Cost-effectiveness analysis of overground robotic training versus conventional locomotor training in people with spinal cord injury.

BACKGROUND: Few, if any estimates of cost-effectiveness for locomotor training strategies following spinal cord injury (SCI) are available. The purpose of this study was to estimate the cost-effectiveness of locomotor training strategies following spinal cord injury (overground robotic locomotor training versus conventional locomotor training) by injury status (complete versus incomplete) using a practice-based cohort. METHODS: A probabilistic cost-effectiveness analysis was conducted using a prospective, practice-based cohort from four participating Spinal Cord Injury Model System sites. Conventional locomotor training strategies (conventional training) were compared to overground robotic locomotor training (overground robotic training). Conventional locomotor training included treadmill-based training with body weight support, overground training, and stationary robotic systems. The outcome measures included the calculation of quality adjusted life years (QALYs) using the EQ-5D and therapy costs. We estimate cost-effectiveness using the incremental cost utility ratio and present results on the cost-effectiveness plane and on cost-effectiveness acceptability curves. RESULTS: Participants in the prospective, practice-based cohort with complete EQ-5D data (n = 99) qualified for the analysis. Both conventional training and overground robotic training experienced an improvement in QALYs. Only people with incomplete SCI improved with conventional locomotor training, 0.045 (SD 0.28), and only people with complete SCI improved with overground robotic training, 0.097 (SD 0.20). Costs were lower for conventional training, $1758 (SD $1697) versus overground robotic training $3952 (SD $3989), and lower for those with incomplete versus complete injury. Conventional overground training was more effective and cost less than robotic therapy for people with incomplete SCI. Overground robotic training was more effective and cost more than conventional training for people with complete SCI. The incremental cost utility ratio for overground robotic training for people with complete spinal cord injury was $12,353/QALY. CONCLUSIONS: The most cost-effective locomotor training strategy for people with SCI differed based on injury completeness. Conventional training was more cost-effective than overground robotic training for people with incomplete SCI. Overground robotic training was more cost-effective than conventional training for people with complete SCI. The effect estimates may be subject to limitations associated with small sample sizes and practice-based evidence methodology. These estimates provide a baseline for future research.

Feasibility, Acceptability, and Efficacy of Mindfulness Training in People With Upper Motor Neuron Disorders: A Systematic Review.

OBJECTIVES: This systematic review aims to gain a comprehensive understanding of the feasibility, acceptability, and efficacy of mindfulness-based interventions (MBIs) on depression, anxiety, fatigue, and health-related quality of life among individuals with upper motor neuron disorders (UMNDs). DATA SOURCES: PubMed, PsycINFO, Excerpta Medica Database, and Cumulative Index to Nursing and Allied Health Literature were searched for relevant studies published between January 2001 and June 2021. STUDY SELECTION: Clinical trials published in English evaluating MBIs in adults with the 4 most common UMNDs (multiple sclerosis, brain injury including stroke, spinal cord injury, amyotrophic lateral sclerosis) were included. DATA EXTRACTION: Two reviewers independently performed the risk of bias assessment using standardized tools and extracted desired data electronically. DATA SYNTHESIS: A total of 44 studies were included: 26 randomized controlled trials, 10 nonrandomized controlled trials, and 8 pre-post intervention studies. The average ± SD duration of MBIs was 8±2 weeks. On average, 85%±14% of participants completed the MBI, and the retention rate at follow-up was 80%±16%. Only 14% of the studies delivered MBIs virtually, and feasibility metrics were similar to in-person studies. Among studies reporting acceptability data, most participants reported satisfaction with the MBI. Randomized controlled trials that evaluated the effects of MBI on depression, anxiety, fatigue, and quality of life revealed greater relative improvement in these outcomes among MBI participants compared with controls, with differences greater when compared with passive control than active control participants. None of the studies included in this review studied dose response. CONCLUSIONS: Based on current data, MBIs are feasible and offer a promising approach to address the biopsychosocial needs of individuals with UMNDs. MBIs are associated with a high acceptance rate among participants, with notable improvements in depression, anxiety, fatigue, and quality of life post intervention. Future studies are needed to evaluate alternate models of delivery of MBIs and the dose-response relationship.

