Occurrence of amyotrophic lateral sclerosis among Gulf War veterans.

BACKGROUND: In response to Gulf War veterans' concerns of high rates of ALS, this investigation sought to determine if Gulf War veterans have an elevated rate of ALS. METHODS: A nationwide epidemiologic case ascertainment study design was used to ascertain all occurrences of ALS for the 10-year period since August 1990 among active duty military and mobilized Reserves, including National Guard, who served during the Gulf War (August 2, 1990, through July 31, 1991). The diagnosis of ALS was confirmed by medical record review. Risk was assessed by the age-adjusted, average, annual 10-year cumulative incidence rate. RESULTS: Among approximately 2.5 million eligible military personnel, 107 confirmed cases of ALS were identified for an overall occurrence of 0.43 per 100,000 persons per year. A significant elevated risk of ALS occurred among all deployed personnel (RR = 1.92; 95% CL = 1.29, 2.84), deployed active duty military (RR = 2.15, 95% CL = 1.38, 3.36), deployed Air Force (RR = 2.68, 95% CL = 1.24, 5.78), and deployed Army (RR = 2.04; 95% CL = 1.10, 3.77) personnel. Elevated, but nonsignificant, risks were observed for deployed Reserves and National Guard (RR = 2.50; 95% CL = 0.88, 7.07), deployed Navy (RR = 1.48, 95% CL = 0.62, 3.57), and deployed Marine Corps (RR = 1.13; 95% CL = 0.27, 4.79) personnel. Overall, the attributable risk associated with deployment was 18% (95% CL = 4.9%, 29.4%). CONCLUSIONS: Military personnel who were deployed to the Gulf Region during the Gulf War period experienced a greater post-war risk of ALS than those who were not deployed to the Gulf.

VA Stroke Study: neurologist care is associated with increased testing but improved outcomes.

OBJECTIVE: VA Stroke Study (VASt) data were analyzed to determine whether neurologist management affected the process and outcome of care of patients with ischemic stroke. METHODS: VASt prospectively identified patients with stroke admitted to nine VA hospitals (April 1995 to March 1997). Demographics, stroke severity (Canadian Neurologic Score), stroke subtype (Trial of ORG 10172 in Acute Stroke Treatment [TOAST] classification), tests/procedures, and discharge status (independent, Rankin < or = 2, vs dead or dependent, Rankin 3 through 5) were compared between patients who were or were not cared for by a neurologist. RESULTS: Of 1,073 enrolled patients, 775 (neurologist care, n = 614; non-neurologist, n = 161) with ischemic stroke were admitted from home. Stroke severity (Canadian Neurologic Score 8.7 +/- 0.1 vs 8.4 +/- 0.2; p = 0.44), TOAST subtype (p = 0.55), and patient age (71.4 +/- 0.4 vs 72.4 +/- 0.7; p = 0.23) were similar for neurologists and non-neurologists. Neurologists more frequently obtained MRI (44% vs 16%; p < 0.001), transesophageal echocardiograms (12% vs 2%; p < 0.001), carotid ultrasounds (65% vs 57%; p = 0.05), cerebral angiography (8% vs 1%; p = 0.001), speech (35% vs 18%; p < 0.001), and occupational therapy (46% vs 33%; p = 0.005) evaluations. Brain CT, transthoracic echocardiogram, 24-hour ambulatory ECG use, and hospitalization durations (18.2 +/- 0.8 vs 19.7 +/- 4.1 days; p = 0.725) were similar. Neurologists' patients were less likely to be dead (5.6% vs 13.5%; OR = 0.38; 95% CI 0.22, 0.68; p = 0.001) and less likely to be dead or dependent (46.1% vs 57.1%; OR = 0.64; 95% CI 0.45, 0.92; p = 0.019) at the time of discharge. The benefit remained after controlling for stroke severity and comorbidity (OR = 0.63; 95% CI 0.42, 0.94; p = 0.025). CONCLUSION: Neurologist care was associated with more extensive testing, but similar lengths of hospitalization and improved outcomes.

Improving the reliability of stroke subgroup classification using the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) criteria.

