England star Kevin Sinfield has raised more than £10m running for causes related to motor neurone disease, in memory of his late teammate Rob Burrow.

Conditions which are not currently on the medical exemption list include Parkinson's disease, cystic fibrosis and motor neurone disease.

He cited her support for cancer charities, people with motor neurone disease and domestic abuse victims.

These are two of seven different neurological conditions diagnosed among the claimants, including Motor Neurone Disease, Parkinson's and Alzheimer's.

Synchron is one such firm, which says its Stentrode device aimed at helping people with motor neurone disease requires a less invasive surgery to implant.