Prevalence and Impact of Neuropathic and Nonneuropathic Pain in Chronic Spinal Cord Injury.

OBJECTIVE: To compare prevalence, intensity ratings, and interference ratings of neuropathic pain (NeuP) and nociceptive pain in people with chronic spinal cord injury (SCI) DESIGN: Cross-sectional survey. SETTING: Six SCI Model System centers in the United States. PARTICIPANTS: Convenience sample of 391 individuals (N=391) with traumatic SCI, 18 years or older, 81% male, 57% White. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Survey based on the International Spinal Cord Injury Pain Basic Data Set and the Spinal Cord Injury Pain Instrument, including 0-10 numeric ratings of pain intensity and pain interference with daily activities, mood, and sleep RESULTS: A total of 80% of those surveyed reported having at least 1 pain problem; 58% reported 2 or more pain problems; 56% had probable NeuP; and 49% had non-NeuP. When comparing ratings for all pains (n=354 for NeuP, n=290 for non-NeuP) across participants, probable NeuPs were significantly more intense (6.9 vs 5.7) and interfered more with activities (5.2 vs 3.7), mood (4.9 vs 3.2), and sleep (5.4 vs 3.6) than non-NeuPs (all P<.001). However, when comparing ratings for probable NeuPs and non-NeuPs within participants, for the subgroup of 94 participants with both pain types, only ratings for sleep interference were found to be significantly different between the pain types. Additionally, we found significantly greater prevalence of NeuP and non-NeuP for women compared with men and of NeuP for those with paraplegia compared with those with tetraplegia. CONCLUSIONS: Independent assessment of the pain conditions experienced by an individual with SCI is useful in understanding the differential effect that pain type has on quality of life. This is particularly important regarding sleep interference and should be kept in mind when determining treatment strategies for meeting patient-centered outcome goals.

Predicting Duration of Outpatient Physical Therapy Episodes for Individuals with Spinal Cord Injury Based on Locomotor Training Strategy.

OBJECTIVE: To characterize individuals with spinal cord injuries (SCI) who use outpatient physical therapy or community wellness services for locomotor training and predict the duration of services, controlling for demographic, injury, quality of life, and service and financial characteristics. We explore how the duration of services is related to locomotor strategy. DESIGN: Observational study of participants at 4 SCI Model Systems centers with survival. Weibull regression model to predict the duration of services. SETTING: Rehabilitation and community wellness facilities at 4 SCI Model Systems centers. PARTICIPANTS: Eligibility criteria were SCI or dysfunction resulting in motor impairment and the use of physical therapy or community wellness programs for locomotor/gait training. We excluded those who did not complete training or who experienced a disruption in training greater than 45 days. Our sample included 62 participants in conventional therapy and 37 participants in robotic exoskeleton training. INTERVENTIONS: Outpatient physical therapy or community wellness services for locomotor/gait training. MAIN OUTCOME MEASURES: SCI characteristics (level and completeness of injury) and the duration of services from medical records. Self-reported perceptions of SCI consequences using the SCI-Functional Index for basic mobility and SCI-Quality of Life measurement system for bowel difficulties, bladder difficulties, and pain interference. RESULTS: After controlling for predictors, the duration of services for the conventional therapy group was an average of 63% longer than for the robotic exoskeleton group, however each visit was 50% shorter in total time. Men had an 11% longer duration of services than women had. Participants with complete injuries had a duration of services that was approximately 1.72 times longer than participants with incomplete injuries. Perceived improvement was larger in the conventional group. CONCLUSIONS: Locomotor/gait training strategies are distinctive for individuals with SCI using a robotic exoskeleton in a community wellness facility as episodes are shorter but individual sessions are longer. Participants' preferences and the ability to pay for ongoing services may be critical factors associated with the duration of outpatient services.

