OpenSim musculoskeletal modeling skill for biomechanical simulation and analysis

General

What this skill does


# OpenSim Modeler Skill

## Purpose

The OpenSim Modeler Skill facilitates musculoskeletal modeling and simulation using OpenSim, supporting biomechanical analysis, device design, and clinical research applications.

## Capabilities

- Model scaling to subject anthropometry
- Inverse kinematics and dynamics
- Static optimization
- Computed muscle control
- Joint reaction analysis
- Custom model development
- Prosthetic/orthotic integration
- Muscle force estimation
- Metabolic cost prediction
- Sensitivity analysis
- Model validation workflows

## Usage Guidelines

### When to Use
- Creating subject-specific musculoskeletal models
- Estimating muscle forces and joint loads
- Evaluating prosthetic/orthotic designs
- Supporting surgical planning

### Prerequisites
- Motion capture data available
- Subject anthropometric measurements
- Base musculoskeletal model selected
- Experimental markers defined

### Best Practices
- Validate model scaling with experimental data
- Assess inverse kinematics residuals
- Verify physiological muscle activations
- Document model modifications

## Process Integration

This skill integrates with the following processes:
- Gait Analysis and Musculoskeletal Modeling
- Orthopedic Implant Biomechanical Testing
- Clinical Study Design and Execution
- Human Factors Engineering and Usability

## Dependencies

- OpenSim software
- MATLAB/Python scripting
- Motion capture data
- Musculoskeletal model libraries
- Computational resources

## Configuration

```yaml
opensim-modeler:
  model-types:
    - lower-extremity
    - upper-extremity
    - full-body
    - spine
  analysis-tools:
    - inverse-kinematics
    - inverse-dynamics
    - static-optimization
    - CMC
    - joint-reaction
  output-variables:
    - muscle-forces
    - joint-moments
    - joint-reactions
    - metabolic-cost
```

## Output Artifacts

- Scaled musculoskeletal models
- Kinematics results
- Muscle force estimates
- Joint reaction forces
- Simulation reports
- Validation metrics
- Sensitivity analysis results
- Visualization files

## Quality Criteria

- Model scaling matches subject anthropometry
- Inverse kinematics residuals acceptable

let-fate-decide

Included

Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
