Adding the items of the Functional Assessment Measure (FAM) to the Functional Independence Measure (FIM instrument) has been proposed as a method to extend the range of the FIM, particularly when assessing functional status in rehabilitation patients with brain injury, including stroke. It has been proposed that this approach is especially helpful in ameliorating ceiling effects when brain-injured patients have reached the end of their inpatient rehabilitation stay or are being seen in outpatient settings. In the present study, 376 consecutive stroke patients on a Canadian inpatient rehabilitation unit were concurrently administered the FIM and the FAM. Rasch analysis was used to evaluate how well the FAM items extended the difficulty range of the FIM for both the Motor and Cognitive domains. Within the Motor domain, only the FAM item assessing Community Access was found to be more difficult than extant FIM items, and this item showed some tendency to misfit with the other motor items. In the Cognitive domain, the only FAM item with a higher difficulty level than the FIM items was that assessing Employability. Notably, strict adherence to scoring guidelines for these two FAM items requires taking patients out into the community to evaluate their actual performances, a practice unlikely in the typical inpatient stroke rehabilitation unit. Results indicate that use of the entire FAM as an adjunct to the FIM reduces test efficiency while providing only minimal additional protection against ceiling effects.

Cocaine-associated stroke (CAS) is an important cause of disability, especially among younger adults. Improved management has increased survival but little has been discussed about rehabilitation, including medication management. Therefore, experience and therapeutic drug management are described during inpatient rehabilitation with three patients with CAS. Case 14 is a 50-year-old male with a history of hypertension who presented with right hemiparesis, aphasia and depression. He was treated with paroxetine for depression and bromocriptine for poor initiation with a good response, improving by 50 FIM points in 44 days. Case 2 is a 44 year-old female with quadriparesis, aphasia, and deficits in attention and initiation. Methylphenidate for attention deficits and bromocriptine for poor initiation was associated with an excellent functional gain (50 FIM points in 37 days). She eventually returned to work. Case 3 is a 46-year-old female with a history of hypertension who presented with right hemiparesis, aphasia and depression. Without neuropharmacologic intervention, she gained 35 FIM points during an uneventful 47 day rehabilitation stay. Acutely, cocaine can induce cerebral vasoconstriction, cerebrovascular spasm, cerebral vasculitis and intracerebral haemorrhage. Chronic use depletes and destroys dopaminergic pathways, which may be a major factor in depression, and attention and initiation deficits-all observed in these cases. Generally, rapid improvements were seen in mood and cognition in two cases where medication was used. Based on the current literature and pathophysiology of CAS, it is suggested that trials of dopaminergic agents for cognition and extremely cautious use of buproprion for depression may be warrented. Details of the above cases and the practical and theoretical issues of neuropharmacologic intervention in CAS are discussed.

The English Rivermead Mobility Index (RMI) has been proposed as a simple, valid and reliable measure in stroke rehabilitation. A German version was established and validated in two centres. In centre A 46 acute (median: 3.0 days after onset) and in centre B 151 chronic (median: 88.0 days after onset) stroke patients participated. Interrater reliability of the German RMI was tested in 12 subjects in the acute stage of stroke and was found to be statistically significant (r = 0.98, P < 0.0001). In centre A, a statistically significant correlation was found between the German RMI and the 10-m walk time at baseline (r = 0.73, P < 0.0001) and after three weeks (r = 0.92, P < 0.0001). In centre B, the German RMI correlated significantly with the motor part of the Functional Independence Measure (motor-FIM) on admission (r = 0.78, P < 0.0001) and after three weeks (r = 0.79, P < 0.0001), respectively. The change of the RMI correlated significantly with the change in 10-m walk time in acute patients (r = 0.87, P < 0.0001) and with the change in motor-FIM in chronic patients (r = 0.54, P < 0.0001). A moderate ceiling-effect was detected in the chronic study population. The German RMI appears to be a reliable, valid and responsive measure for mobility disability in acute and chronic stroke patients.

