The Purdue Pegboard Test: Normative data for people aged 60 and over

Manual dexterity is frequently evaluated in rehabilitation services to estimate hand function. Several tests have been developed for this purpose, including the Purdue Pegboard, which measures fine manual dexterity. The goals of the study were to verify the test-retest reliability with subjects aged 60 and over without upper limb impairment, and to develop normative data based on a random sample of healthy older community-living individuals. The results show that the test-retest reliability is good (intra-class correlation coefficients from 0.66 to 0.90, depending on the subtest). Norms are presented to help clinicians involved in rehabilitation services to better differentiate real dexterity deficits from those that may be attributed to normal ageing.

Measuring social participation: reliability of the LIFE-H in older adults with disabilities

Purpose: Much more attention should be paid to instruments documenting social participation as this area is increasingly considered a pivotal outcome of a successful rehabilitation. The purpose of this study was to document the reliability of a participation measure, the Assessment of Life Habits (LIFE-H), in older adults with functional limitations. Methods: Eighty-four individuals with physical disabilities living in three different environments were assessed twice with the LIFE-H, an instrument that documents the quality of social participation by assessing a persons performance in daily activities and social roles (life habits). Results: The intraclass correlation coefficients (ICC) computed for intrarater reliability exceeded 0.75 for seven out of the 10 life habits categories. For interrater reliability, the total score and daily activities subscore are highly reliable (ICC ⩽ 0.89), and the social roles subscore is moderately reliable (ICC = 0.64). ‘Personal care’ is the category with the highest ICC, and for five other categories ICCs are moderate to high (< 0.60). Conclusion: LIFE-H is a valuable addition to instruments that mostly emphasize the concepts of function or functional independence. It is particularly meaningful to evaluate the participation of older adults in significant social role domains such as recreation and community life. It may be considered among the instruments having the best fit with the ICF definition of participation (the persons involvement in a life situation) and a majority of its related domains.

Performance of the ‘Unaffected’ Upper Extremity of Elderly Stroke Patients

BACKGROUND AND PURPOSE The main objective of this study was to compare the sensorimotor performance of the unaffected upper extremity (UE) of elderly stroke patients with that of healthy elderly people. METHODS The group of stroke patients was composed of 43 hemiplegic/paretic subjects who had had a cerebrovascular accident at least 6 months earlier. They were > or = 60 years old, were right-handed before the stroke, had visual perception within normal limits, and showed no major cognitive impairments. A group of 43 healthy subjects matched for dominance, age, and sex was used for comparison. The main parameters of the performance of the unaffected UE of the stroke subjects and of the same side of the healthy subjects were measured with valid, reliable instruments. Some variables potentially related to the unaffected UE were also measured: affected UE motor function, functional independence, length of time since the stroke, self-perceived health status, activity level, and hand anthropometry. RESULTS Statistical analyses showed significant deficits in the unaffected UE of hemiplegic/paretic subjects compared with normal subjects with regard to the following parameters: gross manual dexterity, fine manual dexterity, motor coordination, global performance, and kinesthesia (P < .01 to P < .0001). No significant clinical or statistical difference was found for grip strength (P < .81), static and moving two-point discrimination (P = .21 and P = .12), or touch/pressure threshold (P < .91). CONCLUSIONS Many factors (frequency of use of the unaffected hand, sensorimotor interaction tasks, severity of the deficits in corticifugal projections, and deficits in postural stabilization) could interact to provide the clinical picture obtained in the present study.

Predictors of handicap situations following post-stroke rehabilitation.

Purpose : Many stroke survivors have to cope with impairments and disabilities that may result in the occurrence of handicap situations. The purpose of the study was to explore bio-psycho-social predictors of handicap situations six months after discharge from an intensive rehabilitation programme. Methods : At discharge from a rehabilitation programme, participants were evaluated with instruments measuring motor, sensory, cognitive, perceptual, affective and psychosocial impairments and disabilities that may play a role in the development of handicap. Some other demographic and clinical variables, and those related to rehabilitation, were also collected. Six months later, they were re-assessed in their own environment in order to document their handicap level with the Assessment of Life Habits (LIFE-H). Results : One hundred and thirty-two stroke patients participated in the discharge evaluation and 102 of them also participated in the handicap measurement. Relationships between handicap level and impairments and disabilities were all statistically significant. Multiple regression analyses indicated that affect, lower extremity co-ordination, length of stay in rehabilitation, balance, age and comorbidity at the end of an intensive rehabilitation programme are the best predictors of handicap situations six months later (adjusted R 2 : 68.1%). Conclusions : In spite of its exploratory nature, this study revealed that, among a substantial number of personal characteristics, some were more related to a handicap measure and have greater predictive value. Other studies should be carried out to validate these findings and to consider more environmental factors in order to better understand factors related to the development of handicap situations.

