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.     

Perspective of patients and caregivers about stroke rehabilitation: the Quebec experience

Background: The unique perspectives of patients and caregivers on their experiences as users of rehabilitation services help identify areas for improvement for the continuum from acute care to community integration.

Objective: This study reports perceptions of persons with stroke and their caregivers in an existing continuum of stroke care, social services, and rehabilitation in the Province of Quebec.

Methods: A total of 10 focus groups were held, 5 with persons with stroke (n = 37, mean age 59.6 years (SD = 11.6); 21 men) and 5 others with caregivers (n = 31; mean age 58.8 years (SD = 15.1); 8 men). Discussions were transcribed and were the object of thematic content analysis using Nvivo.

Results: Participants expressed their general satisfaction toward the care received in inpatient, hospital, and rehabilitation settings. The information received about acute care, however, was deemed insufficient and fragmented, and access of rehabilitation services was often perceived to be difficult. In the community integration phase of the continuum, most participants stated that they had experienced poor accessibility to services of any kind.

Conclusions: Persons with stroke and their relatives’ perspectives about the services that they obtained throughout the rehabilitation continuum vary importantly according to the services examined. Adopting a continuum perspective is helpful to target priorities for improvement.     

Psychosocial functioning in adolescents: results according to Amiel-Tison neurological assessment in a group of preterm infants

Objective: This prospective study investigated the relationship between Amiel-Tison neurological assessment (ATNA) in preterm children and their psychosocial functioning in adolescence.

Methods: From the initial group of 45 children regularly assessed by the ATNA from term until the age of 2 years, 27 participated in the follow-up at 13 years.

Results: Of the three groups categorized by neurological signs as normal, intermediate or abnormal, parents of adolescents with normal ATNA reported the lowest number of executive function problems (p = 0.019) and behavioral symptoms (p = 0.011), while the adolescents themselves reported the lowest number of behavioral symptoms (p = 0.005) and the highest quality of life (p = 0.012). The number of problems reported increased with the number of abnormal neurological signs.

Conclusion: Standardized neurological assessment may be a helpful clinical tool for the identification of children at risk for later psychosocial problems who could benefit from prevention and early intervention programs.     

Effects of the hybrid of neuromuscular electrical stimulation and noxious thermal stimulation on upper extremity motor recovery in patients with stroke: a randomized controlled trial

Background: Neuromuscular electrical stimulation (NMES) and noxious thermal stimulation (NTS) have been developed and incorporated in stroke rehabilitation.

Objective: This study aimed to compare the effects of NMES, NTS, and the hybrid of NMES and NTS (“Hybrid”) on motor recovery of upper extremity (UE) for patients with stroke.

Methods: We conducted a prospective, single-blind randomized controlled trial with concealed allocation. Forty-three patients with chronic stroke (onset >6 months) were randomly assigned to three groups (NMES, NTS, and “Hybrid”). In addition to conventional rehabilitation, participants received 30 min of NMES or 30 min of NTS or 15 min of NTS followed by 15 min of NMES. The treatment period was 8 weeks, 3 days/week, 30 min/time. The UE subscale of Fugl-Meyer assessment (UE-FMA, the primary outcome), Motricity index, modified Ashworth scale, and Barthel index were administered by a blinded assessor at baseline, posttreatment, and one-month follow-up.

Results: Most of the participants had mild-to-moderate disability in activity of daily living. No significant differences in the outcome measures at posttreatment and one-month follow-up were found among the NMES group (n = 13), NTS group (n = 13), and the hybrid of NMES and NTS group (n = 17). However, significant score changes in UE-FMA (p < 0.025) from baseline to posttreatment and one-month follow-up were found for the “Hybrid” group.

Conclusions: This study reveals that the hybrid of NMES and NTS therapy appears to be beneficial to UE recovery after stroke but is not superior to NMES or NTS alone.     

Social circus program (Cirque du Soleil) promoting social participation of young people living with physical disabilities in transition to adulthood: a qualitative pilot study

Purpose: To explore the perceived impact of a social circus program on the participation level of young adults’ living with physical disabilities from their own and their parents’ perspective.

Method: Exploratory phenomenological qualitative design. A social circus program was offered for nine months. Perceived participation level was documented through pre and post semi-structured interviews. A pretested interview guide was used. Interviews were transcribed and coded by two independent researchers.

