Effect of activity-based mirror therapy on lower limb motor-recovery and gait in stroke: A randomised controlled trial

Objective: To determine the effect of activity-based mirror therapy (MT) on motor recovery and gait in chronic poststroke hemiparetic subjects.

Design: A randomised, controlled, assessor-blinded trial.

Setting: Rehabilitation institute.

Participants: Thirty-six chronic poststroke (15.89?±?9.01 months) hemiparetic subjects (age: 46.44?±?7.89 years, 30 men and functional ambulation classification of median level 3).

Interventions: Activity-based MT comprised movements such as ball-rolling, rocker-board, and pedalling. The activities were provided on the less-affected side in front of the mirror while hiding the affected limb. The movement of the less-affected lower limb was projected as over the affected limb. Conventional motor therapy based on neurophysiological approaches was also provided to the experimental group. The control group received only conventional management.

Main outcome measures: Brunnstrom recovery stages (BRS), Fugl-Meyer assessment lower extremity (FMA-LE), Rivermead visual gait assessment (RVGA), and 10-metre walk test (10-MWT).

Results: Postintervention, the experimental group exhibited significant and favourable changes for FMA-LE (mean difference?=?3.29, 95% CI?=?1.23–5.35, p?=?.003) and RVGA (mean difference?=?5.41, 95% CI?=?1.12–9.71, p?=?.015) in comparison to the control group. No considerable changes were observed on 10-MWT.

Conclusions: Activity-based MT facilitates motor recovery of the lower limb as well as reduces gait deviations among chronic poststroke hemiparetic subjects.     

Parental characteristics and the risk of schizophrenia in a Chinese population: a case-control study

Background: Genetic studies have provided convergent results indicating that schizophrenia is a polygenic disorder with a heritability estimate of ～60–80%. The propensity for schizophrenia is ～10 times higher in individuals with first-degree relatives with schizophrenia when compared to the general population.

Aim: To identify associations between parental characteristics and the risk of schizophrenia in a Chinese population.

Methods: Participants with a diagnosis of schizophrenia were recruited along with healthy controls (HCs) matched for age and gender from Weifang, China. Logistic regression models and generalized linear models were used to explore the associations between parental characteristics with the risk and age at onset of schizophrenia. In total, 414 cases and 639 HCs were recruited for the study.

Results: We observed an inverse association between levels of paternal and maternal education and risk of schizophrenia after controlling for potential confounders (Paternal: OR?=?1.525, 95% CI: 1.080–2.153, p?=?.017; Maternal: OR?=?1.984, 95% CI: 1.346-2.924, p?=?.001). Younger paternal and maternal childbearing age were associated with a higher risk of diagnosis of schizophrenia. We furtherly observed that individuals with earlier age at onset of schizophrenia had fewer siblings (p?=?.007) and had higher rates of parental marital disharmony (p?=?.033).

Conclusion: Our results indicate that parental years of education and age of childbearing are associated with an increased risk of schizophrenia in a Chinese population. Age of onset of schizophrenia was positively associated with a greater number of siblings and negatively associated with parental marital disharmony.     

Exploring dimensions of social support and resilience when providing care at the end of life: a qualitative study

Background: Research shows that formal and informal social support can facilitate resilience in carers. There is a paucity of research exploring social support and resilience amongst recently bereaved informal carers.

Aim: To examine how the presence or absence of distinct dimensions of social support facilitate or hinder resilience in recently bereaved informal carers.

Participants: 44 bereaved carers, who had been identified by GP as ‘main carer’ of someone recently deceased (3–12 months), aged between 38 and 87 years old (mean= 67).

Methods: Thematic analysis then the Ecological Framework of Resilience as an organisational tool to develop overarching themes in the data. We used the Sherbourne and Stewart model to identify social support that was lacking as well as social support that was present.

Results: A range of social support types were identified. There was an emphasis on the importance of relationships with both health professionals and family members, including the care recipient. However, social support was not necessary for resilience if the participant had other resources.