Utilization of Complementary and Integrative Health Care by People With Spinal Cord Injury in the Spinal Cord Injury Model Systems: A Descriptive Study.

OBJECTIVE: To characterize the use of complementary and integrative health care (CIH) by people with spinal cord injury. DESIGN: Cross-sectional self-report study. SETTING: Participants were recruited from 5 Spinal Cord Injury Model Systems (SCIMS) centers across the United States. INTERVENTIONS: Not applicable. PARTICIPANTS: A total of 411 persons enrolled in the SCIMS completing their SCIMS follow-up interview between January 2017 and July 2019 (N = 411). MAIN OUTCOME MEASURES: Participants completed a survey developed for this study that included questions about types of CIH currently and previously used, reasons for current and previous use, reasons for discontinuing use of CIH, and reasons for never using CIH since injury. RESULTS: Of the 411 respondents, 80.3% were current or previous users of CIH; 19.7% had not used CIH since injury. The most commonly used current types of CIH were multivitamins (40.0%) and massage (32.6%), whereas the most common previously used type of CIH was acupuncture (33.9%). General health and wellness (61.4%) and pain (31.2%) were the most common reasons for using CIH. The primary reason for discontinuing CIH was that it was not helpful (42.1%). The primary reason for not using CIH since injury was not knowing what options are available (40.7%). CONCLUSIONS: These results point to the importance for rehabilitation clinicians to be aware that their patients may be using 1 or more CIH approaches. Providers should be open to starting a dialogue to ensure the health and safety of their patients because there is limited information on safety and efficacy of CIH approaches in this population. These results also set the stage for further analysis of this data set to increase our knowledge in this area.

Adolescents' Frequency of Alcohol Use and Problems from Alcohol Abuse: Integrating Dating Partners with Parent and Peer Influences.

Despite the centrality of dating relationships for teens, it is unclear whether the influence of romantic partners' alcohol use on adolescents' under-age drinking is distinct from the influence of peers and parents. To address this gap, this study used longitudinal data from a population-based sample of 825 adolescents (49% male, 51% female), ages 12 to 19. Adolescents completed a survey using laptops for privacy, and a parent completed a survey separately. Ordinary least squares and logistic regression models assessed alcohol use frequency and alcohol problems and included dating partners' drinking, adolescents' prior drinking, peers' drinking, parents' substance use, parental monitoring, and sociodemographic background characteristics. Alcohol use frequency and alcohol problems were influenced by dating partners' alcohol use and dating partners' influence was stronger on older adolescents and male adolescents. The study results are useful for public health messaging and prevention efforts by demonstrating the influence of parents, peers, and dating partners on teens' alcohol use.

Work-life balance among health administration faculty before and during the COVID-19 pandemic.

This current study examines measures of work-life balance among health administration faculty prior to and during the COVID-19 pandemic. A repeated cross-sectional design is used to analyze data collected from a national survey in 2018 and 2021. Changes in six different outcome measures of work-life balance were examined using multivariable logistic regression, controlling for health administration faculty characteristics. Compared to 2018 respondents, faculty respondents in 2021 were more likely to report that family and personal matters were interfering with their ability to do their job (OR = 1.93, p=0.001). Females more frequently reported that their career had suffered because of personal issues/obligations (OR = 1.82, p=0.003) but were less likely to report having enough time to get their teaching (OR = 0.68, p=0.026). Respondents with children 18 years or younger reported higher rates of regularly having to miss a meeting or event at home (OR = 1.88, p<0.001) and an event at work (OR = 3.74, p<0.001). These faculty also more frequently reported that family or personal matters were interfering with their ability to do their job (OR = 3.04, p<0.001) and that their career suffered because of personal issues/obligations (OR = 2.09, p=0.001). Given the implications of work-life conflicts to organizational outcomes, academic leaders and university decision-makers should consider adopting strategies to mitigate the effects of these disruptions to the work-life equilibrium of academics.

