The purpose of this research was to investigate the lower extremity muscle strength of patients with chronic pulmonary disease. Subjects were 180 patients with chronic pulmonary disease(H-J classification from II to V), and their lower extremity muscle strength were examined. The results showed that patients of H-J classification of II(1.51Nm/kg)and III(1.34Nm/kg)who had showed relatively well physical activities maintained sufficient muscle strength for primary locomotion activities such as stair-climbing and gait. Patients of H-J classification of Ⅳ(1.06Nm/kg)and V(0.61Nm/kg), however, who showed a limitation in physical activities, exhibited a marked decrease in lower extremity muscle strength. It was speculated that the muscle strength level was lower than that necessary for stair-climbing and gait. These results suggest that the evaluation and exercise for patients with chronic pulmonary disease should be performed taking not only their declined respiratory function but also the decrease in their lower extremity muscle strength into consideration.

The purpose of this study is to examine the interrater reliability in isometric hip flexion and extension force measurement by the hand-held dynamometer. 20 healthy subjects participated in this study. We carried out the measurement in condition for not using the belt for the fixation and condition using belt. The measurement was carried out by the 2 testers(Tester A: male, Tester B: female)whose the constitution differed. The hip flexion force value in the measurement which did not use the belt were 19.8kgf(tester A), 17.3kgf(tester B). The hip flexion force value in the measurement which use the belt were 25.0kgf(tester A), 25.8kgf(tester B). The hip extension force value in the measurement which did not use the belt were 27.0kgf(tester A), 23.6kgf(tester B). The hip extension force value in the measurement which use the belt were 30.8kgf(tester A), 31.0kgf(tester B). The force value in the measurement which did not use the belt significantly showed higher value in tester A than tester B. The interclass correlation coefficient between testers in the measurement using the belt was 0.98(hip flexion), 0.97(hip extension). The interclass correlation coefficient between testers in the measurement which did not use the belt was 0.78(hip flexion), 0.80(hip extension). The method using the belt for the fixation is excellent in the hip flexion and extension force measurement in the interrater reliability.
