Background: Early ambulation has been shown to be associated with shorter hospital stay and better clinical outcomes in patients with acute heart failure (HF). Early mobilization program in combination with structured exercise training is recommended, but has yet to be developed and implemented in HF. Methods and Results: We developed a progressive mobilization program for HF patients that classifies the mobilization process into 7 stages based on disease condition and physical function. We retrospectively analyzed 136 patients with acute HF (80±11 years), who were assigned either to the mobilization program (intervention group, n=75) or to usual care (control group, n=61). The program was safely implemented without any adverse events. Hospital stay was significantly reduced in the intervention group compared with the control group (33±25 vs. 51±36 days, P<0.01). The intervention group had higher activities of daily living (ADL) score at discharge evaluated using the Barthel index (64±38 vs. 49±36, P<0.05). The intervention group also had a higher percentage of discharge to home (71% vs. 52%, P<0.05) and a lower rate of HF-related readmission (16% vs. 36%, P<0.05) compared with the control group. Conclusions: The progressive mobilization program for acute HF was feasible and was associated with better ADL and reduced hospital stay, leading to improvement of clinical outcome.

Highly precise positioning control is based on mechatronics. Nanotechnology, especially nanometer positioning technology with high-speed and robust positioning feedback control, is used in various technical fields including measuring systems, magnetic recording and the semiconductor industry. To date, various actuator systems have been proposed, but the structural models have working distance of either less than a millimeter or more than ten millimeters. A structural model with working distance of several millimeters has not been reported in the relevant literature. We propose an actuator structural design that would enable production of actuator systems with such working distances. This actuator has a voice coil motor and a new guide with an elastic support mechanism consisting of a special spring that is restricted to movement in only one direction. This ESM causes no lost motion, friction with motion, or mechanical play. The voice coil motor thrusts and displaces the elastic support mechanism linearly. Therefore, highly precise positioning control can be realized using a simple controller. This paper describes evaluation of the positioning control method from the displacement of ESM and presents basic data for development of future nano-actuator systems.