Faculty salaries in health administration: trends and correlates 2015-2021.

In this study, we provide updated information on salaries of academic health administration (HA) faculty members based on data collected in 2015, 2018, and 2021 and examine characteristics associated with earnings. We present mean inflation-adjusted salaries by demographic characteristics, education, experience, productivity, and job activities. We find that salaries of assistant, associate, and full professors have kept up with inflation and there have not been significant changes in salary by any characteristics over time. As in previous iterations of similar survey data, there remain differences in salary by both gender and race. Higher salaries were associated with having a 12-month contract, being tenured or tenure-track, having an administrative position, and being in a department whose focus is not primarily teaching. Findings from our study will be of interest to individuals on the HA job market, hiring committees, and doctoral students preparing for a position after graduation.

Student perceptions of a teaching electronic medical record in Health Administration education.

Given the ubiquity of electronic health records (EHR), health administrators should be formally trained on the use and evaluation of EHR data for common operational tasks and managerial decision-making. A teaching electronic medical record (tEMR) is a fully operational electronic medical record that uses de-identified electronic patient data and provides a framework for students to familiarize themselves with the data, features, and functionality of an EHR. Although purported to be of value in health administration programs, specific benefits of using a tEMR in health administration education is unknown. We sought to examine Master of Health Administration (MHA) students' perceptions of the use, challenges, and benefits of a tEMR. We analyzed qualitative data collected from a focus group session with students who were exposed to the tEMR during a semester MHA course. We also administered pre- and post-survey questions on students' self-efficacy and perceptions of the ease of use, usefulness, and intention to use health care data analysis in their future jobs. We found several MHA students valued their exposure to the tEMR, as this provided them a realistic environment to explore de-identified patient data. Scores for students' perceived ease of using healthcare data analysis in their future job significantly increased following use of the tEMR (pre-test score M=3.31, SD=0.21; post-test score M=3.71, SD=0.18; p=0.01). Student exposure and use of a tEMR may positively affect perceptions of using EHR data for strategic and managerial tasks typical of health administrators.

Pubertal transition with current life stress and support alters longitudinal diurnal cortisol patterns in adolescents exposed to early life adversity.

Current and early life stress (ELS) are associated with diurnal cortisol patterns, which themselves are associated with mental and physical health. The pubertal recalibration hypothesis suggests that the social environment can impact dysregulated cortisol patterns for previously ELS-exposed youth as they transition through puberty. This study examined longitudinal change in cortisol awakening response (CAR) and diurnal slope (DS) across puberty as a function of ELS in infancy, current stress, and social support (N = 290, 7-17 years). The CAR and DS were examined thrice annually with an accelerated longitudinal design with nurse-assessed puberty to assess associations between diurnal cortisol and pubertal recalibration with ELS and the current social environment. Exposure to ELS was associated with less steep DS but not changes in CAR, and no evidence of pubertal calibration was found. The DS became less steep for youth in later pubertal stages and as youth progressed through puberty. The CAR was steeper for youth in later pubertal stages. Across the cohort, current life stress and support were associated with changes in the DS and the CAR through the pubertal transition. The pubertal stage and the peripubertal and pubertal social environment may have important implications for adrenocortical functioning with or without exposure to ELS.

Core Competency Gaps Among Governmental Public Health Employees With and Without a Formal Public Health Degree.

