CNB Workshop 2020
‘Integrative Muscle Modelling for Neuromechanics’
A one-day satellite workshop to be held Monday, August 3, 2020, on the Georgia Tech campus, the day before ASB2020 (https://asb2020.gatech.edu/).
Location: Georgia Tech Campus, Kendeda Building (exact location to be confirmed)
It remains a fundamental challenge in muscle physiology to develop predictive models that accurately capture muscle’s response to rapid, transient and perturbed dynamics. Models used in current musculoskeletal simulations typically assume ‘Hill-type’ properties with quasi-static force-length and force-velocity characteristics. Such models do not adequately account for well-established history dependent properties. Hill-type muscle models perform best for the conditions under which the Hill-type characteristics are measured— maximally stimulated isometric or isotonic contractions. Relatively few natural movements involve such constrained muscle dynamics.
This workshop aims to bring together scientists with shared interests in muscle physiology, muscle modelling and comparison of model predictions to experimental datasets. The workshop will be a small, interactive, single-track event of 50-75 participants in total. Activities will include presentations and interactive brainstorming sessions to develop plans for future CNB-led initiatives to facilitate open sharing of muscle datasets, models and simulation tools.
Focus topics for discussion and brainstorming at the workshop
1) Identifying and discussing critical gaps in knowledge.
2) Encouraging collaborative partnerships to bridge these gaps.
3) Developing best practice recommendations for validation of models against datasets.
4) Brainstorming plans for an open web resource to share curated datasets, models and simulation tools.
The workshop brainstorming sessions will include facilitators to moderate discussion of specific focus topics, and to document ideas as they develop. The resulting documents will be collated and circulated to participants for feedback afterward.
As an outcome, we aim to develop a co-authored perspective article on the state of the field, ongoing challenges and best practice recommendations for standardized reporting of muscle data, and model benchmarking against curated datasets.
The Integrative Muscle Modelling for Neuromechanics workshop, organized by the Comparative Neuromuscular Biomechanics working group (https://sites.psu.edu/cnbgroup/about/) will bring to bring together scientists with shared interests in muscle physiology and muscle modelling across organizational scales from molecules to behavior.

SARS-CoV-2/COVID-19 contingency plans
We recognize the uncertainty of the rapidly changing situation surrounding the SARS-CoV-2/COVID-19 outbreak. It is too early to know the potential impact on travel in August. We will continue to monitor the situation closely and will update participants of any change in plans as needed. Our plans will be tightly coupled to any changes to ASB2020, which currently remains scheduled to move forward from August 4-7th, with an extended abstract deadline of April 3rd. In the event that ASB2020 is cancelled we will likely run a virtual workshop to conduct the proposed activities.
To increase flexibility for attendees in the face of ongoing coronavirus concerns, we will arrange for virtual attendance via Zoom (or similar) for individuals who wish to participate but are not able to risk travel even if the in-person event proceeds as planned.
