Objective Assess the utility of the admission Spinal Cord Injury Pressure Ulcer Scale (SCIPUS), Braden Scale, and the FIM for identifying individuals at risk for developing pressure injury during inpatient spinal cord injury (SCI) rehabilitation. Design Retrospective cohort. Setting Two tertiary rehabilitation centers. Participants Individuals (N=754) participating in inpatient SCI rehabilitation. Interventions Not applicable. Main Outcome Measures Logistic regression analysis was performed to determine the utility of the SCIPUS, Braden Scale, and FIM for identifying individuals at risk for developing pressure injury (PI) during inpatient SCI rehabilitation. Sensitivity, specificity, positive predictive value, negative predictive value, false negative rate, odds ratio, likelihood ratio, and area under the curve (AUC) are reported. Results The SCIPUS total score and its individual items did not demonstrate acceptable accuracy (AUC≥0.7) whereas the Braden Scale (0.73) and the FIM score (0.74) did. Once items were dichotomized into high and low risk categories, 1 Braden item (friction and shear), 5 FIM items (bathing, toileting, bed/chair transfer, tub/shower transfer, toilet transfer), the FIM transfers subscale, FIM Motor subscale, and the FIM instrument as a whole, maintained AUCs ≥0.7 and negative predictive values ≥0.95. The FIM bed/chair transfer score demonstrated the highest likelihood ratio (2.62) and overall was the most promising measure for determining PI risk. Conclusion Study findings suggest that a simple measure of mobility, admission FIM bed/chair transfer score of 1 (total assist), can identify at-risk individuals with greater accuracy than both an SCI specific instrument (SCIPUS) and a PI specific instrument (Braden). The FIM bed/chair transfer score can be readily determined at rehabilitation admission with minimal administrative and clinical burden.

To assess the psychometric properties of the Spinal Cord Injury Pressure Ulcer Scale (SCIPUS) for pressure ulcer (PU) risk assessment during inpatient rehabilitation.Prospective cohort.Tertiary rehabilitation centers.Individuals (N=759) participating in inpatient spinal cord injury rehabilitation between January 3, 2012, and April 23, 2014.Not applicable.Admission SCIPUS scores and the corresponding risk stratification, PU incidence, intraclass correlation coefficient (ICC) for interrater reliability, sensitivity, specificity, and likelihood ratios (LRs). Receiver operating characteristic analysis was performed to calculate the area under the curve (AUC).Mean SCIPUS scores were higher for individuals who developed PUs than for those who did not (mean SCIPUS score, 9.8±2.5 vs 8.5±2.6). Interrater reliability was excellent for SCIPUS composite scores (ICC=.91) and very good for risk stratification (ICC=.86). Using the existing cutoff value of ≥6 for "high risk" category, sensitivity and specificity were estimated to be .97 and .12, respectively, with an LR of 1.1. A cutoff value of ≥8 yielded a better balance between sensitivity and specificity (.85 and .38, respectively). The AUC equaled .64 with an LR of 1.4. Results were similar when the analysis was confined to PUs of stage II or greater.The psychometric properties of the SCIPUS do not currently support its routine use as a measure of PU risk in individuals with spinal cord injury undergoing inpatient rehabilitation. LRs of2 indicate that stratification as high risk or very high risk does not substantially increase the likelihood of identifying individuals who develop PUs beyond chance alone. AUCs were also below the desired cutoff value of 0.7.

Objective To develop a physical functioning measure through Rasch analysis conceptualized using the International Classification of Functioning, Disability and Health (ICF). Design Observational cohort study. Setting Acute-hospital and community-based study. Participants Subjects (N=235) hospitalized with postacute stroke and reassessed in the community at 3-months (mean age, 71.6±12.9y). Interventions None. Main Outcome Measures Functional assessments 3 months poststroke included self-report and observational indices and tests commonly used to evaluate stroke survivors. Sociodemographic information was also collected. Rasch analysis assisted in combining the items across ICF components to develop the measure. Items were retained based on fit to the model and relationship to the construct; reliability and validity were assessed. Results The best 44 items formed the Physical Functioning Measure at 3 months (F3m) measure of functioning evaluating limb movement, balance, activities of daily living, and participation. All Rasch model assumptions were met. Both item and person reliably (.96) indicated a stable hierarchy, while precision varied from .51 to 1.2 logits. Early evidence for construct validity is adequate. Conclusions The F3m combines patient reported and observed ratings of performance items into a single measure quantifying functioning with good preliminary psychometric properties that with further testing can assist in directing and evaluating interventions and recovery.

Salbach NM, Mayo NE, Higgins J, Ahmed S, Finch LE, Richards CL. Responsiveness and predictability of gait speed and other disability measures in acute stroke. Arch Phys Med Rehabil 2001;82;1204-12. Objectives: To identify the most responsive method of measuring gait speed, to estimate the responsiveness of other outcome measures, and to determine whether gait speed predicts discharge destination in acute stroke. Design: A prospective cohort study. Setting: Five acute-care hospitals. Patients: Fifty subjects with residual gait deficits after a first-time stroke. Interventions: Five- (5mWT) and 10-meter walk tests (10mWT) at comfortable and maximum speeds, with 2 evaluations conducted an average ± standard deviation (SD) of 8 ± 3 and 38 ± 5 days poststroke. Main Outcome Measure: Standardized response mean (SRM = mean change/SD of change) was used to estimate responsiveness for each walk test, the Berg Balance Scale, the Barthel Index, the Stroke Rehabilitation Assessment of Movement (STREAM), and the Timed Up and Go (TUG). Results: The SRMs were 1.22 and 1.00 for the 5mWT, and .92 and .83 for the 10mWT performed at a comfortable and maximum pace, respectively. The SRMs for the Berg Balance Scale, the Barthel Index, the STREAM, and the TUG were 1.04, .99, .89, and .73, respectively. The probability of discharge to a rehabilitation center for persons walking at ≤ 0.3m/s or > 0.6m/s at the first evaluation was .95 and .22, respectively. Conclusions: The 5mWT at a comfortable pace is recommended as the measure of choice for clinicians and researchers who need to detect longitudinal change in walking disability in the first 5 weeks poststroke. © 2001 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation
