Need Kinematic Gait Free Data

[Mahsa Salehi]

Hi,

I am PhD student, I need some free data on 7 joints of the human lower limbs. I have attached a file for the joints which I need data (both accelerometer and gyroscope data in 3D).
Would you please help me? How could I access to such a data?
I want to produce the position, velocity and acceleration from them in order to use for gait analysis.

Best,
Mahsa

Dear Mahsa,

This is definitely a FAQ on Biomch-L so as moderator I want to make sure we have some good answers posted here. I happen to know of a few sources of data, some of which may be suitable for you.

The book "Biomechanics and Motor Control of Human Movement" by David Winter (Amazon link) has an appendix with 2D gait data from a normal, though somewhat small, subject (56.7 kg). There are printed tables with joint angles and joint moments, but perhaps more important for you, raw marker coordinates with velocities and accelerations.

Files containing the data for the 2nd edition of the book (which is likely the same data) are available from the ISB website at http://isbweb.org/data/. I just noticed that the ZIP file is missing some files. I happened to have the complete ZIP file, it is attached to this post. If someone has converted this data to other formats (Matlab, Excel, C3D,...), please let us know by posting a reply.

That same page on the ISB website also has other data files. There is a nice set of 3D gait data files that were originally distributed with Kit Vaughan's book.

I also know of an Excel file by Chris Kirtley which contains various gait variables (no raw data). The spreadsheet includes regression models that Chris developed to scale the data to different subject mass, subject height, and gait speed.

If anyone else knows of other online gait data resources, please post!

Re: Need Kinematic Gait Free Data

Mahsa, I have an Excel spreadsheet of some of the Winter data. It has the trunk, hip, knee, and ankle angles and the GRF. I can email it to you if it is helpful, let me know (rosshm@gmail.com).

clinicalgaitanalysis.com provides "normative database"

The site http://www.clinicalgaitanalysis.com/ (also known as CGA) has plenty of data.

Hi Ross,

I'll send you an email. Thanks!

Hi,

Thanks for your help, It seems that the data is produced based on vision approach, yes?

Best,

Re: Need Kinematic Gait Free Data

Ross, thanks very much for sharing this. The Excel format will be much easier to use than the files I posted.

Any chance you can post your Excel file here? Biomch-L has some restrictions on attachments which may have stopped that. I just added an option to attach XLS files with a maximum size of 500 kB. Let me know if your file is larger.

Re: Need Kinematic Gait Free Data

Ton, I tried to attach it here but didn't seen an option for attaching files. There are buttons for links, images, and videos but they all just ask for a URL. Is there another way to attach files?

I could also just upload it somewhere and post the link.

Re: Need Kinematic Gait Free Data

Ross, yes, it is not obvious with the complex GUI of this forum system.

To attach a file, you need to click on "Reply" and then on "Go Advanced". Then you get many more options, including attachments. Let me know if the limit of 500 kB is a problem.

Here it is!

Re: Need Kinematic Gait Free Data

I would recommend the dataset that goes along with "Schulz B, Kimmel W. Can hip and knee kinematics be improved by eliminating thigh markers?. Clinical Biomechanics (2010) vol. 25 (7) pp. 687-692." as posted previously on this list. The only issue is that the data is in the proprietary Visual3D format so getting it out into a more generally usable format means you might need to find someone with the software and export what you want. It has 10 walking and 10 running trials of a single individual at 120Hz and is a complete 3D lower body kinematic analysis using largely cluster based reconstruction. What I'm looking for is an equivalent dataset with the upper limb as well! Ultimately providing the raw dataset like this is a really good way of getting a few more citations so I'm a little surprised it is so rare now that electronic supplementary data is accepted by almost all journals. Of course finding the data can be really tricky because you don't know it's there unless you read the paper carefully.

C-motion has a huge (138MB zipped) Visual3D CMO file from one of my recent studies that is available for free download here: http://www.c-motion.com/exchange/exchange.php
You can open it using their free CMO viewer, which is also available on that link.
This file has trials of walking, turning, running, jumping, and lunging for several simultaneously-recorded lower-body marker sets.

Re: Need Kinematic Gait Free Data

Hi Mahsa,

I just saw your posting requesting data. There is an Excel workbook with data that includes position, acceleration and velocity for the lower extremity joints (bilateral hip, knee and ankle) posted on our website. The data was generated from gait trials collected at UW-LaCrosse by John Willson and Tom Kernozek in 2010 and can be accessed here: http://www.innsport.com/related-prod...-data-set.aspx. The full UW-L data set includes 5 trials of bimodal gait data from each of 25 healthy young adults. The Excel file reports the ensemble average of all trials, normalized to 100 frames, and is reported in a format comparable to the Appendix of David Winter's text Biomechanics and Motor Control of Human Motion Data. You may also find the pdf report which is posted helpful- it uses the UWL data and includes the 8 phases of gait as defined in Gait Analysis by J. Perry and J. Burnfield

Please don’t hesitate to contact me with questions and good luck with your data analysis!
Best,
Meredith

Re: Need Kinematic Gait Free Data

Hi Mahsa,

While it's not accelerometer data, there is a repository of freely available walking simulations with joint kinematics on simtk.org: https://simtk.org/home/mspeedwalksims

These simulation results and associated models can be displayed and animated in OpenSim, which is also freely available: https://simtk.org/home/opensim (Note: the results files are tab delimited so can also be easily opened in Excel or Matlab).

The repository has 8 subjects at 4 walking speeds (fast, free, slow, x-slow), and the results were published in Journal of Biomechanics: Liu, M.Q., Anderson, F.C., Schwartz, M.H. and Delp, S.L., Muscle contributions to support and progression over a range of walking speeds, Journal of Biomechanics, Nov 2008, 41(15):3243-3252.

Best,
Sam
