1. Basics of Biomechanics Dusan Radovanovic, Zurich Duesseldorf 14th Nov. 2006

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

3. Practice

4. 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 20-30% des KG 110-120% des KG 80% des KG 130% des KG Recording min. 10‘‘ 4.0km/h links 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
