found them on amazon or google waste trainers. I pay 55euro approximately but they are definitely worth it! I wear a sizd small and I am a size 8/10.