Results: The average age of the participants (n = 9) was 20.0 ± 1.4 years with 2/9 being female. Participation was perceived as being improved after the intervention from both perspectives (participants and parents) mainly for communication, mobility, relationships, community life and responsibilities. The intervention was perceived as strengthening self-perception and self-efficacy, which in turn enhanced participation level and decreased parents’ bounding.

Conclusion: The results show promises for social circus as a new approach in adult physical rehabilitation for this population in transition.     

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.     

Psychometric properties of the Dutch SAQOL-39NL in a generic stroke population

Background: The psychometric properties of the Dutch version of the Stroke and Aphasia Quality Of Life-scale (SAQOL-39NL) have previously been assessed for people with aphasia after stroke, but not yet for stroke survivors without aphasia.

Objective: The objective is to evaluate the psychometric properties of the SAQOL-39NL in a stroke sample with and without aphasia.

Methods: The SAQOL-39NL was administered to survivors of stroke (N = 141) who received rehabilitation in specialized rehabilitation facilities, 3 and 6 months after the start of rehabilitation. Acceptability was explored by assessing floor and ceiling effects and missing items. For internal consistency, Cronbach’s alpha and item-total correlations were computed. For internal validity, intercorrelations between domains, and between domains and total score, were assessed. Convergent validity was evaluated by correlation with EuroQoL-5D scores. Responsiveness to change was investigated using d′ and SRM-scores.

Results: Mean age was 60.4 years (SD = 11.1), 62.4% were male. Mean total SAQOL-39NLg score was 3.94 (SD = 0.68, scale 1–5). No floor or ceiling effects and 2.4% missing data were found. Internal consistency was excellent (Cronbach’s alpha = 0.96). Intercorrelations between domains and total scale were moderate to excellent (r = 0.57–0.88). Intercorrelations between domains were low to moderate (r = 0.22–0.63). The correlation with the EQ-5D was moderate (r = 0.57). Only small changes in SAQOL-39NLg scores were found between 3 and 6 months.

Conclusions: These data provide further evidence for the acceptability, internal consistency, and initial promising data on validity of the SAQOL-39NLg. Further research on structural validity and responsiveness to change is needed.     

Four-week training involving ankle mobilization with movement versus static muscle stretching in patients with chronic stroke: a randomized controlled trial

Background: Patients with stroke generally have diminished balance and gait. Mobilization with movement (MWM) can be used with manual force applied by a therapist to enhance talus gliding movement. Furthermore, the weight-bearing position during the lunge may enhance the stretch force.

Objectives: This study aimed to compare the effects of a 4-week program of MWM training with those of static muscle stretching (SMS). Ankle dorsiflexion passive range of motion (DF-PROM), static balance ability (SBA), the Berg balance scale (BBS), and gait parameters (gait speed and cadence) were measured in patients with chronic stroke.

Methods: Twenty patients with chronic stroke participated in this study. Participants were randomized to either the MWM (n = 10) or the SMS (n = 10) group. Patients in both groups underwent standard rehabilitation therapy for 30 min per session. In addition, MWM and SMS techniques were performed three times per week for 4 weeks. Ankle DF-PROM, SBA, BBS score, and gait parameters were measured after 4 weeks of training.

Results: After 4 weeks of training, the MWM group showed significant improvement in all outcome measures compared with baseline (p < 0.05). Furthermore, SBA, BBS, and cadence showed greater improvement in the MWM group compared to the SMS group (p < 0.05).

Conclusions: This study demonstrated that MWM training, combined with standard rehabilitation, improved ankle DF-PROM, SBA, BBS scores, and gait speed and cadence. Thus, MWM may be an effective treatment for patients with chronic stroke.     

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)     

Effects of Botulinum Toxin A Injection on Ambulation Capacity in Patients with Cerebral Palsy

Purpose: The purpose of the study is to assess the change in their ambulatory capacity and spasticity in children with cerebral palsy (CP) who received botulinum toxin A (BoNT-A) injection and underwent rehabilitation therapy.

Methods: Thirty patients with CP, 3–13 years who had varied functional levels and lower extremity spasticity, were randomized in two groups. In Group 1(n = 15), BoNT-A was administered to the affected extremity and underwent rehabilitation. In Group 2 (n = 15), the patients underwent only rehabilitation protocol. The Visual Analogue Scale (VAS), Tardieu Scale (TS), Gross Motor Function Classification System (GMFCS), Selective Motor Control, and Goal Attainment Scale were evaluated 4 and 12 weeks after baseline.

