Functional adaptations to physical activity and inactivity.

Rather than focusing on the performance criteria accompanying adaptation to physical activity, this paper emphasizes the magnitudes of alteration in the function of the circulatory, respiratory, and metabolic systems with adaptation. It is our opinion that the limitation of maximal aerobic power resides in the transport of oxygen to working muscle by the circulation. Increases in maximal aerobic power that accompany physical conditioning are attributed primarily to increased maximal muscle blood flow and muscle capillary density. The increase in the oxidative potential of skeletal muscle after training is presented as the mechanism by which capacity for submaximal work is augmented.

[Physio-pathologic aspects of aging--possible influence of physical training on physical fitness].

Two physiological parameters seem to be of major importance in maintaining physical functioning in the elderly: a capacity to perform aerobic exercises (endurance fitness) and an ability to do anaerobic work, especially maximal muscle force and power. Regular physical activity helps in maintaining these parameters at levels enabling normal functioning at everyday's living, contributing therefore to preservation of functional autonomy and independence in the elderly.

[Clinical techniques for use in neurological physical examinations. III. Sensory functions].

AIMS: The purpose of this work is to focus on the main practical aspects of the techniques used for the neurological physical examination of the sensory functions and to present an approach for the practice of this study. DEVELOPMENT: Despite the difficulty often involved in interpreting its results, today the formal examination of sensation is still an important part of a complete neurological evaluation and remains valid in the search for a correct diagnosis and suitable treatment. We recommend clinicians to carry out a brief but consistent and effective exploration in a systematic, flexible and orderly manner to check for abnormalities in the sensory functions. Should any anomalies be detected, then a more detailed and thorough neurological exploration must be performed selectively. We present a detailed review of the practical aspects of the main techniques used in the physical examination of this neurological category. In addition to the tests used to examine the peripheral and cortical sensory systems, we also describe other techniques designed to trigger pain or other sensory symptoms due to radicular lesions or injury to the median nerve. CONCLUSIONS: We present a detailed description of the main clinical techniques used in the neurological physical examination of the sensory functions, as well as an approach that allows them to be performed on adult patients. In addition, we underline the importance of physically examining the sensory functions in contemporary medicine and the need to continually perfect the way these techniques are performed in order to achieve an efficient clinical practice.

The effects of multidimensional home-based exercise on functional performance in elderly people.

BACKGROUND: This study tested the hypothesis that a home-based exercise program would improve functional performance in elderly people. METHODS: We conducted a 6-month, single-blinded, randomized controlled trial. 72 community dwelling men and women (aged >/=70 years) with self-reported and laboratory-based functional impairment were recruited for the study. Participants were randomly assigned to either a home-based progressive strength, balance, and general physical activity intervention or an attention-control group that received home-based nutrition education. Functional performance was measured in the laboratory using the Physical Performance Test (PPT) and the Established Populations for Epidemiologic Studies of the Elderly (EPESE) short physical performance battery. Physiologic capacity was measured by strength (one repetition maximum), dynamic balance (tandem walk), gait speed (2-meter walk), and cardiovascular endurance (6-minute walk). RESULTS: 70 participants (97%) completed the 6-month trial. Compliance with study interventions within each group ranged from 75% in controls to 82% in exercisers. PPT increased by 6.1 +/- 13.4% in exercisers and decreased by 2.8 +/- 13.6% in controls (p =.02). EPESE improved by 26.2 +/- 37.5% in exercisers and decreased by 1.2 +/- 22.1% in controls (p =.001). Dynamic balance improved by 33.8 +/- 14.4% in exercisers versus 11.5 +/- 23.7% in controls (p =.0002). There were no differences between groups in the change in strength, gait speed, or cardiovascular endurance. CONCLUSIONS: Minimally supervised exercise is safe and can improve functional performance in elderly individuals. The improvements in functional performance occurred along with improvements in balance but without a significant change in muscle strength or endurance.

[Disability and quality of life of stroke survivors: evaluation nine months after discharge].

