Impact of exercise access on physio outcomes post knee replacement
Research type
Research Study
Full title
A feasibility study to determine the effect of an artificial intelligence (AI) based motion tracking exercise programme (Kemtai) on amount of physiotherapy contact and length of hospital stay after knee arthroplasty compared with exercise as usual.

Research summary
Patients in need of a new knee joint are given exercises to do. It is known that people who are given exercises for their health do not always do them as advised. Exercises are more likely to be done if they are fun, if people know what to do and can see progress, and if they know that someone is able to check what they are doing.
Kemtai is a web based exercise program which helps people to move joints fully and strengthen muscle. It shows how to do each exercise and tells the person how to do it right if they are not doing so. The person gets a score to show how well they are doing the exercises, which their physio can log on and see. If the score is getting higher this shows they are making progress.
We want to find out if people who exercise using Kemtai leave hospital sooner and need less physio after having a new knee joint than those whose exercises are on a paper sheet or e-mail as usual. This study will also tell us how much people exercise before surgery. For the study, people who need a new knee are referred to a joint school. Their physio will tell them about the Kemtai programme and study. Those who want to take part will be able to chose to either have a list of exercises (usual care) or the Kemtai programme. The groups will be compared on (a)the number of times they see a physio in the six weeks after surgery; (b) the number of days in hospital after surgery; (c) amount of change in pain and function (Oxford knee score) d) quality of life (EQ-5D-5L) and e) amount of exercise done.
