Predictors of Multidimensional Profiles of Participation After Traumatic Brain Injury: A TBI Model Systems Study.

To identify personal, clinical, and environmental factors associated with 4 previously identified distinct multidimensional participation profiles of individuals following traumatic brain injury (TBI). Community. Participants (n = 408) enrolled in the TBI Model Systems (TBIMS) Participation Module, all 1 year or more postinjury. Secondary data analysis of cross-sectional data from participants in a multicenter TBIMS module study on participation conducted between May 2006 and September 2007. Participants provided responses to questionnaires via a telephone interview at their study follow-up (1, 2, 5, 10, or 15 years postinjury). Participants provided responses to personal (eg, demographic), clinical (eg, function), environmental (eg, neighborhood type), and participation measures to create multidimensional participation profiles. Data from measures collected at the time of injury (preinjury questionnaire, injury characteristics) were also included. The primary outcome was assignment to one of 4 multidimensional participation profile groups based on participation frequency, importance, satisfaction, and enfranchisement. The measures used to develop the profiles were: Participation Assessment with Recombined Tools-Objective, Importance, and Satisfaction scores, each across 3 domains (Productivity, Social Relationships, Out and About in the Community) and the Enfranchisement Scale (contributing to one's community, feeling valued by the community, choice and control). Results of the multinomial regression analysis, with 4 distinct participation profile groups as the outcome, indicated that education, current employment, current illicit drug use, current driving status, community type, and Functional Independence Measure Cognitive at follow-up significantly distinguished participation profile groups. Findings suggest a trend toward differences in participation profile groups by race/Hispanic ethnicity. Understanding personal, clinical, and environmental factors associated with distinct participation outcome profiles following TBI may provide more personalized and nuanced guidance to inform rehabilitation intervention planning and/or ongoing clinical monitoring.

Improving Neuroplasticity through Robotic Verticalization Training in Patients with Minimally Conscious State: A Retrospective Study.

In disorders of consciousness, verticalization is considered an effective type of treatment to improve motor and cognitive recovery. Our purpose is to investigate neurophysiological effects of robotic verticalization training (RVT) in patients with minimally conscious state (MCS). Thirty subjects affected by MCS due to traumatic or vascular brain injury, attending the intensive Neurorehabilitation Unit of the IRCCS Neurolesi (Messina, Italy), were included in this retrospective study. They were equally divided into two groups: the control group (CG) received traditional verticalization with a static bed and the experimental group (EG) received advanced robotic verticalization using the Erigo device. Each patient was evaluated using both clinical scales, including Levels of Cognitive Functioning (LCF) and Functional Independence Measure (FIM), and quantitative EEG pre (T0) and post each treatment (T1). The treatment lasted for eight consecutive weeks, and sessions were held three times a week, in addition to standard neurorehabilitation. In addition to a notable improvement in clinical parameters, such as functional (FIM) (p < 0.01) and cognitive (LCF) (p < 0.01) outcomes, our findings showed a significant modification in alpha and beta bands post-intervention, underscoring the promising effect of the Erigo device to influence neural plasticity and indicating a noteworthy difference between pre-post intervention. This was not observed in the CG. The observed changes in alpha and beta bands underscore the potential of the Erigo device to induce neural plasticity. The device's custom features and programming, tailored to individual patient needs, may contribute to its unique impact on brain responses.

Disparities between Native Americans and Whites in trajectories of functional independence and life satisfaction over the 5 years after traumatic brain injury.

