Surgically managed traumatic spinal cord injury in Singapore: a descriptive study across two level one trauma centres

Study designCase SeriesObjectivesTo provide an updated understanding of the incidence of surgically managed Traumatic Spinal Cord Injury (TSCI) in Singapore and to identify factors affecting discharge disposition.SettingPatients were identified from two level one trauma centres in Singapore.MethodsAll patients who underwent surgical management for acute TSCI between January 2020 to December 2021 were included. Demographics, injury details, peri-operative condition, hospital length of stay (LOS) and discharge disposition were evaluated. The overall characteristics of TSCI were summarised using descriptive statistics. The difference between discharge destinations was compared using chi-square test or t test. Variables with p values < 0.3 were selected for multivariable analysis.ResultsForty-four patients were included. Median age was 65. The most common SCI aetiology was fall from standing height or less (54.6%). Accidents involving personal mobility devices, bicycles and motor vehicles made up the next largest group (20.5%). Thirty-nine cases (88.6%) involved the cervical region. There were two cases of inpatient mortality. Twenty-one patients (50%) were discharged home, 21 (50%) were discharged to a community hospital (CH) or nursing home (NH). The median LOS in an acute hospital was 41 days. Multivariable logistic regression analysis revealed that functional independence measure (FIM) score on discharge was an independent factor that influenced discharge disposition (p = 0.037).ConclusionA public health focus on falls prevention, the development of geriatric spinal rehabilitation programs, and the consideration of a national registry are recommended for the comprehensive management of TSCI in Singapore.

Segmental phase angles as predictors of functional recovery and activities of daily living in patients after stroke.

This study investigated the association between segmental phase angles and functional outcomes in patients after stroke, hypothesizing that increased segmental phase angle correlates with improved functional status. A retrospective cohort study of 1012 patients after stroke was conducted. Whole body and segmental phase angles were measured using bioelectrical impedance analysis within 3 days of admission. Our exposure of interest was segmental phase angle measured via a multifrequency bioelectrical impedance analyzer and calculated as phase angle = arctangent (Xc/R) × (180/π), where R is the resistance of the right half of the body and Xc is the reactance measured at 50 kHz. The primary outcomes were the motor subscale of the functional independence measure (FIM) at discharge and FIM change between admission and discharge. Secondary outcomes included FIM scores for specific activities. Multiple linear regression analysis was performed to assess associations. Phase angles of the healthy upper and lower limbs demonstrated stronger associations with discharge FIM motor scores (β = 0.175 and β = 0.105, respectively) and FIM motor gain (β = 0.242 and β = 0.092, respectively) compared with whole body or paretic limb phase angles. Upper limb phase angles were more closely related to grooming and toileting abilities, whereas lower limb phase angles were associated with both toileting and locomotion at discharge. Segmental phase angles, particularly those of the nonparetic limbs, are promising predictors of functional outcomes in patients after stroke. Assessing segmental phase angles may guide targeted interventions and rehabilitation strategies for improving specific activities of daily living.

Association Between Racial Marginalization with Direct Healthcare Expenditure, Time at Home and Rehabilitation Access Following Moderate to Severe Traumatic Brain Injury.

To determine the association between residence in racialized neighborhoods with direct healthcare expenditure and days at home (DAH) after moderate to severe traumatic brain injury (TBI). Differences in ethno-racial background have been associated with health outcome disparities. Much of this prior research was conducted in settings without universal healthcare coverage. The influence of ethno-racial background on health outcomes after TBI in universal healthcare settings remains unclear. This retrospective multicenter cohort study utilized linked administrative health data to identify adults sustaining moderate to severe TBI between 2009-2021. The primary exposure was an area-level index corresponding to the degree of racialized and immigrant populations within neighborhoods of residence (Q1-least racialized; Q5-most racialized). Co-primary outcomes were direct healthcare expenditure and DAH365days after injury. Secondary outcomes included discharge to rehabilitation and functional independence measure (FIM) scores at rehabilitation discharge. 6,188 patients met inclusion criteria. Patients in the most racialized neighborhoods incurred higher crude and adjusted direct healthcare costs compared to those in the least racialized neighborhoods. This effect was driven predominantly by physician claims and acute care costs. There were no significant differences in crude or adjusted DAH across quintiles. Access to rehabilitation and discharge FIM scores were comparable for patients residing different racialized neighborhood quintiles. Despite differences in healthcare expenditure, this study found similar home time, access to rehab and discharge FIM scores for TBI patients according to racialized neighborhood residence. Recognizing the limitations of area-level indices, our findings suggest equitable care delivery in a publicly funded universal care environment.

