GaitSmart Rehabilitation Exercise Programme for Gait and Mobility Issues: A NICE Medical Technologies Guidance

GaitSmart (Dynamic Metrics Ltd) is a class I CE-marked sensor-based digital technology designed to measure lower limb movement via sensors placed on the body. GaitSmart aims to identify any problems with gait, and provide a personalised rehabilitation programme via the integrated vGym app. The company identified people referred for knee or hip replacement and people at risk of falling as potentially being able to benefit from GaitSmart. The clinical evidence identified was limited in its applicability to the scope of the assessment, and there was large variability in the comparators used in these studies and in the current care pathways, especially for people at risk of falls. There is some limited evidence that patients like the report generated by the technology and found it helpful in understanding their condition. Clinical experts thought GaitSmart had the potential to improve outcomes for patients and could be used in the community setting by a range of healthcare professionals. Economic modelling over a 1-year time horizon from a UK National Health Service (NHS) perspective for the falls model and a 17-week horizon for the rehabilitation model indicate that GaitSmart is cost saving; however, this is dependent on the model of standard care. Where GaitSmart is delivered by trained healthcare assistants, it would lead to a reduction in staff time costs compared to most alternative standard care options. Uncertainty is greater in the falls model given the high variability in standard care. In April 2024, the National Institute for Health and Care Excellence recommended that GaitSmart can be used to treat gait and mobility issues in adults at risk of falls, while more evidence is gathered. For adults having hip or knee replacements, access to GaitSmart should be via the company, research or non-core NHS funding, with appropriate management of any risks.