INTRODUCTION AND AIM: After acute episode, a great number of individuals who survive a stroke have impairments that impede them to carry out with autonomy a set of basic activities of daily life and instrumental activities of daily life. The clinical evaluation health self perception is a useful element on patient's recovering process. The purpose of this study was to evaluate post-stroke functional health status and quality of life. PATIENTS AND METHODS: After identification of a cohort of admitted patients at a general hospital, those were contacted by phone nine months after discharge. The collected tool sent by mail included the COOP WONCA charts, Frenchay Activities Index, Barthel Index, Rankin scale and a set of socio-demographic variables. RESULTS: Participants survival rate was of 81%. The physical functioning and the capacity to perform daily activities were the most affected ones, impairing the patients of making a set of basic and instrumental daily activities. The emotional state and health self-perception are also correlated to disability. CONCLUSIONS: The results suggest a significative percentage of stroke survivors maintaining a moderate or severe disability (47.8%) requiring the presence of caregiver helping self-care. Collected data enhances that stroke survivors have severe physical dysfunction associated to emotional and psychological disturbances.

Grip strength, postural control, and functional leg power in a representative cohort of British men and women: associations with physical activity, health status, and socioeconomic conditions.

BACKGROUND: Understanding the health, behavioral, and social factors that influence physical performance in midlife may provide clues to the origins of frailty in old age and the future health of elderly populations. The authors evaluated muscle strength, postural control, and chair rise performance in a large representative prospective cohort of 53-year-old British men and women in relation to functional limitations, body size, health and activity, and socioeconomic conditions. METHODS: Nurses interviewed 2984 men and women in their own homes in England, Scotland, and Wales and conducted physical examinations in 2956 of them. Objective measures were height, weight, and three physical performance tests: handgrip strength, one-legged standing balance time, and time to complete 10 chair rises. Functional limitations (difficulties walking, stair climbing, gripping, and falls), health status, physical activity, and social class were obtained using a structured questionnaire. RESULTS: Those with the worst scores on the physical performance tests had higher rates of functional limitations for both upper and lower limbs. Women had much weaker handgrip strength, somewhat poorer balance time, and only slightly poorer chair rise time compared with men. In women, health problems and low levels of physical activity contributed to poor physical performance on all three measures. In men, physical activity was the predominant influence. Heavier weight and poorer socioeconomic conditions contributed to poorer balance and chair rise times. CONCLUSIONS: In this representative middle-aged group, physical performance levels varied widely, and women were seriously disadvantaged compared with men. In general, physical performance was worse for men and women living in poorer socioeconomic conditions with greater body weight, poorer health status, and inactive lifestyles. These findings support recommendations for controlling excess body weight, effective health interventions, and the maintenance of active lifestyles during aging.

Self-efficacy beliefs and perceived declines in functional ability: MacArthur studies of successful aging.

Longitudinal data from a cohort of older men and women, aged 70-79, were used to test the hypothesis that stronger self-efficacy beliefs would protect against onset of perceived functional disabilities over a 2.5-year follow-up, independent of underlying physical ability. Standard self-report scales were used to assess perceived functional disabilities, ranging from mild performance difficulties (measured by a 5-item scale based on items by Nagi) to more severe disabilities (measured by the 7-item Katz Activities of Daily Living Scale [ADL]). Performance-based measurements of strength, balance, and gait provide more objective assessments of physical abilities. Self-efficacy beliefs were measured in terms of beliefs relating to managing interpersonal relationships and beliefs relating to managing more instrumental daily activities. Gender-specific multiple regression models revealed that weaker instrumental self-efficacy beliefs predicted declines in reported functional status as measured by the Nagi performance scale among both men and women, independent of standard sociodemographic, health status, and health behaviors. Among men, instrumental efficacy beliefs were also negatively related to reports of onset of Katz ADL. Self-efficacy beliefs were unrelated to measured changes in actual physical performance abilities for both men and women. These findings suggest that self-efficacy beliefs have significant impacts on perceptions of functional disability, independent of actual underlying physical abilities. Through such influences on perceptions of disability, self-efficacy beliefs may importantly affect lifestyles and quality of life at older ages.

Long-term quality of life and neuropsychologic functioning for patients with CNS germ-cell tumors: from the First International CNS Germ-Cell Tumor Study.

