Risk Factors and Number of Falls as Determinants of Quality of Life of Community-Dwelling Older Adults
imageBackground and Purpose: In older adults, the psychological impact and effects related to the loss of functional capacity are directly related to perceived quality of life (QOL). The predictors of better QOL are increased physical activity, lower prevalence of overweight, lower cases of depression, and lower rate of reported alcohol abuse. On the contrary, the predictors of decreased QOL are female gender, comorbidity, deficient nutritional condition, polypharmacy, loss of mobility, depression and dependency, poor economic conditions, and social isolation and loneliness. Furthermore, QOL in older adults is more dependent on the number of falls than comorbidity. The objective was to investigate the determinants of perceived QOL among independent community-dwelling older adults and to quantify the influence of number of falls and number of risk factors on QOL. Methods: This is a cross-sectional study of 572 older adults (>70 years of age) seen in 10 primary care centers in La Ribera, Valencia, Spain. Comprehensive geriatric assessment was done by 4 nurses in primary care centers. Functional status and sociodemographic and clinical variables were collected. Quality of life was assessed with the EQ-5D scale. Results: Females predominated (63.3%). Mean age (standard deviation) was 76.1 (3.9) years. The male gender (β = .09; 95% confidence interval [CI]: 0.05-0.13) was found to be predictive of better QOL, together with physical activity (β = .04; 95% CI: 0.02-0.06), while the use of drugs affecting the central nervous system (β = −.08; 95% CI: −0.12 to −0.03), overweight (β = −.06; 95% CI: 0.1 to − 0.02), comorbidity (β = −.09; 95% CI: −0.13 to −0.05), the presence of fall risk factors (β = −.02; 95% CI: −0.03 to 0.01), and the number of previous falls (β = −.03; 95% CI: −0.06 to 0.01) had a negative impact upon the EQ-5D Index score. Conclusions: If perceived QOL is used as an indicator of the success of intervention programs, certain factors accompanying the adoption of measures for the prevention of falls may mask the results (failure or success) of the intervention. Because most determinants of QOL are modifiable and physical activity has the potential to improve QOL, this research suggests that physical activity programs should be a component of health care for older adults.
Gait Speed and Dynamic Stability Decline Accelerates Only in Late Life: A Cross-sectional Study in Community-Dwelling Older Adults
imageBackground and Purpose: Incidence of falls increases with age whereas gait speed declines. The purposes of this study were to examine (1) whether gait speed and center-of-mass (COM) velocity declined steadily across ages in a linear fashion among community-dwelling older adults, and (2) whether such decline corresponded to the similar decline in dynamic stability, which is governed by the control of their COM position and COM velocity relative to base of support (BOS). Methods: A total of 184 community-dwelling older adults (≥65 years) participated in the cross-sectional study. The participants were categorized into 5 age groups (65-69, 70-74, 75-79, 80-84, and 85+ years) and were asked to walk on the 7-m walkway at their preferred walking speed. Their speed, gait pattern, relative COM position, and relative COM velocity were measured. Results: Very close relationship was confirmed between a clinical gait speed measurement and the COM velocity (R2 = 0.875, P < .05), which enabled us to use the 2 terms interchangeably. Gait speed decline was not noticeable from 65 to 84 years of age (P > .05), but it accelerated after 85 years of age. This decline was most likely influenced by a reduction in both step length (P < .05) and cadence (P < .05). Similarly, dynamic stability against backward loss of balance changed little between 65 and 84 years of age (P > .05). Yet, it declined significantly after 85 years of age (P < .05), primarily affected by the reduction in the COM velocity relative to the BOS, whereby the COM position relative to the BOS remained constant during their walking. Conclusion: Expected steady decline in gait speed and in the control of gait stability cannot be confirmed. Rather, we found that both declined precipitously only after 85 years of age, when the risk of falls is likely to increase correspondingly.
Reliability and Fall Risk Detection for the BESTest and Mini-BESTest in Older Adults
imageBackground & Purpose: Test stability and test-retest reliability have not previously been reported for either the Balance Evaluation Systems Test (BESTest) or mini-BESTest (mBEST) in a population of older adults with nonspecific balance limitations. Furthermore, no criterion for identifying change greater than chance has been reported in older adults with nonspecific balance problems using either BESTest or mBEST scores. The purposes of this study were to determine test stability over time, test-retest reliability, to identify minimum detectable change for the BESTest and mBEST in a population of older adults with nonspecific balance problems. In addition, the ability of the BESTest and mBEST to identify past fallers was characterized. Methods: This was an observational study with 58 adults 65 years or older with a history of falls or self-reported balance problem. The BESTest and mBEST were administered to all participants at the beginning and end of 4 weeks. Test-retest reliability was calculated with intraclass correlations, and minimum detectable change was calculated at the 95% confidence level (MDC95). Receiver operating characteristics were used to characterize the sensitivity and specificity of the BESTest and mBEST to identify older adults who had previously fallen. Results: Balance scores did not significantly change over a 4-week period. Test-retest reliability for the BESTest (0.86) and mBEST (0.84) was good to excellent. MDC95 scores were identified for the BESTest (8.9) and mBEST (4). Conclusions: The BESTest and mBEST scores were stable and reliable over a period of 4 weeks for a population of older adults with self-reported balance problems or a history of falling. MDC95 scores allow interpretation of change in BESTest and mBEST scores following rehabilitation.