Traumatic brain injury (TBI) can lead to impairments in motor and cognitive function and reduced life satisfaction. TBI is one of the leading causes of death and disability worldwide and disproportionately affects Native Americans, who have the highest rates of TBI among all races in the United States and elevated likelihood for fatality and severe complications. This study investigated whether disparities in functional and life satisfaction outcomes exist longitudinally over the 5 years after complicated mild, moderate, or severe TBI between Native Americans and White individuals; it further explored which demographic and injury-related covariates account for them. The current study used a subsample of the national TBI Model Systems Database of 80 demographically and injury-severity matched Native American and White pairs (total n = 160). A series of longitudinal hierarchical linear models found that Native Americans experienced significantly lower Functional Independence Measure Cognitive and Motor trajectories than Whites; however, life satisfaction was comparable. Native Americans had declining cognitive function over time relative to a slight increase in White individuals. This differential movement dissipated with the addition of employment status at the time of injury and type of health insurance. These results demonstrate a profound need to further investigate the cultural and contextual variables unique to Native Americans that underlie these differences and highlight the importance of culturally responsive treatment and rehabilitation in bridging the gap in recovery.

Prognostic Value of Dysphagia for Activities of Daily Living Performance and Cognitive Level after Stroke.

The purpose of this study was to examine the association between baseline dysphagia and the improvement of activities of daily living performance and cognitive level among inpatients after stroke. This was a retrospective cohort study of patients undergoing convalescent rehabilitation after stroke. Dysphagia was assessed using the Food Intake LEVEL Scale. Outcomes were the motor and cognitive scores of the Functional Independence Measure (FIM) at discharge. Multiple regression analysis was performed to examine the association between dysphagia at admission and these outcomes. There were 499 participants with a median age of 74 years. A multiple regression analysis was carried out after adjusting for potential confounders including age and sex. Dysphagia at admission was independently and negatively associated with motor (β=-0.157, P<0.001) and cognitive (β=-0.066, P=0.041) FIM scores at discharge. Baseline dysphagia in patients after stroke was negatively associated with improvement in performance of activities of daily living and cognitive level.

The association between inpatient rehabilitation intensity and outcomes after stroke in Ontario, Canada.

Several studies have demonstrated improved outcomes poststroke when higher intensity rehabilitation is provided. Canadian Stroke Best Practice Recommendations advise patients receive 180 min of therapy time per day; however, the exact amount required to reach benefit is unknown. The primary aim of this study was to determine the association between rehabilitation intensity (RI) and total Functional Independence Measure (FIM) Instrument change. Secondary aims included determining the association between RI and discharge location, 90-day home time, rehabilitation effectiveness, and motor and cognitive FIM change. A retrospective cohort study was conducted using available administrative databases of acute stroke patients discharged to inpatient rehabilitation facilities in Ontario, Canada, from January 2017 to December 2021. RI was defined as number of minutes per day of direct therapy by all providers divided by rehabilitation length of stay. The association between RI and the outcomes of interest were analyzed using regression models with restricted cubic splines. A total of 12,770 individuals were included. Mean age of the sample was 72.6 years, 46.0% of individuals were female, and 87.6% had an ischemic stroke. Mean RI was 74.7 min (range: 5-162 min) per day. Increased RI was associated with an increase in mean FIM change. However, there was diminishing incremental increase after reaching 95 min/day. Increased RI was positively associated with motor and cognitive FIM change, rehabilitation effectiveness, 90-day home time, and discharge to preadmission setting. Higher RI was associated with a lower likelihood of discharge to long-term care. None of the patients met the recommended RI of 180 min/day based on the Canadian Stroke Best Practice Recommendations. Despite this, higher intensity was associated with better outcomes. Given that most positive associations were observed with a RI ⩾95 min/day, this may be a more feasible target.

Association between tongue pressure and oral status and activities of daily living in stroke patients admitted to a convalescent rehabilitation unit.