This study evaluated the quality of life and neuropsychologic functioning among patients enrolled between 1989 and 1993 in the First International CNS Germ-Cell Tumor Study. Quality-of-life questionnaires (Short Form-36 or Child Health Questionnaire) were completed on 43 patients at median follow-up of 6.1 years after diagnosis (range, 4.5-8.8 years), and intellectual and academic testing was performed on 22 patients. Psychosocial and physical functioning of patients aged 19 years and older at follow-up was within the average range, whereas the same functioning for patients aged 18 years and younger, as reported by their parents at follow-up, was low average and borderline, respectively. Overall psychosocial and physical health summary scores were positively correlated with age at diagnosis for both groups combined. Those who received CNS radiation therapy (n = 29) reported significantly worse physical health, but similar psychosocial health, compared with those treated without radiation. Neuropsychologic testing indicated full-scale and verbal IQ, reading, spelling, and math skills in the average range, and performance IQ in the low average range. Intelligence and math skills were positively correlated with age at diagnosis. Those with germinomas significantly outperformed those with nongerminomatous/ mixed tumors on all neuropsychological measures administered. Younger patients diagnosed with CNS germ-cell tumors are at increased risk for psychosocial and physical problems as well as neuropsychologic deficits. Exposure to irradiation adversely affects overall physical functioning, whereas tumor pathology appears to be a salient neurocognitive risk factor. Collaborative and randomized studies are required to further elucidate the late effects arising from factors such as age at diagnosis, tumor histology, level of irradiation therapy, and chemotherapy toxicity among these young and potentially curable patients.

Change in functional disability of geriatric patients in a family medicine program: implications for patient care.

Multi-dimensional functional impairments of a sample of 130 new patients, aged 60 years and older, at a family medicine center were previously described. Of these, 48 persons representing the combinations of impairment originally present were selected by means of modified random sampling for follow-up 13 to 27 months later (m = 20 months). Patients were assessed both at the time of the initial visit and on follow-up with the Older Americans Resources Services (OARS) Multi-dimensional Functional Assessment Questionnaire, an instrument permitting assessment of functional status in five areas of personal functioning: social, economic, mental health, physical health, and the ability to perform activities of daily living (ADL). Fourteen of the 130 initial subjects died during the follow-up interval. Impairments in mental health, physical health, and ADL were associated with increased risk of mortality; but impairments in social and economic functioning did not increase risk. For the survivors there was decline in economic and mental functioning and little, if any, change in social resources or the ability to perform activities of daily living. However, there was notable improvement in their physical functioning.

Pain in ambulatory AIDS patients. I: Pain characteristics and medical correlates.

The characteristics and impact of pain were evaluated in a prospective cross-sectional survey of 438 ambulatory AIDS patients recruited from health care facilities in New York City. More than 60% of the patients reported 'frequent or persistent pain' during the 2 wks preceding the study. Patients with pain reported an average of 2.5 different pains. On the 0-10 numerical scale of the Brief Pain Inventory (BPI), mean pain intensity 'on average' was 5.4 (SD = 2.2; range = 0-10), and mean pain 'at its worst' was 7.4 (SD = 2.0; range = 1-10). The pain-related functional interference index (sum of the seven item BPI subscale) was 42.6 (SD = 17.2; range = 0.70). Demographic variables were not associated with the presence of pain, but the number of current HIV-related symptoms, treatment for HIV-related infections, and the absence of antiretroviral medications were significantly associated with the presence of pain. Female gender, non-Caucasian race, and number of HIV-related physical symptoms were significantly associated with pain intensity. Presence of pain and increasing pain intensity were significantly associated with greater impairment in functional ability (Karnofsky Performance Status, BPI functional interference index) and physical symptom distress (Memorial Symptom Assessment Scale). Results demonstrate high levels of pain and pain-related functional impairment among patients with AIDS. The presence and intensity of pain are associated with more advanced HIV disease and pain intensity is also associated with demographic factors (gender, race).

Discharge functional capacity and self-efficacy of men after coronary artery bypass graft surgery.

Fatigue and activity intolerance are reported to persist for several weeks after discharge after coronary artery bypass graft (CABG) surgery. This may be due to early discharge, which limits the time, prior to leaving hospital, to achieve an adequate functional level for the performance of many activities of daily living. Alternatively, it may be related to level of self-confidence, or self-efficacy (SE), in one's ability to perform physical activity. High SE may result in overexertion during the vulnerable, early post-discharge phase of recovery, whereas low SE may cause underexertion. The limited number of cardiac rehabilitation programs in Canada for this phase of recovery precludes close guidance and monitoring during physical activity for most patients. Prior to prescribing safe and effective home exercise at discharge, it is essential to assess functional level, cardiovascular responses to physical activity, and perceived level of confidence in ability to perform physical activity. The purpose of this descriptive study was to measure functional capacity, hemodynamic responses to low level exercise, and self-efficacy at discharge after CABG surgery. Twenty-one men completed a self-efficacy questionnaire (SEQ) and a low-level graded exercise test (LL-GXT) using a modified Naughton protocol, on the day of discharge. Results revealed that discharge functional capacity ranged from 1.0 METs to 4.3 METs, peak heart rate ranged from 82-150 beats.min-1, and peak systolic blood pressure from 114-200 mmHg. Subjects were more confident in their ability to tolerate psychological stressors than physical activity. Furthermore, there was no correlation between SE for physical activity and the physiological variables except HR.(ABSTRACT TRUNCATED AT 250 WORDS)

Intensive weight loss program improves physical function in older obese adults with knee osteoarthritis.