OBJECTIVES: To examine the role of a formal public health degree as it relates to core competency needs among governmental public health employees. DESIGN: This cross-sectional study utilizes the 2017 Public Health Workforce Interests and Needs Survey (PH WINS). Bivariate relationships were analyzed by conducting χ tests of respondents' supervisory level and reported skill gaps. Multivariate logistic regressions of reported skill gaps were performed holding gender, age, race/ethnicity, highest degree attained, current employer, role type, tenure in current agency, and public health certificate attainment constant. SETTING: Nationally representative sample of government public health employees. PARTICIPANTS: A total of 30 276 governmental public health employees. MAIN OUTCOME MEASURE: Self-reported competency skills gaps. RESULTS: Among nonsupervisors, those with a public health degree had significantly lower odds of reporting a competency gap for 8 of the 21 skills assessed. Among supervisors/managers, those who had a formal public health degree had significantly lower odds of reporting a competency gap in 3 of the 22 skills assessed. Having a degree in public health was not significantly related to an executive's likelihood of reporting a skill gap across any of the 22 skills assessed. Regardless of supervisory level, having a public health degree was not associated with a reduced likelihood of reporting skill gaps in effective communication, budgeting and financial management, or change management competency domains. CONCLUSIONS: Possessing a formal public health degree appears to have greater value for skills required at the nonsupervisor and supervisor/manager levels than for skills needed at the executive level. Future work should focus on longitudinal evaluations of skill gaps reported among the public health workforce as changes in public health curricula may shift over time in response to newly revised accreditation standards. In addition, public health education should increase emphasis on communication, budgeting, systems thinking, and other management skills among their graduates.

Processing small sputum samples: a method validation study.

Background: Eosinophilia is frequently a feature of asthma. Sputum analysis can help with the diagnosis and phenotyping of asthma. The current gold standard method is unsuitable for samples <100 mg. However, children frequently produce samples below this threshold.Aim: To compare and validate our modified, small sample (>10 mg and <100 mg) sputum processing method (which omits sample filtering), with the current gold standard. Method: Prospective study of 32 adults with severe asthma providing sputum samples of sufficient size for dual processing. Results: The median (IQR) sample weight was 211.0 (162.4-185.5) mg and 57.5 (22.0-61.6) mg for standard, and small sputum sample processing respectively. There was no statistically significant difference in the median (IQR) cell counts between Method A and B, respectively: eosinophils 3.8% (1.5-14.0) versus 4.9% (1.3-15.5); neutrophils 78.1% (46.5-92.4) versus 65.0% (48.3-86.6). Conclusion: The small sputum sample processing is feasible and reliable, and yields similar results to standard processing.

Budget impact analysis of robotic exoskeleton use for locomotor training following spinal cord injury in four SCI Model Systems.

BACKGROUND: We know little about the budget impact of integrating robotic exoskeleton over-ground training into therapy services for locomotor training. The purpose of this study was to estimate the budget impact of adding robotic exoskeleton over-ground training to existing locomotor training strategies in the rehabilitation of people with spinal cord injury. METHODS: A Budget Impact Analysis (BIA) was conducted using data provided by four Spinal Cord Injury (SCI) Model Systems rehabilitation hospitals. Hospitals provided estimates of therapy utilization and costs about people with spinal cord injury who participated in locomotor training in the calendar year 2017. Interventions were standard of care walking training including body-weight supported treadmill training, overground training, stationary robotic systems (i.e., treadmill-based robotic gait orthoses), and overground robotic exoskeleton training. The main outcome measures included device costs, training costs for personnel to use the device, human capital costs of locomotor training, device demand, and the number of training sessions per person with SCI. RESULTS: Robotic exoskeletons for over-ground training decreased hospital costs associated with delivering locomotor training in the base case analysis. This analysis assumed no difference in intervention effectiveness across locomotor training strategies. Providing robotic exoskeleton overground training for 10% of locomotor training sessions over the course of the year (range 226-397 sessions) results in decreased annual locomotor training costs (i.e., net savings) between $1114 to $4784 per annum. The base case shows small savings that are sensitive to parameters of the BIA model which were tested in one-way sensitivity analyses, scenarios analyses, and probability sensitivity analyses. The base case scenario was more sensitive to clinical utilization parameters (e.g., how often devices sit idle and the substitution of high cost training) than device-specific parameters (e.g., robotic exoskeleton device cost or device life). Probabilistic sensitivity analysis simultaneously considered human capital cost, device cost, and locomotor device substitution. With probabilistic sensitivity analysis, the introduction of a robotic exoskeleton only remained cost saving for one facility. CONCLUSIONS: Providing robotic exoskeleton for over-ground training was associated with lower costs for the locomotor training of people with SCI in the base case analyses. The analysis was sensitive to parameter assumptions.

