On loss of activity and independence, adaptation improves life satisfaction in old age : a qualitative study of patients' perceptions

The purpose was to improve the understanding of factors are perceived by elderly people as important for their life satisfaction, during and after rehabilitation. Fifteen persons aged 80–94 years were interviewed while in hospital and on two follow-up occasions after discharge. Assessment of motor function using the General Motor Function assessment scale was used for descriptive purposes. Three themes emerged as important for life satisfaction: activity, independence and adaptation. Activity and independence were considered significant for life satisfaction. Basic activity preferences were related to care of one’s own body and to social contacts. Control and influence over help and services were regarded as important. Different strategies for adaptation to the consequences of disease were used: reorganisation, interaction with caregivers, mental adaptation and mental activities (used as pastime and escape). Those with declined motor functions limited their activity preferences. A key finding was that pleasant past memories were actively recalled in an effort to achieve current life satisfaction. This adaptation strategy created a sense of life satisfaction, however with a potential risk for concealing dissatisfaction with conditions that might otherwise be correctable. Strategies for improving life satisfaction among old people in rehabilitation are suggested.

Continuity of the Self in Later Life: Perceptions of Informal Caregivers

The authors explore perceptions of informal caregivers of extremely elderly (80+) relatives or friends regarding the purpose of caregiving, including factors they considered important for the life satisfaction of the care recipients. They collected data mainly through qualitative interviewed and employed symbolic interactionism. The results revealed a general purpose of the informal caregiving: protection of the care recipient’s self. This purpose was a significant aspect of the identified caregiving categories—social-emotional, proxy, and instrumental care—and the authors consider all four factors important for the care recipients’ life satisfaction: activity, independence, and environmental and adaptive factors. Some informal caregivers gave forceful encouragement to care recipients in an attempt to get them to accept formal care and move to sheltered accommodation. This study underscores the value of informal caregiving and that the caregiving interaction should be balanced by reciprocity.

A longitudinal study of gait function and characteristics of gait disturbance in individuals with Alzheimer's disease.

Walking in daily life places high demands on the interplay between cognitive and motor functions. A well-functioning dual-tasking ability is thus essential for walking safely. The aims were to study longitudinal changes in gait function during single- and dual-tasking over a period of two years among people with initially mild AD (n=21). Data were collected on three occasions, twelve months apart. An optical motion capture system was used for three-dimensional gait analysis. Gait parameters were examined at comfortable gait speed during single-tasking, dual-tasking naming names, and naming animals. The dual-task cost for gait speed was pronounced at baseline (names 26%, animals 35%), and remained so during the study period. A significant (p<0.05) longitudinal decline in gait speed and step length during single- and dual-tasking was observed, whereas double support time, step width and step height showed inconsistent results. Systematic visual examination of the motion capture files revealed that dual-tasking frequently resulted in gait disturbances. Three main characteristics of such disturbances were identified: Temporal disturbance, Spatial disturbance and Instability in single stance. These aberrant gait performances may affect gait stability and increase the risk of falling. Furthermore, the observed gait disturbances can contribute to understanding and explaining previous reported gait variability among individuals with AD. However, the role that dual-task testing and aberrant dual-task gait performance play in the identification of individuals with early signs of cognitive impairment and in predicting fall risk in AD remains to be studied.

Development and reliability of the General Motor Function Assessment Scale (GMF)-A performance-based measure of function-related dependence, pain and insecurity

Purpose : To develop a scale for assessment of three components-dependence, pain and insecurity - related to motor functions of importance for activities of daily living among older rehabilitation patients and to establish its clinical practicality and reliability. Method : A General Motor Function Assessment Scale (GMF) with the above aims was constructed. Clinical practicality was explored by questionnaires to 14 physiotherapists. Inter-rater and test-retest reliability was tested on patients in three different forms of geriatric rehabilitation ( n =20-25) and analysed by percentage agreement (PA) and a non-parametric statistical method, which provide measures of the random disagreement separately from the systematic part of the disagreement. Results : In the clinical test the GMF was found to be time efficient and clinically adequate. Analysis of reliability showed overall high values of PA (PA U 70) and of the rank-order agreement coefficient ( r a >0.82), and low degrees of systematic disagreement. Conclusions : GMF was found to be a clinically useful assessment scale in geriatric rehabilitation. The statistical analyses indicted a high degree of reliability. Comparison of these results with reliability of comparable rating scales is difficult on account of the statistical methods used in other studies, which commonly do not take into account the non-metric properties of the data.

