RESUMO
PURPOSE: Lower extremity physical function (LEPF) is a key component for mobility and is impacted in stroke-related disability. A reduction in LEPF can have a significant impact on an individual's Quality of Life (QoL). The aim of this study is to characterise the relationship between LEPF and QoL. METHODS: The MOBITEC-Stroke Study is a longitudinal cohort-study including patients with their first occurrence of ischaemic stroke. Using a linear mixed-effects model, the relationship between LEPF (timed up-and-go performance (TUG); predictor) and QoL (Stroke Specific Quality of Life scale (SS-QoL); outcome) at 3 and 12 months post stroke was investigated and adjusted for sex, age, Instrumental Activities of Daily Living (IADL), fear of falling (Falls Efficacy Scale-International Version, FES-I), and stroke severity (National Institute of Stroke Severity scale, NIHSS), accounting for the repeated measurements. RESULTS: Data of 51 patients (65 % males, 35% females) were analysed. The mean age was 71.1 (SD 10.4) years, median NIHSS score was 2.0. SS-QoL was 201.5 (SD 20.5) at 3 months and 204.2 (SD 17.4) at 12 months; the mean change was 2.7 (95% CI -2.4 to 7.7), p= 0.293. A positive association was found between baseline TUG performance (estimate log score -13.923; 95% CI -27.495 to -0.351; p=0.048) and change in SS-QoL score in multivariate regression analysis. CONCLUSION: Higher LEPF (i.e better TUG performance) at baseline, was associated with an improvement in QoL from 3- to 12-months post stroke. These results highlight the critical role of physical function, particularly baseline LEPF, in influencing the QoL of stroke survivors.
RESUMO
OBJECTIVE: To investigate the parallel-forms reliability, minimal detectable change with 95% confidence interval (MDC95), and feasibility of the 4 telerehabilitation version mobility-related function scales: Fugl-Meyer Assessment-lower extremity subscale (Tele-FMA-LE), Berg Balance Scale (Tele-BBS), Tinetti Performance Oriented Mobility Assessment-Gait subscale (Tele-POMA-G), and Rivermead Mobility Index (Tele-RMI). DESIGN: Reliability and agreement study and cross-sectional study. SETTING: Medical center. PARTICIPANTS: Stroke survivors' ability to independently walk 3 meters with assistive devices, age of ≥18 years for participants and their partners, stable physical condition, and absence of cognitive impairment (N=60). INTERVENTIONS: Not applicable. MAIN OUTCOMES MEASURES: Parallel-forms reliability and MDC95 of Tele-FMA-LE, Tele-BBS, Tele-POMA-G, and Tele-RMI. RESULTS: No significant differences (P>.05) were observed among the mean scores of the telerehabilitation version and face-to-face version mobility-related function scales. Intraclass correlation coefficients (ICCs) indicated good reliability for most scales, with Tele-FMA-LE, Tele-BBS, and Tele-RMI scores achieving values of 0.81, 0.78, and 0.84. Tele-POMA-G scores demonstrated moderate reliability (ICC=0.72). Weighted kappa (κw) showed good-to-excellent reliability for most individual items (κw>0.60). The MDCs of the Tele-FMA-LE, Tele-BBS, Tele-POMA-G, and Tele-RMI were 5.84, 8.10, 2.74, and 1.31, respectively. Bland-Altman analysis showed adequate agreement between tele-assessment and face-to-face assessment for all scales. The 5 dimensions affirm the robust feasibility of tele-assessment: assessment time, subjective fatigue perception, overall preference, participant satisfaction, and system usability. CONCLUSIONS: The study demonstrates good parallel-forms reliability, MDC, and promising feasibility of the 4 telerehabilitation version mobility-related function scales (Tele-FMA-LE, Tele-BBS, Tele-POMA-G, and Tele-RMI) in survivors of stroke.