BACKGROUND AND PURPOSE: We sought to improve the reliability of the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) classification of stroke subtype for retrospective use in clinical, health services, and quality of care outcome studies. The TOAST investigators devised a series of 11 definitions to classify patients with ischemic stroke into 5 major etiologic/pathophysiological groupings. Interrater agreement was reported to be substantial in a series of patients who were independently assessed by pairs of physicians. However, the investigators cautioned that disagreements in subtype assignment remain despite the use of these explicit criteria and that trials should include measures to ensure the most uniform diagnosis possible. METHODS: In preparation for a study of outcomes and management practices for patients with ischemic stroke within Department of Veterans Affairs hospitals, 2 neurologists and 2 internists first retrospectively classified a series of 14 randomly selected stroke patients on the basis of the TOAST definitions to provide a baseline assessment of interrater agreement. A 2-phase process was then used to improve the reliability of subtype assignment. In the first phase, a computerized algorithm was developed to assign the TOAST diagnostic category. The reliability of the computerized algorithm was tested with a series of synthetic cases designed to provide data fitting each of the 11 definitions. In the second phase, critical disagreements in the data abstraction process were identified and remaining variability was reduced by the development of standardized procedures for retrieving relevant information from the medical record. RESULTS: The 4 physicians agreed in subtype diagnosis for only 2 of the 14 baseline cases (14%) using all 11 TOAST definitions and for 4 of the 14 cases (29%) when the classifications were collapsed into the 5 major etiologic/pathophysiological groupings (kappa=0.42; 95% CI, 0.32 to 0.53). There was 100% agreement between classifications generated by the computerized algorithm and the intended diagnostic groups for the 11 synthetic cases. The algorithm was then applied to the original 14 cases, and the diagnostic categorization was compared with each of the 4 physicians' baseline assignments. For the 5 collapsed subtypes, the algorithm-based and physician-assigned diagnoses disagreed for 29% to 50% of the cases, reflecting variation in the abstracted data and/or its interpretation. The use of an operations manual designed to guide data abstraction improved the reliability subtype assignment (kappa=0.54; 95% CI, 0.26 to 0.82). Critical disagreements in the abstracted data were identified, and the manual was revised accordingly. Reliability with the use of the 5 collapsed groupings then improved for both interrater (kappa=0.68; 95% CI, 0.44 to 0.91) and intrarater (kappa=0.74; 95% CI, 0.61 to 0.87) agreement. Examining each remaining disagreement revealed that half were due to ambiguities in the medical record and half were related to otherwise unexplained errors in data abstraction. CONCLUSIONS: Ischemic stroke subtype based on published TOAST classification criteria can be reliably assigned with the use of a computerized algorithm with data obtained through standardized medical record abstraction procedures. Some variability in stroke subtype classification will remain because of inconsistencies in the medical record and errors in data abstraction. This residual variability can be addressed by having 2 raters classify each case and then identifying and resolving the reason(s) for the disagreement.

Accuracy of self-reported stroke among elderly veterans.

The objective was to use secondary analysis of prevalence data from a prospective cohort study to ascertain the accuracy of self-reported stroke among veterans. The study comprised a community-dwelling population of 88 elderly veterans (from five counties in the Northern Piedmont of North Carolina, USA) who received health care at the local Veterans Health Administration (VHA) medical center and were respondents at the North Carolina site of the NIH-funded Established Populations for Epidemiologic Studies of the Elderly (EPESE) project. Self-report of stroke from the baseline interview of the EPESE project; and occurrence of stroke as verified by the national VHA hospital discharge database and the patients' medical records was measured. Results showed that self-report of stroke had a sensitivity of 86% and a specificity of 100%; the predictive value of a positive report was 100%. Veterans' self-reports of stroke are sufficiently accurate to use in preliminary epidemiological studies and health services research of cerebrovascular disease.

Stroke care: a method for measuring compliance with AHCPR guidelines.

The purpose of this article is to describe a method for converting practice guidelines to measurement criteria. To evaluate the processes of care received by patients with stroke at 11 Veteran's Administration hospital sites, we developed a measurement system based on Agency for Health Care Policy and Research (AHCPR) Post-Stroke Rehabilitation Clinical Practice Guidelines. Guideline recommendations were used as the framework for identifying important dimensions of care, and for developing chart abstraction instruments for both the acute and postacute settings. Using a modified Delphi technique to solicit opinions from an expert panel, a method was developed for aggregation of item-level chart abstraction components to overall guideline compliance scores. The measurement system was shown to have good-to-excellent intrarater and interrater reliability at the item, dimension, and overall compliance score levels. Abstraction of a sample of 100 medical records demonstrated the ability of the instruments to detect variability in processes of post-stroke care. This study provides the foundation for future research, which will evaluate associations between processes of post-stroke care, as measured by this medical chart abstraction system, and patient outcomes. (All abstraction instruments, criteria, and scoring algorithms described in this article are available for download at http://www2.kumc.edu/coa.)