Conclusions: Social support for carers providing end of life care is almost exclusively based around end of life care ‘work’. In comparison to other research our study suggests that relationships with family and health professionals are paramount. Multidimensional support is needed for carers to enhance their resilience.     

Measuring abnormal intrinsic brain activities in patients with retinal detachment using amplitude of low-frequency fluctuation: a resting-state fMRI study

Objective: The targets of this study were to access the alternations of spontaneous brain activity in RD patients by amplitude of low-frequency fluctuation (ALFF) method and to explore their relationships with clinical behavioral performance.

Methods: A total of 20 patients with RD (6 males and 14 females), and 20 healthy controls (HCs) (6 males and 14 females) were recruited, and were matched in sex and age. All participants finished the functional magnetic resonance imaging (fMRI) scanning. We applied the ALFF method to detect the spontaneous brain activity. Receiver operating characteristic (ROC) curve was applied to distinguish RD Patients from HCs.

Results: RD patients showed decreased ALFF values in the right occipital lobe and right medial frontal gyrus and increased ALFF values in the right frontal superior orbital and left inferior temporal gyrus when compared with HCs. In RD patients, we did not find any relationship between the mean ALFF values and the clinical behavioral performances.

Conclusion: The RD patients exhibited abnormal spontaneous brain activity in vision and vision related brain regions, which might explore potential pathological mechanism of acute vision loss in RD patients.     

Pharmacogenetics and levodopa induced motor complications

Aim: L-dopa remains the most effective symptomatic therapy for Parkinson's disease (PD) but unfortunately, its chronic use is often associated with motor complications. This review highlights the importance of pharmacogenetics in an individualised PD therapeutic approach.

Material and Methods: review of the literature was done.

Results: PD patients show remarkable heterogeneity in their response to L-dopa and this profound interindividual heterogeneity suggests that there is a genetic predisposition.

Conclusions: The impact of the genetic makeup of every individual on PD treatment appears to be of great importance in order to achieve not only the optimum therapeutic effect, but also with minimal side effects.     

French translation and validation of a fragile X syndrome screening checklist

Background: Fragile X syndrome (FXS) is the most common cause of inherited intellectual disability among men. This syndrome is frequently underdiagnosed in adults. The aim of this study was to develop and validate a French translation of the screening checklist Fragiele-X screeningslijst.

Method: The validation sample for the translated checklist included 22 pairs of men between the ages of 18 and 52, matched by age and degree of intellectual impairment.

Results: The translated checklist achieved coefficients of 0.92 for internal consistency, 0.90 for test-retest reliability and 0.65 for inter-rater reliability. These psychometric properties are commensurate with those of the original checklist.

Conclusion: Therefore, the translated checklist developed in this study can be considered a valid screening instrument for the detection of FXS in men with intellectual disabilities.

Abbreviations: FXS: fragile X syndrome; FMR1: fragile X mental retardation 1 (gene)     

Validity and reliability of fatigue severity scale in stroke

Background: Fatigue is a frequent complaint after stroke and may be associated with dependence in activities of daily living, decreased quality of life, increased institutionalization and mortality. Although fatigue severity scale (FSS) is the most frequently used scale in stroke, validation studies are scarce.

Objectives: This study aimed to examine the psychometric properties of FSS in subjects with stroke.

Methods: A total of 46 subjects with stroke who were admitted for rehabilitation and 52 control subjects who were admitted for local musculoskeletal problems were included. A comprehensive assessment including functional independence measure, Folstein Mini-Mental State Examination, Hospital Anxiety and Depression Scale (HADS), visual analog scale for fatigue (VAS), FSS, and vitality subscale of 36-item Medical Outcomes Study Short-Form Health Survey (SF-36v) was conducted. FSS, VAS and SF-36v were repeated 7 days later.