OBJECTIVE: To identify clinically meaningful thresholds of leg power impairment identified by the stair climb power test (SCPT). DESIGN: Cross-sectional analysis using the baseline data from an observational cohort study. SETTING: The Boston Rehabilitative Impairment Study of the Elderly. PARTICIPANTS: Community-dwelling older adults (N=413). MAIN OUTCOME MEASURES: SCPT and the Short Physical Performance Battery (SPPB). RESULTS: Using the receiver operating characteristic curves and Youden's J statistics, the optimal threshold for the SCPT associated with mobility limitation as defined by an SPPB score ≤9 was 3.07 Watts/kg for men with a sensitivity of 74%, a specificity of 73% and, an area under the curve (AUC) value of 0.78. For women, the optimal threshold was 2.59 Watts/kg with a sensitivity of 83%, a specificity of 69%, and an AUC value of 0.81. The classification and regression tree sensitivity analysis demonstrated similar thresholds, 2.88 Watts/kg and 2.53 Watts/kg for men and women, respectively. CONCLUSIONS: The study identified clinically meaningful thresholds of impairment for the SCPT for mobility limited older primary care patients. These thresholds may be used to inform rehabilitation care to improve functional mobility of older adults and should be validated in larger more representative clinical trials.

BACKGROUND: We assessed whether clinical, functional and behavioral factors were associated with the decrease in mobility trajectories reported in older people at risk of sarcopenia (RS) and without risk of sarcopenia (NRS) during COVID-19 pandemic. METHODS: We prospectively analyzed mobility trajectories reported in older adults with RS and NRS over 16-month follow-up (Remobilize study). The self-perceived risk of sarcopenia and mobility were assessed using the SARC-F and the Life-Space Assessment (LSA) tools, respectively. Gender, age, comorbidities, pain, functional limitation, physical activity (time spent in walking; min/week), and sitting time (ST; hours/day) were assessed. We used a multilevel model to determine changes in mobility between groups and over time. RESULTS: Mobility was lower in RS than in NRS. Older people at RS, who were women, aged 70-79 years and 80 years or older, inactive, and with moderate to severe functional limitation experienced reduced mobility trajectories reported over the pandemic. For older people at NRS, trajectories with reduce mobility reported were experienced by women with comorbidities, for those with insufficient walking time and aged 70-79 years; aged 70-79 years and with ST between 5 and 7 hours/day; for those with insufficient walking time and increased ST; and for those with pain and increased ST. CONCLUSION: Mobility trajectories reported in older people at risk of sarcopenia were negatively influenced by insufficient level of physical inactivity and pre-existing moderate to severe functional limitation. Health and social interventions should be target to avoid mobility limitation during and after the COVID-19 pandemic.

BACKGROUND: This study aimed to investigate the relationship between femoral neck fractures and sarcopenia. METHODS: This was a retrospective analysis of 92 patients with femoral neck fractures, from September 2017 to March 2020, who were classified into high ambulatory status (HG) and low ambulatory status (LG) groups. Ambulatory status was assessed before surgery, one week after surgery, at discharge, and during the final follow-up. To evaluate sarcopenia, muscle mass and fatty degeneration of the muscles were measured using preoperative CT. An axial slice of the superior end of the L5 vertebra was used to evaluate the paraspinal and psoas muscles, a slice of the superior end of the femoral head for the gluteus maximus muscle, and a slice of the inferior end of the sacroiliac joint for the gluteus medius muscle. The degeneration of the muscles was evaluated according to the Goutallier classification. RESULTS: The cross-sectional area of the gluteus medius and paraspinal muscles was significantly correlated with ambulatory status before the injury, at discharge, and during the final follow-up. CONCLUSIONS: Measurement of the gluteus medius and paraspinal muscles has the potential to evaluate sarcopenia and predict ambulatory status after femoral neck fractures.