Differences in rehabilitation services and outcomes among stroke patients cared for in veterans hospitals.

OBJECTIVE: To examine the relationship of services for post-acute care (PAC) to stroke patient outcomes. DATA SOURCES/STUDY SETTING: Veterans Health Administration (VHA) hospitals from two facility-level surveys and extant data files. STUDY DESIGN: Cross-sectional study of veterans hospitalized with acute stroke during the period June 1995 through May 1996 in one of 182 geographically distinct locations within the VHA. Study variables included (1) a typological classification of hospitals according to the level of PAC; (2) a taxonomy of rehabilitation characteristics, including personnel, physical facilities, coordination of care, and hospital characteristics; and (3) patient outcomes (discharge destination, length of stay). DATA COLLECTION/EXTRACTION METHODS: Data were collected from two mailed surveys and extant data files. Rehabilitation variables were identified for the study in conjunction with a panel of expert rehabilitation researchers and clinicians, using an a priori model for measuring rehabilitation characteristics. Two sets of variables were derived to categorize these rehabilitation characteristics: (1) a rehabilitation typology, classifying the VA hospitals according to the continuum of PAC settings in the facility, and (2) a rehabilitation taxonomy that used an empirical approach to derive a list of key rehabilitation characteristics. PRINCIPAL FINDINGS: Twenty-seven percent of veterans with acute stroke were cared for in VA hospitals with neither a geriatric nor a rehabilitation unit, and 50 percent were cared for in hospitals without a rehabilitation unit. Hospitals with rehabilitation units had the greatest sophistication, and those with geriatric units had intermediate sophistication in rehabilitation organization and resources. Statistically significant differences were found in outcomes for stroke patients cared for in hospitals classified according to the continuum of post-acute care on site. Exploratory multivariable analyses revealed independent associations between stroke patient outcomes and (1) staffing ratios for nurses and physicians, (2) the diversity of physician and rehabilitation staff, (3) presence of a simulated home environment, and (4) the total number of care settings on site. CONCLUSIONS: The PAC continuum defines an important hierarchy of stroke rehabilitation services.

Depression and other determinants of values placed on current health state by stroke patients: evidence from the VA Acute Stroke (VASt) study.

BACKGROUND AND PURPOSE: This prospective study examined the determinants of the utility (value) placed on health status among a sample of patients with acute ischemic and intracerebral hemorrhagic stroke. METHODS: Data were from the VA Acute Stroke (VASt) study, a nationwide prospective cohort of 1073 acute stroke patients admitted at any of 9 Department of Veterans Affairs Medical Center sites between April 1, 1995, and March 31, 1997. The primary outcome was the patient's health status utility as measured by the time-tradeoff method. Data were obtained by telephone interviews at 1, 6, and 12 months and by medical record review. General linear mixed modeling was used to assess the effects of social, psychological, and physical factors on patients' valuations of their current health state. The analysis was confined to the 327 patients who were able to provide self-reports at >/=2 time points. RESULTS: Patients' valuations of their health state status over the initial 12 months after stroke were very stable over time, with only a slight improvement at 6 months, followed by a slight decline at 12 months. In adjusted analyses, living alone, being institutionalized, decreased physical function, and depression were independently associated with lower levels of patient health status utility over time. CONCLUSIONS: Stroke patient health status utilities are relatively stable during the initial year after stroke. In addition to physical function, psychological health and social environment are important determinants of patient health status utility. These factors need to be considered when conducting stroke decision analyses if more accurate conclusions are to be drawn regarding preferred patterns of care.

The structure and structural effects of VA rehabilitation bedservice care for stroke.

