This study investigated nursing students' ways of thinking about home-visit rehabilitation by questionnaire. Eighty-one nursing students who had a practical nurse license in a certain vocation were given a lecture on rehabilitation. Before and after this lecture, they filled out questionnaires about the lecture contents. The rate of valid answers was 96.3%. The lecture created interest among students in home-visit rehabilitation significantly. Subjects who wanted to learn the knowledge and skills of rehabilitation and who felt the necessity of home-visit rehabilitation increased over 15% and 10% respectively. The lecture had a positive effect on almost all students with regard to their understanding of home-visit rehabilitation. I think that home-visit nursing practice is important for learning to relate and communicate with patients including their family and this is necessary knowledge and skill for rehabilitation to some degree. Education of rehabilitation was very useful for understanding home-visit nursing.
The present study was designed to investigate the influence on body sway in standing of changes in visual information by view and saccade stimulation. Subjects were seven healthy adults. In Experiment 1, participants maintained standing with legs together on a center of foot pressure platform with 1) central vision, and 2) periphery vision under eyes open conditions for thirty seconds. The central vision value was significantly decreased compared to the periphery vision. This result implies as the influence of the change of visual information by saccadic eye movement. In Experiment 2, participants maintained standing with legs together and tandem on a center of foot pressure platform with 1) natural view, and 2) saccade stare under eyes open conditions for ten seconds. There was no significant difference between natural view and saccade stare under either condition. The cause of the increased sway was not the influence of the change of vision by saccadic eye movement, which suggests a decrease in the relative quality of information of objects in periphery vision.
Hemiparetic stroke patients have both decreased oxygen consumption and low endurance to exercise. This study examined their physical fitness to quantify the initial deficit and change in oxygen uptake kinetics (VO2 kinetics) during inpatients rehabilitation following stroke. Twenty-nine ambulatory hemiparetic stroke patients were treated in an 8-week program of low intensity aerobic exercise. They undertook a bicycle ergometer test with gas analysis before and after the exercise program to obtain maximum oxygen uptake (VO2 peak), maximum work load (max WR), and VO2 kinetics data. The time constant (τon) and O2 deficit on constant load after exercise training were significantly lower than those in initial measurement by 17% and 10%, respectively. On the incremental load, VO2 peak and max WR were significantly increased by 16% and 17% respectively and ΔVO 2/ΔWR was decreased by 11%. These results show that low-intensity endurance training produces energy efficiency of oxygen uptake kinetics and improves the physical fitness of ambulatory hemiparetic stroke patients.
The purpose of this study was to investigate the relationship between daily physical activity and physical fitness in twenty ambulatory post-stroke patients. The pedometric measurement was made using a caloriecounter in daily life at home and assessed to quantify the time constant (τ on) of oxygen uptake (VO2) and oxygen deficit with gas analysis using a bicycle ergometer. There were negative correlations between the amount of daily walking steps and τ on, as well as the oxygen deficit at the onset of exercise (τ on; r=-0.52, p<0.05, oxygen deficit ; r=-0.61, p<0.01 ), and positive correlations between the amount of daily walking steps and peak VO2, as well as the maximal work load with gas analysis (peakVO2; r=0.61, p<0.01, maximal work load ; r=0.69, p<0.01 ). These results suggest that gait performance of daily physical activity at home was generally related with exercise endurance in ambulatory post-stroke hemiplegia.
The purpose of the present study was to determine (1) whether the pattern of gait with a short leg brace definitely deviated from that of normal gait, and (2) whether a hybrid mass-spring pendulum model proposed in a systems approach was applicable to walking with a short leg brace. Thirty healthy young adults participated in this study. Step rate and Physiological Cost Index during walking on a treadmill were measured while the participants were wearing (a) short leg brace(s) on one leg or on both legs. Walking velocities were 33.3-100.0 m/min for males and 16.7-83.3 m/min for females. The optimal energy-saving gait when using a short leg brace exhibited deviation from the normal gait pattern, because step length was smaller and the step rate was higher. When the velocity exceeded 90 m/min, however, step length was longer and step rate was lower in short leg brace gait than in normal gait. We thought some modifications to the hybrid model were necessary to explain our results.
The purpose of this study was to examine the degree of disorder of dynamic balance in sitting of stroke patients with hemiplegia by calculation of the area of movements of the center of gravity. Subjects were ten hemiplegic patients. Controls were ten young adults and ten eldery adults. The center of gravity point (mean of Y-axis and mean of X-axis) was measured during movements of the center of gravity toward eight points from the center. An octagon was described on section paper by the eight points. This octagon was divided into six triangles. The area of the octagon was calculated by the sum of the area of six triangles. Moreover, the Heron formula was used for calculation of the area of the triangles. The value of hemiplegic patients was significantly decreased compared to the value of controls. Also, there was a significant difference between eyes open and eyes closed in hemiplegic patients only. This study showed the area of movements of the center of gravity area and its characteristic in sitting of hemiplegia patients.
