An app that uses artificial intelligence (AI) to provide physiotherapy for people with back pain has cut treatment waiting times by 55%, according to an NHS trial.

NHS patients in Cambridgeshire and Peterborough were the first in England to take part in a three-month trial with Cambridgeshire Community Services NHS Trust.

The program uses AI to triage, treat and discharge patients and the trust said it allowed about 2,500 hours of clinician time to be diverted to more complex cases,

Jayne Davies, the trust's clinical lead for musculoskeletal (MSK) services, said: "A third of our workload is lower back pain and demand outstrips capacity.

"If rolled out thoughtfully, this could be a game-changer for patients and the NHS.
