Rasch analysis of the upper-limb subscale of the stroke rehabilitation assessment of movement (STREAM) tool in an acute stroke cohort Rasch analysis of the upper-limb subscale of the STREAM tool in an acute stroke population

Background: Stroke is a leading cause of disability worldwide. The most common impairment resulting from stroke is upper-limb weakness.

Objectives: To determine the usefulness and psychometric validity of the upper-limb subscale of the STREAM in an acute stroke population.

Methods: Rasch Analysis, including unidimensionality assumption testing, determining model fit, and analysis of: reliability, residual correlations, and differential item functioning.

Results: 125 individuals were assessed using the upper-limb subscale of the Stroke Rehabilitation Assessment of Movement (STREAM) tool. Rasch analysis suggests the STREAM is a unidimensional measure. However, when scored using the originally proposed method (0–2), or using the response pattern (0–5) neither variant fit the Rasch model (p < 0.05). Although, the reliability was good (Person-Separation Index – 0.847 and 0.903, respectively). Correcting for the disordered thresholds, and thereby producing the new scoring pattern, led to substantial improvement in the overall fit (chi-square probability of fit – 22%), however, the reliability was slightly reduced (PSI – 0.806).

Conclusions: The study proposes a new scoring method for the upper-limb subscale of the STREAM outcome measure in the acute stroke population.     

Hand function and type of grasp used by chronic stroke individuals in actual environment

Background: Knowledge of paretic upper limb (UL) use in the actual environment is crucial for defining treatment strategies that are likely to enhance performance.

Objective: To quantify the hand function and type of grasp performed in the actual environment following stroke and determine if any differences in hand use are dependent on the degree of motor impairment.

Method: This cross-sectional study enrolled 41 participants with chronic hemiparesis classified as having either mild (11), moderate (20), or severe (10) UL impairment. A behavioral map was used while observing hand use over the 4-h experimental period, during which we checked: activity- unimanual, bimanual or non-task-related; hand function- stabilization, manipulation, reach-to-grasp, gesture, support or push; and type of grasp- digital or whole-hand.

Results: Participants with severe impairment did not use the paretic UL spontaneously; analyzing the moderate and mild subgroup together, the predominant UL hand functions were stabilization and manipulation, the paretic UL performs the stabilization function using the whole-hand more frequently (71.2%) than digital (28.8%) grasp. In the subgroup analysis, the paretic and non-paretic UL in the moderate and the paretic UL in the mild subgroup perform the whole-hand stabilization more frequently than digital. Digital grasp is more accomplished by the non-paretic UL in reach-to-grasp hand function, particularly in the mild subgroup.

Conclusion: The paretic UL is predominantly employed for stabilization function using a whole-hand grasp. The type of grasp in the actual environment is affected by motor impairment, and greater motor impairment leads to the performance of less complex tasks.     

Choosing among second-generation antidepressant treatments for depressed patients with cardiac diseases

Objectives: The present paper aimed to assist physicians in the accurate choice among second-generation agents (SGAs) for patients with cardiovascular disease (CVD).

Methods: We reviewed the published pharmacokinetic (PK) and pharmacodynamic (PD) clinical data that report potential -or absence of- drug interactions between second-generation agents (SGAs) and CVD drugs most commonly used in cardiology, including antiplatelet drugs and anticoagulants, statins, beta-blockers, angiotensin-converting enzyme inhibitors, calcium channel blockers, diuretics and the antiarrhythmic drugs amiodarone and digoxin.

We also reviewed the cardiovascular safety profile that has been published for each class of SGAs and side effects reported by patients with CVD.

Results: Most relevant PK/PD data about SGAs and CVD drugs are based on small studies or detailed case reports. In many cases, the drug interactions are at most assessed in healthy volunteers so that the clinical relevance of findings needs further investigation in patients with CVD. Case reports of serious, sometimes fatal reactions due to concomitant administration of certain drugs require careful consideration.

The major cardiac side effects of SGAs include HR increase, postural hypotension and slight prolongation of the intraventricular conduction time and QT interval. On normal dosage of antidepressants, both advanced heart block and ventricular arrhythmias could occur in patients with severe heart disease, together with clinically important loss of myocardial contractile force.

Conclusions: Data reported in the present review should help physicians about their decision-making processes that govern SGAs use in CVD patients.     

