[Purpose] The purpose of this study was to examine the relationship between grip strength and foot-gripping strength with motor functions among young-old and oldold participants. [Method] In total, 312 elderly women (age: 73.0 ± 6.1 years) participated in this study. They were classified into two groups of the young-old (age: 65-74 years) and the old-old (>75 years). To evaluate physical function, grip strength, foot-gripping strength,and a 5-meter maximum-walking time (5 MWT) were measured, and a 30-second chairstand test (CS-30) and a timed up-and-go test (TUG) were conducted. We used the t-test to compare the two groups. Multiple regression analyses were performed to determine the relationship between strength (grip and foot-gripping) and motor functions. [Results] Among the young-old, all motor functions were a significant and independent factor of foot -gripping strength. However, all motor functions were a significant and independent factor of grip strength among the old-old. [Conclusions] We show that foot-gripping strength is a useful measurement of motor function among the young-old, whereas grip strength is a useful measurement among the old-old.
[purpose] This study aimed to clarify the characteristics of activities ofdaily living and physical and mental function among the elderly with mild cognitive impairment (MCI). [Method] 335 elderly residence participated in this study. Activities of daily living and physical and mental function were compared between two groups defined by Mini Mental State Examination (MMSE) score: (1) MCI group: MMSE score between 24-26, (2) control group: MMSE score above 27. To examine the independent association between cognitive function and potential factors, we used multiple logistic regression analysis. [Results] There were significant differences of duration of education, one-leg standing time and score of Tokyo Metropolitan Institute of Gerontology Index of Competence. The logistic regression analysis results that duration of education and one-leg standing time were significant related factor of cognitive function. [Conclusion] Our findings suggest that duration of education and one-leg standing time were related to cognitive function and they may be useful for early identification of MCI.
The aim of this study was to examine the fat infiltration ratio in the lumbar multifidus (LM), erector spinae muscles (ESM), and psoas major (PM) in elderly female patients with lumbar compression fracture. Subjects were fourteen elderly females aged 65 or over who have been diagnosed with lumbar compression fracture. A total of 11 levels per individual, corresponding to the axial sectional planes through the upper endplate and middle endplate of each lumbar vertebra (L) and the upper margin of the first sacral vertebra (S), were measured LM, ESM, and PM cross-sectional area (CSA). The images were transferred to the Image J. The fat infiltration ratio was a value obtained by dividing the fat infiltration area at CSA (muscle and fat). Range of the fat infiltration ratio in LM and ESM were 13.9~26.5%,and that of PM was 0.4~2.0%.The fat infiltration ratioinLMand ESM were significant higher than that of PM (p<0.01~0.001). The fat infiltration ratio of each muscle did not demonstrate significant correlations with body mass index. There were no significant differences in the fat infiltration ratio of 11 levels inthesamemuscle. The difference in fat infiltration ratio were compared by classifying the fracture and non fracture. There were no significant differences in the mean, the left and the right in both each muscles. These results suggested that LM and ESM fat infiltration rateinpatients with lumbar compression fracture of this study was observed as a whole rather than a focal fatty infiltration.
Abstract: [Purpose] In this study we evaluated performance in the in the longest possible step and investigated its relationship with physical Function. [SubjectsandMethods]The study included 22 among healthy young adults. We measured performance longest possible step, hip extensor muscle, knee extensor muscle, ankle extensor muscle, toe gripping strength, timed up and go test (TUG) and functional reach test (FRT). [Results] The factors affecting performance in the longest possible step, as indicated by repeated measures regression analysis, were the knee extensor muscle and TUG time: performance in the longest possible step was better with a stronger and shorter TUG time. [Conclusion] These results suggested that increasing balance function and muscle strength of knee extensor muscle are important to improving performance in the longest possible stepamong healthy young adult.
This study examined the effectiveness of the newly developed a motorized sway bed that gently sways back and forth on mental sweating response in children with severe physical and intellectual disabilities. Ten children with severe physical and intellectual disabilities participated in this study. Sweating response (SR) on palm at the thenar eminence was measured by capacitance hygrometry. Following a period of rest, each subject was asked to lie down on a static bed for 3 min as control. Then, the subject was given sway stimuli, which was fixed at 0.64 Hz for 3 min. In the results, SR was unchanged during lying of the static bed, whereas it was decreased during sway stimulation. These results suggested that the bed swayed at 0.64 Hz might reduce psychological stress for children with severe physical and intellectual disabilities.
This study evaluated the influence of the existence of sports club affiliation on physical fitness and motor ability in a school period and the relationship between the items of physical fitness and motor ability. The participants were 33 schoolchildren. We investigated the sports club and measured nine items of physical fitness and motor ability. Two groups were compared for physical fitness and motor ability given the existence of sports club affiliation. We investigated the relationship for nine items of physical fitness and motor ability. As a result, none of the measurement items exhibited a significant difference between the two groups given the existence of sports club affiliation. There was a significant correlation between softball throw and grip strength, sit-ups, lateral-repetitive vault,50 m run, and stand-width jump and between sit-ups and lateral-repetitive vault and stand-width jump. There was also a significant correlation between the lateral-repetitive vault and the 50 m run and stand-width jump and between the 50 m run and stand-width jump. It was suggested that a difference does not arise in the physical fitness and motor ability given the existence of affiliation of the sports club, softball throw was an indicator of synthetic motor ability, and the rectus abdominis bore an important role in demonstrating agility and saltation. The schoolchildren with high agility also had high ability in speed and saltation. Abstract: This study evaluated the influence of the existence of sports club affiliation on physical fitness and motor ability in a school period and the relationship between the items of physical fitness and motor ability. The participants were 33 schoolchildren. We investigated the sports club and measured nine items of physical fitness and motor ability.
[Purpose] This study aimed to examine the higher-level functional capacity and cognitive functioning of the elderly with home-based support and care needs receiving daycare services. [Subjects and Methods] Subjects were 26 elderly people with homebased support and care needs (80.5±7.0 years old) receiving rehabilitation services at daycare facilities. The TMIG Index of Competence was conducted to evaluate their higherlevel functional capacity, and the MMSE, TMT-A, N-CAB, FAB, and MST were used to evaluate their cognitive functioning. [Results] A correlation was observed in Instrumental Activities of Daily Living (IADL), which is a subscale of the TMIG Index of Competence,with the N-CAB, FAB, and MST. [Conclusions] The results ndicate that, of theelderlyrequiring home-based support and care, those with lower IADL are associated with a decline in information-processing ability and executive functioning, suggesting that a program aiming to promote information-processing ability and executive functioning may be useful to improve their IADL function, the subscale of the TMIG Index of Competence.
