  2. History • Summer 1997 until April 1998 Gaitway Kistler System under test in own practice • Study of patients with knee disorders • Publication • „Gait- and motion analysis in physiotherapy. Possibilities of therapy for knee disorders for leisure athletes by altering the running technique". • Scientific Award of Association for Sports Medicine Switzerland

  3. Practice

  4. Practice Treadmill Gaitway used since May 1998

  5. Used Measurement System Gaitway

  6. Action – Reaction„Center of Pressure“

  7. Registration of Patients

  8. Acceptance

  9. Vertical Bottom-Reaction-Force-Curve 130% des KG 110-120% des KG 80% des KG links Recording min. 10‘‘ 4.0km/h 20-30% des KG rechts walking in normal shoes

  10. Ideal Vertical Bottom-Reaction-Force-Curve walking 4.03 km/h cadence 112 / min. 10“ 9x left 8x right

  11. Horizontal (frontal) Bottom-Reaction-Force-Curve left right Push-off-phase Standing phase Heel strike First peak

  12. Vertical Bottom-Reaction-Force-Curve 2.5 x KG running, barefoot 8 km/h

  13. Practical Examples

  14. Arthritis in the upper ankle (left) & Femoropatellares syndrome(right) 4 weeks later

  15. Calcaneal Spur 8 weeks later walking

  16. Calcaneal Spur 10 weeks later running

  17. Tendovaginitis Tibialis posterior, Flexor hallucis longus and Flexor digitorum longus

  18. Jumpers knee left 21 days later

  19. “ Runners knee “ running shoes barefoot

  20. VKB plastic right 2 years after operation

  21. Several surgeries left knee 8 km/h 8 kmh 13 km/h

  22. Knee pains left > right after 10 min. running with heel run technique Forefoot run technique with running shoes barefoot

  23. Gonarthritis right heel run technique forefoot run technique

  24. Patellae multiple fracture heel run technique forefoot run technique

  25. Total implant left knee

  26. VKB plastic 3 weeks after surgery 6 weeks after surgery 8 weeks after surgery 12 weeks after surgery

  27. Running after 12 and 14 weeks

  28. Femoropatellares syndrome 8 weeks later

  29. Gonarthritis 3 months later