Factors Related to Self-rated Health in Older Adults: A Clinical Approach Using the International Classification of Functioning, Disability, and Health (ICF) Model
imageBackground and Purpose: A growing population of older adults will require health care professionals to become increasingly knowledgeable in geriatric care. Patient ratings, functional measures, and emphasis on health and wellness should be part of geriatric physical therapy practice. The purpose of the current study was to examine relationships between self-rated health (SRH) and movement-related variables in older adults using the International Classification of Functioning, Disability, and Health (ICF) as a research framework. Associations between body mass index (BMI), gait, and balance confidence were also explored. Methods: Thirty older adults (mean age = 74.1 years; 18 women and 12 men) participated in the study and completed the following questionnaires: SRH, Short Activities-specific Balance Confidence scale, Keele Assessment of Participation, and the Neighborhood Environment Walkability Scale–Abbreviated. Spatiotemporal gait parameters, BMI, and isokinetic knee extensor strength were also assessed. Results: Bivariate results indicated significant associations between SRH and double-support time during gait (rs = −0.6, P < .001), gait speed (rs = 0.4, P = .05), step length (rs = 0.4, P = .05), BMI (rs = −0.4, P = .015), and hilliness of neighborhood (rs = −0.4, P = .015). Individual regression models, controlling for education and age, demonstrated that double-support time was the strongest predictor of SRH (R2 = 0.50, P = .001). Comparisons of the low versus high BMI groups indicated more favorable balance confidence and gait characteristics for the low BMI group, particularly in double support (t = −3.8, P = .001). Conclusions: SRH should be considered as a quick, patient-focused assessment of health in older adults. Measures of double-support time and BMI may provide clinicians with useful information about their geriatric patients' overall health and function.
Effect of Physical Activity on the Quality of Life in Osteoporotic Females Living in Residential Facilities: A Randomized Controlled Trial
imageBackground and Purpose: The study aimed to assess the effect of a program of modified Sinaki exercises and Nordic Walking on the life quality in osteoporotic and osteopenic females living in residential care facilities, taking into account their baseline level of activity and risk of falling. The study was designed as a randomized controlled trial. Methods: A sample of 91 females 65 to 98 years of age, the residents of Upper Silesian residential care facilities, was randomized into 4 groups. All groups received the same pharmacological treatment. In group 1 (control group), drugs were the only therapy; in group 2, the therapy was enhanced by program of modified Sinaki exercises; group 3 participated in Nordic Walking workout; and group 4 did both Sinaki exercises and Nordic Walking. Locomotor activity of the participants was estimated from pedometer readings. The risk of falling was assessed with the “Timed Up and Go” Test and the Functional Reach Test. With the QUALEFFO-41 questionnaire, the life quality of the participants was evaluated at baseline and after 12 months of intervention. Results and Discussion: The study revealed that the studied women were at high risk of falling and that their physical activity was relatively low, likewise the quality of their lives. Their satisfaction with life was reduced by poor health, limited mobility, and the lack of social activities. Life quality improved in all 3 intervention groups, but in the control group, it decreased. The results of Bonferroni's post hoc test pointed to statistically significantly better quality of life in groups 2 (P = .01) and 4 (P < .01). Conclusion: Both modified Sinaki exercises and Nordic Walking significantly improved the participants' quality of life, but the most effective therapeutically was the combination of both these forms of physical activity.
Two-Minute Step Test of Exercise Capacity: Systematic Review of Procedures, Performance, and Clinimetric Properties
imageBackground and Purpose: The 2-minute step test (TMST) is one of many alternatives for measuring exercise capacity. First introduced in 1999 as part of the Senior Fitness Test, the TMST has the advantage of requiring limited space, only a few minutes' time, and no expensive equipment. These advantages notwithstanding, the test must be clinimetrically sound if it is to be recommended. We sought therefore to summarize the literature addressing TMST performance and measurement properties. Methods: Relevant literature was identified by searches of 3 electronic databases (PubMed, Scopus, and Cumulative Index of Nursing and Allied Health) and hand searches. Inclusion of an article required that it described use of the TMST of Rikli and Jones and that it focused on adults. Articles published in a language other than English were excluded. Studies were abstracted for information on participants, TMST description, and findings. Results and Discussion: Thirty articles were deemed appropriate based on inclusion and exclusion criteria. The participants in the studies included community-dwelling healthy older adults and adults with assorted pathologies. Studies described varied methods of conducting the TMST. Among tests in which steps for one side were counted over a full 2 minutes, the mean number of steps among populations ranged from 29.1 for patients with chronic stroke to 110.8 for older osteoporotic women. Numerous reviewed studies provide support for the validity of the TMST. Only one study addressed reliability and none focused on responsiveness. Normative data have been proffered. Conclusions: The TMST has been widely used since first introduced, albeit not always as originally described. There is considerable evidence for the validity of the test, but its reliability and responsiveness are not yet firmly established.