Clarifying how tongue pressure in convalescent stroke patients affects oral condition andactivities of daily living (ADL) is important for developing oral rehabilitation programs and for rehabilitation care to reacquire ADL. To clarify how tongue pressure is associated with oral status, ADL, and nutritional status in stroke patients. Sixty-eight patients aged 77.9 ± 10.0 years participated. The Japanese version of the Oral Health Assessment Tool was used to evaluate oral status. Data such as the ADL index functional independence measure (FIM), nutritional intake method, serum albumin, and body mass index were extracted from medical records. To examine factors associated with tongue pressure, multiple regression analysis was performed adjusting for confounding factors. The level of statistical significance was set at p < .05. In recovery phase stroke patients, tongue pressure was significantly lower in the total assistance group than in the partial assistance/independent group. In addition, tongue pressure was significantly lower in tube feeding patients than in oral feeding patients. FIM cognition score was an independent factor that had a significant effect on tongue pressure. These findings suggest that ADL status also affects tongue pressure, thus patients' ADL including the FIM cognition subscale should also be evaluated while measuring tongue pressure.

4 The Role of Cognition and Self-Awareness on Driving Patterns After Moderate-to-Severe Traumatic Brain Injury

Objective:Return to driving after moderate-to-severe traumatic brain injury (TBI) is often a key step in recovery to regain independence. Survivors are often eager to resume driving and may do so despite having residual cognitive limitations from their injury. A better understanding is needed of how cognition and self-awareness impact survivors’ driving after injury. This study examined the influence of cognition and self-awareness on driving patterns following moderate-to-severe TBI.Participants and Methods:Participants were 350 adults aged 19-87 years (mean age = 46 years; 70% male) with history of moderate-to-severe TBI, who resumed driving and were enrolled in the TBI Model System. Cross-sectional data were obtained ranging 1-30 years post injury, including questions on driving practices, the Brief Test of Adult Cognition by Telephone (BTACT), and the Functional Independence Measure (FIM). Self-awareness of cognitive function was measured via the discrepancy between dichotomized ratings (intact versus impaired) of objective cognitive testing (BTACT) and self-reported cognitive function (FIM Cognition subscale). Driving patterns included frequency (driving 'more than once a week’ versus 'once a week or less') and restricted driving behavior (total number of driving situations the survivor described as restricted, ranging 0-15). Regression analyses were conducted to examine the relationships between cognition, self-awareness, and each driving outcome (frequency and restriction), followed by causal mediation analyses to examine the mediating effect of self-awareness. Demographics (age, sex, education), injury characteristics (time since injury, injury severity, history of seizures in past year), and medical/social factors (family income, motor function, urban-rural classification) were included in the models as covariates.Results:Thirty-nine percent of survivors had impaired self-awareness, 88% of survivors drove numerous times per week, and the average survivor reported limited driving in 6 situations (out of 15 total situations). Cognition was inversely related to impaired self-awareness (OR = 0.03, p &lt; 0.001) and inversely related to restricted driving behavior (b = -0.79, p &lt; 0.001). Motor function was positively related to impaired self-awareness (OR = 1.28, p &lt; 0.01). Cognition was not related to driving frequency, and self-awareness did not mediate the relationships between cognition and driving patterns (all p &gt; 0.05).Conclusions:Most survivors who drive after their injury are driving frequently, but the situations they drive in differ based on their cognitive ability. Impaired self-awareness of cognitive deficits is common after TBI, and self-awareness of cognitive function does not affect driving patterns. Future research needs to focus on how cognition affects nuanced aspects of driving behavior after injury (i.e., types of situations survivors drive in).

Correlates of Longitudinal Trajectories of Depressive Symptoms in Adolescents With Traumatic Brain Injuries.