Dysphagia or swallowing dysfunction is associated with reduced quality of life and poor long term outcomes. While standard dysphagia treatment focuses on improving swallowing function, it is not clear if people with dysphagia also have difficulties performing daily tasks. This study aimed to determine if individuals with dysphagia had difficulties with participating in daily tasks requiring physical function, as compared to those with no dysphagia. We conducted a secondary data analysis using the responses of 24,107 adults aged 18 years or older who completed the 2022 National Health Interview Survey. The independent variable was report of swallowing problem during the past 12 months, and the dependent variables were report of difficulty in physical function tasks (e.g., self-care, mobility, working, social participation). We utilized propensity score methods to balance demographic and clinical variables between groups, and examined if individuals with dysphagia had more difficulties with the physical function tasks. The propensity score methods balanced the demographic and clinical variables (absolute standardized differences < 0.1). People with dysphagia had significantly higher odds ratios (ranged from 1.23 to 1.70, all p < 0.05) of having difficulties in physical function tasks than those without dysphagia. The findings revealed an association between experiencing dysphagia and encountering difficulties in self-care, mobility, working, and social participation in the general adult population in the US. Results of our study indicate that during the course of rehabilitation, healthcare professionals should consider the potential impact of dysphagia symptoms on clients' ability to partake in independent activities in their community settings.
RESUMO
AIMS: The study aimed to describe the implementation of a collaborative ride-on car (ROC) intervention by applying a practice model of family-professional collaboration. The model involves specific strategies for collaboration, "visualizing a preferred future" and "scaling questions." METHODS: The participants were two young children with mobility limitations and their mothers. The 12-week of ROC intervention involved training sessions with a therapist and home sessions. The outcomes included the Canadian Occupational Performance Measure (COPM) and Goal Attainment Scaling (GAS). RESULTS: The collaborative strategies facilitated parent engagement in goal setting, planning, and evaluation. After the intervention, the mothers' ratings of their children's performance and parent satisfaction on the COPM increased by 6 and 3 points, respectively, and the level of goal attainment exceeded expectations (+1 on GAS) in both families. Prior to the ROC intervention, both families were hesitant to use powered mobility. However, the experience of participating in the ROC intervention process broadened parents' perspectives on self-directed mobility and led them to explore options for their children to move independently. CONCLUSIONS: The collaborative ROC intervention can be used as an intervention for early mobility and a bridging step for families reluctant to use a powered wheelchair.

BACKGROUND: Nursing students often receive insufficient training in older adults' care. PURPOSE: Examine nursing students' perceptions of an e-learning module developed to enhance their knowledge about the comfort, safety, and mobility of older adults. METHODS: A cross-sectional survey was administered to third-year baccalaureate nursing students at a Canadian university after they had completed the comfort, safety, and mobility module. The survey assessed students' perceptions of the e-learning module using four 5-pointLikert-type items. The survey also contained demographic questions and one open-ended question that invited participants to make any comments they wished. Descriptive statistics were used to summarize participants'demographic characteristics. Responses to the open-ended quesiton were summative content analyzed. RESULTS: The survey was completed by 119 participants, who reported that the module increased their confidence, perceptions and knowledge in working with older adults. Participants also found the method of instruction to be convenient, interactive, and enjoyable. CONCLUSIONS: Results suggest that the learning module has the potential to facilitate student nurses' learning about comfort, safety, and mobility.
RESUMO
OBJECTIVE: To determine how often physicians document mobility limitations in visits with older adults, and which patient, physician, and practice characteristics associate with documented mobility limitations. DESIGN: We completed a cross-sectional analysis of National Ambulatory Medical Care Surveys, years 2012-2016. Multivariate analyses were conducted to identify patient, physician, and practice-level factors associated with mobility limitation documentation. SETTING: Ambulatory care visits. PARTICIPANTS: We analyzed visits with adults 65 years and older. Final sample size represented 1.3 billion weighted visits. INTERVENTION: Not applicable. MAIN OUTCOME MEASURE: We defined the presence/absence of a mobility limitation by whether any International Classification of Diseases (ICD)-9 or ICD-10 code related to mobility limitations, injury codes, or the patient's "reasons for visit" were documented in the visits. RESULTS: The overall prevalence of mobility limitation documentation was 2.4%. The most common codes were falls-related. Patient-level factors more likely to be associated with mobility limitation documentation were visits by individuals over 85 years of age, relative to 65-69 years, (odds ratio 2.32, 95% confidence interval 1.76-3.07]; with a comorbid diagnosis of arthritis (odds ratio 1.35, 1.18-2.01); and with a comorbid diagnosis of cerebrovascular disease (odds ratio 1.60, 1.13-2.26). Patient-level factors less likely to be associated with mobility limitation documentation were visits by men (odds ratio 0.80, 0.64-0.99); individuals with a cancer diagnosis (odds ratio 0.76, 0.58-0.99); and by individuals seeking care for a chronic problem (relative to a new problem [odds ratio 0.36, 0.29-0.44]). Physician-level factors associated with an increased likelihood of mobility limitation documentation were visits to neurologists (odds ratios 4.48, 2.41-8.32) and orthopedists (odds ratio 2.67, 1.49-4.79) compared with primary care physicians. At the practice-level, mobility documentation varied based on the percentage of practice revenue from Medicare. CONCLUSIONS: Mobility limitations are under-documented and may be primarily captured when changes in function are overt.

