1. Article Review: Briem, K., & Snyder-Mackler, L., "Proximal Gait Adaptations in Medial Knee OA", Journal of Orthopaedic Research, Published Online DOI 10.1002/jor.20718, 2008.
2. Round Table Discussion: Research Developments
Rebecca/Stacey
- Force plate and pressure mat do not match
- Pressure mat not always overestimating as they would expect – weird.
- They are trying to understand just how the pressure mat is measured so that the correct pressures can be obtained. Right now they are +/- 10%.
- Implant was redigitized and Rebecca thinks it matches pretty well with CAD now
- Stacey is looking at sensitivity to the choice of the original axes – is it off by 2-3 deg?
- Next step is to recalculate the euler angles from old data with the new various axes.
Nicole
- Has subjects today & Tuesday à controls
- Is keeping her fingers crossed with her computer issues
- The wine cellar is too cold which is a little disconcerting
- She has a new TAship
Heather
- Formatting the presentation of her work
- How does taking off the dynamic offset change the significance of the trunk lean peaks?
o She wants to look into this more to understand this alternative to static calibration which may be flawed.
- Other problem: GT markers are missing very often so they are not a good choice to rely on, so any method of calculating trunk lean that relies on the GT markers is automatically unusable.
- Heather will proceed with the BSIS points because most data exists for those
o There are 4 methods in total for calculating trunk lean
- Hopefully she will present to us next week
Scott
- The gimbal looks like it is working, however the locking mechanism is awkward and not the best.
o He may or may not analyze the gimbal data that he collected
- Repeated measures ANOVA is working in MATLAB
o Also wrote a post-hoc tester as part of this
- Ran his data without outliers and the story was more or less unchanged
o Is his data set pre-cleaned? Maybe?
- Talking to Scott Selby about the jump from inverse dynamics to forward dynamics and how people in various places are dealing with it.
Simon
- Continuing to read about ligament properties and gastroc dysfunction.
- Quote for ADAMS: $7500 for 5 licenses for 1 year
- Working on NSERC & OGS applications
o Advice from JAM: avoid biomechanics jargon when doing application, but since it will be read my mechanical engineers, gear it towards the base mech eng engineer.
- Needs someone to switch chairs for Oct 10, Nicole & Simon will work it out.
3. Kevin’s announcements
- Kevin has no announcements this week
4. Other Announcements
- This is Rebecca’s last week at JAM. Her last day is Tuesday. Goodbye lunch will be Monday. Best of luck Rebecca!
