The BME 600 seminar series is an opportunity to practice the presentation skills BME graduate students will need for the defense of their thesis, or for presentation of their research at scientific meetings. It is also a forum where you will learn to critically review the scientific and presentation skills of your peers.

Presentation Topic: "Validation of Fitbit-like device for Measuring Propulsion Metrics for Manual Wheelchair Users"

Presenter: John Christy Johnson, Dept. of Biomedical Engineering


The significant stresses involved in manual wheelchair propulsion can place manual wheelchair users (MWUs) at a significant risk of developing upper extremity overexertion injuries.1,2 Extracting propulsion metrics such as propulsion force using portable sensors provide valuable information for wheelchair users4,5, especially to assist with over-use injury prevention and navigation in challenging built environments.

The SMARTWheel (Three Rivers Holdings, LLC, Mesa, AZ) is considered the "gold standard" in tracking these metrics for MWUs.6,7 It relies on replacing a wheel of the MWU's wheelchair with wheel which senses torque applied specifically to the pushrim. Unfortunately, the SMARTWheel is expensive ($20,000 retail price), much heavier that a regular wheelchair wheel, and not ergonomically attractive.

Our lab has developed sensor (Redliner), which is much cheaper (~$100 components alone), lightweight, and sleeker that attaches to the spokes of a wheel. Redliner consists of a control board, novel firmware, with two accelerometers and a module, which reads and transmits data. The dual accelerometer design eliminates spurious noise by subtracting the common mode. Here, I compared angular acceleration and force profiles to determine if Redliner is comparable to SMARTWheel.