Physical activity and implications on well-being in mild Alzheimer's disease: A qualitative case study on two men with dementia and their spouses

To improve the understanding of experiences of people with mild Alzheimers disease (AD) and their significant others, related to the physical activity of the afflicted persons and its perceived importance. A qualitative case study design was used. The study comprised two men with mild AD and their wives. Data were collected by qualitative interviews and participant observations. Data analysis followed a thematic guideline as described by Braun and Clarke (). Three central themes of experiences related to physical activity in AD were identified: 1) physical activity as health reinforcement; 2) barriers to physical activity; and 3) adaptation strategies. Important motivations for outdoor walks were enjoyable experiences of nature, body movement, and positive attitudes toward physical activity. Several factors were experienced as barriers to physical activity (e.g., tiredness, difficulties in finding ones way, and “peculiar behavior”). Significant others made considerable adjustments in everyday life to enable their partners to retain a physically active lifestyle. The findings indicate that in persons with AD, physical activities such as outdoor walking can play an important part in everyday life by creating meaningful routines and improving experienced well-being and health.

Temporal coordination of the sit-to-walk task in subjects with stroke and in controls.

OBJECTIVES To explore events and describe phases for temporal coordination of the sit-to-walk (STW) task, within a semistandardized set up, in subjects with stroke and matched controls. In addition, to assess variability of STW phase duration and to compare the relative duration of STW phases between the 2 groups. DESIGN Cross-sectional. SETTING Research laboratory. PARTICIPANTS A convenience sample of persons with hemiparesis (n=10; age 50-67y) more than 6 months after stroke and 10 controls matched for sex, age, height, and body mass index. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Relative duration of STW phases, SE of measurement in percentage of the mean, and intraclass correlation coefficients (ICCs). RESULTS Four STW phases were defined: rise preparation, transition, primary gait initiation, and secondary gait initiation. The subjects with stroke needed 54% more time to complete the STW task than the controls did. ICCs ranged from .38 to .66 and .22 to .57 in the stroke and control groups, respectively. SEs of measurement in percentage of the mean values were high, particularly in the transition phase: 54.1% (stroke) and 50.4% (controls). The generalized linear model demonstrated that the relative duration of the transition phase was significantly longer in the stroke group. CONCLUSIONS The present results extend existing knowledge by presenting 4 new phases of temporal coordination of STW, within a semistandardized set-up, in persons with stroke and in controls. The high degree of variability regarding relative STW phase duration was probably a result of both the semistandardized set up and biological variability. The significant difference in the transition phase across the 2 groups requires further study.

Daily Eating Events among Co-living and Single-Living, Diseased Older Men

Objectives: To analyse, describe and compare the frequency and energy intake of eating events, including specific food items, among diseased older men living in ordinary housing.Design: Descriptive and explorative.Setting: Interviews were performed in the participants’ home.Participants: Thirty-five co-living and 26 single-living men, 64–88 years of age. Participants had one of three chronic diseases associated with difficulties in buying and preparing food and with difficulties related to the meal situation: Parkinson’s disease, rheumatoid arthritis or stroke.Measurements: A repeated 24-h recall was used to assess food intake and meal patterns.Results: Eating events were distributed over a 24-h period. Co-living men had a higher (p=0.001) number of eating events/day; both hot and cold eating events were consumed more frequently. There was no difference between groups concerning energy intake. Co-living men more often had hot eating events cooked from raw ingredients (p=0.001) and a greater mix of vegetables/roots (p=0.003) included in such eating events.Conclusion: Single-living men may constitute a vulnerable group from a nutritional perspective, while co-living men, besides the pleasure of eating with another person, seem to get support with food and eating events from their partners. Hence, the group of single-living men, particularly those with a disability, should receive particular attention with regard to possible food-related difficulties.