Effects of structured positive feedback intervention on standing reach ability among older adults admitted to a convalescent rehabilitation ward: a small-sample pilot randomized controlled trial.

Interventions to improve the standing reach ability of older adults are essential for full functional independence, and structured positive feedback (PF) may be an effective intervention strategy. The purposes of this pilot randomized controlled trial (RCT) are to investigate the preliminary efficacy of structured PF for improving the standing reach ability of older patients admitted to a convalescent rehabilitation ward and evaluate the feasibility of a future full-scale RCT. Thirty-two eligible older adults (83.3 ± 5.9years, 23 women) out of 587 potential participants were randomly assigned 1:1 to structured PF (experimental) and conventional rehabilitation (control) groups. Only the experimental group received PF intervention for standing reach ability once every 3days. Both groups engaged in conventional rehabilitation programs for 2-3h every day. The primary outcome was change in Functional Reach Test (FRT) performance after 5weeks of the indicated intervention compared to baseline. Secondary outcomes were change in Short Falls Efficacy Scale International (Short FES-I), a self-reported measure of fear of falling, and Functional Independence Measure (FIM) scores after the 5-week intervention. The estimated difference in mean FRT change (∆) between experimental and control groups was -4.1cm (P = 0.07) according to a linear mixed model, supporting the potential efficacy of PF for improving standing reach ability. Further, Hedge's g value was 0.71, consistent with a moderate effect size. However, the estimated mean change in Short FES-I between groups also indicated greater fear of falling in the experimental group (∆ = -4.5, P = 0.009, g = 1.0). In contrast, the intervention effect on FIM was negligible (∆ = 2.0, P = 0.66, g = -0.1). These results support the preliminary effectiveness of structured PF for improving the standing reach ability of older adults. A larger-sample RCT is warranted for validation and optimization of the structured PF protocol. The University Hospital Medical Information Network (UMIN) Registered 31 May 2022 (UMIN000047647).

Assessment of Functioning and the Integration of Patients After Traumatic Brain Injury in Their Homes and Social Environments Following Inpatient Rehabilitation

Introduction: Patients with head injuries usually return to their home environments after completing rehabilitation, which is an additional challenge in the case of functional, motor or cognitive impairment. In order to identify the problems that such patients face and to objectify their problems with integration, we used the Community Integration Questionnaire-Revised (CIQ-R). At the same time, the validity of the translation of the questionnaire into Slovenian was checked. Methods: The CIQ-R was translated, and patients were telephoned twice, 14 days apart. In addition, they were assessed using the Functional Independence Measure (FIM) during the first call. The reliability of the CIQ-R in terms of internal consistency was assessed using Cronbach’s alpha and Guttman’s lambda-2. The reliability in terms of repeated measures was assessed using intraclass correlation (ICC). The association between FIM and CIQ-R scores was assessed using Pearson’s correlation. Results: Internal consistency of the CIQ-R was high (α = 0.8, λ = 0.85), and there was a very high re-test stability of the overall CIQ-R score (ICC = 0.95). The cognitive component of the FIM in the home environment was linearly associated with the CIQ-R score (r = 0.8, p ≤ 0.001). Conclusions: The translation of the CIQ-R questionnaire into Slovenian was successfully validated, and we proved its potential suitability for clinical use.

Using Existing Clinical Data to Measure Older Adult Inpatients' Frailty at Admission and Discharge: Hospital Patient Register Study.