The purpose of this study was to: 1) examine the variation in organizational structure within rehabilitation bed-service units (RBU) in the Veterans Health Administration (VHA), and 2) evaluate the effects of RBU and parent hospital structure on stroke rehabilitation outcomes. Two VHA-wide surveys of acute and rehabilitation services for stroke were linked with 2 y of VHA rehabilitation outcomes for stroke patients. A random effects mixed model was used to adjust for patient level covariates, control for unique site effects, and test for facility level structural effects. After adjusting for patient covariates, four structural variables were associated with length of stay or patient functional gain. These results indicate that rehabilitation structure is important to rehabilitation outcome. The individual variables identified in this study, namely, diverse multidisciplinary staff, expert physician leadership, staff participation in team care, and richer rehabilitation equipment resources, may represent the distinct aspects of a successful, comprehensive rehabilitation unit.

Incidence of stroke and season of the year: evidence of an association.

Evidence of seasonal variation in the incidence of stroke is inconsistent. This may be a likely consequence of one or more methodological shortcomings of the studies investigating this issue, including inappropriate analytic models, insufficient length of time, small sample size, and a regional (vs. national) focus. The authors' objective was to ascertain whether an association exists between season of the year and the incidence of stroke by using a methodological approach designed to overcome these limitations. The authors used a longitudinal study design involving 72,779 veterans hospitalized for stroke at any Veterans Affairs hospital nationally during the years 1986-1995. These data were analyzed by using time series methods. There was clear evidence of a seasonal occurrence for stroke in general. This seasonal effect was found for ischemic stroke, but not for hemorrhagic stroke. The peak occurrence was in mid-May. Neither the region (i.e., climate) nor the race of the patient substantially modified the seasonal trend. An explanation for this pattern remains to be determined.

A taxonomy for classification of stroke rehabilitation services.

OBJECTIVE: To develop a taxonomy for use in measuring stroke rehabilitation services. DESIGN: A cross-sectional study using facility-level survey data and extant data files. SETTING: Veterans Administration medical centers (VAMCs). VARIABLES: (1) A list of rehabilitation characteristics, including personnel, physical facilities, coordination of care, and hospital characteristics; and (2) a classification or typology of VAMCs according to the type of postacute stroke care on-site. MAIN OUTCOME MEASURES: Data sources included extant Veterans Administration (VA) computerized databases, VA central office administrative files, and 2 mailed surveys to VA rehabilitation medicine services and stroke acute care services. The rehabilitation taxonomy was derived using 2 methods that assess face and construct validity, respectively: (1) an expert panel rating, using a modified Delphi process, of the clinical importance of each of the rehabilitation characteristics; and (2) a comparison of rehabilitation characteristics across the different types of VAMCs. Variables were included in the final taxonomy if the expert panel reached consensus that the variable was clinically important, or if there were statistically significant differences in these characteristics across the different types of medical centers. RESULTS: Of 67 possible rehabilitation characteristics, a multidisciplinary expert panel reached consensus about the likely clinical importance of 21 rehabilitation characteristics, 11 of which showed statistically significant differences across different types of VAMCs. An additional 9 variables that lacked expert panel consensus differed significantly among the different medical centers. These 30 variables represent a preliminary taxonomy of key rehabilitation characteristics. Among the 20 variables that varied significantly across the different types of medical centers, 18 showed a pattern with the greatest amount of resources and organizational sophistication being found in VAMCs with rehabilitation units, followed by medical centers with geriatric units, and the least amount of resources and organizational sophistication was seen in medical centers whose postacute care services were limited to nursing home or intermediate care. CONCLUSION: Thirty rehabilitation characteristics had face validity and/or construct validity, and can be considered to represent a preliminary taxonomy for measuring stroke rehabilitation services. This study also shows that there are significant differences among hospitals in resources and organization of care deemed to be important for stroke patients.

Inappropriate drug use among community-dwelling elderly.

This study examined inappropriate drug use defined by updated criteria among respondents in the second and third in-person waves of the Duke Established Populations for Epidemiologic Studies of the Elderly. Information about sociodemographics, health status, access to health care, and drug use was determined by in-home interviews. Drug use was coded for therapeutic class and appropriateness by applying explicit criteria. Among participants, 27% of the second and 22.5% of the third in-person wave took one or more inappropriate agents. Of these drugs, the most common therapeutic classes were central nervous system and cardiovascular. Longitudinal multivariate analyses found that persons taking several prescription drugs, those having continuity of care, those who previously took inappropriate drugs, and those with many health visits were most likely (p<0.05) to use inappropriate drugs. We conclude that inappropriate drug use is common among community-dwelling elderly.