BACKGROUND: Mobility is a key determinant and outcome of healthy ageing but its definition, conceptual framework and underlying constructs within the physical domain may need clarification for data comparison and sharing in ageing research. This study aimed to (1) review definitions and conceptual frameworks of mobility, (2) explore agreement on the definition of mobility, conceptual frameworks, constructs and measures of mobility, and (3) define, classify and identify constructs. METHODS: A three-step approach was adopted: a literature review and two rounds of expert questionnaires (n = 64, n = 31, respectively). Agreement on statements was assessed using a five-point Likert scale; the answer options 'strongly agree' or 'agree' were combined. The percentage of respondents was subsequently used to classify agreements for each statement as: strong (≥ 80%), moderate (≥ 70% and < 80%) and low (< 70%). RESULTS: A variety of definitions of mobility, conceptual frameworks and constructs were found in the literature and among respondents. Strong agreement was found on defining mobility as the ability to move, including the use of assistive devices. Multiple constructs and measures were identified, but low agreements and variability were found on definitions, classifications and identification of constructs. Strong agreements were found on defining physical capacity (what a person is maximally capable of, 'can do') and performance (what a person actually does in their daily life, 'do') as key constructs of mobility. CONCLUSION: Agreements on definitions of mobility, physical capacity and performance were found, but constructs of mobility need to be further identified, defined and classified appropriately. Clear terminology and definitions are essential to facilitate communication and interpretation in operationalising the physical domain of mobility as a prerequisite for standardisation of mobility measures.

BACKGROUND: Mobility limitation-the loss of exercise capacity or independent living ability-is a common geriatric syndrome in older adults. As a potentially reversible precursor to disability, mobility limitation is influenced by various factors. Moreover, its complex physiological mechanism hinders good therapeutic outcomes with a single-factor intervention. Most hospitals have not incorporated the diagnosis and evaluation of mobility limitation into medical routines nor developed a multidisciplinary team (MDT) treatment plan. We aim to conduct a clinical trial titled "A Multidisciplinary-team approach for management of Mobility Limitation in Elderly (M-MobiLE)" to explore the effect of the MDT decision-making intervention for mobility limitation. METHODS: The M-MobiLE study will be a multicenter, randomized, and controlled trial. We will recruit a minimum of 66 older inpatients with mobility limitation from at least five hospitals. Older patients with mobility limitation admitted to the geriatrics department will be included. Short-Physical Performance Battery (SPPB), Activities of Daily Living (ADL), Function Impairment Screening Tool (FIST), Geriatric Depression Scale (GDS-15), Short Form - 12 (SF-12), Fried frailty phenotype, social frailty, Morse Fall Risk Scale, SARC-CalF, Mini-Mental State Examination (MMSE), Mini-Nutritional Assessment Short-Form (MNA-SF), and intrinsic capacity will be assessed. The intervention group will receive an exercise-centered individualized MDT treatment, including exercise, educational, nutritional, medical, and comorbidity interventions; the control group will receive standard medical treatment. The primary outcome is the change in the SPPB score, and the secondary outcomes include increased SF-12, ADL, FIST, MMSE, MNA-SF, and intrinsic capacity scores and decreased GDS-15 and SARC-CalF scores. CONCLUSION: Our results will help develop a multidisciplinary decision-making clinical pathway for inpatients with mobility limitation, which can be used to identify patients with mobility limitation more effectively, improve mobility, and reduce the risk of falls, frailty, and death in older inpatients. The implementation of this MDT strategy may standardize the treatment of mobility limitation, reduce adverse prognosis, and improve quality of life.