Frailty is a widespread geriatric syndrome among older adults, including hospitalized older inpatients. Some countries use electronic frailty measurement tools to identify frailty at the primary care level, but this method has rarely been investigated during hospitalization in acute care hospitals. An electronic frailty measurement instrument based on population-based hospital electronic health records could effectively detect frailty, frailty-related problems, and complications as well be a clinical alert. Identifying frailty among older adults using existing patient health data would greatly aid the management and support of frailty identification and could provide a valuable public health instrument without additional costs. We aim to explore a data-driven frailty measurement instrument for older adult inpatients using data routinely collected at hospital admission and discharge. A retrospective electronic patient register study included inpatients aged ≥65 years admitted to and discharged from a public hospital between 2015 and 2017. A dataset of 53,690 hospitalizations was used to customize this data-driven frailty measurement instrument inspired by the Edmonton Frailty Scale developed by Rolfson et al. A 2-step hierarchical cluster procedure was applied to compute e-Frail-CH (Switzerland) scores at hospital admission and discharge. Prevalence, central tendency, comparative, and validation statistics were computed. Mean patient age at admission was 78.4 (SD 7.9) years, with more women admitted (28,018/53,690, 52.18%) than men (25,672/53,690, 47.81%). Our 2-step hierarchical clustering approach computed 46,743 inputs of hospital admissions and 47,361 for discharges. Clustering solutions scored from 0.5 to 0.8 on a scale from 0 to 1. Patients considered frail comprised 42.02% (n=19,643) of admissions and 48.23% (n=22,845) of discharges. Within e-Frail-CH's 0-12 range, a score ≥6 indicated frailty. We found a statistically significant mean e-Frail-CH score change between hospital admission (5.3, SD 2.6) and discharge (5.75, SD 2.7; P<.001). Sensitivity and specificity cut point values were 0.82 and 0.88, respectively. The area under the receiver operating characteristic curve was 0.85. Comparing the e-Frail-CH instrument to the existing Functional Independence Measure (FIM) instrument, FIM scores indicating severe dependence equated to e-Frail-CH scores of ≥9, with a sensitivity and specificity of 0.97 and 0.88, respectively. The area under the receiver operating characteristic curve was 0.92. There was a strong negative association between e-Frail-CH scores at hospital discharge and FIM scores (rs=-0.844; P<.001). An electronic frailty measurement instrument was constructed and validated using patient data routinely collected during hospitalization, especially at admission and discharge. The mean e-Frail-CH score was higher at discharge than at admission. The routine calculation of e-Frail-CH scores during hospitalization could provide very useful clinical alerts on the health trajectories of older adults and help select interventions for preventing or mitigating frailty.

Actual situation of nutritional management and factors related to activities of daily living ability at discharge in convalescent rehabilitation ward.

In this study, we aimed to investigate changes in the Geriatric Nutritional Risk Index (GNRI), a nutrition-related prognostic indicator, in our convalescent rehabilitation ward and determine how this index relates to activities of daily living (ADL) ability at discharge. We retrospectively analyzed data of 107 patients admitted to our convalescent rehabilitation ward between April and September 2023. We used the GNRI as the nutritional risk index and Functional Independence Measure (FIM) as the ADL index. The patients' mean age was 80.0 ± 10.3 years; 38 were males and 69 females. The patients' mean body weight at admission was 51.2 ± 10.2 kg, which significantly decreased to 50.2 ± 9.4 kg at discharge (p = 0.0006). Their mean body mass index (BMI) also significantly decreased from 21.4 ± 3.4 at admission to 20.0 ± 8.2 at discharge (p = 0.002). The mean GNRI significantly decreased from 93.1 ± 8.6 at admission to 91.7 ± 8.4 at discharge (p = 0.023). The mean body weight decreased until the fourth month after admission; however, no decreasing trend after the fifth month was observed. The mean monthly energy intake gradually increased after admission and reached the calculated energy requirement of 1,415 ± 22 kcal at the fifth month. Multivariate analysis demonstrated that at discharge, the GNRI score was positively associated with the FIM score (β = 0.21, p = 0.0008). Body weight and GNRI scores decreased after admission but stopped decreasing after the fifth month due to a gradual increase in energy intake. At discharge, the FIM score was positively associated with the GNRI score. We expected that active nutritional therapy from the beginning of hospitalization would increase the GNRI by the time of discharge and eventually improve ADL ability at discharge.