Depression poses a significant threat to the health and well-being of adolescents with traumatic brain injury. Existing research has limitations in longitudinal follow-up period, consideration of sample heterogeneity, and outcome measurement modeling. This study aimed to address these gaps by applying the second-order growth mixture model (SO-GMM) to examine the 10-year post-injury depression trajectories in adolescents with TBI. A total of 1,989 adolescents with TBI 16-21 years old from the Traumatic Brain Injury Model System National Data Bank were analyzed up to 10 years post-injury. Depressive symptoms were measured by Patient Health Questionnaire-9. Covariates included age, sex, race/ethnicity, employment, Functional Independence Measure Cognition, TBI severity, pre-injury disability, and substance use. Longitudinal measurement invariance was tested at the configural, metric, and scalar levels before SO-GMM was fit. Logistic regression was conducted for disparities in depression trajectories by covariates. A 2-class SO-GMM was identified with a low-stable group (85% of the sample) and a high-increasing group (15% of the sample) on depression levels. Older age, being a Native American, and having Hispanic origin was associated with a higher likelihood of being in the high-increasing class (odds ratios [ORs] = 1.165-4.989 and 1.609, respectively), while patients with higher education and being male were less likely to be in the high-increasing class (ORs = 0.735 and 0.557, respectively). This study examined the disparities in depression among two distinct longitudinal groups of adolescents with TBI 10 years post-injury. Findings of the study are informative for intervention development to improve long-term mental health in adolescents with TBI.

Clinical efficacy of assessment of swallowing ability for pneumonia and other assessment tools for occurrence and mortality from pneumonia among older inpatients in a long-term care hospital

BackgroundAspiration pneumonia is an important condition in elderly patients and detecting dysphagia early can help clinicians identify patients with a high risk of aspiration pneumonia. We previously reported the usefulness of the Assessment of Swallowing Ability for Pneumonia (ASAP) in predicting the occurrence of and mortality from pneumonia in patients in acute care hospitals; however, there are very few reports on the utility of this screening test for patients in stable condition. MethodsElderly patients in stable condition (n = 133) without pneumonia were prospectively enrolled. Associations between ASAP, Functional Independence Measure (FIM), Controlling Nutrition Status (CONUT), and Charlson Co-morbidity Index (CCI) scores and occurrence of/mortality from pneumonia during hospitalization were evaluated. ResultsThe occurrence of pneumonia was observed in 27 (20.3%) patients, and 18 (13.5%) died during hospitalization. Multivariate analysis showed that low ASAP score and low FIM motor were independent predictors for the occurrence of pneumonia, and low ASAP score was an independent predictor for mortality from pneumonia. Areas under the curve for ASAP, FIM motor, FIM cognition, and CONUT scores were 0.895 (95% confidence interval [CI], 0.829–0.960), 0.913 (95% CI, 0.860–0.968), 0.841 (95% CI, 0.761–0.921), and 0.753 (95% CI, 0.649–0.858), respectively, for occurrence, and 0.881 (95% CI, 0.807–0.955), 0.904 (95% CI, 0.860–0.949), 0.829 (95% CI, 0.727–0.931), 0.746 (95% CI, 0.617–0.874), respectively, for mortality. ConclusionThe ASAP and FIM motor are useful for predicting the occurrence of and mortality from pneumonia in elderly inpatients in long-term care hospitals.

The impact of dementia on rehabilitation outcomes following hip fracture.

To compare clinical outcomes between patients for whom their participation in inpatient rehabilitation was and was not impacted by dementia through matching patients reporting dementia (dementia group) with those not reporting dementia (non-dementia group). Prospectively collected data held by the Australasian Rehabilitation Outcome Centre (AROC) were analyzed for patients aged 65 years or older receiving inpatient rehabilitation in public hospitals in Australia following a hip fracture and discharged between July 1, 2014, and June 30, 2019. Patients reported as having dementia impacting their rehabilitation program were matched to patients not reporting dementia based on age, admission motor Functional Independence Measure (FIM) score, and accommodation prior to rehabilitation. The matched cohorts were compared in relation to clinical outcomes (motor and cognitive FIM improvement, FIM efficiency, length of stay, and discharge destination) following participation in hospital-based rehabilitation using univariate analysis. Patients with dementia had significantly lower cognitive FIM scores on commencing rehabilitation (17.6 and 26.9, respectively, P < 0.001) and their median length of stay was 2 days shorter than those without dementia (21 and 23 days, respectively, P < 0.001). Relative change in FIM score and FIM efficiency (per week) were lower in the dementia group [relative FIM score change of dementia vs non-dementia, respectively, 26.2% vs. 44.0% (P < 0.001) and FIM efficiency, 6.5 vs. 8.9 (P < 0.001)]. Discharge destination between the two groups was statistically different, with 35.7% of patients with dementia being discharged to residential aged care facilities (RACFs) compared to 21.7% of those without dementia (P < 0.001). More patients with dementia had carers in their private residence in the post-rehabilitation phase, 82.2% vs. 57.6% (P < 0.001). Patients with dementia who sustain a fractured hip benefit from inpatient rehabilitation, although their clinical outcomes are not as good as those without dementia. FIM change and FIM efficiency were lower in the dementia group. Length of stay in the hospital for patients with dementia was shorter due to earlier recognition for the need for placement in either an RACF or at home with carer support. Theneed for placement in an RACF or carer support in a private residence was significantly greater in the dementia group.

