Wearable technology is all the rage as people everywhere recognize the value of quantifying the daily effort they put into being active (or lack thereof…). The convenience of wirelessly transmitting activity data onto a mobile device in an instant is an innovation that can be used anywhere on the go; and now, in the clinic. Thanks to scientists in Denmark, not only can you trick your wrist out with the latest high-tech trackers, but you can also suit your elastic resistance bands up and finally answer the question, “are my patients actually doing their exercises at home?”

Track resistance band data with BandCizer

The Bandcizer is the first sensor that can be placed directly on elastic resistance bands. With this device that’s slightly larger than a quarter, clinicians and patients can wirelessly measure the tension of the band and quantify elastic resistance exercise, both in the clinic and in home exercise programs. The Bandcizer is specifically calibrated to TheraBand resistance bands, but it’s uses don’t stop there. The tracker also measures steps, distance, velocity, repetitions, intensity and motion.

According to Healthcare Denmark, the Bandcizer provides a wide variety of highly valuable clinical data such as live bio-feedback, time under tension and compliance. As for the interface, users can:

  • Design an in-clinic or home exercise program
  • Schedule the trainings on a calendar
  • Receive live instruction and feedback during exercise
  • Analyze data after the workout is complete

How the Bandcizer will amplify your clinical efficacy

When done with a trustworthy tools like the Bandcizer, quantifying elastic resistance training can be a game changer in your clinic. “Clinicians and researchers can accurately assess exercise dosage and adherence, as well as the quality of exercise,” said Phil Page PhD, PT, ATC, CSCS, FACSM (2016). “A relatively novel concept in quantifying exercise dosage is time under tension.”

Time under tension, or how long a muscle contracts during concentric, eccentric, and isometric phases, provides a more authentic measure of dosage because it acknowledges the speed of exercise rather than just the number of repetitions performed. The Bandcizer combines these two factors so you can make sure your patients are getting the quality and quantity of training they need.

Improve home exercise program compliance

After patients are given their training recommendations, however, it’s not always easy to tell if they’re actually completing their exercises. Not anymore! Slapping a Bandcizer on a band has been proven to accurately measure adherence of home exercise programs of the shoulder (Rathleff et al. 2014), hip and knee (Rathleff et al. 2015).

Prescribe the right amount of resistance

As for the quality of resistance, a cornerstone in exercise prescription is ensuring that patients are working hard, but not too hard. Up until now, the basis of tension recommendations was strategic guessing or patient feedback; but with the Bandcizer, clinicians can receive actual data of how hard patients are working.

“Michael Rathleff PhD and his colleagues (2016) recently found that the Bandcizer was feasible for measuring the quality and dosage of home exercises for adolescents with knee pain. Using the Bandcizer, they found that only 5% of patients performed the appropriate amount of time under tension, noting that 90% did not receive the prescribed exercise dosage” (Page 2016).

Make sure patients are moving correctly

Great, we have measurements of the patients actually completing their exercises with the right amount of tension. Now how do we know that they’re doing them right? Luckily, the Bandcizer has a 3D gyroscope that measures angular rotation: a.k.a., real-time data on the quality of individual exercise movements! For example, one researcher used the Bandcizer to discover that a majority of the subjects did not correctly perform their shoulder exercises after two weeks (Faber M et al. 2015). Now, clinicians can make sure they reinforce proper movement patterns with patients to make sure they’re properly meeting their goals.