The Significance of an Initial Controlling Nutritional Status Score in Predicting the Functional Outcome, Complications, and Mortality in a First-Ever Ischemic Stroke

Background and Purpose: Nutritional status can influence the outcomes and mortality of various diseases. The association between initial nutritional status and ischemic stroke outcomes, however, remains poorly understood. This study investigated whether the Controlling Nutritional Status (CONUT) score at admission could predict functional recovery, complications, and survival following an ischemic stroke. Methods: We enrolled a total of 938 patients experiencing their first acute ischemic stroke and categorized them into three groups based on their CONUT score at admission: CONUT 0–1, CONUT 2–4, and CONUT 5–12. The CONUT score was assessed using the serum albumin, total cholesterol, and lymphocyte count. We evaluated the incidence of complications during their hospital stay. Outcomes, including the Modified Rankin Scale (mRS), Functional Independence Measurement (FIM), Functional Ambulatory Classification (FAC), and mortality, were assessed at baseline, as well as at three and six months post-stroke. Results: CONUT scores were significantly associated with functional outcomes (mRS, FIM, and FAC) and mortality during the six-month follow-up period post-stroke (all p &lt; 0.05). The CONUT 5–12 group exhibited significantly poorer improvements in mRS, FIM, and FAC scores (all p &lt; 0.05) and a lower survival rate (p &lt; 0.01) during the six-month follow-up compared to the CONUT 0–1 and CONUT 2–4 groups. Additionally, the incidence of pneumonia, urinary tract infections, pressure sores, falling injuries, and fractures was significantly higher in the CONUT 5–12 group than in the other groups (all p &lt; 0.01). Conclusions: CONUT scores at admission are associated with functional recovery, mortality, and the incidence of complications following a first-ever ischemic stroke. Consequently, the early identification of patients at risk of malnutrition via CONUT scores can be crucial in enhancing patient assessment after an acute stroke.

Activities of daily living limitation and functional decline during hospitalization predict 180-day readmission and mortality in older patients with pneumonia: A single-center, retrospective cohort study

BackgroundThe role of activities of daily living (ADL) as a predictor of adverse outcomes in patients with pneumonia is unclear. This study aimed to assess the association between ADL, including physical and cognitive function, and death or readmission in older inpatients with pneumonia. MethodsThis retrospective, single-center, observational study included consecutive older inpatients with pneumonia between October 2018 and December 2019. ADL was assessed using the Functional Independence Measure (FIM). Functional decline during hospitalization was defined as a decrease of at least 1 point in FIM at discharge from admission. The primary outcome was the time to composite 180-day mortality and readmission from any cause after discharge. ResultsIn total, 363 patients (median [interquartile range] age: 80 [73–86] years, male: 68 %) were divided according to the median FIM scores (≥100, n = 183 and < 100, n = 180). Among the patients, 25 experienced functional decline during hospitalization, 69 were readmitted, and 17 died. In the Kaplan–Meier analysis, both the lower FIM group and the functional decline group had significantly lower event-free rates than the higher FIM groups and the non-functional decline groups (log-rank test, p < 0.001), respectively. After multivariate analysis, both the lower FIM (adjusted HR, 2.11; 95 % CI, 1.24–3.58; p = 0.006) and functional decline (adjusted HR, 3.18; 95 % CI, 1.44–7.05; p = 0.005) were significantly associated with the primary outcome. ConclusionsIn older patients hospitalized with pneumonia, ADL limitations at discharge and a decline in ADL were associated with poor outcomes.

Analysis of the recovery process and activities of daily living independence in pusher behavior and unilateral spatial neglect

ObjectiveTo investigate the recovery processes of pusher behavior (PB) and unilateral spatial neglect (USN) based on the severity of PB and USN, to determine the relationship between activities of daily living (ADL) independence levels. DesignThis retrospective study aimed to examine the temporal changes and their association with ADL independence levels based on the severity of PB and USN. SettingRecovery ward of Moriyama Neurological Center Hospital between March 2017 and October 2022. ParticipantsWe included all patients with cerebrovascular disease admitted to the recovery ward of Moriyama Neurological Center Hospital between March 2017 and October 2022. A total of 174 patients with PB and USN were classified into four groups as follows; severe PB and severe USN (Group A), severe PB and mild USN (Group B), mild PB and severe USN (Group C), and mild PB and mild USN (Group D). InterventionsNot applicable. Main Outcome MeasuresKaplan–Meier survival analysis was used to determine whether the time to recovery from PB or USN (SCP: ≤1.75 points; CBS: 0 points) differed between groups. Additionally, group differences in Functional Independence Measure (FIM) scores and efficiencies were examined. ResultsThere were significant differences among Groups A and B and Groups A and C, as determined by the log-rank test (P<0.05), and recovery was prolonged when both PB and USN were severely impaired. Similarly, FIM scores and efficiencies were lower in Group A (P<0.05). When PB and USN were severely impaired, ADL was adversely affected, and the recovery process was prolonged. In addition, when one of the two symptoms was severe and the other was mild, each recovery course tended to show improvement, suggesting that they exerted a mutual influence on each other. ConclusionsThese findings indicate that severity classification may help to determine functional prognosis in patients with PB and USN.