Exploring racial/ethnic disparities in rehabilitation outcomes after TBI: A Veterans Affairs Model Systems study.

Almost one-third of the U.S. military population is comprised of service members and veterans (SMVs) of color. Research suggests poorer functional and psychosocial outcomes among Black and Hispanic/Latine vs. White civilians following traumatic brain injury (TBI). This study examined racial/ethnic differences in 5-year functional independence and life satisfaction trajectories among SMVs who had undergone acute rehabilitation at one of five Veterans Affairs (VA) TBI Model Systems (TBIMS) Polytrauma Rehabilitation Centers (PRCs). Differences in demographic and injury-related factors were assessed during acute rehabilitation among White (n = 663), Black (n = 89), and Hispanic/Latine (n = 124) groups. Functional Independence Measure (FIM) Motor, FIM Cognitive, and Satisfaction with Life Scale (SWLS) scores were collected at 1, 2, and 5 years after injury. Racial/ethnic comparisons in these outcome trajectories were made using hierarchical linear modeling. Black SMVs were less likely than White and Hispanic/Latine SMVs to have been deployed to a combat zone; there were no other racial/ethnic differences in any demographic or injury-related variable assessed. In terms of outcomes, no racial/ethnic differences emerged in FIM Motor, FIM cognitive, or SWLS trajectories. The absence of observable racial/ethnic differences in 5-year outcome trajectories after TBI among SMVs from VA TBIMS PRCs contrasts sharply with previous research identifying disparities in these same outcomes and throughout the larger VA health care system. Individuals enrolled in VA PRCs are likely homogenized on key social determinants of health that would otherwise contribute to racial/ethnic disparities in outcome trajectories.

Prism Adaptation Treatment for Right-Sided and Left-Sided Spatial Neglect: A Retrospective Case-Matched Study

ObjectiveTo compare the effectiveness of prism adaptation treatment (PAT) between patients with right- and left-sided spatial neglect (SN). DesignRetrospective case-matched design. SettingInpatient rehabilitation hospitals and facilities. ParticipantsA total of 118 participants were selected from a clinical dataset of 4256 patients from multiple facilities across the United States. Patients with right-sided SN (median age: 71.0 [63.5-78.5] years; 47.5% female; 84.8% stroke, 10.1% traumatic/nontraumatic brain injury) were matched 1:1 with patients with left-sided SN (median age: 70.0 [63.0-78.0] years; 49.2% female; 86.4% stroke, 11.8% traumatic/nontraumatic brain injury) based on age, neglect severity, overall functional ability at admission, and number of PAT sessions completed during their hospital stay. InterventionPrism adaptation treatment. Main Outcome MeasuresPrimary outcomes were pre–post change on the Kessler Foundation Neglect Assessment Process (KF-NAP) and the Functional Independence Measure (FIM). Secondary outcomes were whether the minimal clinically important difference was achieved for pre–post change on the FIM. ResultsWe found greater KF-NAP gain for patients with right-sided SN than those with left-sided SN (Z = 2.38, P=.018). We found no differences between patients with right-sided and left-sided SN for Total FIM gain (Z=–0.204, P=.838), Motor FIM gain (Z=–0.331, P=.741), or Cognitive FIM gain (Z=–0.191, P=.849). ConclusionsOur findings suggest PAT is a viable treatment for patients with right-sided SN just as it is for patients with left-sided SN. Therefore, we suggest prioritizing PAT within the inpatient rehabilitation setting as a treatment to improve SN symptoms regardless of brain lesion side.