OBJECTIVE: Physical function and body composition in older obese adults with knee osteoarthritis (OA) were examined after intensive weight loss. RESEARCH METHODS AND PROCEDURES: Older obese adults (n = 87; > or = 60 years; BMI > or = 30.0 kg/m2) with symptomatic knee OA and difficulty with daily activities were recruited for a 6-month trial. Participants were randomized into either a weight stable (WS) or weight loss (WL) program. Participants in WL (10% weight loss goal) were prescribed a 1000 kcal/d energy deficit diet with exercise 3 d/wk. WS participants attended health information sessions. Body composition and physical function (Western Ontario and McMaster University Osteoarthritis Index, 6-minute walking distance, and stair climb time) were assessed at baseline and 6 months. Statistical analysis included univariate analysis of covariance on 6-month measurements using baseline values as covariates. Associations between physical function and body composition were performed. RESULTS: Body weight decreased 8.7 +/- 0.8% in WL and 0.0 +/- 0.7% in WS. Body fat and fat-free mass were lower for WL than WS at 6 months (estimated means: fat = 38.1 +/- 0.4% vs. 40.9 +/- 0.4%, respectively; fat-free mass = 56.7 +/- 0.4 vs. 58.8 +/- 0.4 kg, respectively). WL had better function than WS, with lower Western Ontario and McMaster University Osteoarthritis Index scores, greater 6-minute walk distance, and faster stair climb time (p < 0.05). Changes in function were associated with weight loss in the entire cohort. DISCUSSION: An intensive weight loss intervention incorporating energy deficit diet and exercise training improves physical function in older obese adults with knee OA. Greater improvements in function were observed in those with the most weight loss.

Respiratory muscle function in physically active elderly women.

This study was performed in 52 women, aged 60 to 76 years: 27 were engaged in a gymnastics program, 3 h a week, for at least 2 years; 25 were age-matched controls. All were lifelong nonsmokers, free of disease symptoms and lived independently at home; none had previously engaged in exercise programs. Spirometry included volumes, flows and maximal voluntary ventilation (MVV); maximal mouth pressures both inspiratory (MIP) and expiratory (MEP) were also measured. The two groups differed only in the mean value of MEP (cm of water) which was 107.7 +/- 37.3 S.D. in the active group and 87.4 +/- 22.8 S.D. in the controls (P = 0.028). MIP and MVV were also higher in the active group but the differences were not significant. However, a significant correlation between MVV and both MIP and MEP was only found in the active group, suggesting a relation between muscular endurance and strength. This exercise program, although not oriented towards the respiratory system, improved the performance of the respiratory muscles probably by an effect on the abdominal musculature.

The development of a battery of measures for assessing physical functioning of chronic pain patients.

The physical performance of chronic pain patients is of major concern both for their assessment and for treatment evaluation. However, there are few widely used physical tests, a shortage of reliability and validity data on published tests, and an over-reliance on self-report or on clinical measures of dubious generalisability. A set of tests was designed to cover speed and endurance in walking, stair climbing, standing up from a chair, sit-ups, arm endurance, grip strength, and peak flow. Standard instructions and testing conditions were used by a trained tester on a population of chronic pain patients before and after a cognitive-behavioural chronic pain management programme. Reliability, validity, and acceptability of each test was examined, and recommendations made for their relative utility.

Physical activity and its relationship to physical performance in patients with end stage knee osteoarthritis.

STUDY DESIGN: Cross-sectional observational design. OBJECTIVES: To compare physical activity levels in men and women with end-stage knee osteoarthritis to those of a comparison group and to examine the relationship between physical activity level and physical performance. BACKGROUND: Osteoarthritis of the knee is associated with significant losses in functional performance and high social costs. Although reductions in physical activity are reported, they have not been quantified or explored. METHODS AND MEASURES: Fifty-nine candidates awaiting total knee arthroplasty (TKAC group) and 79 individuals without osteoarthritis (comparison group) participated. Physical activity was assessed using the Voorrips Questionnaire. Performance measures included fast self-paced walk test, timed up-and-go test, and a timed stair performance measure. A subset of subjects completed the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and underwent muscular strength and endurance testing. The effects of gender and group were tested using GLM ANOVA. Pearson product moment correlations were used to examine relationships between the variables. RESULTS: All aspects of physical activity were lower (P<.001) in the TKAC group, with a moderate difference in household score (18%) and a large difference in leisure activities (63%). Unlike the comparison group, modest but significant correlations (r = 0.31-0.33, P<.03) were observed between overall physical activity and performance test scores for the TKAC group. Physical activity was not significantly related to pain reported on the WOMAC or during the performance tasks. CONCLUSIONS: The belief that pain limits the physical activity of patients with severe osteoarthritis requires further investigation. The profound differences between a comparison group and patients with end-stage osteoarthritis in physical activity have critical implications for the well-being and effective treatment of this population.

