Keizo Sakamoto, Yoshihisa Tashiro*, Yoshisada Sato, Futoshi Sugimoto, Etsuo Fujimaki (Dep. of Orthopaedic Surg., Showa Univ., *Dep of Information Science Showa Univ., Tokyo, Japan)
Purpose
A balance is analyzed by means of a three dimensional action analytic equipment when standing with a unilateral foot.
Method
Using a three dimensional action analytic equipment (APAS: ARIEL Performance Analysys System), a balance is investigated when a person stands with a unilateral foot in a mimute. Two TV cameras take a picture of a person standin, 4 with unilateral foot from two directions and these pictures are crowded as reading for a computer. The markers are placed on 18 points of the body. A screen number of a video is shown with the following calculation. 30 sheets/second X 60=1800 sheets.
Result
The patient is 62 Years of age, her height is 160cm and body weight is 57kg. With one minute unilateral foot standing up, there are not different from a right and a left foot standing at the total load to the femoral head. A changing data is slightly large on the points of bilateral knees and ankles as a patient stands with the left foot only.
Conclusion
Changing balance has an influence on the hip compression force.

PREDOMINANT LOWER EXTREMITY WEAKNESS IN STROKE PATIENTS
Byung G. Joo, Min H. Chun, and Sang B. Ha (University of Ulsan, College of Medicine / Asan Medical Center, Seoul, Korea.)
Purpose: This study was undertaken to determine the pathogenesis and functional outcome of unusual type of stroke with predominant weakness of lower extremity.
Method: In retrospective study, medical records and imaging studies of 203 stroke patients were reviewed and analyzed. Functional outcomes were measured with Functional Independence Measure (FIM) on admission and discharge times.
Result: Among 203 stroke patients, 12 cases (5.9%) present predominant weakness in lower extremity. The 6 cases of them showed anterior cerebral artery infarction, 3 corona radiata infarction, I internal capsular infarction, and 2 pontine lesion. Discharge FIM score was higher in patient with lower extremity weakness than upper extremity weakness. Although FIM scores of two groups on admission were similar.
Conclusion: This study confirmed that lesions in somatotopic area of cortex and cerebrospinal tract corresponding to lower extremity are responsible for predominant weakness of lower extremity in certain cases of stroke.
