AN APPLICATION OF SAGA PLASTIC AFO TO VARIOUS DISEASES
Toyoko Asami, Hideo Watanabe and Yumi Itoh (Saga Medical School, Saga, Japan)
Purpose:
The Saga Plastic AFO has flexible plastic ankle joints bilaterally. The location of the mechanical ankle joint of the AFO is almost coincide to anatomical axis of the ankle joint. We report the function and the results of our clinical study of Saga Plastic AFO.
Method:
We measured the necessary strength to move the AFO to various direction, and compared to other designs of plastic AFO's.
In clinically, we prescribed about 300 Saga Plastic AFO's to impaired ankle joints due to various diseases since 1984. And we assessed results such as gait ability, period of use, and etc.
Result and Conclusion:
The Saga Plastic AFO showed smooth dorsi-fiexion and plantar flexion, and had good stability to medio-lateral motions. The clinical results of the orthosis were good and patient's gait ability was improved.

THE IMPACT OF RAISED FORE-PART OF SHOE ON BODY SEGMENTAL POSITION DURING AMBULATION
Sun H. Song, Jong Y. Yoo, and Sang B. Ha, (University of Ulsan, College of Medicine/Asan Medical Center, Seoul, Korea)
Purpose: An alteration of body segmental position may occur during ambulation, if the fore-part of shoe is raised (high fore-foot shoe). Our study is designed to investigate the effect of a raised fore-part of shoe (high fore-foot shoe) on the pelvic tilt, lumbar curvature, and kinematics and kinetics of lower extremity during ambulation.
Method: Twenty healthy Korean women were participated in the study using Vicon 370 motion analyzer. Pelvic tilt, lumbar curvature, and three dimensional data of kinematics and kinetics were measured and analyzed.
Result: There was an increase in a stride length while cadence was reduced. No change in walking speed was noted. Double support time was prolonged. There were increases in pelvic tilt and lumbar lordosis. Knee flexion and ankle plantar flexion were decreased.
Conclusion: The raised fore-part of shoes(high fore-foot shoe) affected significantly knee and ankle motions, and also caused an increase in lumbar lordosis. Further study is necessary to apply the raised fore-part shoe to the clinical use.
