Impact of Upper Limb Function and Employment Status on Return to Work of Blue-Collar Workers after Stroke

Determinants of Return to Work After a Stroke: A Systematic Review and Meta-analysis

OBJECTIVE

To identify prognostic factors for return to work (RTW) after stroke.

DATA SOURCES

PubMed, MEDLINE, Cochrane, and Embase were systematically searched.

STUDY SELECTION

Studies had to include people of working age (<65 years old) at the time of stroke (ischemic, hemorrhagic, or subarachnoid hemorrhage). The evaluation of RTW and rate of RTW had to be mentioned. Study selection was done by 2 independent authors. In total, 1241 articles were screened, 39 met all inclusion criteria.

DATA EXTRACTION

Characteristics of included studies were recorded independently by 2 authors. Differences were resolved through discussion or with a third author. Quality was assessed using the Scottish Intercollegiate Guidelines Network quality assessment tool.

DATA SYNTHESIS

Among the 39 studies, prognostic factors for RTW were hemorrhagic stroke (odds ratio 0.53 [95% confidence interval 0.45-0.60], n=18 studies), sex (men) (1.26 [1.14-1.40], n=31), aphasia (0.37 [0.20-0.69], n=7), occupation (white collar worker) (1.84 [1.64-2.06], n=17), independence in activities of daily living (3.99 [1.73-9.23], n=7), and stroke severity (NIHSS) (1.23 [1.08-1.39], n=6).

CONCLUSIONS

This meta-analysis highlighted positive and negative prognostic factors associated with RTW after stroke. Two categories were distinguished: modifiable and non-modifiable prognostic factors. This study provides information to help understand the issues, set appropriate objectives and implement appropriate strategies to guide people to RTW after stroke. Randomized controlled studies are needed to better evaluate work-place intervention programs as well as the effects of intravenous thrombolysis, and cognitive and neuropsychological rehabilitation on return-to-work rates after stroke.

Return to work for adults following stroke: a scoping review of interventions, factors, barriers, and facilitators

OBJECTIVE

This scoping review aimed to map the literature on interventions, factors, barriers, and facilitators for return to work for adults post-stroke with or without communication disorders.

INTRODUCTION

Difficulties in returning to work can significantly impact individuals following a stroke (eg, their sense of purpose and self-esteem), not only financially, but also as they adjust to the change in their situation. Such difficulties may arise from communication disorders as well as physical impairments. Previous reviews on return to work post-stroke have focused on specific aspects, such as interventions, or barriers and facilitators, but have not provided a comprehensive map of the field. Further, no systematic or scoping reviews to date have focused on literature addressing return to work for people with communication disorders post-stroke.

INCLUSION CRITERIA

This review considered literature that reported on interventions, barriers, and facilitators for return to work for adults (aged 16 years or older) following an ischemic or hemorrhagic stroke. Records focusing on transient ischemic attacks or acquired brain injury were excluded, as were those in which a comorbidity or disability (eg, learning disability, dementia, respiratory disorder) had a significant impact on the individual's ability to work.

METHODS

This review followed the JBI scoping review methodology. Primary research of any type, systematic and non-systematic reviews, and gray literature from developed countries written in English from 2010 to the present day were identified from 7 databases, 2 gray literature repositories, JBI Evidence Synthesis , and an internet search. Records were screened for relevance to the review topic by 2 independent reviewers, and data relevant to the review questions were extracted. Findings were presented as narrative supported by tables.

RESULTS

Of the 106 sources included, 61 addressed demographic-based, socioeconomic-based, impairment-based, or recovery-based factors related to return to work. One of these 61 sources, a narrative review, focused on communication disorders. Thirty-eight sources explored barriers and facilitators for return to work from different stakeholders' perspectives; 3 of these 38 sources, including 2 qualitative studies and 1 narrative review, focused on post-stroke communication disorders. Eleven sources focused on interventions, including 7 studies (reported across 9 sources) that developed or tested return-to-work interventions. Of these primary studies, 1 randomized controlled trial and 1 retrospective cohort study were identified. The remaining intervention studies were case studies or case series. None of these intervention studies addressed communication disorders.

CONCLUSIONS

While there has been extensive research on factors, barriers, and facilitators for return to work post-stroke, there is a lack of research on interventions supporting return to work. There is also a significant gap in the evidence base on returning to work with a post-stroke communication disorder, highlighting the need for further research in this important area.

[Work Participation after Multimodal Rehabilitation due to Neurological Diseases - Representative Analyses Using Routine Data of the German Pension Insurance]

PURPOSE

There is little representative evidence for the German rehabilitation system on occupational reintegration after medical rehabilitation. For persons who have undergone rehabilitation on behalf of the German Pension Insurance (GPI) due to a neurological disease, it is therefore important to determine (a) what socio-medical risks exist prior to rehabilitation, (b) how well persons were able to participate in working life after rehabilitation, and (c) what conditions determine the work participation.

METHODS

The study is conducted on the basis of the GPI's database of rehabilitation statistics. Included were all persons, who completed medical rehabilitation in 2016 due to a neurological disease. The analyses were carried out for the entire group and also in a differentiated manner for the 2 main diseases, cerebrovascular diseases (CD) and multiple sclerosis (MS). Work participation was operationalized both via a monthly status variable until 24 months after rehabilitation and as a rate of all persons who were employed at the 12 and 24 months follow up and in the 3 months before, respectively. To analyse the factors influencing stable work participation, multiple logistic regression models with stepwise inclusion were calculated separately for the rates after 12 and 24 months.