Racial variation in initial stroke severity.

BACKGROUND AND PURPOSE: Blacks experience greater morbidity and mortality from stroke than do whites. The degree to which this is due to the severity of the initial stroke is not known. The objective of this study is to determine whether there is a racial difference in initial stroke severity. METHODS: A secondary analysis of a prospective cohort of 984 veterans (29.7% black) admitted to any of 9 geographically diverse Veterans Administration Hospitals for acute stroke between April 1995 and March 1997 was performed. Initial stroke severity was ascertained by using the modified Canadian Neurological Scale (CNS) applied retrospectively to medical record data. Stroke severity, unadjusted and adjusted for covariates, was compared between black and white patients. RESULTS: Blacks had greater initial stroke severity than did whites (mean CNS score 7.96 versus 8.32, respectively; P=0.039), with a 0.5-point difference on the scale corresponding to a single-level decrement in either speech or strength of half of an extremity. This difference persisted with adjustment for other important predictors of stroke severity (P=0. 035). However, there was no significant racial difference in severity when CNS scores were collapsed into a priori clinically relevant categories. CONCLUSIONS: Compared with whites, blacks show greater severity of stroke at hospital admission. It remains uncertain whether the relatively small but significant difference at presentation fully explains the striking racial differences in morbidity and mortality from stroke.

US Department of Veterans Affairs medical care system as a resource to epidemiologists.

Epidemiologists have utilized several health care systems with large numbers of enrollees and centralized databases to achieve their research aims. Although containing many of the features that have made certain health care systems valuable to the conduct of epidemiologic research, the US Department of Veterans Affairs (VA) medical care system has not been well utilized by epidemiologists. This article will describe existing and planned features of this health care system that should be of interest to epidemiologists, including centralized databases that capture hospital discharge and outpatient clinic diagnostic data, a planned enrollment file that would contain all persons eligible for VA medical care, and the size and national dispersion of VA medical care facilities. Also, VA leadership has demonstrated an interest in the promotion of epidemiologic research by initiating several new programs, including the creation of three Epidemiologic Research and Information Centers (ERICs) to foster VA epidemiologic research, and announcing a program to support investigator-initiated epidemiologic research projects with VA funding. Epidemiologists with interests in medical problems that afflict veterans should consider partnerships with VA investigators to achieve their research aims.

Reliability and accuracy of dermatologists' clinic-based and digital image consultations.

BACKGROUND: Telemedicine technology holds great promise for dermatologic health care delivery. However, the clinical outcomes of digital image consultations (teledermatology) must be compared with traditional clinic-based consultations. OBJECTIVE: Our purpose was to assess and compare the reliability and accuracy of dermatologists' diagnoses and management recommendations for clinic-based and digital image consultations. METHODS: One hundred sixty-eight lesions found among 129 patients were independently examined by 2 clinic-based dermatologists and 3 different digital image dermatologist consultants. The reliability and accuracy of the examiners' diagnoses and the reliability of their management recommendations were compared. RESULTS: Proportion agreement among clinic-based examiners for their single most likely diagnosis was 0. 54 (95% confidence interval [CI], 0.46-0.61) and was 0.92 (95% CI, 0. 88-0.96) when ratings included differential diagnoses. Digital image consultants provided diagnoses that were comparably reliable to the clinic-based examiners. Agreement on management recommendations was variable. Digital image and clinic-based consultants displayed similar diagnostic accuracy. CONCLUSION: Digital image consultations result in reliable and accurate diagnostic outcomes when compared with traditional clinic-based consultations.

Spinal-flexibility-plus-aerobic versus aerobic-only training: effect of a randomized clinical trial on function in at-risk older adults.