Does laxity alter the relationship between strength and physical function in knee osteoarthritis?

OBJECTIVE: Since strengthening interventions have had a lower-than-expected impact on patient function in studies of knee osteoarthritis (OA) and it is known that laxity influences muscle activity, this study examined whether the relationship between strength and function is weaker in the presence of laxity. METHODS: One hundred sixty-four patients with knee OA were studied. Knee OA was defined by the presence of definite osteophytes, and patients had to have at least a little difficulty with knee-requiring activities. Tests were performed to determine quadriceps and hamstring strength, varus-valgus laxity, functional status (Western Ontario and McMaster Universities Osteoarthritis Index Physical Functioning subscale [WOMAC-PF] and chair-stand performance), body mass index, and pain. High and low laxity groups were defined as above and below the sample median, respectively. RESULTS: Strength and chair-stand rates correlated (r = 0.44 to 0.52), as did strength and the WOMAC-PF score (r = -0.21 to -0.36). In multivariate analyses, greater laxity was consistently associated with a weaker relationship between strength (quadriceps or hamstring) and physical functioning (chair-stand rate or WOMAC-PF score). CONCLUSION: Varus-valgus laxity is associated with a decrease in the magnitude of the relationship between strength and physical function in knee OA. In studies examining the functional and structural consequences of resistance exercise in knee OA, stratification of analyses by varus-valgus laxity should be considered. The effect of strengthening interventions in knee OA may be enhanced by consideration of the status of the passive restraint system.

Objectively measuring physical ability in elderly persons: the Physical Capacity Evaluation.

The Physical Capacity Evaluation, a performance measure of functional capabilities comprised of 13 tasks simulating those used in activities of daily living, was tested on 289 community-dwelling elderly people and compared against a widely used self-report measure of function, the Health Assessment Questionnaire. Factor analysis identified one dominant component in each instrument. Internal consistency reliability (Cronbach's alpha) was .90 for both instruments. Global disability (Health Assessment Questionnaire) and function (Physical Capacity Evaluation) scores were correlated -.74. One-week retest reliabilities on 58 subjects were .94 for the Physical Capacity Evaluation and .95 for the Health Assessment Questionnaire. The Physical Capacity Evaluation is a valid and reliable measure of physical performance for use with elderly people.

Does family support buffer the impact of specific chronic diseases on mobility in community-dwelling elderly?

The present study explores whether different structural (presence of partner and children) and functional (amounts of instrumental and emotional support provided by partner and children) family characteristics buffer the influence of chronic diseases on physical functioning. Logistic regression analyses were performed in a population-based sample of 2830 community-dwelling elderly people with chronic diseases as independent variable, and mobility difficulties as dependent variable, for separate strata of family characteristics. The presence of buffer effects was ascertained by comparing the associations between disease variables and mobility difficulties across the strata of family characteristics, using the odds ratios and 95% confidence intervals. Living together with a partner appears to buffer the association between the presence of one chronic disease and mobility difficulties, but no such effect is present among subjects with more than one disease. Regarding specific chronic diseases, partner presence has a beneficial influence only on the association between stroke and mobility difficulties, regardless of whether the partner provides little or much support. For patients with chronic non-specific lung disease (asthma, chronic bronchitis or pulmonary emphysema), a small amount of instrumental support (help with daily chores in and around the house) received from the partner is associated with a higher risk for mobility difficulties, compared to patients who receive a large amount of instrumental support and to patients who are not living with a partner. Neither the presence of children, nor the amounts of support received from them, influences associations between specific chronic diseases and mobility difficulties. The present study provides limited evidence supporting a buffer effect of family characteristics on the association between chronic diseases and mobility. Only in elderly people with a relatively low burden of disease does family support mitigate the adverse effects of disease on physical functioning.