Sensitivity to change and responsiveness of the Segmental Assessment of Trunk Control (SATCo) in children with spinal cord injury

Purpose: The purpose of this study was to assess the sensitivity and responsiveness of the Segmental Assessment of Trunk Control (SATCo) for evaluating trunk control in children with spinal cord injury (SCI) receiving activity-based locomotor training (AB-LT).

Methods: Prospective study of nine outcomes for consecutively enrolled children in outpatient AB-LT. To evaluate sensitivity to change, linear-mixed models were constructed and adjusted for covariates: age at and time since SCI. To evaluate responsiveness, standardized response means and 95% confidence intervals were estimated per outcome.

Results: SATCo scores increased significantly (p < 0.05) regardless of chronicity, initial score, and injury level. The SATCo was the most responsive measure and the only outcome demonstrating a large effect size after 3 months of therapy.

Conclusions: Children with SCI receiving AB-LT improved trunk control regardless of chronicity, initial impairment, or prior experience. SATCo sensitivity and responsiveness support its usefulness in measuring trunk control in children with SCI.     

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.     

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.     

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.     

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.     

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.     

Systematic review of orthoses for stroke-induced upper extremity deficits

Background: Orthoses for individuals with stroke is considered an integral part of the neurorehabilitation process. However, there are no universal guidelines to determine the initiation period, duration, or type of orthosis for stroke patients.

Objectives: For this study, we systematically reviewed the evidence surrounding the use of orthoses for stroke-related upper extremity deficits.

Methods: Medical librarians searched MEDLINE, EMBASE, CINAHL, Cochrane Database of Systematic Reviews, Cochrane Controlled Trials Register, Health Technology Assessment Database, Physiotherapy Evidence Database, and OTSeeker using subject headings and keywords related to upper extremities, orthoses, and stroke. The resulting articles were evaluated for inclusion by the systematic review team. Articles that met the inclusion criteria were appraised for content and quality using the “Evaluation Guidelines for Rating the Quality of an Intervention Study” (EQIS).

Results: 14 studies were included, with the mean score of 31.29 (out of 48) for the EQIS using an ordinal scale with a range of 23–43.6 studies produced significant outcomes with effect sizes ranging from d = .52 (wrist flexion PROM) to d = 9.02 (patient satisfaction with orthosis).

Conclusion: Future studies should aim to utilize homogenous outcome measures while exploring variability in dosage and level of upper extremity impairment upon initiation. Additionally, universal guidelines for initiation period, duration, and type of orthosis for patients post-stroke need to be established.     

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.     

Characteristics of the shoulder in patients following acute stroke: a case series

Background: Stroke can result in pain and loss of motor control in the hemiplegic shoulder, and while prevention of secondary changes is likely to be the most effective management, there is limited evidence directing clinicians towards the most at-risk patients.

Objectives: The aim of this case series was to investigate the presentation of shoulder pain, motor impairment, shoulder passive range of motion (PROM) and alignment of the hemiplegic shoulder following acute stroke.

Methods: This study reported data that was collected as part of a pilot randomized controlled trial investigating kinesiology taping of the hemiplegic shoulder. Participants with a diagnosis of acute stroke and severe upper limb motor impairment were included. From 24-h post stroke and continuing every three days until discharge, measurements of shoulder pain (visual analogue scale, Ritchie Articular Index), motor impairment (Chedoke McMaster Stroke Assessment), PROM and alignment (both clinical measures) were collected. Clinical trial registry number – ACTRN12615000502538.

Results: Of 156 patients screened over six months, 10 of 15 eligible participants were recruited. On initial assessment, three participants reported pain and all had severe upper limb motor impairment. All participants initially demonstrated close to full shoulder PROM. Six participants had shoulder subluxation and five demonstrated scapula malalignment.

Conclusions: Given the severity of upper limb motor impairment, pain and reduced PROM were seen in a small number of participants. The clinical course of shoulder pain and PROM following stroke remains unclear. Large observational studies tracking shoulder characteristics from acute through to rehabilitation settings are needed.     

Characterising omission errors in everyday task completion and cognitive correlates in individuals with mild cognitive impairment and dementia

Objective: Functional ability declines with age and cognitive impairment. This study investigated errors of omission made by community-dwelling older adults completing everyday tasks in a naturalistic setting.

Method: Sixty-five cognitively healthy older adults (HOA), 19 individuals with single domain mild cognitive impairment (sdMCI), 33 individuals with multi-domain MCI (mdMCI), and 13 individuals with dementia completed measures of memory, processing speed, working memory, and executive functioning, as well as eight different activities of daily living in a naturalistic environment. Task steps were divided into preparatory, action-oriented, and concluding steps.