Results: FSS demonstrated excellent internal consistency in subjects with stroke (Cronbach’s alpha: 0.928). There was a moderate correlation between FSS and SF-36v (r = ?0.498, p < 0.001). FSS was weakly correlated with HADS anxiety (r = 0.310, p = 0.041) and HADS depression (r = 0.334, p = 0.027). Test-retest reliability of SF-36v (ICC: 0. 746, CI: 0.518–0.866), VAS (ICC: 0.829, CI: 0.671–0.911) and FSS (ICC: 0.742, CI: 0.512–0.863, p < 0.001) was good. ICC values for individual items of FSS were good except for item 6.

Conclusions: FSS is a valid and reliable scale to measure fatigue in stroke. FSS is not sensitive to differentiate fatigue in stroke from the control subjects with orthopedic problems with similar age and gender.

Main contribution: A review of the literature, with examples of practical applications.

Conclusions: The work of Professor Worrall has greatly influenced the field of aphasia; her legacy is the research capacity she has built in Australia and around the world.     

A Note on the “One Case per Stagger Position” Character of Common Multiple-Baseline Intervention Designs

Purpose: To overcome the constraint of common multiple-baseline designs that only one case per stagger position is permitted.

Methods: Three alternative strategies for assigning more than one case to each stagger position are examined.

Results: The three recommended strategies achieve the objective while maintaining the study’s internal and statistical-conclusion validities.

Conclusions: ExPRT, a freely available Excel-based randomization-test package, can be used to assist in both the design and statistical analysis associated with each of the strategies.     

Estimation of skeletal muscle mass in patients with spinocerebellar ataxia type 3 and 10

Background: Neurodegenerative diseases may progress to a level in which patients present spontaneous weight loss, resulting in increased falls and functional disabilities when the disease is associated with muscle mass depletion.

Objective: Evaluate the muscle compartment in patients presenting spinocerebellar ataxia (SCA) type 3 and 10.

Methods: Forty-six patients presenting SCA type 3 and 10 were assessed and 76 volunteers were selected to the control group. In order to evaluate the muscle compartment, muscle mass anthropometric measurements were assessed and total skeletal muscle mass calculated through a predictive equation.

Results: Women with SCA3 presented greater weight loss and muscle mass reduction compared to those with SCA10 and the control group. Among the predictive measurements, calf muscle circumference showed a more significant correlation with total skeletal muscle mass (p = 0.718).

Conclusion: Patients presenting both types of ataxia did not show severe depletion in their nutritional status; however, those with SCA3 displayed greater weight loss and muscle mass reduction compared to the SCA10 group.     

Acute aseptic meningitis during isotretinoin treatment for nodular acne solely presenting with headache: case report and brief review of the literature

Purpose/aim: We describe, in detail, the first case of isotretinoin-induced aseptic meningitis. A brief summary of the literature on drug-induced aseptic meningitis (DIAM) is also presented.

Materials and methods: A 20-year old female patient with probable (Naranjo adverse reaction probability score of 7) DIAM during treatment with isotretinoin therapy for nodular acne solely, presenting with headache. Pseudotumor cerebri was appropriately ruled-out.

Results: Summary of data altogether lead us suggest that isotretinoin triggered DIAM, possible due to a delayed hypersensitivity mechanism type III or IV.

Conclusion: We highlight a quite uncommon cause of DIAM that may be increasing in frequency due to the current increasing use of isotretinoin against nodular acne.     

Recall of emotional and neutral words and paragraphs in traumatic brain injury

Background: Traumatic brain injury (TBI) results in verbal recall deficits and impaired processing of emotion encoded in facial appearance, prosody and the linguistic content of messages. Emotion facilitates memory (emotional memory advantage) for non-brain injured (NBI) individuals but the impact of emotion on verbal recall for linguistically encoded stimuli in TBI has not been explored.

Aims: The purpose of this study was to determine the effects of stimulus emotional content on verbal recall of words and paragraphs in TBI compared to NBI individuals.

Methods and procedures: Six 10-item lists, each with five emotional and five neutral words, and six paragraphs (three emotional, three neutral) were counterbalanced and presented in random order to 20 individuals with TBI and 44 NBI. The number of words from lists and the number of content units from paragraphs were compared for the two groups.

