Parkinson's UK has called for the government to reverse its decision to remove the mobility component of Disability Living Allowance (DLA) for those who live in residential care.
The move, which is estimated to affected 80,000 people, springs from the coalition's argument that the mobility component of the DLA is an overlap of public funds.
However, Parkinson's UK argues that none of the national service providers surveyed receive any funding from local authorities towards personal mobility costs.
In addition, the survey also found that more than half of residential care users said they gave either the majority of all of their DLA mobility component to their care home.
Anjuli Veall, social policy and campaigns manager at Parkinson's UK, said: "We hope that our continued support of this report will help urge the Government to have a rethink on these proposals that have now been proven to be unjustified and unfair on the most vulnerable people in society."