BACKGROUND: As exercise is associated with favorable health outcomes, impaired older adults may benefit from specialized exercise interventions to achieve gains in function. The purpose of this study was to determine the added benefit of a spinal flexibility-plus-aerobic exercise intervention versus aerobic-only exercise on function among community-dwelling elders. METHODS: We employed a randomized clinical trial consisting of 3 months of supervised exercise followed by 6 months of home-based exercise with telephone follow-up. A total of 210 impaired males and females over age 64 enrolled in this study. Of these, 134 were randomly assigned to either spinal flexibility-plus-aerobic exercise or aerobic-only exercise, with 116 individuals completing the study. Primary outcomes obtained at baseline, after 3 months of supervised exercise, and after 6 months of home-based exercise included: axial rotation, maximal oxygen uptake (VO2max); functional reach, timed-bed-mobility; and the Physical Function Scale (PhysFunction) of the Medical Outcomes Study SF-36. RESULTS: Differences between the two interventions were minimal. Overall change scores for both groups combined indicated significant improvement for: axial rotation (p=.001), VO2max (p=.0001), and PhysFunction (p=.0016). Secondary improvements were noted for overall health (p=.0025) and reduced symptoms (p=.0008). Differences between groups were significant only for VO2max (p=.0014) at 3 months with the aerobic-only group improving twice as much in aerobic capacity as the spinal flexibility-plus-aerobic group. Repeated measures indicated both groups improved during the supervised portion of the intervention but tended to return toward baseline following the home-based portion of the trial. CONCLUSIONS: Gains in physical functioning and perceived overall health are obtained with moderate aerobic exercise. No differential improvements were noted for the spinal flexibility-plus-aerobic intervention.

Race, presenting signs and symptoms, use of carotid artery imaging, and appropriateness of carotid endarterectomy.

BACKGROUND AND PURPOSE: We sought to determine whether there are racial differences in use of carotid artery imaging after controlling for clinical factors and to ascertain racial differences in presenting signs and symptoms and overall appropriateness for carotid endarterectomy (CE). METHODS: We performed a retrospective cohort study of 803 patients older than 45 years, hospitalized between 1991 and 1994 at any of 4 Veterans Affairs Medical Centers, with a discharge diagnosis of transient ischemic attack or ischemic stroke. Clinical data were abstracted from the medical record, including presenting symptoms, diagnostic test results, and use of surgical procedures. Appropriateness for CE was determined according to RAND criteria. RESULTS: Black patients were more likely than white patients to present with stroke (78% versus 55%) but less likely to present with transient ischemic attack (22% versus 45%; P=0.001). There was no racial difference in medical comorbidity or preoperative risk. Black patients were less likely to have an imaging study of their carotid arteries (67% versus 79%; P=0.001). Race remained an independent predictor of imaging after adjustment for clinical factors (odds ratio=1.50; 95% CI, 1.06 to 2.13). Because of higher prevalence of significant carotid artery stenosis, whites were significantly more likely than blacks to be assessed as appropriate candidates for surgery with the use of RAND criteria (18% versus 4%; P=0.001). CONCLUSIONS: Use of carotid artery imaging, a critical step in determining eligibility for CE, is influenced by the patient's race after controlling for clinical presentation. Adjustment for appropriateness of CE reduces but does not eliminate the importance of race.

The validity in persons with spinal cord injury of a self-reported functional measure derived from the functional independence measure.

STUDY DESIGN: A cross-sectional, mailed survey on impairment and function using 6361 respondents to the Spinal Cord Dysfunction National Veterans Survey who reported spinal cord injury as the sole cause of their spinal cord dysfunction. OBJECTIVES: To establish the concurrent and construct validities of a Self-Reported Functional Measure appropriate for use in patients with spinal cord injuries. SUMMARY OF BACKGROUND DATA: Functional assessment is of increasing importance in clinical care, quality assurance, and national health-care planning. There is a conspicuous need for validated functional assessment measures that are rapid, reliable, and appropriate for use in the disabled population. METHODS: The correlation was examined of hours of personal assistance, number of affected limbs, amount of motor impairment, and amount of combined limb-motor impairment to Self-Reported Functional Measure response tertile (scores, 13-32, 33-45, 46-52; lower scores indicated worse function). RESULTS: There were statistically significant correlations between Self-Reported Functional Measure score and hours of personal assistance (P < 0.001), the number of affected limbs (P < 0.001), the amount of motor impairment (P < 0.001), and the amount of combined limbmotor impairment (P < 0.001). For example, 87% of people with the most limb-motor impairment (four affected limbs and no useful movement) were in the lowest Self-Reported Functional Measure tertile, compared with 3% of people in the least-affected category of limb-motor impairment. Furthermore, visual, sensory, or memory impairment did not influence the correlation between limbmotor impairment and Self-Reported Functional Measure score. CONCLUSION: The Self-Reported Functional Measure shows good concurrent and construct validities.