BACKGROUND: The high prevalence of depression among older people in China places a heavy burden on the health system. Multimorbidity, mobility limitation and subjective memory impairment are found to be risk indicators for depression. However, most studies on this topic focused on depression at a single point in time, ignoring the dynamic changes in depressive symptoms and the relationship between the trajectories and these three conditions. Therefore, we aimed to identify distinct trajectories of depressive symptoms in older people and investigate their associations with multimorbidity, mobility limitation and subjective memory impairment. METHODS: Data was drawn from China Health and Retirement Longitudinal Study conducted during 2011-2018. A total of 5196 participants who completed 4 visits, conducted every 2-3 years were included in this study. Group-based trajectory modeling was conducted to identify distinct trajectories of depressive symptoms z-scores. Multinomial logistic regression was used to investigate the relationships. RESULTS: Four distinct trajectories of depressive symptoms z-scores were identified, labeled as persistently low symptoms (68.69%, n = 3569), increasing symptoms (12.14%, n = 631), decreasing symptoms (14.05%, n = 730) and persistently high symptoms (5.12%, n = 266). Participants with multimorbidity had unfavorable trajectories of depressive symptoms compared with those without multimorbidity, with adjusted odds ratios (95% CIs) of 1.40 (1.15, 1.70), 1.59 (1.33, 1.90) and 2.19 (1.65, 2.90) for the increasing symptoms, decreasing symptoms and persistently high symptoms, respectively. We also observed a similar trend among participants with mobility limitations. Compared with participants who had poor subjective memory, participants with excellent/very good/good subjective memory had a lower risk of developing unfavorable trajectories of depressive symptoms. The adjusted odds ratios (95% CIs) of the increasing symptoms, decreasing symptoms and persistently high symptoms were 0.54 (0.40, 0.72), 0.50 (0.38, 0.65) and 0.48 (0.31, 0.73), respectively. CONCLUSIONS: Multimorbidity, mobility limitation and subjective memory impairment were found to be potential risk factors for unfavorable depression trajectories.

BACKGROUND: In older adults, mobility is important for maintaining their independence and quality of life, and it influences their physical, cognitive, and social health. This study aimed to identify the physical and psychosocial factors that affected the mobility of community-dwelling older adults, aged 65 years or older, who were socially isolated during the coronavirus disease 2019 (COVID-19) pandemic due to stay-at-home policies. METHODS: The participants in this study were 214 community-dwelling older adults in Korea, and a cross-sectional survey was conducted from December 2020 to January 2021. Variables included participants' general characteristics, mobility, sitting time, depression, social support, and cognitive function. RESULTS: Multiple linear regression analysis showed that the factors influencing older adults' mobility during the COVID-19 pandemic were depression (ß=-0.29, p < .001), age (65-74 years old) (ß = 0.19, p = .002), a lower level of education (ß=-0.17, p = .006), two or more comorbidities (ß=-0.18, p = .001), sitting time (ß=-0.17, p = .004), and the ability to drive a vehicle (ß = 0.14, p = .017). CONCLUSIONS: Home healthcare interventions are needed to limit psychosocial issues and improve mobility for older adults who had limited mobility during the COVID-19 pandemic.

BACKGROUND: Promoting patient mobility helps improve patient outcomes, but mobility status is not widely tracked nor do patients have specific individualized mobility goals. PURPOSE: We evaluated nursing adoption of mobility measures and daily mobility goal achievement using the Johns Hopkins Mobility Goal Calculator (JH-MGC), a tool to guide an individualized patient mobility goal based on the level of mobility capacity. METHOD: Built on a translating research into practice framework, the Johns Hopkins Activity and Mobility Promotion (JH-AMP) program was the vehicle to promote use of the mobility measures and the JH-MGC. We evaluated a large-scale implementation effort of this program on 23 units across two medical centers. FINDINGS: Units significantly improved documentation compliance to mobility measures and achieving daily mobility goals. Units with the highest documentation compliance rates had higher rates of daily mobility goal achievement, especially for longer distance ambulation goals. DISCUSSION: The JH-AMP program improved adoption of mobility status tracking and higher nursing inpatient mobility levels.

