I like how easy it is to use and customize the models within the software making it ideal for beginner and experienced users Review collected by and hosted on G2.com. What do you dislike about OpenSim? I dont like how specific the file formats need to be in order to make the software be able to run the analysis Review collected by and hosted on G2.com. Recommendations to others considering OpenSim: The great thing about the software being open source is that help for it too can easily be found online either through the forums or others sharing their work online. Review collected by and hosted on G2.com. What problems is OpenSim solving and how is that benefiting you? I am using the software to run motion analysis comparing how locking and unlocking joints of the lower extremities affects joint kinetics and joint contact forces. The software has helped in realizing how small changes affect the rest of the system. Review collected by and hosted on G2.com.

MG Manideep G. PHD Student Small-Business (50 or fewer emp.) 12/16/2020 "Biomechanics of Standing Wheelchair & Gait analysis." 5/5 What do you like best about OpenSim? Visualisation of various muscle activations, while a person is standing in a wheelchair. The tug of war competition to get used to the interface and to know all the controls. I attended a very useful webinar that explains the principles behind each operation. Being an open Source product, It is helpful to know about what others are using the software for. This not only keeps you updated with research trends but also gives the opportunity to know people who are working in similar research areas. Review collected by and hosted on G2.com. What do you dislike about OpenSim? I started using Opensim while it is transiting from 3.0 to 4.0. It took me a while to get accustomed to the newer version. I would recommend not to release a newer version until it is completely upgraded. This avoids a lot of confusion among users. Review collected by and hosted on G2.com. Recommendations to others considering OpenSim: This OpenSim software is easy to learn, well documented to learn quickly. Review collected by and hosted on G2.com. What problems is OpenSim solving and how is that benefiting you? I used it to solve inverse kinematic problems. I got the range of motion of various joints using IK operation from data collected in our lab. It reduced my computational time and is open-source, I could easily change the generic models according to my requirement. I used it to develop a module in MATLAB using OpenSim. This takes kinematic data from a novel sensor to visualise the human movement. I also used it as a tool to complete my course project regarding Gait Analysis.

I have used OpenSim for many applications. I was successfully able to integrate the real-time motion with open sim models. That is pretty cool and it helped many people to detect some unusual behaviors. Apart from that, I have used cerebral palsy children's model, tendon transfer surgery simulation, and etc as teaching materials. I am still using it for my research purposes. Review collected by and hosted on G2.com. What do you dislike about OpenSim? I didn't quite capture downgrades or dislikes yet but I would like to suggest to implement more models. It will help the community to research more aspects of biomechanics. Review collected by and hosted on G2.com. What problems is OpenSim solving and how is that benefiting you? I used it to identify different walking patterns of humans in real-time data. Results are affected to change those incorrect patterns with easy validation proof. I am using models as teaching materials for biomedical students as it helped to investigate more biomechanical movements. Demonstrations with these modules are a lot simpler than explaining. Explaining the procedure in tendon transfer surgery is more helpful with the models. The cerebral palsy children's model is helpful to investigate more on that issue while simulating with real-time data. More biomedical researches can be done through this platform.

Senior Research Scientist Small-Business (50 or fewer emp.) 12/12/2020 "Modeling, Evaluation, and Control Optimization of Exoskeletons with OpenSim" 5/5 What do you like best about OpenSim? Intuitive musculoskeletal models for running simulations to evaluate the effectiveness of the wearable devices on the walking. It is useful to optimize the design parameters and control strategies of the exoskeleton by analyzing metrics related to metabolic cost and muscle activity. This is the best tool available to run simulations before running real world experiments. Review collected by and hosted on G2.com. What do you dislike about OpenSim? It is difficult to integrate custom built objects for new models with already existing musculoskeletal models in the Opensim. For instance, a custom built object for muscle activation is difficult to integrate. However, currently efforts are put to improve this feature. Review collected by and hosted on G2.com. What problems is OpenSim solving and how is that benefiting you? Running simulations to evaluate the effectiveness of the wearable knee assistive device on the reduction of metabolic cost and knee muscle activity. These simulations helped to gain insights regarding optimizing the design parameters and control strategies of the knee exoskeleton to improve assistance performance.

The most helpful side of OpenSim is its open-source nature. On one hand, this provides a suitable environment for users of the program who have limited experience with coding and software engineering to be able to run simulations using their experimental data, on the other hand, it provides a platform for software developers and advanced users with a variety of capabilities (i.e. physics-based modeling, optimization and customized dynamic simulations) . The other advantage of the OpenSim is the website and the forum which provides access to all the projects developed by other users (mostly open source) and a platform enabling communication for the issues or challenges regarding to individual project. Review collected by and hosted on G2.com. What do you dislike about OpenSim? The main downside is the steep learning curve between transitioning from a user to an advanced user/project developer position. It requires a considerable amount of work to develop/customize a simulation framework based on the specific project needs, however, this issue has been addressed over the new versions of the program and become more user-friendly for those with less experience in programming. Review collected by and hosted on G2.com. What problems is OpenSim solving and how is that benefiting you? I have used OpenSim for the following objectives: - To understand the abnormal neuromuscular mechanisms observed in post-stroke walking with descriptive simulations generated from the previously collected experimental measures (i.e. motion capture, instrumented treadmill) using the resulting muscle states from the simulations - Running restricted forward simulations with virtual assistive joint torques to assess impairment-specific assistance profiles to avoid abnormal neuromuscular reactions during post-stroke gait.