Measuring human capital: a systematic analysis of 195 countries and territories, 1990-2016.

BACKGROUND: Human capital is recognised as the level of education and health in a population and is considered an important determinant of economic growth. The World Bank has called for measurement and annual reporting of human capital to track and motivate investments in health and education and enhance productivity. We aim to provide a new comprehensive measure of human capital across countries globally. METHODS: We generated a period measure of expected human capital, defined for each birth cohort as the expected years lived from age 20 to 64 years and adjusted for educational attainment, learning or education quality, and functional health status using rates specific to each time period, age, and sex for 195 countries from 1990 to 2016. We estimated educational attainment using 2522 censuses and household surveys; we based learning estimates on 1894 tests among school-aged children; and we based functional health status on the prevalence of seven health conditions, which were taken from the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016). Mortality rates specific to location, age, and sex were also taken from GBD 2016. FINDINGS: In 2016, Finland had the highest level of expected human capital of 28·4 health, education, and learning-adjusted expected years lived between age 20 and 64 years (95% uncertainty interval 27·5-29·2); Niger had the lowest expected human capital of less than 1·6 years (0·98-2·6). In 2016, 44 countries had already achieved more than 20 years of expected human capital; 68 countries had expected human capital of less than 10 years. Of 195 countries, the ten most populous countries in 2016 for expected human capital were ranked: China at 44, India at 158, USA at 27, Indonesia at 131, Brazil at 71, Pakistan at 164, Nigeria at 171, Bangladesh at 161, Russia at 49, and Mexico at 104. Assessment of change in expected human capital from 1990 to 2016 shows marked variation from less than 2 years of progress in 18 countries to more than 5 years of progress in 35 countries. Larger improvements in expected human capital appear to be associated with faster economic growth. The top quartile of countries in terms of absolute change in human capital from 1990 to 2016 had a median annualised growth in gross domestic product of 2·60% (IQR 1·85-3·69) compared with 1·45% (0·18-2·19) for countries in the bottom quartile. INTERPRETATION: Countries vary widely in the rate of human capital formation. Monitoring the production of human capital can facilitate a mechanism to hold governments and donors accountable for investments in health and education.

Associations Between Insurance Provider and Assistive Technology Use for Computer and Electronic Devices 1 Year After Tetraplegia: Findings From the Spinal Cord Injury Model Systems National Database.

OBJECTIVE: To investigate the association between insurance provider and reported assistive technology (AT) use to access computers and electronic devices 1 year after sustaining tetraplegia. DESIGN: Multicenter cross-sectional study. SETTING: Participants enrolled in the Spinal Cord Injury Model Systems (SCIMS) National Database. INTERVENTIONS: Not applicable. PARTICIPANTS: Men and women with tetraplegia (N=498) enrolled in the SCIMS National Database were included in the analysis. MAIN OUTCOME MEASURES: The primary study outcome was the use of AT when operating a computer or other mobile electronic device. The primary predictor was the subject's principal health insurance provider, which was grouped into the 3 categories: government (Medicare, Medicaid, and other government), private (private insurance, private funds, and other), and workers' compensation. RESULTS: Overall, 34.7% of participants reported using AT to access computers and electronic devices. Results of logistic regression analysis revealed sex, injury level, injury completeness, self-perceived health status, and 12-month history of pressure ulcer were all significantly associated with AT use. After adjusting for these factors, participants with workers' compensation were more likely to report AT use than individuals with either government or private insurance. CONCLUSIONS: Despite significant technological advances, AT is not readily available to the people who might benefit most from its use. Findings from the present study are the first to shed light on AT funding sources and reveal that individuals with workers' compensation are more likely use AT than individuals with either government or private insurance. Additional work focused on AT use and functional outcomes is needed to assess the effect of barriers to use. Collectively, this work may inform insurers of the importance of having AT available for this unique population to potentially improve quality of life and participation.

