Abstract
Stroke is a cerebrovascular disease that impairs blood supply to localized brain tissue regions due to various causes. This leads to ischemic and hypoxic lesions, necrosis of the brain tissue, and a variety of functional disorders. Abnormal cortical activation and functional connectivity occur in the brain after a stroke, but the activation patterns and functional reorganization are not well understood. Rehabilitation interventions can enhance functional recovery in stroke patients. However, clinicians require objective measures to support their practice, as outcome measures for functional recovery are based on scale scores. Furthermore, the most effective rehabilitation measures for treating patients are yet to be investigated. Functional near-infrared spectroscopy (fNIRS) is a non-invasive neuroimaging method that detects changes in cerebral hemodynamics during task performance. It is widely used in neurological research and clinical practice due to its safety, portability, high motion tolerance, and low cost. This paper briefly introduces the imaging principle and the advantages and disadvantages of fNIRS to summarize the application of fNIRS in post-stroke rehabilitation.

Differences in Improvement of Physical Function in Older Adults with Long-Term Care Insurance with and without Falls: A Retrospective Cohort Study. Healthcare (Basel) 2023; 11:2558. [PMID: 37761755 PMCID: PMC10531465 DOI: 10.3390/healthcare11182558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 09/04/2023] [Accepted: 09/13/2023] [Indexed: 09/29/2023] Open
Abstract
(1) Background: This study examined the differences in changes in physical function with and without falls after daycare use among frail older adults with long-term care insurance (LTCI). (2) Methods: In this retrospective cohort study, 82 of 96 consecutive daycare center users met the inclusion criteria. The participants were divided into two groups based on the presence or absence of falls 6-12 months after use. Participant characteristics in the fall and non-fall groups and physical function at baseline and six months in each group were compared. Using analysis of covariance, we analyzed physical function and its changes between the two groups, and cut-off values were calculated using receiver operating characteristic curves. (3) Results: Gait speed, timed up-and-go test, and 30 s chair stand test (CS30) improved significantly over six months in the no-fall group (n = 70) and all participants (n = 82) (p < 0.01). Gait speed in the fall group (n = 12) improved significantly over six months (p = 0.04). The fall group had significantly lower adjusted ΔCS30 scores than the no-fall group (p = 0.03), with a cutoff value of 2 (p = 0.024). (4) Conclusions: In older adults with LTCI, physical function with and without falls after daycare use differed by ΔCS30, with a cutoff value of 2.

A validity study to consult on a protocol of a home hazard management program for falls prevention among community dwelling stroke survivors. PLoS One 2023; 18:e0279657. [PMID: 36630460 PMCID: PMC9833545 DOI: 10.1371/journal.pone.0279657] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Accepted: 12/11/2022] [Indexed: 01/12/2023] Open
Abstract
OBJECTIVE A fall after a stroke is common but the consequences can be devastating not only for the stroke survivors, but also for caregivers, healthcare, and the society. However, research on falls prevention among the stroke population are limited, particularly on home hazards assessment and home modifications, demanding for a study to be conducted. The aim of the study is to validate the protocol and content of a home hazard management program guided by the Person-Environment-Occupation (PEO) Model for falls prevention among community dwelling stroke survivors. METHOD Researchers developed their own questionnaire for content validation which consist of 23 items that covers two domains, namely justification for telehealth home hazard management practice and the protocol's overall methodology. Occupational therapists with at least one year of experience in conducting a home hazard assessment were consulted for the content validation of a two-group clinical controlled trial protocol utilizing a home hazard assessment, home modifications and education over the usual care. Written consent was obtained prior to the study. The occupational therapists were given a Google Form link to review the protocol and intervention based on the questionnaire and rated each item using a four-point Likert scale for relevance and feasibility. Open-ended feedback was also recorded on the google form. Content Validity Index (CVI), Modified Kappa Index and Cronbach's Alpha was calculated for the content validity and reliability analysis. RESULTS A total of sixteen occupational therapists participated in the study. 43.7% of participants had a master's degree, 93.7% worked in the government sector and 56.2% had six years and more experience on conducting home hazard assessments. Content validity of the protocol is satisfactory for relevancy and feasibility (CVI = 0.84, ranging from 0.5 to 1.00), and for the reliability (α = 0.94 (relevance) and α = 0.97 (feasibility), respectively. The Modified Kappa ranged from 0.38 to 1.00 for all items. Feedback was also received regarding the design and procedure of the study protocol which included participant's selection criteria, sample size, equipment provided, cost, location, and care for the participants during the intervention. CONCLUSIONS Introducing a home hazard management program to prevent falls among the stroke population is viewed relevant and feasible. Practical suggestions from the consultation panel were adopted, and minor adjustments were required to strengthen the protocol's overall methodology. This study established a rigorous and robust experimental protocol for future undertaking.