RESULTS

A total of 42,230 data sets were included in the analysis (CD: n=18,368, 44%; MS: n=6,343, 15%). Patients with neurological diseases were 50 years old on average, 43% were female. We found that approximately15% of patients reported no absenteeism, whereas 17% stated an absence leave of six months or more in the year prior to rehabilitation. Mental and cardiovascular comorbidity was documented in 31 and 44% of the cases respectively. Nearly 48% of patients with CD returned to work two years after rehabilitation. For MS patients, the percentage was slightly higher at 54%. The amount of sick leave of the rehabilitated individual, their gross/net income prior to rehabilitation as well their work capacity prior to admission were the three strongest influencing factors on their return to the labour market.

CONCLUSION

About half of all persons with neurological diseases return to sustainable work after medical rehabilitation in Germany. The amount of sick leave and the income before rehabilitation are determining factors as to whether the person will return to work. The analysis provides representative data on occupational reintegration after medical rehabilitation due to a neurological disease for the first time.

Pre-stroke socioeconomic status predicts upper limb motor recovery after inpatient neurorehabilitation

BACKGROUND

Lower socioeconomic status (SES) is associated with higher mortality rates and the likelihood of receiving less evidence-based treatment after stroke. In contrast, little is known about the impact of SES on recovery after discharge from inpatient rehabilitation. The aim of this study was to investigate the influence of SES on long-term recovery after stroke.

PATIENTS AND METHODS

In a prospective, observational, multicentre study, inpatients were recruited towards the end of rehabilitation. The 12-month follow-up focussed on upper limb motor recovery, measured by the Fugl-Meyer score. A clinically relevant improvement of ≥5.25 points was considered recovery. Patient-centric measures such as the Patient-reported Outcomes Measurement Information System-Physical Health (PROMIS-10 PH) provided secondary outcomes. Information on schooling, vocational training, income and occupational status pre-stroke entered a multidimensional SES index. Multivariate logistic regression models calculating odds ratios (ORs) and corresponding confidence intervals (CIs) were applied. SES was added to an initial model including age, sex and baseline neurological deficit. Additional exploratory analyses examined the association between SES and outpatient treatment.

RESULTS

One hundred and seventy-six patients were enrolled of whom 98 had SES and long-term recovery data. Model comparisons showed the SES-model superior to the initial model (Akaike information criterion (AIC): 123 vs. 120, Pseudo R²: 0.09 vs. 0.13). The likelihood of motor recovery (OR = 17.12, 95%CI = 1.31; 224.18) and PROMIS-10 PH improvement (OR = 20.76, 95%CI = 1.28; 337.11) were significantly increased with higher SES, along with more frequent use of outpatient therapy (p = .02).

CONCLUSIONS

Higher pre-stroke SES is associated with better long-term recovery after discharge from rehabilitation. Understanding these factors can improve outpatient long-term stroke care and lead to better recovery.KEY MESSAGEHigher pre-stroke socioeconomic status (SES) is associated with better long-term recovery after discharge from rehabilitation both in terms of motor function and self-reported health status.Higher SES is associated with significantly higher utilization of outpatient therapies.Discharge management of rehabilitation clinics should identify and address socioeconomic factors in order to detect individual needs and to improve outpatient recovery.

Task-Related Hemodynamic Changes Induced by High-Definition Transcranial Direct Current Stimulation in Chronic Stroke Patients: An Uncontrolled Pilot fNIRS Study

High-definition transcranial direct current stimulation (HD-tDCS) has recently been proposed as a tDCS approach that can be used on a specific cortical region without causing undesirable stimulation effects. In this uncontrolled pilot study, the cortical hemodynamic changes caused by HD-tDCS applied over the ipsilesional motor cortical area were investigated in 26 stroke patients. HD-tDCS using one anodal and four cathodal electrodes at 1 mA was administered for 20 min to C3 or C4 in four daily sessions. Cortical activation was measured as changes in oxyhemoglobin (oxyHb) concentration, as found using a functional near-infrared spectroscopy (fNIRS) system during the finger tapping task (FTT) with the affected hand before and after HD-tDCS. Motor-evoked potential and upper extremity functions were also measured before (T0) and after the intervention (T1). A group statistical parametric mapping analysis showed that the oxyHb concentration increased during the FTT in both the affected and unaffected hemispheres before HD-tDCS. After HD-tDCS, the oxyHb concentration increased only in the affected hemisphere. In a time series analysis, the mean and integral oxyHb concentration during the FTT showed a noticeable decrease in the channel closest to the hand motor hotspot (hMHS) in the affected hemisphere after HD-tDCS compared with before HD-tDCS, in accordance with an improvement in the function of the affected upper extremity. These results suggest that HD-tDCS might be helpful to rebalance interhemispheric cortical activity and to reduce the hemodynamic burden on the affected hemisphere during hand motor tasks. Noticeable changes in the area adjacent to the affected hMHS may imply that personalized HD-tDCS electrode placement is needed to match each patient’s individual hMHS location.