Screening patients admitted to a rehabilitation center has become important. Actually, co-existing diseases are not very often evaluated and their importance is underestimated. At our department 166 consecutive patients were enrolled. The Cumulative Illness Rating Scale (CIRS) appeared to be the most suitable for these cases. In this series, stroke patients presented with higher severity and higher comorbidity than the hip fracture patients. The hip fracture cases were older but the stroke cases had higher severity and comorbidity. Comorbidity, also, showed a significant negative correlation with FIM in the stroke patients. These data show that severe comorbid conditions influence the functional autonomy. Severity and comorbidity were correlated both in the hip fracture and stroke cases. A review of geriatric literature demonstrates lower values in patients in rehabilitation. The difference is due to our accurate selection of patients at admission, where general health conditions are considered. In conclusion, the CIRS should be used as a method for selecting patients at admission and as a prognostic index for improvement at discharge. The CIRS, however, has some inconveniences and amelioration is necessary, such as the inclusion of a double testing (admission-discharge), psychiatric disturbances and a new item for skin alone. The Severity Index was higher in women, who were older than men, whereas, comorbidity was the same. In the patients suffering from hip fracture, the age was higher in women, but dependence, severity and comorbidity did not statistically differ between the groups.

Many patients with severe stroke are capable of returning to the community after receiving rehabilitation services. The purpose of this study was to describe outcomes of patients with stroke in FIM-FRG STR1, a classification based on the Functional Independence Measure, and identify important functional tasks associated with discharge to home. FIM-FRG STR1 is one of nine subpopulations of stroke that have been identified based on motor/cognitive FIM subscale score and age. We reviewed the program evaluation data of 259 cases of stroke from 1993 to 1996. We performed a descriptive analysis of the data and a logistic regression analysis to determine which tasks measured by the FIM were associated with discharge destination, a key indicator of rehabilitation success. We found that three admission FIM variables (bladder management, toilet transfers, memory) and three discharge FIM variables (upper body dressing, bed/chair transfers, comprehension) were associated with discharge destination with up to 75% accuracy. The implications of these findings are discussed.

We describe the use of a mathematical/statistical method (i.e., Rasch analysis) to elucidate biological patterns of disability present in the functional ability of persons undergoing medical rehabilitation. Two measures chosen for illustration are the FIM Instrument for inpatients and the Body Movement and Control (BMC) measure for outpatients. In order to meet the assumptions necessary for application of linear statistics to clinical measurement studies, Rasch analysis was used to transform ordinal scales into linear measures. Another unique feature of Rasch analysis is that it allows evaluation of the difficulty of items and the abilities of persons being tested, separately, on the same metric. Also, the difficulty represented by each item may be arranged along a hierarchy from easy to hard. The hierarchies of functional ability items are dependent upon the specific patterns of disability related to underlying pathophysiology. For inpatients, initial analyses of the 18 items of the FIM Instrument demonstrated separate hierarchies for the 13 motor items and for the 5 cognition items. Subsequent analyses demonstrated five distinct patterns for the 13 motor items of: brain dysfunction, orthopedic conditions, pain conditions, ambulatory spinal cord dysfunction, and wheelchair users with spinal cord dysfunction. Two patterns were identified for cognition: stroke with right body hemiparesis and all others. For outpatients, the BMC measure of physical functioning is used to demonstrate that pathophysiologic conditions are expected to affect the hierarchial pattern of items differently. This was noted to be the case for persons with lower body dysfunction, low back pain, and neck pain/upper limb dysfunction. Based upon the item responses, sitting, reaching and standing appear to represent items most useful for discriminating between the three conditions in terms of the functional consequences. Rasch analysis, among other advantages, enables investigation of the subtle relationships among items and is a useful method to evaluate underlying biological patterns of disability. A clinician, using a map that shows the expected relationships between item scores, may observe that a particular patient matches or does not match the expected pattern. Such insights may help the clinician in monitoring the responses of the patient to treatment efforts.

