Influences of trunk stability on exercise performance of closed kinetic chain of upper and lower limbs.

[Purpose] This study aimed to examine whether trunk stability is related to closed kinetic chain motor performance of the upper and lower limbs. [Participants and Methods] In this study, 27 healthy male university students participated. Trunk stability was measured under two conditions, with and without rhythmic stabilization, as a proprioceptive neuromuscular facilitation procedure.

Localization of small renal tumor by dynamic computerized tomography.

Herein we report on 4 cases of renal tumor whose diameter was less than 3 cm. A mass lesion was suggested by renal echography in mass screening program. Renal dynamic computerized tomography (CT) with bolus injection can delineate a mass lesion clearer than ordinary plain and enhanced CT, and renal angiography.