How Are FIM Gains Improved after Intensive Rehabilitation for Cerebrovascular Diseases?

The purpose of this study was to determine functional independence measure (FIM) gains based on clinical factors after rehabilitation for cerebrovascular diseases, and to determine how FIM scores and FIM gains can predict rehabilitation outcomes. Of the 181 patients in the study 161 suffered strokes (cerebral infarction 107, cerebral hemorrhage 41, subarachnoid hemorrhage 12, subdural hematoma 1). There were also 12 traumatic brain injuries, and 8 other miscellaneous cases. Dementia, higher brain dysfunction, etiology, sex, age, history of cerebrovascular diseases, location involvement, disability severity, duration of hospitalization and period from onset to rehabilitation were analyzed using FIM. FIM gains decreased in relation to an increase in age. Patients with intermediate disability (FIM 41-80) on admission showed significantly higher FIM-total gain on discharge than others. Factors influencing FIM gain were revealed to be age, duration of hospitalization, FIM gain 4 weeks after admission, etiology, disability severity, dementia and past history of cerebrovascular diseases. Multiple regression analysis determined that significant factors to contribute FIM gain were duration of hospitalization, FIM gain at 4 weeks after admission, age, and disability severity. FIM scores and FIM gains could predict rehabilitation outcomes.

Early screening for post-stroke depression and its effect on functional outcomes, quality of life, and mortality: A meta-analysis

BACKGROUND Post-stroke depression (PSD) is a common and debilitating condition affecting stroke survivors, significantly impacting their recovery and overall quality of life. AIM To assess the effects of early PSD screening on functional outcomes, quality of life, and mortality. METHODS From an initial pool of 1065 articles, 6 studies met the inclusion criteria and were selected for analysis. Functional outcomes were measured using the functional independence measure (FIM). RESULTS The analysis revealed a significant improvement in FIM scores for a PSD screening group compared to controls [standardized mean difference (SMD) = 8.90, 95% confidence interval (CI): 4.65-13.15, P &lt; 0.01]. Quality of life was assessed using the Stroke-Specific Quality of Life Scale, with the screening group showing significantly higher scores (SMD = 20.83, 95%CI: 15.27-26.38, P &lt; 0.01). Mortality analysis indicated a reduction in five-year mortality rates for the PSD screening group. CONCLUSION Early PSD screening enhances functional recovery, improves quality of life, and reduces mortality rates in stroke survivors. Thus, integrating PSD screening into routine stroke care improves long-term outcomes for patients.

Social participation and its relationships with sensorimotor and functional aspects in post-stroke patients

Objective: To describe social participation and assess its correlation with sensorimotor impairment and functional independence in patients after a stroke in a region of Northeast Brazil. Methods: A cross-sectional study was conducted with 34 stroke patients, aged 18 years or older, selected for convenience from the institution's health records. Participants were assessed using the following clinical instruments: Assessment of Life Habits 3.1 (LIFE-H 3.1), Functional Independence Measure (FIM), Fugl-Meyer Assessment (FMA) - motor subsection (upper limb-UL and lower limb-LL), and Nottingham Sensory Assessment (NSA). Results: Post-stroke patients exhibited reduced social participation (LIFE-H 3.1), with moderate positive correlations observed between the personal, mobility, and responsibility domains and the total scores of FIM, FIM motor, FMA-motor, and FMA-UL. There was a moderate positive correlation between the total scores of LIFE-H 3.1, FIM, FMA-motor, and FMA-UL. Conclusion: The present study demonstrated a critical loss of social participation in post-stroke subjects, likely attributed to various sensorimotor and functional aspects, in a semi-arid region of Northeast Brazil.

Improvements in activities of daily living among patients with brain tumors are associated with age, baseline physical function, duration of rehabilitation, and tumor recurrence but not type.