WORKPLACE INCIVILITY EXPERIENCED BY HEALTH ADMINISTRATION FACULTY.

Workplace incivility is low-intensity, nonspecific, discourteous behavior towards others and may negatively affect employee and organizational outcomes. This exploratory study sought to examine the prevalence of and factors related to experiencing several different types of workplace incivility using a national sample of Health Administration full-time faculty members in the United States. We found that 27-36% of respondents have experienced at least one type of uncivil behavior from students, coworkers, or supervisors. Further, 4-9% of faculty respondents experience such incidents frequently. Faculty respondents who experienced workplace incivility were significantly more likely to report lower job satisfaction and indicated an intention to leave their position within the next three years. Academic leaders should work to foster an environment where incivility towards others is actively discouraged, as it may contribute to dissatisfaction and turnover.

Connectomic correlates of response to treatment in first-episode psychosis.

Connectomic approaches using diffusion tensor imaging have contributed to our understanding of brain changes in psychosis, and could provide further insights into the neural mechanisms underlying response to antipsychotic treatment. We here studied the brain network organization in patients at their first episode of psychosis, evaluating whether connectome-based descriptions of brain networks predict response to treatment, and whether they change after treatment. Seventy-six patients with a first episode of psychosis and 74 healthy controls were included. Thirty-three patients were classified as responders after 12 weeks of antipsychotic treatment. Baseline brain structural networks were built using whole-brain diffusion tensor imaging tractography, and analysed using graph analysis and network-based statistics to explore baseline characteristics of patients who subsequently responded to treatment. A subgroup of 43 patients was rescanned at the 12-week follow-up, to study connectomic changes over time in relation to treatment response. At baseline, those subjects who subsequently responded to treatment, compared to those that did not, showed higher global efficiency in their structural connectomes, a network configuration that theoretically facilitates the flow of information. We did not find specific connectomic changes related to treatment response after 12 weeks of treatment. Our data suggest that patients who have an efficiently-wired connectome at first onset of psychosis show a better subsequent response to antipsychotics. However, response is not accompanied by specific structural changes over time detectable with this method.

Experience of Robotic Exoskeleton Use at Four Spinal Cord Injury Model Systems Centers.

BACKGROUND AND PURPOSE: Refinement of robotic exoskeletons for overground walking is progressing rapidly. We describe clinicians' experiences, evaluations, and training strategies using robotic exoskeletons in spinal cord injury rehabilitation and wellness settings and describe clinicians' perceptions of exoskeleton benefits and risks and developments that would enhance utility. METHODS: We convened focus groups at 4 spinal cord injury model system centers. A court reporter took verbatim notes and provided a transcript. Research staff used a thematic coding approach to summarize discussions. RESULTS: Thirty clinicians participated in focus groups. They reported using exoskeletons primarily in outpatient and wellness settings; 1 center used exoskeletons during inpatient rehabilitation. A typical episode of outpatient exoskeleton therapy comprises 20 to 30 sessions and at least 2 staff members are involved in each session. Treatment focuses on standing, stepping, and gait training; therapists measure progress with standardized assessments. Beyond improved gait, participants attributed physiological, psychological, and social benefits to exoskeleton use. Potential risks included falls, skin irritation, and disappointed expectations. Participants identified enhancements that would be of value including greater durability and adjustability, lighter weight, 1-hand controls, ability to navigate stairs and uneven surfaces, and ability to balance without upper extremity support. DISCUSSION AND CONCLUSIONS: Each spinal cord injury model system center had shared and distinct practices in terms of how it integrates robotic exoskeletons into physical therapy services. There is currently little evidence to guide integration of exoskeletons into rehabilitation therapy services and a pressing need to generate evidence to guide practice and to inform patients' expectations as more devices enter the market.Video Abstract available for more insights from the authors (see Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A231).

