Candidate Predictive Variables
| GoodHams (1/0) | Mean Stance Dorsiflexion (°) |
| GoodTibia (1/0) | Hip Flexion Range of Motion During Gait (°) |
| GoodTibia and Good Hams (1/0) | Patellar Tendon Advance? (1/0) |
| Strength Score [24] | Gastrocnemius Lengthening? (1/0) |
| Interactions between GoodTibia, GoodHams and Strength Score (two-way) | Femoral Derotation Osteotomy? (1/0) |
| Foot Stabilization Surgery? (1/0) | |
| Gait Deviation Index [30] | Prior Tendo-Achilles Lengthening? (1/0) |
| Normalized Walking Speed | Prior Selective Dorsal Rhizotomy? (1/0) |
| Diagnosis Subtype (Hemi-, Di-, Tri-, or Quadriplegic) | Date of First Gait Analysis |
| Time to Follow-Up Gait Analysis Visit (months) | |
| Ipsilateral Mean Stance Knee Flexion (°) | Age (years) |
