Encompassing cognitive personalised behavioural therapy

Re-thinking knee recovery

We worked with a Sydney based incubator to create an app that assists in gathering knee flexion/extension data from sensors in a way the practitioners can access, provide accompanying information to patients recovering from total knee replacements. We used a research first approach, then dived into Rapid XP workshops.

problems & pain points

After conducting a series of interviews and workshops. We identified various pain points from the patient, physio and surgeon. 3 personas and user journies were defined during a patients pre and post knee rehabilitation process. These were important in addressing the key fundamental problems that were brought forward into the RapidXP sessions.

“Developing healthcare software differs from traditional enterprise software we build at Servian. It demands a deep understanding of not just the technology itself, but regulatory and interoperability requirements, and most importantly the needs of the user.


By taking a user-centred approach we are interested in the everyday interactions of a patient rather than an idealised account of a user flow”

In the workshops, we tackled the problem from a patient first approach. From the research, it was clear that developing a feedback loop between the clinician and the patient was vital, so we engrained this into the user story.

As a patient, I want to be given feedback on how my pre and post rehabilitation progress is going.

outcomes from rapid xp

A successful solution would have to not revolutionise the current patient workflow, subtly adding to the workflow would mean adoption from both patients and clinicians. It was clear from the workshops that there would be 3 products:

recovery consultation

release two

Release two integrates Bluetooth enabled sensors that are strapped to the knee and leg to allow for continuous activity monitoring.

The collation and analysis of the range of measurements collected provide valuable insights into a range of variables that improves treatment outcomes.

A 3 month trial at a Sydney private hospital showed that regular use of this non-invasive wearable for 6 weeks after surgery proved to optimise “active” pain recovery management and function identification of distressing and disabling psychological factors.
