Factors related to indoor prosthetic use in individuals with unilateral lower limb amputation.

Background: The rate of indoor prosthetic use in people with lower limb amputation (LLA) is lower than that of outdoor use. Very few studies of indoor prosthetic use have been conducted, and no studies have focused on the perspective of instrumental activities of daily living (IADLs).

Objectives: To assess the indoor prosthetic use of individuals with unilateral LLA from the perspective of IADLs.

The relationship between balance ability and walking ability using the Berg Balance Scale in people with transfemoral amputation.

Background: Few reports have examined the relationship between balance ability and walking ability in people with transfemoral amputation using the Berg Balance Scale.

Objectives: To assess the construct validity (known groups discrimination, convergent validity, and floor/ceiling effects) of Berg Balance Scale for people with transfemoral amputation.

Study Design: Cross-sectional study.

Perception of leaning backward while standing and patellar movement.

[Purpose] The purpose of this study was to investigate the relationship between the patellar movement and the standing backward leaning perceptibility. [Subjects and Methods] Fourteen volunteers who were confirmed presence of upward patellar movement during backward leaning from the quiet standing posture participated in this study. The quiet standing position, the standing backward leaning position at patellar movement onset and standing position perceptibility were measured.

Periodical measurement of urine volume in the bladder during sleep: Temporary volume reduction suggestive of absorption.

Objectives: To clarify the variance of urine volume in the urinary bladder during sleep.

Methods: Overnight measurements of urinary bladder capacity during sleep were carried out using transabdominal real-time 3-D ultrasound or an automatic capacity recorder, Yuririn, in 24 volunteers of various ages.

Results: Two types of patterns were observed in the increasing curve of capacity; namely, gradual elevation pattern when overnight urine production was less than functional bladder capacity and steep-flat pattern when it was more than functional bladder capacity.

Launch device using endlessly single-mode PCF for ultra-wideband WDM transmission in graded-index multi-mode fiber.

We demonstrated ultra-wideband wavelength division multiplexing (WDM) transmission from 850 to 1550 nm in graded-index multi-mode fiber (GI-MMF) using endlessly single-mode photonic crystal fiber (ESM-PCF) as a launch device. Effective single-mode guidance is obtained in multi-mode fiber at all wavelengths by splicing cm-order length ESM-PCF to the transmission fiber. We achieved 3 × 10 Gbit/s WDM transmission in a 1 km-long 50-μm-core GI-MMF.