Negative impact of behavior restriction amidst a clustered COVID-19 infection on immobility syndrome in older patients negative for COVID-19: report from a chronic care hospital in Japan.

Previous studies have reported on associations between immobility syndrome and the COVID-19 pandemic. However, little is known about the aggravation of this syndrome in older patients negative for COVID-19 infection amidst behavior restriction due to a clustered COVID-19 infection. Patients hospitalized one month before a clustered COVID-19 infection occurred in our hospital were recruited. Rehabilitation therapy was suspended for 25 days during behavior restriction. The ability of daily living of the patients was evaluated with the functional independence measure and Barthel index. Chronological changes in the functional independence measure and Barthel index scores were evaluated monthly, beginning one month before the clustered COVID-19 infection to one month after re-initiation of rehabilitation therapy. Patients with minimum scores in the functional independence measure (18) and Barthel index (0) prior to the clustered COVID-19 infection were excluded. Functional independence measure scores of 73 older patients and the Barthel index scores of 48 patients were analyzed. The mean total functional independence measure score amidst the behavior restriction significantly changed from 36.3 to 35.1 (p = 0.019), while statistical significance was not detected in the mean motor subtotal (from 21.6 to 20.9 with p = 0.247) or cognitive subtotal functional independence measure scores (from 14.6 to 14.2 with p = 0.478). During the behavior restriction, the mean Barthel index scores declined from 25.8 to 23.2 without statistical significance (p = 0.059). Behavior restriction due to a clustered COVID-19 infection may aggravate immobility syndrome in older patients who are negative for COVID-19.

Abstract WMP33: Cognitive Outcomes In Patients With A Prior History Of Stroke Participating In Inpatient Rehabilitation

Introduction: We sought to investigate the impact of prior stroke on cognitive improvement in stroke patients participating in inpatient rehabilitation. Methods: This was a retrospective review of clinical data from inpatient stroke rehabilitation (ISR) units collected from 09/2017- 08/2019. Age at onset, stroke type (ischemic or intracerebral hemorrhage (ICH)), therapy days, sex, and past medical history of stroke, diabetes, hypertension (HTN) were extracted as predictors of outcome in ISR. The baseline level of disability upon admission to acute stroke care was accounted for with pre-morbid modified Rankin scale (mRS) score and initial NIH Stroke Scale (NIHSS). The outcome variable of interest was total discharge cognitive functional independence measure (TDC-FIM) from ISR. FIM admission to ISR was controlled for in the model. Results: The data of 681 patients were used in a Lasso regression analysis (Figure 1), and of these patients there were 202 patients with a history of prior stroke. Univariate analysis showed a significant difference between prior stroke and first-time stroke groups with respect to pre-morbid mRS (p&lt;0.001), initial NIHSS (p = 0.003), HTN (p=0.004), and stroke type (p=0.023). Lasso regression indicated that patients with diabetes had a 0.58 point decrease in TDC-FIM while those with HTN had a 0.38 point decrease as compared to patients who did not have these vascular risk factors. Patients with ischemic stroke type had a 0.73 point decrease in the TDC-FIM as compared to those who had an ICH. Prior stroke and the patient’s sex had no effect on TDC-FIM. The R-squared of the model was 0.74. Conclusion: By controlling for vascular risk factors, our findings show no difference in TDC-FIM with respect to prior stroke. This is different from prior studies that found prior stroke was associated with worse cognitive outcomes at discharge from ISR. Our results indicate that managing HTN and diabetes is imperative for post-stroke cognitive rehabilitation

Correlations between disease severity and rehabilitation outcomes in patients recovering from covid-19 infection.

