1-Scale Modeling
Physical Examination
Scaling is performed based on a combination of measured distances between x-y-z marker locations and manually-specified scale factors. The scaling step scales the mass properties (mass and inertia tensor) of the model, as well as the dimensions of the body segments. Many of the elements attached to the body segments, such as muscle are also scaled. By matching up anatomic landmarks on a generic model with anatomic landmarks we measure in our lab , we can stretch and squish the generic model to match your body–the scaled model will be the same height, the same weight, and will even have any asymmetries (e.g. a leg length discrepancy) that you have. Scaling a model in OpenSim with motion data , EMGs and in some cases syncrnized with IMUs for a cyclist is essential for achieving accurate biomechanical simulations. This accuracy, in turn, can aid in performance improvement in several ways:
Personalized Training Plans for tailored training plans that target specific muscle groups and movement patterns.
growing age children
Optimized Bike Setup
Injury Prevention
Technique Refinement
Muscle-Specific Training
Energy Expenditure Optimization
Rehabilitation and Return from Injury
Real-time or post-ride analysis using the scaled model can provide immediate feedback to the cyclist and coach. This allows for ongoing adjustments and improvements in training plans and technique.
If a cyclist experiences an injury, a scaled model can be used to understand how the injury affects their biomechanics.
