    DESCRIPTION
    Individuals post-stroke often experience abnormal timing and magnitude of muscle activation as well as altered muscle force generating capacity. When generating musculoskeletal models of post-stroke individuals, it is necessary to determine whether the inclusion of subject-specific properties will have a meaningful influence on model results when compared to generic muscle properties. In this webinar, we will discuss our use of experimental and imaging data to guide the development of subject-specific simulations. In particular, we will describe our processes for evaluating the maximum isometric force and volitional activation of major muscle groups of the lower limb in stroke survivors and our process of integrating this data into OpenSim models. We have found that inclusion of subject-specific muscle data when modeling post-stroke gait results in appreciable changes in the model predicted force and activation. Importantly, the observed changes in model results agree with commonly observed compensation patterns in stroke survivors, including increased hip and knee flexor activity and decreased plantar flexor and dorsiflexor activity. Ultimately we hope to use the inclusion of subject-specific data into musculoskeletal models to improve the relevance of our modeling results and enhance the design and outcomes of future rehabilitation.

    Participation is free, but you must register in advance. We also ask that you join the webinar 5 minutes early to orient yourself to the webinar interface.