Based on long-term follow-up of patients with COVID-19, to evaluate whether the severity of acute COVID-19 infection affects rehabilitation outcomes. Observational cohort study. A total of 61 post-acute COVID-19 patients underwent inpatient and outpatient customized rehabilitation treatment. The severity of acute COVID-19 infection was measured with the World Health Organization Clinical Progression Scale (WHO-CPS). Motor, cognitive, and functional variables were measured using standard and specified scales 6 months or more after acute illness. Of the 61 subjects, 65.6% had severe disease according to WHO-CPS. Significant improvement was found in activities of daily living functions (Functional Independence Measure (FIM) at admission 103.7 ± 18.9 vs FIM at discharge 118.7 ± 6.8) (p < 0.00). Of participants, 88% were able to wean off oxygen completely. A significant correlation was found between higher WHO-CPS, prolonged acute hospitalization, and days of ventilation on the one hand, and lower total and motor FIM at admission, but not with cognitive FIM or Montreal Cognitive Assessment (MoCA). No correlation was found between these parameters and functional level at discharge. The severity of acute COVID-19 infection affects the functional status of survivors at admission to rehabilitation, but, contrary to expectations, not the functional outcomes at discharge. These findings emphasize the importance of customized multidisciplinary rehabilitation programmes for improving the daily functioning and wellbeing of patients with severe COVID-19.

Predicting length of stay with assessment of motor and process skills in subjects with acquired brain injury

ABSTRACT Background The Functional Independence Measure (FIM) is a well-established predictor of length of stay (LOS) for rehabilitation. The Assessment of Motor and Process Skills (AMPS) is a more in-depth construct for measuring activities of daily living (ADL) and may therefore be a valuable adjunct when predicting LOS. This paper aimed to investigate AMPS as a candidate predictor of LOS in a statistical model including FIM. Methods A cohort study of 647 patients with acquired brain injuries admitted for rehabilitation. LOS was analyzed in a multiple regression model with the motor and process/cognitive domains of AMPS and FIM. Results Independence in ADL process ability and FIM cognition were associated with 31% (p < 0.001) and 38% (p < 0.001) shorter LOS, respectively, relative to patients needing total assistance. Independence in ADL motor ability was associated with a 26% (p = 0.002) shorter LOS, whereas FIM motor was not a predictor. Conclusions The AMPS predicts LOS for rehabilitation at a level that is at least as good as that of FIM. Conducting the AMPS early in the course of inpatient rehabilitation provides clinicians and managers with valuable information for planning LOS.

回復期リハビリテーション病棟における大腿骨転子部骨折患者の実績指数に影響を与える要因について

[Purpose] To identify factors affecting the performance index of trochanteric femoral fracture patients. [Participants and Methods] The participants were 117 patients with a trochanteric femoral fracture who underwent convalescent rehabilitation treatment. The relationships between the motor Functional Independence Measure (FIM) gain, length of a stay in the convalescent rehabilitation ward, and nine variables available at the time of admission to the convalescent rehabilitation ward were examined using Spearman’s rank correlation coefficient and multiple regression analysis using the stepwise method. [Results] The motor FIM score, the cognitive FIM score at the time of admission to the convalescent rehabilitation ward and pre-injury walking ability influenced motor FIM gain. No significant correlation was found for length of a stay in the convalescent rehabilitation ward. [Conclusion] The higher the three variables described above as influencing motor FIM gains were, the higher the FIM gains were, especially those of bathtub transfers and movement on stairs.