Results: The mean scores of the TS (p < 0.001) GMFCS, GAS, and VAS (p < 0.05) significantly improved in Group 1.

Conclusion: We think that implementation of rehabilitation protocols with BoNT-A injection is superior to alone rehabilitation therapy and increasing ambulatory capacity in patients with CP.     

Differences in sleep patterns,sleepiness, and physical activity levels between young adults with autism spectrum disorder and typically developing controls

Objective: To investigate the differences in sleep, sleepiness, and physical activity (PA) between young adults with autism spectrum disorder (ASD) and typically developing controls (TDC).

Method: Actigraphic data and questionnaires on sleep, sleepiness, and PA were compared between fifteen adults with ASD (ADOS range 7–19; ages 22.8 ± 4.5 years) and TDC.

Results: In comparison to the TDC group, the ASD group slept longer on average per night but took longer to fall asleep. In relationship to PA levels, the objective PA levels were lower in the ASD group than the TDC group. Fewer wake minutes during the sleep period in the ASD sample were associated with more PA the following day.

Conclusion: The findings support previous research that demonstrates differences in sleep parameters and PA between ASD and TDC. Interventions aimed at increasing PA in an ASD population may be beneficial for improved sleep.     

Mirror therapy and treadmill training for patients with chronic stroke: a pilot randomized controlled trial

Background: Previous lower-limb mirror therapy research has focused on non-weight bearing interventions.

Objectives: The primary aim of this study was to investigate the effect and feasibility of a combination of mirror therapy and treadmill training on post-stroke lower-limb recovery compared to a placebo intervention.

Methods: All patients (N = 30) walked on a treadmill for 30 min per day, 3 days per week, for 4 weeks. The mirror therapy and treadmill training group (n = 15) walked on the treadmill while viewing a reflection of their non-paretic limb in a mirror positioned in their mid-sagittal plane. The placebo group (n = 15) received no mirror visual feedback due to an altered mirror position. Primary outcome measures: Ten Metre Walk Test (10MWT) and Six Minute Walk Test (6MWT). Secondary outcome measures: Modified Ashworth Scale (MAS) and Fugl-Meyer Assessment-Lower Extremity (FMA-LE). Feasibility was appraised by examining participant compliance and any adverse events.

Results: No significant between group differences were demonstrated for the 10MWT, 6MWT or FMA-LE at post-training or 3-month follow-up assessment. A significant between group difference on the MAS was demonstrated in the reduction of ankle dorsiflexion muscle tone (p = 0.006) and ankle plantarflexion muscle tone (p = 0.01) in the mirror therapy group compared to the placebo group at post-training assessment but not at 3-month follow-up.

Conclusion: Our study reveals that in our group of patients with chronic stroke, mirror therapy combined with treadmill training facilitated significant reductions in ankle muscle tone (p < 0.05) compared to a placebo intervention.     

Intellectual,educational, and situation-based social outcome in adult survivors of childhood medulloblastoma

Purpose: To investigate intellectual and situation-based social outcome and educational achievement in adult survivors of childhood medulloblastoma and analyse factors influencing outcome

Methods: We collected demographic, medical and cognitive data, and social and educational outcome at a mean time since the end of treatments of 14.9 years in 58 adults, aged 19–35 years, consecutively treated in a single cancer center between 1989 and 2005.

Results: Ten survivors had severe intellectual disability, 12 were still studying, 23 had a regular employment and 13 were unemployed. Full Scale Intellectual Quotient, assessed 6.6 years after the end of treatments, ranged from 46 to 131. It was strongly associated with educational achievement and significantly lower in patients who experienced postoperative cerebellar mutism, and when parental education level was low.

Conclusion: These factors should be systematically considered at diagnosis in order to offer adequate and timely assessments and interventions.     

Cross-language generalisation in bilingual aphasia: what are we missing when we do not analyse discourse?

Background: Cross-language generalisation has been reported in about half of all published cases of bilingual aphasia treatment. However, many of those studies report data from only single-word naming tasks. In unbalanced bilinguals with aphasia, treating the post-morbidly less proficient language may result in apparent improvement to only the treated language.