Outcomes and results: The NBI participants recalled more words from the lists and content units from the paragraphs than the individuals with TBI. Both groups recalled significantly more emotional than neutral words. NBI but not TBI participants had significantly greater recall for information in paragraphs with emotional content.

Conclusions: Participants with TBI showed impaired recall of words and paragraph content. Emotion facilitated word and paragraph content recall for neurotypical individuals but emotional memory advantage was limited to words for the TBI participants.     

An international survey of obesity and underweight in youth and adults with intellectual disabilities

Background: Increased levels of obesity have been reported for people with intellectual disability based on data mostly gathered in high income countries. Likewise few studies internationally have focussed on underweight in this population.

Method: Data on obesity and underweight were analysed from nearly 86,500 youth and adults with intellectual disabilities drawn from 178 countries attending Special Olympic events.

Results: Binary logistic regressions identified higher levels of obesity for athletes in high income countries – especially in North America – and for females and for adults aged 40 years and over; and for youth aged 8 to 10 years. Rates of underweight were higher for younger adults in low income countries of Asia-Pacific, and highest for males aged 11-13 from lower-middle income countries of Africa.

Conclusions: Contrasting intervention strategies are needed globally to enable people with intellectual disabilities to achieve healthy weight.     

Factors affecting rehabilitation and use of upper limb after stroke: views from healthcare professionals and stroke survivors

Background: Training of the upper limb (UL) is limited in stroke rehabilitation, and about 50% of stroke survivors do not regain useful function in their upper limb.

Objectives: This study explored what factors affect rehabilitation and use of upper limb after stroke from a stroke survivor and healthcare professional perspective to better understand low engagement in UL rehabilitation in the chronic stages of stroke.

Method: Eight chronic stroke survivors and 21 healthcare professionals took part in semi-structured interviews or in one of three focus groups, respectively.

Results: Thematic analysis revealed three main themes: Availability of resources, Healthcare professional–patient relationship, and Psychosocial factors. Availability of resources and Healthcare professional–patient relationship indicated that due to resource pressures and a lack of communication and education, positive upper limb rehabilitation behaviors (e.g. engaging and integrating the upper limb in daily activity) were not always established in the early stages post-stroke. Psychosocial factors illustrated the cognitive and psychological barriers to sustained engagement with upper limb rehabilitation.

Conclusion: The findings indicate that stroke survivors and healthcare professionals have very similar understandings of barriers to UL activity, and positive upper limb rehabilitation behaviors are not always established early in recovery post-stroke. Increased resources and healthcare professional–patient relationships seem key factors to establishing positive perceptions of UL rehabilitation. Addressing psychosocial issues and resource limitations may help sustain engagement with UL rehabilitation.     

Predictors of maternal stress in pre-school and school-aged children with autism

Background: Mothers of children with autism experience high levels of stress. However, little is known about whether maternal stressors differ across children of different ages.

Method: This study investigated stressors in mothers of 29 pre-school-aged and 27 school-aged children with autism. Correlation and regression analyses were used to determine if maternal stressors differed between the two age groups.

Results: Findings revealed no difference in maternal stress levels across the two age groups; however, stressors for each age group were different. Stressors in the school-aged group were related to repetitive behaviours, sensory sensitivities, and problematic behaviours, while stressors in the pre-school-aged group were mainly related to adaptive behaviours.

Conclusions: These findings are informative for practitioners and highlight the need for tailored supports and therapies for mothers of children with autism of different ages.     

Effects of aging on the myelination of the optic nerve in rats

Aim of the study: Cognitive decline due to aging is most probably the result of changes in the white matter in the central nervous system (CNS) and/or demyelination.

Material and methods: We used electron microscopic analysis of the morphological changes in aging rats’ optic nerves as an easily accessible part of the CNS.

Results: Several age changes were observed in aging rats (36?months) vs. young adult rats (6?months), namely degeneration of axons, decreased packing density and morphological alterations of myelination, including the ballooning of some myelin sheaths, separation of myelin lamellae and degenerative changes in the oligodendrocytes population.