Prognosis of Individual-Level Mobility and Self-Care Stroke Recovery During Inpatient Rehabilitation, Part 1: A Proof-of-Concept Single Group Retrospective Cohort Study

ObjectiveTo demonstrate feasibility of generating predictive short-term individual trajectory recovery models after acute stroke by extracting clinical data from an electronic medical record (EMR) system. DesignSingle-group retrospective patient cohort design. SettingStroke rehabilitation unit at an independent inpatient rehabilitation facility (IRF). ParticipantsCohort of 1408 inpatients with acute ischemic or hemorrhagic stroke with a mean ± SD age of 66 (14.5) years admitted between April 2014 and October 2019 (N=1408). InterventionsNot applicable. Main Outcome Measures0-100 Rasch-scaled Functional Independence Measure (FIM) Mobility and Self-Care subscales. ResultsUnconditional models were best-fit on FIM Mobility and Self-Care subscales by spline fixed-effect functions with knots at weeks 1 and 2, and random effects on the baseline (FIM 0-100 Rasch score at IRF admission), initial rate (slope at time zero), and second knot (change in slope pre-to-post week 2) parameters. The final Mobility multivariable model had intercept associations with Private/Other Insurance, Ischemic Stroke, Serum Albumin, Motricity Index Lower Extremity, and FIM Cognition; and initial slope associations with Ischemic Stroke, Private/Other and Medicaid Insurance, and FIM Cognition. The final Self-Care multivariable model had intercept associations with Private/Other Insurance, Ischemic Stroke, Living with One or More persons, Serum Albumin, and FIM Cognition; and initial slope associations with Ischemic Stroke, Private/Other and Medicaid Insurance, and FIM Cognition. Final models explained 52% and 27% of the variance compared with unconditional Mobility and Self-Care models. However, some EMR data elements had apparent coding errors or missing data, and desired elements from acute care were not available. Also, unbalanced outcome data may have biased trajectories. ConclusionsWe demonstrate the feasibility of developing individual-level prognostic models from EMR data; however, some data elements were poorly defined, subject to error, or missing for some or all cases. Development of prognostic models from EMR will require improvements in EMR data collection and standardization.

Stroke impairment, balance, and cognitive status on admission predict walking independence up to 90 days post-stroke but their contributions change over time.

This study aimed to identify predictors of gait independence in three successive patient cohorts that received inpatient rehabilitation for at least 30 days, 60 days, or 90 days post-stroke. A total of 26 independent variables were collected within 3 days of stroke onset, including basic information (age, sex, stroke type), sensorimotor function (Stroke Impairment Assessment Set), gait function, balance function, and cognitive function. The dependent variable was walking independence (without assistance from another person) at 30, 60, or 90 days post-stroke. A decision tree was developed for predicting gait independence at each assessment time point. The predictors of walking independence differed among the cohorts that received inpatient rehabilitation for at least 30, 60, and 90 days post-stroke. Specifically, the Short Form Berg Balance Scale score was in the higher layer and was a strong predictor of gait at all time points. The cognitive Functional Independence Measure progressed to the higher layer at later time points. The lower extremity motor function was an additional predictor in the 30-day cohort. For later cohorts, the predictive value of balance and cognitive function declined whereas the contribution of the paralyzed grip strength and trunk function increased. These results suggest that sensorimotor and cognitive function within 3 days of stroke can predict walking independence between 1 and 3 months post-stroke; however, the prognostic value of predictors varies among the patients who receive inpatient rehabilitation for shorter versus longer time.

Machine learning predicts improvement of functional outcomes in traumatic brain injury patients after inpatient rehabilitation.

Survivors of traumatic brain injury (TBI) have an unpredictable clinical course. This unpredictability makes clinical resource allocation for clinicians and anticipatory guidance for patients difficult. Historically, experienced clinicians and traditional statistical models have insufficiently considered all available clinical information to predict functional outcomes for a TBI patient. Here, we harness artificial intelligence and apply machine learning and statistical models to predict the Functional Independence Measure (FIM) scores after rehabilitation for traumatic brain injury (TBI) patients. Tree-based algorithmic analysis of 629 TBI patients admitted to a large acute rehabilitation facility showed statistically significant improvement in motor and cognitive FIM scores at discharge.