This cross-sectional exploratory study investigated factors associated with unrecovered falls among older patients with a history of falls in the previous year participating in a clinical trial on fall prevention by asking them about their inability to get up independently after the fall. Participants' sociodemographic, clinical, functional (ADL/IADL, TUG, chair-stand test, hand grip, risk of falling) and fall location were investigated. We conducted a multivariate regression analysis adjusted for covariates to identify the main factors associated with unrecovered falls. Out of 715 participants (mean age: 73.4 years; 86% women), 51.6% (95% IC; 47.9 - 55.3%) experienced unrecovered falls. Depressive symptoms, ADL/IADL limitation, mobility limitation, undernutrition, and outdoor falls were associated with unrecovered falls. While assessing the risk of falling, professionals should consider preventive strategies and preparedness procedures for those who are more likely to experience unrecovered falls, such as training to get up from the floor, alarms, and support services.

OBJECTIVE: To examine the effects of community-based resistance training (RT) on physical function for older adults with mobility disability. DATA SOURCES: Four databases (PubM, PubMed, MEDLINE, Ovid, Cumulative Index to Nursing and Allied Health, Web of Science) were searched from inception to February 2, 2021. STUDY SELECTION: Randomized controlled trials that examined community-based RT for improving physical function in community-dwelling older adults were included. DATA EXTRACTION: Two reviewers independently conducted title and abstract screening, full-text evaluation, data extraction, and risk of bias quality assessment. DATA SYNTHESIS: Twenty-four studies (3656 participants; age range, 63-83 years) were included. RT programs ranged from 10 weeks to 18 months in duration. RT was more effective than control in improving 6-minute walk test distance (n=638; mean difference [MD], 16.1m; 95% CI, 12.27-19.94; P<.0001), lower extremity strength (n=785; standardized MD, 2.01; 95% CI, 1.27-2.75; P<.0001), and usual gait speed (n= 2106; MD, 0.05 m/s, 95% CI, 0.03-0.07; P<.001). In sensitivity analyses, benefits were maintained when studies with a high risk of bias were excluded. There was no effect of RT on fast gait speed or Short Physical Performance Battery score compared with control. CONCLUSIONS: RT improves walking distance, lower extremity strength, and usual gait speed in older adults with mobility disability. Improvements in physical function could increase independence in activities of daily living for this at-risk population.

OBJECTIVE: To link 3 Spinal Cord Injury-Functional Index (SCI-FI) item banks (Basic Mobility, Fine Motor Function, Self-Care) to the Patient-Reported Outcome Measurement Information System (PROMIS) Physical Function (PF) metric. DESIGN: Observational study SETTING: Six SCI Model Systems rehabilitation hospitals in the United States. PARTICIPANTS: Adults with SCI (n=855) and healthy individuals (n=730) (N=1585). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Three SCI-FI item banks (Basic Mobility, Fine Motor Function, Self-Care), PROMIS PF v1.0 item bank. RESULTS: SCI-FI item banks (including 30 items from the PROMIS PF item bank) were administered to 855 adults with SCI as part of the original SCI-FI development study. The data were used to attempt to link 3 SCI-FI banks to the PROMIS PF metric via 2 item-response theory methods: fixed-parameter calibration and separate calibration. Sixteen items common to SCI-FI and PROMIS and verified as free of differential item functioning were used as anchor items to implement the methods. Of the 3 banks, only SCI-FI Basic Mobility could be linked with sufficient precision to PROMIS PF. Comparisons of actual vs linked PROMIS PF scores and test characteristic curves suggested the fixed-parameter method provided slightly more precision than the separate calibration method. CONCLUSIONS: The linkage between PROMIS PF and SCI-FI Basic Mobility was considered satisfactory for group-level usage. Score equivalents computed from SCI-FI Basic Mobility will be useful for researchers comparing functional levels in SCI to those observed in other clinical and nonclinical groups (eg, in comparative effectiveness research).

