Specific treatment and progression for standard care exercise group receiving aerobic and resistance intervention

Week	Standard Care Exercise Group Intervention
1–6	Aerobic Exercise at a moderate exercise intensity (13 on a 20 point Borg Scale) ×  30 mina; 3x/week Resistance exercise: Lower extremity leg press / concentric at 50% 1RMb ×  3 sets × 20 repetitions; 3x/week Lower extremity heel raises / concentric at 50% 1RM** ×  3 sets × 20 repetitions; 3x/week

^aAerobic Exercise will be performed on a seated NuStep Upper Extremity/Lower Extremity Ergometer. This mode of exercise is chosen because it has been shown to elicit sufficient aerobic challenge while at the same time minimizing postural/vestibular demands because of the sitting position and back support

^bLower extremity resistance training will be performed on a seated leg press (Tuffstuff, Pomona, CA). This mode of exercise is chosen because it has been shown to strengthen lower extremity extensors relevant for gait while at the same time minimizing postural / vestibular demands because of the sitting position and back support
