Researchers have developed a new way of designing and manufacturing bespoke prosthetic liners, which could help more amputees walk again.
The team at the University of Bath are inviting military personnel to come forward to try out the new technology.
It is hoped the development could be used in the NHS, saving the health service money and giving patients a better chance of recovery.
John Roberts, one of the amputees who has been trialling the new prosthetic liners, said he would wear up to six layers of socks to avoid issues with rubbing and blood blisters.
He said he is "very impressed with the new liner":
"I can put on my leg quickly in an emergency."
To test the new liner, researchers inserted pressure sensors inside the socket to check the fit of the liner and used motion capture technology to monitor Mr Roberts’ walking.
Dr Elena Seminati, Lecturer in Clinical Biomechanics at the University, said the new liner "reduces the pressure on the stump significantly, reducing the risk of skin damage and making it more comfortable to walk".
The researchers are continuing to test and develop this approach and hope to help ex-service personnel who have a lower-limb amputation.