We have investigated the cortical and subcortical regional cerebral blood flow (rCBF) disorders resulting from infarcts of the anterior choroidal artery (AChA), and correlations with the severity of lesions, the physical and cognitive deficits, and the functional impairment. Eighteen patients presenting with recent anterior choroidal artery infarct without any other brain injury were examined at the secondary phase post-stroke using the single photon emission computed tomography technique and 133 Xenon inhalation. The rCBF and asymmetry indexes (AI) were calculated for 12 symmetrical hemispheric areas, and the cerebellum. The AI values were compared with those of 24 control subjects. The severity of the lesions was evaluated from CT scans or MRI. The neurological status (Orgogozo scale, walking disorders, MMSE, attention impairment, aphasia) and disability (functional independance measure: FIM) were assessed for each patient at the same time period. The relationships between rCBF disorders and brain lesions, and between the results of clinical investigations and rCBF disorders and brain lesions were assessed by linear regression analyses (stepwise variable selections, p=0.05). The AI values were significantly increased in the cerebral hemispheres, and this was most severe in the internal capsule (direct effect of the lesion) and the dorsolateral hemispheric cortex (diaschisis). Individual evaluations showed that AI were significantly increased in 13 patients in at least one ROI of the cerebral hemispheres, and in 3 patients in the internal capsule. Stepwise variable selections revealed that AI were best explained by the severity of the lesions in the internal capsule and the internal temporal area. The AI of the external temporal area and the internal capsule also helped explain the clinical (physical and cognitive) deficits. Thus, AChA infarcts may have relatively large effects on the central part of the lateral and dorsal cortex of the ipsilateral hemisphere. Subcortical and cortical consequences both contribute to explain the motor and cognitive deficits and disability.

The Hooper Visual Organization Test (HVOT; Hooper, 1958) is a commonly used measure of visual perceptual function. However, serious questions have recently been raised about its construct validity (i.e., the role of object naming). This study further examined the HVOT's construct validity and began exploring its contribution to outcome prediction in stroke rehabilitation. Participants were 101 rehabilitation inpatients suffering from recent cerebrovascular accidents. Each participant was administered the HVOT as part of a comprehensive neuropsychological evaluation. Wechsler Adult Intelligence Scale-Revised (Wechsler, 1981) Object Assembly, Picture Completion, and Cognistat Naming were significantly and uniquely correlated with the HVOT and accounted for about 45% of its variance. The HVOT's value in outcome prediction was examined by correlating HVOT with admission and discharge Functional Independence Measure (FIM; Granger & Hamilton, 1990; Hamilton, Granger, Sherwin, Zielezny, & Tashman, 1987) scores. While correlating weakly with some FIM domains, when admission FIM was controlled, the relation between HVOT and discharge FIM became nonsignificant. Implications of these data for the HVOT's clinical utility are discussed.

The purpose of this pilot study was to compare differences in motor recovery between regular rehabilitation (REG), and regular rehabilitation with supported treadmill ambulation training (STAT) using the performance on a bicycle exercise test and the locomotor scale of the Functional Independence Measure (FIM-L). Twelve patients with acute strokes were randomly assigned to either REG or STAT for 2 to 3 weeks. The STAT group received daily gait training utilizing a treadmill with partial support of body weight. After intervention, the STAT group had higher oxygen consumption (11.34+/-0.88 vs 8.32+/-0.88 ml/kg/min, p=0.039), total workload (58.75+/-7.09 vs 45.42+/-7.09 watts, p=ns), and total time pedaling the bike (288.91+/-30.61 vs 211.42+/-30.61 s, p=ns) compared to the REG group. The FIM-L scores were not different for the two groups. This pilot study suggests that the STAT intervention is a promising technique for acute stroke rehabilitation, and that future studies with larger sample sizes are warranted to establish the effectiveness of this intervention.

This study aimed to develop predictive models to assist clinicians working in acute care to determine which stroke and lower limb orthopaedic patients should be discharged to nursing homes, inpatient rehabilitation, or home. The subjects were 223 patients with stroke and 125 patients with lower limb orthopaedic problems, aged 60 years and over, and the 22 acute care and rehabilitation clinicians who cared for these patients. Patient status was measured within 72 hours of discharge using the Adult FIM(SM) (Guide for the Uniform Data Set for Medical Rehabilitation, 1993) and ten additional items from either the RICFAS (Rehabilitation Institute of Chicago, 1987) or developed for this research. Four mathematical models were developed to predict discharge destination using stepwise discriminant function analysis. Using between three and seven items from the FIM(SM) alone or FIM(SM) plus additional variables, these models correctly classified between 74.9% and 80.5% of patients. In conclusion, clinicians are offered a selection of models to guide their discharge destination decisions for two large groups of patients. While these models cannot replace clinical judgement, they increase the transparency of decisions. The use of objective models to guide clinical decisions are essential, particularly given increasing pressure to justify patient access to costly rehabilitation services.