Declining Physical Capacity But Maintained Aerobic Activity in Early Alzheimer’s Disease

The longitudinal influences on physical capacity and habitual aerobic activity level in the early stages of Alzheimer’s disease (AD) are unclear. Therefore, changes in physical capacity and aerobic activity level were evaluated. Twenty-five individuals with AD were assessed annually for 2 years, by 10-m walk test, 6-minute walk test, and timed up-and-go (TUG) single/dual tasks. Habitual aerobic activity was assessed by diary registrations. The AD group showed a lower physical capacity than controls at baseline but comparable levels of aerobic activity. During the follow-up period, physical capacity declined in the AD group, but the aerobic activity levels changed only marginally. Our results show that in the early stages of AD, people are capable of maintaining health-promoting aerobic activity levels, despite a decline in their physical capacity. Additionally, it appears that cognitive dysfunction contributes to an impaired physical capacity. The TUG tasks might, therefore, be useful for detecting early signs of cognitive impairment.

Impact of stroke on anterior–posterior force generation prior to seat-off during sit-to-walk

Force generation during sit-to-walk (STW) post-stroke is a poorly studied area, although STW is a common daily transfer giving rise to a risk of falling in persons with disability. The purpose of this study was to describe and compare strategies for anterior-posterior (AP) force generation prior to seat-off during the STW transfer in both subjects with stroke and in matched controls. During STW at self-selected speed, AP force data were collected by 4 force plates, beneath the buttocks and feet from eight subjects with stroke (>6 months after onset) and 8 matched controls. Subjects with post-stroke hemiparesis and matched controls generated a similar magnitude of total AP force impulses (F(1,71)=0.67; p=0.42) beneath buttocks and feet prior to seat-off during STW. However, there were significant group differences in AP force impulse generation beneath the stance buttock (i.e. the non-paretic buttock in the stroke group), with longer duration (F(1,71)=8.78; p<0.005), larger net AP impulse (F(1,71)=6.76; p<0.05) and larger braking impulse (F(1,71)=7.24; p<0.05) in the stroke group. The total braking impulse beneath buttocks and feet was about 4.5 times larger in the stroke group than in the control group (F(1,71)=8.84; p<0.005). An intra- and inter-limb dys-coordination with substantial use of braking impulses was demonstrated in the stroke group. This motor strategy differed markedly from the smooth force interaction in the control group. These results might be important in the development of treatment models related to locomotion post-stroke.

The Vitality, Independence, and Vigor in the Elderly 2 Study (VIVE2): Design and methods

BACKGROUND Nutritional supplementation may potentiate the increase in skeletal muscle protein synthesis following exercise in healthy older individuals. Whether exercise and nutrition act synergistically to produce sustained changes in physical functioning and body composition has not been well studied, particularly in mobility-limited older adults. METHODS The VIVE2 study was a multi-center, randomized controlled trial, conducted in the United States and Sweden. This study was designed to compare the effects of a 6-month intervention with a once daily, experimental, 4 fl.oz. liquid nutritional supplement providing 150 kcal, whey protein (20 g), and vitamin D (800 IU) (Nestlé Health Science, Vevey, Switzerland), to a low calorie placebo drink (30 kcal, non-nutritive; identical format) when combined with group-based exercise in 150 community-dwelling, mobility-limited older adults. All participants participated in a structured exercise program (3 sessions/week for 6 months), which included aerobic, strength, flexibility, and balance exercises. RESULTS The primary outcome was 6-month change in 400 m walk performance (m/s) between supplement and placebo groups. Secondary outcomes included 6 month change in: body composition, muscle cross-sectional area, leg strength, grip strength, stair climb time, quality of life, physical performance, mood/depressive symptoms and nutritional status. These outcomes were selected based on their applicability to the health and well-being of older adults. CONCLUSIONS The results of this study will further define the role of nutritional supplementation on physical functioning and restoration of skeletal muscle mass in older adults. Additionally, these results will help refine the current physical activity and nutritional recommendations for mobility-limited older adults.
