Day 1:
- Completed: imported data, verified marker positions, scaling, IK, RRA
- Left off: CMC has high residuals because force plate data was bad → cropped data to region of interest
- To do: scale muscle forces → PCSA_child = (mass_child / mass_adult)^(2/3) * PCSA_adult
Assuming constant specific tension (σ):
F_{max,child} = \left( \frac{mass_{child}}{mass_{adult}} \right)^{2/3} F_{max,adult}

Some modeling limitations:
- Need subject-specific optimal fiber length measurements
- Need subject-specific femur geometry
- Would like EMG to validate or constrain activations found by CMC

Day 2:
- Ran CMC on barefoot and AFO trials for one subject (had to add constraint to tibant activation)

After conference:
Discuss about adding the bushing forces by AFO to the model.
Inspired by "ToyLandingModel".