Genetic testing has improved the accuracy of diagnosis of brain tumors, and treatment is now tailored to the type of brain tumor. In contrast, the factors that influence the improvement in independence in activities of daily living (ADLs) following rehabilitation have not been clarified, particularly the role of tumor type. In this retrospective cohort study of 358 participants, we analyzed changes in the Functional Independence Measure (FIM) from pre-rehabilitation to post-rehabilitation provided in an acute care hospital. Multiple regression was used to determine whether FIM gain is associated with age, gender, preadmission Karnofsky Performance Status (KPS), number of rehabilitation days, average duration of daily therapy (min/day), and tumor recurrence and type (WHO grade 1, 2, 3, and 4 gliomas; primary central nervous system lymphomas; and metastatic brain tumors). The results showed that older age (β -0.183), tumor recurrence (β -0.137), preadmission KPS < 80 (β -0.180), and higher baseline total FIM score (β -0.470) were associated with lower FIM gain whereas the average duration of daily therapy (β 0.153) was associated with higher FIM gain. Brain tumor type was not associated with FIM gain. Improved independence in ADLs is more influenced by demographic, functional status, and treatment factors than differences in brain tumor type.

Improved trunk muscle quality in patients with stroke increases improvements in activities of daily living

BackgroundThis study aimed to determine whether an increased trunk muscle quality index (TMQI) is associated with activities of daily living (ADL) in patients ≥ 65 years of age with cerebral infarction in a convalescent rehabilitation ward. MethodsThis retrospective observational study included patients aged ≥ 65 years who were admitted for post-stroke rehabilitation in Okinawa, Japan, between May 2018 and December 2022. The TMQI was calculated at admission and discharge using bioelectrical impedance analysis. Patients were divided into two groups based on the change in the TMQI during hospitalization: increase-in-TMQI and no-increase-in-TMQI groups. Multiple regression analysis was employed to explore the impact of increased TMQI on functional independence measure (FIM) -motor gain. ResultsWe included a total of 315 patients (79.1 ± 7.9 years of age, 51.7% men) in our analyses. Over half (165 [52.4%]) of the patients exhibited an increase in TMQI scores, and 150 (47.6%) patients did not exhibit an increase. No significant difference was observed in motor FIM score and motor FIM gain at admission and discharge between the groups with and without increased TMQI. Increased TMQI was independently associated with increased FIM-motor gain (adjusted R2 = 0.340 and R2 = 0.357, coefficient = 1.736, 95% confidence interval: 0.52–2.95, P = 0.005). ConclusionsThe results of this study suggest that increased TMQI has a positive effect on the recovery of physical function in patients with stroke. Further prospective studies are needed to elucidate the relationship between increased TMQI and ADL.

Efficacy of Motor Imagery in the Rehabilitation of Stroke Patients: A Scope Review

This review examines the efficacy of motor imagery (MI) as a supplementary rehabilitation technique for stroke patients. Nine randomized controlled trials (RCTs) were analyzed, highlighting MI's potential to enhance motor recovery, mobility, balance, and psychological well-being. Significant improvements in upper-limb function were observed with combined mental and physical practice, evidenced by notable gains in Fugl-Meyer Assessment (FMA) and Action Research Arm Test (ARAT) scores. MI-based exercise programs improved mobility and balance in elderly patients, reducing fall risk as measured by the Timed Up and Go (TUG) test and Berg Balance Scale (BBS). MI was also found to enhance self-efficacy and functional performance, with significant increases in Functional Independence Measure (FIM) and General Self-Efficacy Scale (GSES) scores. Neuroimaging studies revealed that MI activates cortical areas associated with motor control, supporting its role in promoting neural plasticity. Despite these promising results, the heterogeneity in participant characteristics, stroke severity, and MI protocols across studies poses challenges to standardization. Additionally, small sample sizes and reliance on self-report measures limit the generalizability of findings. Nevertheless, MI's low cost, minimal risk, and ease of integration into existing rehabilitation protocols make it a valuable adjunct to physical therapy. Standardized guidelines and personalized MI exercises tailored to individual needs are essential for maximizing benefits. Integrating MI into clinical practice can significantly enhance both physical and psychological recovery outcomes for stroke patients, offering a comprehensive approach to rehabilitation.