Abstract
We aimed to identify determinants in acute stroke that are associated with falls during the stroke unit stay. In order to enable individualized preventive actions, this knowledge is fundamental. Based on local and national quality register data on an unselected sample of 5065 stroke patients admitted to a stroke unit at a Swedish university hospital, univariable and multivariable logistic regression analyses were performed. The dependent variable was any fall during stroke unit stay. The independent variables related to function, activity, personal factors, time to assessment, comorbidities and treatments. Determinants of falls were: being male (odds ratio (OR) 2.25, 95% confidence interval (95% CI) 1.79–2.84), haemorrhagic stroke (OR 1.39, 95% CI 1.05–1.86), moderate stroke symptoms according to the National Institutes of Health Stroke Scale (NIHSS score 2–5 vs. NIHSS score 0–1) (OR 1.43, 95% CI 1.08–1.90), smoking (OR 1.70, 95% CI 1.29–2.25), impaired postural control in walking (OR 4.61, 95% CI 3.29–6.46), impaired postural control in standing (OR 1.60, 95% CI 1.25–2.05), stroke-related arm- and hand problems, OR 1.45, 95% CI 1.11–1.91), impaired cognition (OR 1.43, 95% CI 1.04–1.95), and urinary tract infection (OR 1.91, 95% CI 1.43–2.56). The findings from this study are useful in clinical practice and might help to improve patient safety after stroke.

Abstract
OBJECTIVE To identify the occurrence of recurrent falls and the determinants in the acute phase poststroke that are associated with recurrent falls within the first year poststroke. DESIGN Prospective follow-up study. SETTING Stroke unit and community. PARTICIPANTS Patients (N=504) with acute stroke. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The dependent variable was recurrent falls, defined as ≥2 falls, within the first year poststroke. The independent baseline variables were related to function, activity, participation, personal and environmental factors, and comorbidity and were assessed within 4 days after admission to a stroke unit. Fall data were registered at the stroke unit, and self-reported fall data were collected during follow-up using a standardized questionnaire. Determinants of recurrent falls were identified using univariable and multivariable logistic regression analyses. RESULTS Within 12 months poststroke, 95 of 348 participants (27%) had experienced recurrent falls. Poor postural control (odds ratio [OR] 5.85; 95% confidence interval [CI], 2.84-12.02; P<.0001), moderate postural control (OR 2.41; 95% CI, 1.21-4.80; P=.012), and using a walking aid in the acute phase (OR 2.51; 95% CI, 1.45-4.36; P=.0010) are statistically significant determinants that are associated with recurrent falls within the first year poststroke. The determinant of using a walking aid appears to be primarily driven by those younger than 80 years. In addition to impaired postural control and using a walking aid, a fall at the stroke unit is a determinant associated with recurrent falls after discharge within 6 months poststroke. CONCLUSIONS More than 1 in 4 individuals with stroke experienced recurrent falls within the first year poststroke. Impaired postural control, using a walking aid in the acute phase, and fall during hospitalization are determinants associated with recurrent falls during follow-up. The determinants differ somewhat at different ages.

Abstract
OBJECTIVE: To identify the incidence of falls and factors present shortly after stroke, which are associated with the occurrence of falls over the first 12 months after stroke onset, following discharge from inpatient rehabilitation. DESIGN: Prospective follow-up study. SETTING: Stroke unit and outpatient department. SUBJECTS: A total of 490 individuals with acute stroke. METHODS: Postural control was assessed using the Swedish modified version of the Postural Assessment Scale for Stroke Patients. Data on self-reported falls were collected using a standardized questionnaire at three months after discharge and six and 12 months after stroke onset. Associations between characteristics during the acute phase after a stroke and falls after six and 12 months were investigated using univariable and multivariable regression analyses. MAIN MEASURES: The endpoint was a self-reported fall. RESULTS: Within three months after discharge, 38 of 165 respondents (23%) had experienced at least one fall. Within six and 12 months after stroke onset, respectively, 108 of 376 (29%) and 140 of 348 (40%) of the respondents had experienced at least one fall. Poor postural control (odds ratio 3.92, 95% confidence interval 2.07-7.45, P < 0.0001) and using a walking aid (odds ratio 2.84, 95% confidence interval 1.71-4.72, P < 0.0001) were predictors of falls after discharge within 12 months after stroke onset. The same variables were independent predictors of falls within six months. CONCLUSION: Poor postural control and using a walking aid in the acute phase after a stroke are associated with falls after discharge from a stroke unit within 12 months after stroke onset.