Evaluation of the graded redefined assessment of strength, sensibility and prehension (GRASSP) in children with tetraplegia.

STUDY DESIGN: Psychometric study. OBJECTIVE: To validate the GRASSP in pediatric SCI populations and establish the lower age of test administration. SETTING: United States: Pennsylvania, Maryland, Illinois, Michigan, California, Texas. METHODS: Mean, SD and range of scores were calculated and examined for known-group differences. Test-retest reliability was measured by the intra-class correlation, concurrent validity of the GRASSP against the SCIM, SCIM-SS, and the CUE-Q was measured by the Spearman correlation. RESULTS: GRASSP scores differed between participants with motor complete and incomplete injuries (p = <0.0001-0.036). Test-retest reliability was strong (ICC = 0.99). Weak correlation with the total SCIM (r = 0.33-0.66), and moderate to strong correlation with the SCIM-SC (r = 37-0.70) and CUE-Q (r = 0.40-0.84). CONCLUSION: Results support the validity of the GRASSP and provide evidence that the scores are reliable when administered to children. The GRASSP sensory and strength subtests are recommended for children beginning at 6 years of age, and the GRASSP prehension performance/ability subtest for children beginning at 8 years of age. Normative data are needed for the performance components of the GRASSP.

Despite limitations in content range, the SCIM-III is reproducible and a valid indicator of physical function in youths with spinal cord injury and dysfunction.

STUDY DESIGN: Multi-center, repeated measures OBJECTIVES: Evaluate psychometric properties of the SCIM-III in children. SETTING: Seven facilities in North America METHODS: One-hundred and twenty-seven youths, mean age of 10.8 years and chronic spinal cord injury/dysfunction completed two administrations of the Spinal Cord Independence Measure-III (SCIM-III). Mean, standard deviation, range values were calculated for SCIM-III total and subscales for the entire sample, four age groups and injury characteristics. Test-retest reliability, concurrent validity, and floor and ceiling effects were examined. RESULTS: Total SCIM-III and self-care (SC) subscale scores for the youngest age group were lower than those for the three older age groups. There were statistically significant differences in SC subscale scores between neurological level (NL) C5-T1 and T2 -T12; C5-T1 and L1-S4/5; and T2-T12 and L1-S4/5 and in in-room, and indoor/outdoor mobility subscale scores between C1-C4 and T2-T12; C1-C4 and L1-S4/5; C5-T1 and T2-T12; C5-T1 and L1-S4/5; and T2-T12 and L1-S4/5. All scores between motor complete and motor incomplete differed. Test-retest reliability was good (ICC values = > 0.84) and there was moderate to strong correlation between SCIM-III and the FIM® Instrument (r = 0.77-0.92). Ceiling effects were present in the SC subscale for the oldest age group (24%) and for NL L1-S4/5 (35.5%) and in in-room mobility subscale for 6-12 (45.7%), 13-15 (30.43%) and 16-17 (60%) ages, paraplegia (42.4%), tetraplegia (37.1%), incomplete injuries (50%), and T2-T12 (38%) and L1-S4/5 (100%) NL. CONCLUSION: Despite limitations in content range, the SCIM-III is reproducible, and a valid indicator of physical functioning in youth with SCI/D 6 years of age and older. SPONSORSHIP: The study was funded by the Craig H. Neilsen Foundation, Spinal Cord Injury Research on the Translation Spectrum, Senior Research Award Grant #282592 (Mulcahey, PI).
