Biomechanics Toolbox

The Biomechanics Toolbox is a resource with workbooks and software for basic biomechanical data processing.

[Biomechanics Toolbox @Biomech_Toolbox]

@isbs_conference Free for a limited period until the publication of the Biomechanics Toolbox Workbook!

Lots of threads around coding on here recently, and some valuable pointers! I'm looking forward to sharing a little on how and why I created EIS code school as a small part of my @isbs_conference talk later this week and continuing the conversation... 👩‍💻

[Biomechanics Toolbox @Biomech_Toolbox]

A lot of Signal Processing books ‘floated’ towards the top of the vertical bookcase! The one at the top not ready for publication yet but at least the cover design is done!

The main messages from my Inverse Dynamics & joint loading #SportsBiomLS lecture in 4 condensed slides!

We must stop using the terms 'net', 'resultant', 'intersegmental' or 'bone-on-bone' to differentiate joint reaction forces.

Looking forward to presenting the next #SportsBiomLS lecture Thursday 30 April, 11 am 🇬🇧, on Inverse Dynamics, assessment of musculoskeletal loading and related terminology & mechanical misconceptions. With thanks to @biomechstu @ISBSOFFICIAL & @Vicon

That’s it! 1 Day left. Submit your paper and be there or be square. And some more Liverpool trivia. Along from the ACC, the statue of John Hulley, one of the 3 founding fathers of the idea for the modern Olympics! PS we can’t guarantee this weather! @isbs_conference #ISBS2020

[V. Baltzopoulos @VBaltzopoulos]

The ACC Liverpool looking glorious in the sunshine by the magnificent Albert Dock on the waterfront during a lunchtime run today. If you want to be here in 6 months time submit your abstract now @isbs_conference @ISBSOFFICIAL. Deadline extended to 31/1! #ISBS2020

@luuleitner Thanks, Will do Christoph, submitted to JB but will publish preprint ASAP. Regards, Bill

Happy New Year 2020! Time to re-think inverse dynamics nomenclature & go back to real mechanical basics. Paper submitted for publication for a fresh look at inverse dynamics terms and joint loading. There are no different 'flavours' of joint forces. Only one joint reaction force!

The latest updated version 2.2 (4/9/19) of the fully functional demo of the #BiomechanicsToolbox can be downloaded from this site:
https://t.co/40qDwTZgXk
The installation file is a zip archive ~8MB. Download and extract the files and then read the installation instructions.

An excellent paper: https://t.co/l0k6xek8gt. An example of the two approaches using 'Actual Forces' & 'Resultant Moments' with the @Biomech_Toolbox. However, disagree with some suggestions as both are inverse dynamics and both are joint reaction forces. More in the Lab workbook!

[Biomechanics Toolbox @Biomech_Toolbox]

If you are attending the ECSS Congress in Prague and you want to see the @Biomech_Toolbox in action & discuss or suggest data processing examples to be included in the Laboratory Workbook then come to the ground floor Cafe Reunion during the lunch break 13:00-13:30 on Friday 5/7

For more basic Inverse Dynamics classes with the @Biomech_Toolbox, students can be given FBD files 'prepared earlier' and they can Load FDBs at different positions to focus on effects of muscle mechanics on loading. Note the muscle-tibia angle at full ext and 90 deg flexion here.

[Biomechanics Toolbox @Biomech_Toolbox]

Another example with the Inverse Dynamics tool in the @Biomech_Toolbox for demonstrating joint and ligament loading through compressive and shear joint force calculations during a simulated hamstrings curl exercise

[Biomechanics Toolbox @Biomech_Toolbox]

In Inverse Dynamics classes with the @Biomech_Toolbox, students can be given joint modelling data for constructing FBDs to examine effects of muscle mechanics (mom. arms, lines of action) on joint loading by calculating comp & shear forces at different positions (0 & 60 deg here)

[Biomechanics Toolbox @Biomech_Toolbox]

The Optimisation tool in the @Biomech_Toolbox can also be used to simply examine the effects of moment arms and coefficients linked to muscle properties (e.g. Max Force, PCSA etc) on the distribution of the joint moment to the active muscles using static non-linear optimisation

[Biomechanics Toolbox @Biomech_Toolbox]

Indeterminate systems in Inverse Dynamics & Optimisation with the @Biomech_Toolbox : if there are >1 unknown forces in the FBD (Force label exists but Magnitude=0) then you must use Reduction or Optimisation to solve the indeterminate system since no of unknowns>no of equations.

[Biomechanics Toolbox @Biomech_Toolbox]

In the Inverse Dynamics module of the @Biomech_Toolbox, the force vectors are displayed with the same length by default, but after Calculation, you can display the forces to scale for students to appreciate magnitude differences visually. Just change the Scale value in Options.
