An AI-powered physiotherapy clinic has expanded across 11 NHS regions to provide patients with same-day appointments for back pain via a smartphone app.

Flok Health has been rolled out to more than more than 2.4 million patients across 11 NHS areas including Cambridgeshire, Peterborough, Airedale, South Yorkshire (Doncaster, Barnsley, Rotherham, Sheffield), Northamptonshire, and three London boroughs.

In its first large-scale pilot in England last year, the clinic more than halved waiting lists for back pain and reduced waiting times for all musculoskeletal (MSK) conditions by 44% in less than 10 weeks.

Finn Stevenson, co-founder and chief executive at Flok Health, said: “It’s been incredibly exciting to see such a positive response to our technology from NHS trusts and commissioners across the UK.

“We’ve long believed that the right technology could completely transform how musculoskeletal care is delivered in the UK, transforming the lives of millions of patients, and delivering significant cost savings for the NHS.

“We are currently the only digital physiotherapy provider in the UK with the necessary regulatory approvals to immediately deliver on NHS England’s goal of deploying digital solutions at pace to meet demand for MSK services.

“Our goal is to continue to deliver gold-standard MSK care at population scale, enabling patients to access care immediately, whilst freeing up clinical capacity for patients who want or need to see a clinician face-to-face.”

The AI service manages patients on behalf of the NHS from initial presentation and assessment through to treatment delivery and discharge, and records all interactions and outcomes on the patient’s electronic health record.

Flok Health’s expansion follows the publication of  NHS England’s medium term planning framework in October 2025, which provided guidance to NHS trusts to consider where digital solutions with appropriate regulatory approval could be deployed at pace.

A few weeks before the guidance was published, Flok Health secured Class IIa Medical Device approval under EU regulations, meaning that it can carry out diagnostic decisions without human supervision.

Matthew Winn, chief executive at Cambridge Community Services NHS Trust and Norfolk Community Health and Care NHS Trust, said: “It’s been fantastic to see the impact the Flok Health pilot has had for our patients and staff.

“Thousands more people are getting faster access to expert physiotherapy support, waiting lists have been cut by more than half and our clinical teams have more time to focus on those with complex needs.

“It’s exciting to see how innovation like this, introduced safely and thoughtfully can truly transform the way we deliver care.

“We’re now looking forward to rolling Flok out more widely across the trust so even more people can benefit from quicker, high-quality MSK support closer to home.”

According to Flok Health’s data, patients receiving treatment from the solution have seen an average improvement in MSK-HQ score of 6.16 points, with anything above 5 considered statistically and clinically significant.