Dementia, Comorbidity, and Physical Function in the Program of All-Inclusive Care for the Elderly
imageBackground: Participants in the Program of All-Inclusive Care for the Elderly (PACE) are a unique clinical population of medically complex and highly disabled older adults who qualify for nursing home level care but receive services in the community. A main goal of PACE programs is to prevent further declines in physical function that may necessitate costly institutionalization. This study evaluates how multimorbidity and dementia impact both self-selected gait speed and Timed Up and Go (TUG) in this population. Methods: This study was a cross-sectional design. Sociodemographic information, physical function, comorbidity data, and dementia status on 525 PACE participants were extracted from a quality improvement database. Separate univariable and multivariable linear regression models were used to evaluate the impact of comorbidity status and dementia on gait speed and TUG time. Results: PACE participants overall have a high degree of functional disability, with an average gait speed of 0.66 m/s, an average Short Physical Performance Battery score of 6.0/12, and an average TUG time of nearly 20 s. In the univariable analysis, a higher number of comorbidities and a diagnosis of dementia were associated with greater limitation for gait speed and TUG time. After adjusting for age, sex, strength, and balance, each additional comorbidity was independently associated with 0.015 m/s slower gait speed, as well as a 3.5% increase in TUG time for PACE participants with dementia. Conclusions: Ambulatory PACE participants have average levels of physical function that are dangerously close to thresholds thought to indicate vulnerability for further disability development, hospitalization, and nursing home admission. Both dementia and comorbidity burden are associated with declines in physical function, and the interaction between these risk factors is a telling indicator to functional decline in higher-level ambulatory tasks. PACE program clinicians can use this information to better identify participants at risk for limited physical function. Further research should investigate consequences of functional decline and determine optimal intervention strategies for PACE participants with functional impairments.
Earlier Physical Therapy Input Is Associated With a Reduced Length of Hospital Stay and Reduced Care Needs on Discharge in Frail Older Inpatients: An Observational Study
imageBackground and Purpose: Pressures on hospital bed occupancy in the English National Health Service have focused attention on enhanced service delivery models and methods by which physical therapists might contribute to effective cost savings, while retaining a patient-centered approach. Earlier access to physical therapy may lead to better outcomes in frail older inpatients, but this has not been well studied in acute National Health Service hospitals. Our aim was to retrospectively study the associations between early physical therapy input and length of hospital stay (LOS), functional outcomes, and care needs on discharge. Methods: This was a retrospective observational study in a large tertiary university National Health Service hospital in the United Kingdom. We analyzed all admission episodes of people admitted to the department of medicine for the elderly wards for more than 3 months in 2016. Patients were categorized into 2 groups: those examined by a physical therapist within 24 hours of admission and those examined after 24 hours of admission. The outcome variables were as follows: LOS (days), functional measures on discharge (Elderly Mobility Scale and walking speed over 6 m), and the requirement of formal care on discharge. Characterization variables on admission were age, gender, existence of a formal care package, preadmission abode, the Clinical Frailty Scale, Charlson Comorbidity Index, the Emergency Department Modified Early Warning Score, C-reactive protein level on admission, and the 4-item version of the Abbreviated Mental Test. The association between the delay to physical therapy input and LOS before discharge home was evaluated using a Cox proportional hazards regression model. Results and Discussion: There were 1022 hospital episodes during the study period. We excluded 19 who were discharged without being examined by a physical therapist. Of the remaining 1003, 584 (58.2%) were examined within 24 hours of admission (early assessment) and 419 (41.8%) after 24 hours of admission (late assessment). The median (interquartile range) LOS of the early assessment group was 6.7 (3.1-13.7) versus 10.0 (4.2-20.1) days in the late assessment group, P < .001. The early assessment group was less likely to require formal care on discharge: n = 110 (20.3%) versus n = 105 (27.0%), P = .016. No other statistically significant differences were seen between the 2 groups. In the unadjusted Cox proportional hazards model, the hazard ratio for early assessment compared with late assessment was 1.29 (95% confidence interval: 1.12-1.48, P < .001). Early assessment was associated with a 29% higher probability of discharge to usual residence within the first 21 days after admission than the late assessment. Adjustment for possible confounding variables increased the hazard ratio: 1.34 (1.16-1.55), P < .001. Conclusions: Early physical therapy input was associated with a shorter LOS and lower odds of needing care on discharge. This may be due to the beneficial effect of early physical therapy in preventing hospital-related deconditioning in frail older adults. However, causality cannot be inferred and further research is needed to investigate causal mechanisms.