Aims: To investigate whether when tools are used to measure language abilities beyond the single-word and sentence levels, such as analysing discourse production, improvement in the post-morbidly more proficient language may be observed.

Methods & Procedures: A Hebrew-English bilingual person with mild-moderate non-fluent agrammatic aphasia was recruited. He received 36 h of Verb Network Strengthening Treatment (VNeST) in English only, with pre- and post- treatment assessment of his language abilities in both English and Hebrew.

Outcome & Results: Significant improvement was observed in the treated language (English) for noun and verb retrieval in object and action picture naming and within sentence production, but not for the untreated language (Hebrew). In discourse, greater and more widespread improvement was observed in the untreated language (Hebrew) than in the treated language (English).

Conclusions: We advocate for more wide-ranging measurement tools in the field to reduce the risk of missing valuable information regarding generalisation. Only with a more representative understanding of the effects of language treatment in bilinguals with aphasia can we better understand the mechanisms behind cross-language generalisation.     

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.     

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.     

General movements and motor outcomes in two infants exposed to Zika virus: brief report

Objective: We described the general movements (GMs) in the fidgety period and the motor performance of two infants who were exposed to Zika virus (ZIKV) during distinct trimesters of gestation.

Methods: Infants were assessed at 4 and 12 months of age. Prechtl's GM assessment and the Alberta Infant Motor Scale were used.

Results: In Case 1, the mother presented confirmed ZIKV infection in the 10th week of gestation and the infant was born full-term with brain abnormalities and microcephaly. Fidgety movements were absent at 16 weeks after term and motor development was severely impaired at 12 months of age. In Case 2, the mother presented confirmed ZIKV infection in the 34th week of gestation and the infant was born full-term with no signs of brain changes or microcephaly. Fidgety movements at 13 weeks were normal in presentation and motor outcome was typical at 12 months.

Conclusion: GM assessment can be useful for ZIKV-exposed infants. These findings represent the first information on GMs and long-term motor outcomes in ZIKV-exposed infants.     

Effects of phonomotor treatment on discourse production

Background: Aphasia is an acquired language disorder that makes it difficult for people to produce and comprehend language, with all people with aphasia (PWA) demonstrating difficulty accessing and selecting words (anomia). While aphasia treatments typically focus on a single aspect of language, such as word retrieval, the ultimate goal of aphasia therapy is to improve communication, which is best seen at the level of discourse.

Aims: This retrospective study investigated the effects of one effective anomia therapy, Phonomotor Treatment (PMT), on discourse production.

Methods & Procedures: Twenty-six PWA participated in 60 h of PMT, which focuses on building a person’s ability to recognize, produce, and manipulate phonemes in progressively longer nonword and real-word contexts. Language samples were collected prior to, immediately after, and 3 months after the treatment program. Percent Correct Information Units (CIUs) and CIUs per minute were calculated.

Outcomes & Results: Overall, PWA showed significantly improved CIUs per minute, relative to baseline, immediately after treatment and 3 months later, as well as significantly improved percent CIUs, relative to baseline, 3 months following treatment.

Conclusions: PMT, which focuses on phonological processing, can lead to widespread improvement throughout the language system, including to the functionally critical level of discourse production.     

Selection for sentence generation in the context of severe anomia: A case series of left temporal patients

Introduction: Anomia is an impairment of naming: the retrieval of specific lexical items from the mental lexicon. Theoretically, whether anomia reflects a failure of selection at the preverbal “idea” level or at the subsequent linguistic formulation stage remains a topic of debate. We investigated the preverbal mechanism of idea selection for sentence generation, which requires the selection of a proposition from among competing alternatives during message formulation, in patients with severe anomia.

Method: Patients with lesions to the left temporal lobe (N = 12), presenting with clinically defined anomia, and matched healthy controls (N = 24) completed sentence-level tasks that required the oral generation of a sentence or single word when presented with a word, a word pair, or a sentence. Selection demands were manipulated so that the stimuli activated many competing response options (low constraint) or one dominant or few response options (high constraint).

Results: There was no effect of stimuli constraint in the patient group that differed from that in the healthy control group on any of the generation tasks, suggesting that idea-level selection is intact in the patient group.

Conclusions: These findings have implications for theoretical models of spoken language production and for clinical treatments of anomia.
