Abstract Background Fall prevention in older adults is an important task. Lower extremity function is a main focus in fall prevention. There are few previous studies focusing on core stability. The purpose of this study was to investigate the relationship between fall risk and core stability. Methods The study participants were 33 community-dwelling older adults (mean age: 65±17 years old; 5 men, 28 women). The fall risk was assessed using the Fall Risk Index-21 (FRI-21). Core stability measured the retention time of Side Bridge (SB) and Front Bridge (FB). Secondary outcome measures included lower extremity muscle strength (knee extension, hip abduction) and physical function (two-step test). Statistical analysis investigated the correlation between the measurement items. Results We found a significant negative correlation between FRI-21 and SB (r = -0.51, p<0.01) and FRI-21 and FB (r = -0.47, p<0.01). We also found a correlation between FRI-21 and the two-step test (r = -0.40, p<0.05). There was no significant correlation between FRI-21 and lower extremity muscle strength. Discussion FRI and Core stability showed moderate correlation. It suggests that the core and hip muscle functions involved in posture retention are involved with fall. Conclusion The risk of falls in older adults was related to core stability. If the core stability of older adults improves, it may help to reduce the risk of falling. Therefore, it is useful to consider core stability in the assessment of fall risk.

Abstract Background The effects of group exercise on the physical function of community-dwelling older adults remain unclear. The changes in lower extremity muscle strength, timed up and go (TUG) time, and the motor fitness scale (MFS), over time, among older adults who expressed a willingness to participate in community-based physical exercise groups, were determined using multilevel modelling. Methods We analyzed data of 2407 older adults between April 2010 and December 2019 from the registry of physical tests of community-based physical exercise groups. We conducted a retrospective cohort study to assess the effect of physical exercise on lower extremity muscle strength, TUG time, and MFS scores. The durations of the exercises were evaluated by frequency of physical test’s participate. Results A deterioration in lower extremity muscle strength was found in the short-term participant group only. However, in the mid-term and long-term participation groups, lower extremity muscle strength showed a trend of improvement. The TUG time and the MFS score were negatively correlated with increasing age in both groups divided by the duration of participation. However, there was a slower rate of deterioration in the long-term participation group. Discussion Lower extremity muscle strength, TUG time, and MFS scores decline with increasing age and there were differences in the slope of deterioration that depended on the duration of participation in community-based group exercise. Conclusion Participation in group exercise improved lower extremity muscle strength, TUG time, and MFS scores of older adults living in a community. The positive effects of group exercise were dependent on long-term participation.

Risk Of Falls

An age-related decline in balance, gait and lower-extremity muscle strength measures may lead to increased risk of falls and fractures. Previous studies have reported a possible non-linear age-related decline in these measures, but the choice of methodological approach has limited its interpretation. Healthy community-dwelling women (n=212) 21–82 years of age were evaluated for strength [Nicholas MMT (manual muscle tester)], gait [CSA (clinical stride analyser)], activity [HAP (human activity profile)] and static and dynamic balance [CBS (Chattecx balance system), LBT (Lord's balance test) and the ST (step test)]. A GAM (generalized additive model) was developed for each outcome variable to estimate the functional relationship, with age as a continuous variable. Performance was maintained until 45–55 years of age, depending on the outcome measure. Thereafter a decline in performance was evident with increasing age in all measures. Overall, a significant non-linear relationship with age was demonstrated for lower-extremity strength measures (MMT), velocity and double support duration of gait (CSA) and some clinical and laboratory balance tests [ST, LBT (eyes open) and the CBS]. Linear relationships were demonstrated by the LBT with eyes closed and activity measures. Balance, lower-extremity muscle strength and gait may decline non-linearly with age. Our study suggests possible threshold effects between age and balance, muscle strength and gait measures in women. Further research into these threshold effects may have implications for the optimal timing of exercise and other interventions to reduce the risk of falls and fractures.

