Differences in awareness between persons with left and right hemispheric stroke

Abstract

Aim: The aim of this study was to investigate whether there are any differences in awareness of ability between persons with left and right hemispheric stroke. Methods: The sample consisted of data from the Assessment of Awareness of Ability (A³) database, primarily consisting of clients admitted to occupational therapy services. In total the study included 183 data records from clients, 78 with left and 105 with right hemispheric stroke. Awareness of ability was assessed using the Assessment of Awareness of Ability (A³). Differences in awareness were investigated using t-tests, CI, effect size, and differential item functioning. Results: No significant overall mean difference (t-test = 1.31, p = 0.19) in awareness between left and right hemispheric stroke was identified. However, significant differences (p < 0.05) were identified on three specific items included in the A³. In these cases, persons with right hemispheric stroke showed a more limited awareness. Conclusion: Persons with right hemispheric stroke have more pronounced problems with being aware of limitations in specific ADL performance skills compared with persons with left hemispheric stroke.     

On Functions,Abilities and Quality of Life After Subarachnoid Haemorrhage: Occupational Therapy Aspects

This investigation addresses functions/impairments, abilities/disabilities and quality of life (QoL) in a consequtive series of non-hospitalized long-term survivors [2, 5–12 years] of subarachnoid haemorrhage (SAH). The investigated parameters of functions/impairments were: motor, language, perceptual and memory functions. Abilities/disabilities studied were: activities of daily living (ADL) including both personal- and instrumental ADL, working and leisure capacities. Quality of life was assessed using a double visual analogue scale. Occurrence of depression was registered using a self-rating scale.

A questionnaire focusing motor and language impairments, personal ADL, work and leisure activities was initially mailed to 324 subjects. Most of them answered the questionnaire. Ten hospitalized subjects could not validly report their functions and abilities and for that reason were excluded.

In a follow-up investigation up to 247 long-term non-hospitalized subjects were investigated by a physician and an occupational therapist. A total of 82% had at least one impairment. The majority (73%) had memory impairment and among these subjects equal proportions (about 50%) had impairments of long-and short-term memory. Forty-five percent were perceptually impaired, while motor impairment occurred for 25% and aphasia in 10%. Only a small minority (9%) were, according to self-reports, regarded as being to some extent disabled in personal ADL. The corresponding numbers of disabled in instrumental ADL, leisure and working-capacity were 52%, 48% and 40% respectively. Depression was found in 22%—among whom the majority had minimal or mild depression. Overall QoL was judged to be unchanged or increased in 62% of cases and, therefore, decreased in 38%.

As expected, impairments to a significant degree caused disabilities. None of the five different categories of impairment were associated with mood (depressed/not depressed) and QoL (decreased/not decreased). Occurrence of depression was significantly associated with the different aspects of disabilities. In contrast, among a series of instrumental ADL-variables, leisure and working capacity, QoL was influenced negatively only by decreased ability to act sociably and, to a minor extent, by depressed mood.

Judging from the extent of decreased quality of life, it appears that nearly 40% of all non-hospitalized former victims of SAH have not coped successfully with the impact of the SAH. A follow-up programme aiming at optimizing the coping process of SAH victims is, therefore, outlined     

The anti-arthritic activity of total glycosides from Pterocephalus hookeri,a traditional Tibetan herbal medicine

Context: Pterocephalus hookeri (C. B. Clarke) Hock., a traditional Tibetan herbal medicine rich in glycosides, has been used to treat several diseases including rheumatoid arthritis.

Objective: To evaluate the anti-arthritic activity of total glycosides from P. hookeri, and its possible mechanisms of action.

Materials and methods: Anti-arthritic activity of total glycosides from P. hookeri (oral administration for 30 days at 14–56?mg/kg) was evaluated using paw swelling, arthritis scores and histopathological measurement in adjuvant-induced arthritis (AA) Sprague-Dawley rats. The NF-κB p65 expression in synovial tissues, and serum superoxide dismutase (SOD) activity, malondialdehyde (MDA) and nitric oxide (NO) levels was measured in AA rats, respectively. Further assessment of anti-inflammatory and analgesic activities of these glycosides were carried out using inflammation and hyperalgesia models induced by xylene, carrageenan, agar and acetic acid, respectively.

Results: Total glycosides (56?mg/kg) decreased the paw swelling (38.0%, p?p?p?p?p?p?p?Discussion and conclusion: Our findings confirmed the anti-arthritic property of the total glycosides from P. hookeri, which may be attributed to its inhibition on NF-κB signalling and oxidative stress.     

