Background
EnMovi is a spin-out company from OrthoSensor and McLaren Applied, formed to advance MotionSense wearable technology.
The venture brought together OrthoSensor’s experience in sensor-assisted orthopedics and McLaren Applied’s expertise in data, software, and advanced engineering. MotionSense had the potential to give patients greater confidence during recovery while providing care teams with objective movement data. To realize that potential, EnMovi needed a mobile experience that made complex information easy to understand and use at home. That is where Cruxlab came in.
We reached out to them [Cruxlab] again because they were very quick and agile and because they were available to take on the work.
Challenge
EnMovi faced a tight deadline ahead of a major orthopedic tradeshow and upcoming clinical testing. Missing it meant losing a key opportunity to showcase the technology, gather feedback, and maintain momentum.
Immediate objective: functional application demonstrating the MotionSense capability on time for the event.
The app also had to work for adults aged 50–65 with varying levels of tech confidence, often shortly after surgery when pain and limited mobility could make simple tasks difficult.
With clinician-guided activities moving into the home, sensor setup, calibration, exercise selection, and movement tracking had to be exceptionally simple and clear.
Our approach & solution
We started with a four-week [discovery phase] to understand MotionSense beyond the interface — its users, clinical context, wearable sensors, and recovery process. Working directly with development hardware helped our designers and engineers see how the technology behaved in real-world conditions and shape the experience around it.
A major focus was turning complex sensor-based exercises into a clear at-home experience. Our work included:
The result helped patients understand both what to do and how well they were doing it, without relying on a clinician being physically present.
The team took great ownership of the project and exhibited an in-depth understanding of how the technology should interact with the wearable physical therapy device.
We worked in focused sprints with close collaboration between our UX, engineering, and EnMovi’s clinical and technical teams. Strong [product management] helped us identify gaps, improve the experience beyond individual requirements, and begin rolling out the first versions within two weeks.
Cruxlab delivered a full-featured application connecting patients with the MotionSense wearable throughout knee replacement recovery. The experience combined device connectivity and calibration with movement visualization, exercise guidance, data collection, and patient feedback.
The application was later used with the wearable device in a clinical study, where patient feedback was highly positive. Following a series of successful milestones, EnMovi was acquired by Stryker, bringing MotionSense and its supporting digital platform into Stryker’s broader orthopedic ecosystem.
“We were really pleased with Cruxlab’s services because they took us a step further in understanding the system. They performed excellently on the project, delivering on time and within budget. The way they took ownership of the project really stood out to us. ”