Is social participation associated with quality of life of older adults with physical disabilities

Purpose: To explore the relationships between subjective quality of life and social participation of older adults with physical disabilities. Method: A cross-sectional design was used with a convenience sample of 46 people aged 60 to 90 living in the community. Subjective quality of life was estimated with the Quality of Life Index and social participation with the Assessment of Life Habits. Results: Only a weak relationship was found between total scores of quality of life and social participation. Interpersonal relationships, responsibilities, fitness and recreation were the categories of social participation most associated with quality of life. Social roles were more associated with quality of life than daily activities. Finally, satisfaction with the accomplishment of life habits was also more associated with quality of life than the performance itself. Conclusions: The importance of social participation in regard to the quality of life of older persons with physical disabilities living in the community is partially supported by these findings. Other studies are needed to clarify how social participation influences quality of life in this population.

Development of a conceptual framework of positive aspects of caregiving in dementia

Research on family caregivers usually focuses more on stress and burden, especially in the context of looking after a person with dementia. This leads to fewer considerations of positive aspects of caregiving. Thus enhancing these positive aspects represents an innovative approach to caregivers’ support. Furthermore, these aspects need more conceptualization to underpin the development of such an approach. This article proposes a conceptual framework of the positive aspects of caregiving based on an integrative literature review. This conceptual framework provides a comprehensive model that should improve understanding of positive aspects of caregiving. It could also contribute to the development of innovative support programs based on the positive aspects instead of the negative aspects of caregiving.

Training Mobility Tasks after Stroke with Combined Mental and Physical Practice: A Feasibility Study

This study examines the potential of using mental practice (MP) to promote the learning of 2 mobility tasks in persons with stroke. Twelve patients were trained with MP to increase the loading of the affected limb while standing up from a chair and sitting down. Vertical forces were recorded using force plates under each foot and the chair. Changes in the loading of the affected limb and in task duration, immediately after 1 training session and 24 h later, served as outcomes. After training, the loading of the affected limb had increased {P < 0.001) during standing up (16.2%) and sitting down (17.9%), and the improvement remained significant 24 h later, indicating a learning effect. In contrast, the duration of the performance did not change with training. The results indicate that, in the early stage of learning with MP, changes in limb-loading strategies are a more sensitive measure of performance than is speed.

Development and Reliability of an Upper Extremity Function Test for the Elderly: The TEMPA

Accurate assessment of upper extremity performance is a critical element in determinimg the potential independance of the physically impaired person. An upper extremity function test for the elderly, the TEMPA (Test Évaluant les Membres supérieurs des Personnes Âgées), was developed, involving nine tasks related to routine daily activities. Each task is measured by three sub-scores: speed of execution, functional rating and task analysis. A test-retest and interrater reliability study was conducted with a sample of 29 subjects, aged 62 to 82 years, with various upper extremity impairments and varying degrees of functional independance. Intraclass correlation coefficients ranged from moderate to high (0.70 to 1.0), demonstrating temporal stability and sound agreement between evaluators. A preliminary construct validity study was conducted by correlating score of the TEMPA with functional independance to basic personal care (Spearmans Rho = 0.74). The TEMPA is a reliable instrument that appears to fill a void in the evaluation of the elderly. More psychometric studies are required to confirm its validity.

Association between personal and environmental factors and the occurrence of handicap situations following a stroke

Background and purpose : Little is known about the potential role of environmental factors in the handicap creation process following a stroke. The objective of this study was to explore the presence of a relationship between environmental factors and the occurrence of handicap following a stroke, taking into consideration age and the level of impairments and disabilities. Methods : This is a cross-sectional study where data were collected 6 months after discharge from an intensive functional rehabilitation unit. A convenience sample of 51 participants was recruited at the time of their admission to the rehabilitation unit for rehabilitation post-stroke. Perceived influence of environmental factors was measured using the Measure of the Quality of the Environment (MQE). Handicap situations were measured with the Assessment of Life Habits (LIFE-H). Impairments and disabilities comprised six domains (cognition, perception, depression, communication, sensorimotor function and comorbidity) assessed using a variety of measuring tools from which a composite score was derived. Results : Fifty-one participants aged 40-97 years old took part in this study. Perceived obstacles in the environment, together with age and the level of impairments and disabilities, explained 58.9% of the variation in the LIFE-H (handicap level). Taken alone, the perceived obstacles (total score) explained 6.2%. The perceived facilitators (total score) in the environment were not found to be related to the presence of handicap situations. Conclusion : Increased level of impairments and disabilities, advanced age and perceived barriers in the physical and social environment contribute to the handicap creation process following a stroke.BACKGROUND AND PURPOSE Little is known about the potential role of environmental factors in the handicap creation process following a stroke.

Average grip strength: A meta-analysis of data obtained with a Jamar dynamometer from individuals 75 years or more of age

Background and Purpose: Although strength diminishes with age, average values for grip strength have not been available heretofore for discrete strata after 75 years. The purpose of this meta‐analysis was to provide average values for the left and right hands of men and women 75–79, 80–84, 85–89, and 90–99 years. Methods: Contributing to the analysis were 7 studies and 739 subjects with whom the Jamar dynamometer and standard procedures were employed. Results: Based on the analysis, average values for the left and right hands of men and women in each age stratum were derived. Conclusions: The derived values can serve as a standard of comparison for individual patients. An individual whose grip strength is below the lower limit of the confidence intervals of each stratum can be confidently considered to have less than average grip strength.