OBJECTIVES: To develop clinically relevant interpretive standards for the Spinal Cord Injury-Functional Index/Capacity (SCI-FI/C) Basic Mobility and Self-Care item bank scores. DESIGN: Modified "bookmarking" standard-setting methodology, including 2 stakeholder consensus meetings with individuals with spinal cord injury (SCI) and SCI clinicians, respectively, and a final, combined (consumers and clinicians) "convergence" meeting. SETTING: Two SCI Model System centers in the United States. PARTICIPANTS: Fourteen adults who work with individuals with traumatic SCI and 14 clinicians who work with individuals with SCI. MAIN OUTCOME MEASURES: Placement of bookmarks between vignettes based on SCI-FI Basic Mobility and Self-Care T scores. Bookmarks were placed between vignettes representing "No Problems," "Mild Problems," "Moderate Problems," and "Severe Problems" for each item bank. RESULTS: Each consensus group resulted in a single set of scoring cut points for the SCI-FI/C Basic Mobility and Self-Care item banks. The cut points were similar but not identical between the consumer and clinician groups, necessitating a final convergence meeting. For SCI-FI/C Basic Mobility, the convergence group agreed on cut scores of 61.25 (no problems/mild problems), 51.25 (mild problems/moderate problems), and 41.25 (moderate problems/severe problems). For SCI-FI/C Self-Care, the convergence group agreed on cut scores of 56.25 (no/mild), 51.25 (mild/moderate), and 38.75 (moderate/severe). CONCLUSIONS: The results of this study provide straightforward interpretive guidelines for SCI researchers and clinicians using the SCI-FI/C Basic Mobility and Self-Care instruments. These results are appropriate for the full bank, computer adaptive test, and short-form versions of the SCI-FI/C Basic Mobility and Self-Care item banks.

OBJECTIVE: To explore trajectories of functional recovery that occur during the first 2 years after spinal cord injury (SCI). DESIGN: Observational cohort study. SETTING: Eight SCI Model System sites. PARTICIPANTS: A total of 479 adults with SCI completed 4 Spinal Cord Injury-Functional Index (SCI-FI) item banks within 4 months of injury and again at 2 weeks, 3, 6, 12, and 24 months after baseline assessment (N=479). INTERVENTION: None. MAIN OUTCOME MEASURES: SCI-FI Basic Mobility/Capacity (C), Fine Motor Function/C, Self-care/C, and Wheelchair Mobility/Assistive Technology (AT) item banks. RESULTS: Growth mixture modeling was used to identify groups with similar trajectory patterns. For the Basic Mobility/C and Wheelchair Mobility/AT domains, models specifying 2 trajectory groups were selected. For both domains, a majority class exhibited average functional levels and gradual improvement, primarily in the first 6 months. A smaller group of individuals made gradual improvements but had greater initial functional limitations. The Self Care/C domain exhibited a similar pattern; however, a third, small class emerged that exhibited substantial improvement in the first 6 months. Finally, for individuals with tetraplegia, trajectories of Fine Motor Function/C scores followed 2 patterns, with individuals reporting generally low initial scores and then making either modest or large improvements. In individual growth curve models, injury/demographic factors predicted initial functional levels but less so regarding rates of recovery. CONCLUSIONS: Trajectories of functional recovery followed a small number of change patterns, although variation around these patterns emerged. During the first 2 years after initial hospitalization, SCI-FI scores showed modest improvements; however, substantial improvements were noted for a small number of individuals with severe limitations in fine motor and self-care function. Future studies should further explore the personal, medical, and environmental characteristics that influence functional trajectories during these first 2 years and beyond.

The Spinal Cord Injury-Functional Index (SCI-FI) is a system of patient-reported outcome measures of functional activities developed specifically with and for individuals with spinal cord injury (SCI). The SCI-FI was designed to overcome limitations in measurement of the full range of activities and breadth of content of physical functioning commonly used in SCI research. Generic measurement tools of physical function (ie, those focused on the general population) tend to overemphasize mobility and do not contain enough items at the lower end of the functional range (eg, items appropriate for individuals with tetraplegia). The SCI-FI consists of 9 item response theory-calibrated item banks that represent relevant and meaningful item content for individuals with SCI, span a wide range of functional abilities, and subdivide physical functioning into important subdomains, including basic mobility, self-care, and fine motor function. Since the original publication of the SCI-FI in 2012, there have been significant advances in and publications on the reliability and psychometric properties of the measures. The manuscripts presented in this special section clarify the SCI-FI structure and present new research on the SCI-FI measurement system.
