Please note that the following blog is based on a research study and is not medical advice.
Our team decided to take a deep dive into the value of Range of Motion data for a patient recovering from knee operations. Primarily, this will included Total Knee Replacements but can also extend out to other minor procedures. We believe that data surrounding one’s injury can be a crucial indicator of progress, but only if it is used at the right time and with the right understanding of what to do with it. Now we know as patients, we are not adequately qualified to self-prescribe, however, we can make a small effort to understand our data.
In fact, this is not new, we already do it in tracking our weight, heart rate and nowadays, our sleep too!
In 2016, a group of researchers out of the Netherlands, assessed the data of 137 patients recovering from Total Knee Replacement by assessing their Range of Motion pre and post operation. Following the 8 weeks, they segmented the patients into two categories; ones that achieved a sufficient ROM (≥ 90°) in flexion, and ones that did not, the insufficient group (< 90°).
Although knee recovery is non-linear and will likely differ for most patients, the researchers found that the ROM data of Knee Flexion and Extension from Day 1 through to Week 4, would have predicted the insufficient group’s results. This is because there was a drastic increase in results during that time. Interestingly they also found a limited improvement from week 4 to 8 but in some cases, a worsening of flexion.
Using our Bodii Flex along with the mobile app, patients are able to accurately measure their Knee Flexion and Extension within seconds, while being able to view the trend data. By sharing this back with each one’s physician, we can improve the feedback loop and accelerate the decision making time when it’s needed most! We believe this is step one towards achieving stronger cohesiveness between a physician and a patient.
