kinematic and kinetic analysis

[Maryam Hajizadeh]

Hi,


I am MSc student in biomechanical engineering. I want to do kinematic and kinetic analysis on ACL deficient people during ascending stairs. I want to write some MATLAB codes to do these analysis.

I have studied the book "dynamics of human gait" by Vaughan. In chapter 3 and appendix 2 of this book, some algorithms and mathematical equations has been brought to do a complete analysis procedure. I wanted to know whether these algorithms are used by other people who do gait analysis or not.

If there are different algorithms and equations, would you please introduce me any other references for this issue?


Regards,
Maryam

Re: kinematic and kinetic analysis

I am unfamiliar with the contents of the mentioned text.

In terms of knee coordinate systems, the Grood and Suntay system (J biomech Eng 105:2, 136-44 1983) is a standard.

Coordinate transforms are explained nicely by Zatsiorsky in 'Kinematics of human motion' and Winter's 'Biomechanics and motor control of human movement' has nice examples of implementing such principles.

Kinetics are explained in Zatsiorky's 'Kinetics of human motion' and in Winter's book.

If you'll be using a marker setup with more than 3 markers, Challis 1995 J Biomech, 28:6, 733-7 is a necessary read.

Re: kinematic and kinetic analysis

It would help the members of this forum if you tell us what method you will incorporate to study the kinetic and kinematic parameters. Is it going to be marker method or markerless?
"Human Motion analysis: A review" by J.K. Agarwal and Q.Cai is a good start to review the popular computer vision techniques employed for human motion analysis.
"Vision-based human motion analysis: An Overview" by Ronald Poppe entails relatively newer methods and algorithms than the earlier literature.
This should get you started. You can always track the references quoted in these papers in case you need finer details.

Thank you for your reply.
I would use marker method. I would use Helen Hayes marker placement method.

You should also refer to OpenSIM. See publications http://simtk-confluence.stanford.edu...=1319839092137, http://simtk-confluence.stanford.edu...=1319839162970.

Re: kinematic and kinetic analysis

Chances are there are different ways one could arrive at inverse kinematics from the HH marker set, but I would suggest searching for published work of Kadeba, Ramakrishan and others whom I believe were at Helen Hayes and published a number of papers on kinematics of gait with the HH marker set. It's been a while since I've read those papers (late 80's?), but it might be a place to start. Once you figure out the kinematics and can get joint centers, then you can use any number of approaches to solve for inverse dynamics (as mentioned above).