Data-driven prediction of spinal cord injury recovery: An exploration of current status and future perspectives

Spinal Cord Injury (SCI) presents a significant challenge in rehabilitation medicine, with recovery outcomes varying widely among individuals. Machine learning (ML) is a promising approach to enhance the prediction of recovery trajectories, but its integration into clinical practice requires a thorough understanding of its efficacy and applicability. We systematically reviewed the current literature on data-driven models of SCI recovery prediction. The included studies were evaluated based on a range of criteria assessing the approach, implementation, input data preferences, and the clinical outcomes aimed to forecast. We observe a tendency to utilize routinely acquired data, such as International Standards for Neurological Classification of SCI (ISNCSCI), imaging, and demographics, for the prediction of functional outcomes derived from the Spinal Cord Independence Measure (SCIM) III and Functional Independence Measure (FIM) scores with a focus on motor ability. Although there has been an increasing interest in data-driven studies over time, traditional machine learning architectures, such as linear regression and tree-based approaches, remained the overwhelmingly popular choices for implementation. This implies ample opportunities for exploring architectures addressing the challenges of predicting SCI recovery, including techniques for learning from limited longitudinal data, improving generalizability, and enhancing reproducibility. We conclude with a perspective, highlighting possible future directions for data-driven SCI recovery prediction and drawing parallels to other application fields in terms of diverse data types (imaging, tabular, sequential, multimodal), data challenges (limited, missing, longitudinal data), and algorithmic needs (causal inference, robustness).

Prognostic Equations and Accuracy of a Total Score of Functional Independence Measure at Discharge for Different Diseases in a Convalescent Rehabilitation Ward.

Prognosisand goal setting from admission in the convalescent rehabilitation ward, supported by a multidisciplinary team, enhance rehabilitation and discharge support. Predicting functional independence measure (FIM) outcomes can further optimize these processes. This study aimed to develop prognostic equations for the motor FIMat discharge for stroke, hip fracture (HF), vertebral compression fractures (VCFs), and total knee arthroplasty (TKA), which are common diseases in patients admitted to convalescent rehabilitation wards, using multiple regression analysis, and to clarify the difference in the accuracy of the predicted motor FIM according to the disease. This study included 965 patients admitted to our hospital. The objective variable consists of the motor FIM at discharge, and the explanatory variables were age, sex, days from onset to admission, total admission motor FIM, and total admission cognitive FIM. A stepwise multiple regression analysis was performed. The analysis of the difference in the accuracy of predicted motor FIM by disease used the absolute value of the residuals. The total motor FIM and cognitive FIM at admission were extracted for all four diseases included in this study. The absolute value of the residuals appeared to be more accurate for TKA, HF, stroke, and VCF in that order. Although differences in the accuracy of the prediction equation were observed by disease, this prediction equation can be used as an approach to review the details of rehabilitation and discharge and can be tailored to each case.

Transition from rehabilitation hospital to the National Disability Insurance Scheme (NDIS) for people with brain injury and spinal cord injury: a data linkage protocol

Early Postoperative Functional Recovery in Older Patients With Periprosthetic Femoral Fractures: Comparison Between Cemented and Cementless Stem Revisions

BackgroundEarly postoperative functional recovery is important in older patients with lower-extremity fractures to prevent disuse, and periprosthetic femoral fractures (PFFs) are no exception. This study aimed to compare the postoperative functional recovery in the early phase after revision for PFF with loose stems between cemented and cementless stems. MethodsEighteen patients with Unified Classification System type B2 PFF were included in this retrospective cohort study with a follow-up period of about 2 years. All patients underwent stem revision and were divided into 2 groups: the cemented stem group (n = 9) and the cementless stem group (n = 9). In postrevision, functional independence measure score, independent walk rate, activities of daily living recovery rate to the original level at 2 weeks postoperatively, the Beals and Tower classification for radiological status, and survival rate for readmission as endpoints were compared between the 2 groups. ResultsPatients in the cemented group recovered functional mobility earlier than in the cementless group, with higher postoperative functional independence measure functional subscale values (73 vs 50 points, P = .02), higher independent walk rate (89 vs 11%, P < .01), and more postoperative activities of daily living recovery (100% vs 44%, P = .03) at 2 weeks postoperatively. The Beals and Tower classification and survival rates were similar in both groups. ConclusionsRevision using a cemented stem for PFF in older patients was a useful surgical procedure in terms of early postoperative functional recovery. Cemented stem revision was comparable with cementless in bone union and safety at 2 years postoperatively.