Objective: Declines in physical and cognitive functioning often co-exist through aging. Gait-related parameters have been related to cognitive function, although it is unclear whether other measures of physical functioning are similarly related to cognition. Here, we analyzed the relationship between physical functioning with cognition in older adults. Methods: In total, 116 participants were included (M age = 69 years, SD = 6; 71% women). We quantified cognitive functioning using the Montreal Cognitive Assessment (MoCA) and executive functioning tasks (Digit Span Forward minus Backward and verbal fluency tests). Physical function measures included gait speed, Short-physical Performance Battery (SPPB), five-times Sit-to-Stand Test, the Timed Up and Go (TUG) test, the Six-minute Walk Test (6MWT), and lower extremity muscle strength. We used multiple linear regression analyses to explore the association between cognitive measures and each measure of physical functioning, adjusting for age, sex, education, and RCT. Results: We observed a positive association between muscle strength and the MoCA (b = 0.84, SE = 0.40, 95%CI 0.05–1.64) after controlling for covariates. Significant associations were also found between the five-times-sit-to-stand test (b = -0.63, SE = 0.26, 95%CI -1.15–-0.12), TUG (b = -1.13, SE = 0.57, 95%CI -2.26–-0.01), 6MWT (b = 0.04, SE = 0.02, 95%CI 0.01–0.07), and lower extremity muscle strength (b = 1.92, SE = 0.93, 95%CI 0.09–3.77) with the FAS verbal fluency test, and between the TUG (b = -0.62, SE = 0.24, 95%CI -1.11–-0.14) with animal naming. Conclusion: In community-dwelling older adults, higher levels of muscle strength, dynamic balance and cardiorespiratory fitness were positively related with global cognition and executive control measures.

Abstract Individuals who have suffered a stroke are at risk for developing cognitive impairment and dementia. Thus, it is important to identify modifiable risk factor for cognitive decline in this population. Among older adults without a history of stroke, greater muscle strength is associated with better cognitive function. Whether this relationship also exist in older adults with a history of stroke is not known. Thus, we aimed to examine whether cognition, as measured by both the Montreal Cognitive Assessment (MoCA) and the 13-item Alzheimer’s Disease Assessment Scale-Cognitive (ADAS-Cog 13), is associated with lower extremity muscle strength in adults with chronic stroke (> 1 year post stroke). Ninety-one community-dwelling adults, aged 55 years and older, with chronic stroke were included in this analysis. Isometric strength of the quadriceps was measured bilaterally in kilograms. Two linear regression models were constructed to determine the independent association of quadriceps strength (mean kilograms of both legs) with: 1) MoCA; and 2) ADAS-Cog 13, after controlling for age, sex, and mood. Mean quadriceps strength was independently associated with both MoCA and ADAS-Cog scores, after accounting for age, sex, and mood. Specifically, quadriceps strength explained an additional 5.6% of the variable in MoCA scores; total variance explained by the model was 12.0%. For ADAS-Cog 13, quadriceps strength explained an additional 5.4% of the variance; total variance explained by the model was 16.5%. Our current cross-sectional results suggest that the maintenance of muscle strength may be important for cognitive health in older adults who have suffered a stroke.

Abstract Background: Falls increase as people age and decrease the quality of life. Even though fall interventions have received great attention, fall incidence rates have still arisen. In order for older adults to reap the benefits of evidence-based fall interventions, a challenge of implementation in the real world and right context must be met. Understanding experiences, facilitators, and barriers of fall prevention among four major ethnic groups in the Unites States could be extremely valuable. Objective: The aim of this study was to describe experiences and highlight facilitators and barriers on fall and fear of falling interventions among ethnically diverse community-dwelling older adults. Methods: Four ethnically specified (African American, Asian, Hispanic and Non-Hispanic White) focus groups were conducted. A total of 28 older adults and four family caregivers were interviewed. Interviews covered experiences on falls and fear of falling, attitudes, factors, consequences, risk assessment, and interventions. Data were organized and analyzed with the NViVo software. Results: Falls related experiences and behaviors were multifaceted and varied. Three themes related to falls experiences and behaviors were identified, 1) falls prevention versus fear of falling amplification; 2) role identity, culture and family considerations; and 3) take care of you, take care of me. Facilitators of fall prevention were integration of individual learning within a group meeting, providing appropriate assistive devices and promoting environmental safety. Barriers were inconsistent fall risk assessments, low fall risk awareness and acknowledgment, and balance and visual impairment.