Participation in the Chronic Phase of Stroke

Abstract

Background: Participation is a multidimensional concept, consisting of an objective and a subjective dimension. Many studies have focused on determinants of only 1 dimension of participation post stroke. Objective: To describe participation (both objective and subjective) and to determine how physical and cognitive independence and subjective complaints (pain, fatigue, and mood) influence participation in community-dwelling stroke survivors in the Netherlands. Methods: The Utrecht Scale for Evaluation of Rehabilitation (USER) measures physical and cognitive independence and subjective complaints. USER-Participation measures 3 dimensions of participation: frequency (objective perspective), restrictions (subjective perspective), and satisfaction (subjective perspective). Spearman correlations and backward linear regression analyses were used to analyze associations between the 3 USER-Participation scores with demographics, stroke characteristics, physical and cognitive independence, and subjective complaints. Results: Of the 111 participants, 48.5% returned to work post stroke, but mostly for only 1 to 16 hours a week. Experienced participation restrictions were most prevalent in physical exercise, chores in/around the house, housekeeping, and outdoor activities. On average, participants were relatively satisfied with their participation, but dissatisfaction occurred in cognition, activities outdoors, and work/housekeeping. Regression analysis revealed that objective participation was determined by physical and cognitive independence, age, and education, whereas subjective participation was determined by physical and cognitive independence, fatigue, and mood. Conclusions: Most participants experienced participation problems, despite relatively good physical recovery. In addition to physical and cognitive factors, subjective complaints of persons with stroke should be addressed in the rehabilitation program.     

Medication Use in Alzheimer's Disease and Healthy Aging

Abstract

The purpose of this research was to determine if decreased utilization of specific medication in individuals with Alzheimer's disease (AD) reflects a global process of decreased medication usage. Participants were 1103 individuals (461 controls; 437 probable AD; 161 possible AD, and 44 Mixed Dementia), drawn from our Alzheimer's Disease Research Registry. Medication usage at entry into the registry did not differ between controls and probable AD cases. Possible AD and the mixed dementia cases took significantly more medications than controls or probable AD cases. Longitudinal analysis showed no significant changes in controls and mixed dementia cases up to 2 years, and use increased in possible and probable AD cases over time. Stratification of subjects by MMSE scores at entry showed no significant difference between groups. Medication use in probable AD patients does not differ from controls, and does not seem to be subject to systematic bias based on disease progression (as measured by MMSE scores). The presence of co-morbidity adds to medication utilization. Cognitive impairment does not appear to affect total medication use, suggesting that specific medication utilization patterns are unlikely to be the result of larger usage patterns.

Consistency of gait characteristics as determined from acceleration data collected at different trunk locations

Estimates of gait characteristics may suffer from errors due to discrepancies in accelerometer location. This is particularly problematic for gait measurements in daily life settings, where consistent sensor positioning is difficult to achieve. To address this problem, we equipped 21 healthy adults with tri-axial accelerometers (DynaPort MiniMod, McRoberts) at the mid and lower lumbar spine and anterior superior iliac spine (L2, L5 and ASIS) while continuously walking outdoors back and forth (20 times) over a distance of 20 m, including turns. We compared 35 gait characteristics between sensor locations by absolute agreement intra-class correlations (2, 1; ICC). We repeated these analyses after applying a new method for off-line sensor realignment providing a unique definition of the vertical and, by symmetry optimization, the two horizontal axes. Agreement between L2 and L5 after realignment was excellent (ICC > 0.9) for stride time and frequency, speed and their corresponding variability and good (ICC > 0.7) for stride regularity, movement intensity, gait symmetry and smoothness and for local dynamic stability. ICC values benefited from sensor realignment. Agreement between ASIS and the lumbar locations was less strong, in particular for gait characteristics like symmetry, smoothness, and local dynamic stability (ICC generally < 0.7). Unfortunately, this lumbar-ASIS agreement did not benefit consistently from sensor realignment. Our findings show that gait characteristics are robust against limited repositioning error of sensors at the lumbar spine, in particular if our off-line realignment is applied. However, larger positioning differences (from lumbar positions to ASIS) yield less consistent estimates and should hence be avoided.     

EDITORIAL

There is a growing literature that seeks to evaluate the role of “recovery capital” in the resolution of substance use disorders. In this study, a structured instrument (the Assessment of Recovery Capital), along with an assessment of social networks among 176 former illicit drug users and drinkers, is measured in three locations in England. There were relationships between recovery capital and vocational activity (training or employment), physical health, psychological health, and overall quality of life, with larger social networks associated with enhanced personal and social recovery capital. The study demonstrates high levels of personal and social well-being—manifesting in engagement in community activities and strong social networks—among persons engaged in recovery support activities that was not linked to time in recovery.