Results: For action-oriented steps, the number of omission errors increased with level of cognitive impairment beyond sdMCI (i.e., HOA?=?sdMCI?<?mdMCI?<?dementia). In contrast, for preparatory and concluding steps, the dementia group committed more omission errors than the HOA, sdMCI, and mdMCI groups, which did not differ.

Conclusions: The results suggest that the more complex and integrative action-oriented steps may be the first type of everyday task step to be affected in the process of cognitive decline, with preparatory and concluding steps being preserved longer and only showing decline in later stages of impairment (i.e., dementia). Individuals with sdMCI may use other intact abilities to compensate for task omission errors.     

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)     

Pain intensity,depressive symptoms,and functional limitations among older adults with serious mental illness

Objective: To examine pain-related activity interference as a mediator for the relationship between pain intensity and depressive symptoms among older adults with serious mental illness (SMI).

Method: Ordinary least-squares regressions were used to investigate the mediation analysis among older adults with SMI (n = 183) from community mental health centers. Analyses used secondary data from the HOPES intervention study.

Results: Higher pain intensity was associated with greater pain-related activity interference. Higher pain intensity and pain-related activity interference were also associated with elevated depressive symptoms. Finally, greater pain-related activity interference significantly mediated the association between higher pain intensity and elevated depressive symptoms.

Conclusions: These findings demonstrate that pain and depressive symptoms may be linked to functional limitations. Clinicians and researchers in the mental health field should better address pain-related activity interference among older adults with SMI, especially among those with higher pain intensity and elevated depressive symptoms.     

Oxyhemoglobin changes in the prefrontal cortex in response to cognitive tasks: a systematic review

Purpose of the study: the aim of this study was to synthesize PFC fNIRS outcomes on the effects of cognitive tasks compared to resting/baseline tasks in healthy adults from studies utilizing a pre/post design.

Material and methods: original research studies were searched from seven databases (MEDLINE, EMBASE, CENTRAL, CINAHL, SCOPUS, PEDro and PubMed). Subsequently, two independent reviewers screened the titles and abstracts followed by full-text reviews to assess the studies' eligibility.

Results: eleven studies met the inclusion criteria and had data abstracted and quality assessed. Methodology varied considerably and yet cognitive tasks resulted in the ΔO₂Hb increasing in 8 of the 11 and ΔHHb decreasing in 8 of 8 studies that reported this outcome. The cognitive tasks from 10 of the 11 studies were classified as “Working Memory” and “Verbal Fluency Tasks”.

Conclusions: although, the data comparison was challenging provided the heterogeneity in methodology, the results across studies were similar.     

Spiritual care for people with intellectual and developmental disability: An exploratory study

Background: A faith-based (pseudonym, Adam’s House – AH) and a non-faith-based care service (pseudonym, Greenleaves – GL) were explored to find out if and how spiritual support was provided for people with intellectual and developmental disabilities (IDDs).

Method: Six months were spent volunteering within each service and a mixed-methods approach was utilised including applied and ethnographic methods to explore and describe if and how spirituality was embedded within the two services.

Results: Themes found included community of value; homely functional care; and barriers to spiritual care. GL staff tended to provide what we termed “religious spiritual care” while AH staff administered both “religious” and “non-religious” spiritual-based support. This difference may be related to the type of training found only at AH which included spiritual dimensions.

Conclusion: Services could benefit from acknowledging the importance and significance of spiritual care training and education for effective and varied spiritual care for people with IDD who desire such support.     

AAC technologies with visual scene displays and “just in time” programming and symbolic communication turns expressed by students with severe disability

Background: The current study investigated the impact of an intervention that included aided augmentative and alternative communication (AAC) technologies on the frequency of symbolic communication turns of school-age children, adolescents, and young adults with severe disability.

Method: Nine students ages 8–20 were engaged in interactive activities using an aided AAC system with visual scene displays (VSDs; concepts embedded within a photograph of a naturally occurring event), and “just-in-time” (JIT) programming (the capability to add new contexts “on the fly”). Effectiveness was evaluated using a single subject multiple probe across participants design.

Results: All participants demonstrated increases in symbolic communication turns upon introduction of the AAC technologies with VSDs using JIT technology.

Conclusions: AAC with VSDs and JIT programming may be effective in increasing symbolic communication for students with severe developmental disability. The fast and easy creation of VSDs and hotspots to provide communication may be a valuable tool for interventionists.