Conclusion: Cognitive decline related to aging may occur in part due to the disturbed myelination of axons in CNS white matter.     

Using photographs to explore self-understanding in adolescent boys with an autism spectrum condition

Background: Research evidence suggests that self-understanding is likely to be limited in individuals with autism.

Method: Photo-elicitation interview was used to explore self-understanding in five adolescent boys diagnosed with an autism spectrum condition.

Results: An interpretative phenomenological analysis yielded three superordinate themes: self in action, self extended in time and self in relation to others. These themes captured how participants understood themselves in terms of their actions and abilities, in the context of their past and future and in relation to others.

Implications: The findings suggested that self-understanding is informed by relationships with parents, self-other comparisons and by reflecting on past and future selves, as well as on activities engaged in. Photo-elicitation was effective in engaging participants with the research process.     

Impaired lexical selection and fluency in post-stroke aphasia

Background: Deficits in fluent language production are a hallmark of aphasia and may arise from impairments at different levels in the language system. It has been proposed that difficulty resolving lexical competition contributes to fluency deficits.

Aims: The present study tested this hypothesis in a novel way: by examining whether narrative speech production fluency is associated with difficulty resolving lexical competition in spoken word recognition as measured by sensitivity to phonological neighborhood density.

Methods & Procedures: Nineteen participants with aphasia and 15 neurologically intact older adults identified spoken words that varied in phonological neighborhood density and were presented in moderate noise.

Outcomes & Results: Neurologically intact participants exhibited the standard inhibitory effect of phonological neighborhood density on response times: slower recognition of spoken words from denser neighborhoods. Among participants with aphasia, the inhibitory effect of phonological neighborhood density (less accurate recognition of spoken words from denser neighborhoods) was smaller for participants with greater fluency. The neighborhood effect was larger for participants with greater receptive vocabulary knowledge, indicating that the fluency effect was not a result of general lexical deficits.

Conclusions: These results are consistent with the hypothesis that impaired lexical selection is a contributing factor in fluency deficits in poststroke aphasia.     

Perspectives of carers of people with intellectual disability accessing general practice: “I’d travel to the ends of the earth for the right person”⁣

Background: Informal carers often play an integral role in the lives of people with intellectual disability (ID) residing in the community. In this study, we explored the extent to which carers of people with ID believe that the health care needs of the person they care for are being accommodated by general practice.

Method: Semi-structured interviews were conducted with 25 informal carers to people with ID living in Australia.

Results: Carers of people with ID report that they experience considerable barriers to accessing general practice care on behalf of the people they care for.

Conclusions: Given the ever-increasing number of people with ID now living in the community and their vulnerability to health problems, it is imperative that future research focuses on the development of strategies to overcome the barriers identified in this study.     

Screening Adherence for Depression Post Stroke: Evaluation of Outpatients,a London Experience (SAD PEOPLE)

Background: Post stroke depression (PSD) is common, and the transition home following discharge may be especially challenging for stroke survivors.

Objectives: This study aimed to determine how well specific Canadian Best Practice Recommendations for PSD screening were adopted within a stroke rehabilitation outpatient clinic before and after the utilization of a standardized clinical form.

Methods: Practices were evaluated through retrospective chart review before and after the implementation of the standardized form which cued physicians to administer the Patient Health Questionnaire 9 (PHQ-9) at the first outpatient visit. Participants included those aged ≥18 years with a primary diagnosis of stroke.

Results: One hundred thirty-five subjects’ charts were reviewed. Form implementation was associated with increased rates of PSD screening (93.8% versus 0%) and charting regarding mood (55.4% versus 15.7%).

Conclusion: This study highlights the frequency of depressive symptoms in an outpatient cohort and demonstrates how screening rates can be improved by using a standardized form. Routine PHQ-9 completion at the first outpatient visit was associated with more physician–patient discussion and documentation regarding mood.
