Study Arms:
- High-Intensity Treadmill Gait Training (HIGT) (Type: EXPERIMENTAL): High-intensity walking physical therapy with some low intensity therapy.
- Low Intensity Physical Therapy (Type: ACTIVE_COMPARATOR): Low-intensity gait activities, exercises (such as lower extremity strength training with or without weights or electrical stimulation, sit to stands from a chair, mat exercises for upper/lower extremities and core strength, etc.), stretches, balance training activities, and other therapeutic activities (such as transfers, bed mobility training, etc.).

Based on this trial design, predict the completion outcome and termination type (if applicable).
