Microprocessor-Controlled Prosthetic Leg

1. Normal walking: Assistive extension with reduced duration;2. Slow walking: Excellent knee joint follow-up flexion with less tiptoe and less fatigue.3. Quick walking: assistive symmetric extension with a flexion angle of 60-65 degrees.4. Stair ascending: assistive extension during standing mode and flexion control during swing mode.5. Stair descending: natural gait with sole grounding and less buffering by yielding6. Uphilling: natural gait with reduced tiptoe7. Downhilling: a safer method of downhilling that involves yielding at any angle.8. Standing up: assistive extension that effectively reduces the burden on an intact leg9. Deep squat: a deep squat that is well-balanced and performed in synergetic assistive flexion.10. Rest while standing: body support on two legs with less burden on the intact leg
