Competent in any context: An integrated model of interprofessional education.

While most graduate health professions programs in the United States have accepted the Interprofessional Education Collaborative's core competencies for collaborative practice, there is no consistent way to integrate the competencies into courses of study already crowded with uniprofessional competencies. A potential negative effect of treating interprofessional education as an add-on is that learners will not engage deeply with the competencies required to work effectively in health care teams. To design an integrated model, one institution adopted a theory from the management literature that frames professional competence as a way of being, not simply a body of knowledge to master. Viewing competence as a way of being ensures that learners can act collaboratively in any context. The model, called IMPACT Practice, provides multiple settings where learners can practice the competencies and make connections to their uniprofessional studies. By embedding the interprofessional competencies into all programs of study, learners come to see collaboration as a core element of what it means to be an effective health professional.

Applying concepts of responsiveness to patient management in neurologic physical therapy.

Determining whether real change has taken place as a result of treatment and whether that change constitutes important change are challenges central to evidence-based physical therapist practice. Recently, the literature reporting these values for clinical measures has expanded considerably. In this article, we discuss some of the indices for identifying real change and important change, and how physical therapists can use these indices to enhance the interpretability of change scores derived from clinical measures. Specifically, we define and discuss the uses of the minimal detectable change and the minimal clinically important difference. We provide suggestions for how these indices can be used to make change scores more meaningful to therapists, patients, their caregivers, and third-party payers. Accurate interpretation and application of these indices are crucial to informed patient management and clinical decision making. We also present some of the limitations confronted as we try to apply these values across various patient diagnostic groups and across the spectrum of initial level of impairment. Finally, recommendations are made for directions for future research in this important area of outcomes research and how clinicians can contribute to these efforts.

The accuracy of individual Berg Balance Scale items compared with the total Berg score for classifying people with chronic stroke according to fall history.

BACKGROUND AND PURPOSE: To determine whether individual Berg Balance Scale (BBS) items or a group of items would have greater accuracy than the total BBS in classifying community-dwelling people with stroke with a history of multiple falls. METHODS: The subjects were 44 community-dwelling individuals with chronic stroke; 34 had one or no falls in the past six months, and 10 had multiple falls. Each BBS item was dichotomized at three points along the scoring scale of 0-4: between scores of 1 and 2, 2 and 3, and 3 and 4. Sensitivity (Sn), specificity (Sp), and positive (+LR) and negative (-LR) likelihood ratios were calculated for all items for each scoring dichotomy based on their accuracy in classifying subjects with a history of multiple falls. These findings were compared with the total BBS score where the cutoff score was derived from receiver operating characteristic curve analysis. RESULTS: Dichotomized point 3-4 for items B11 (turning 360 degrees), B12 (alternate foot on stool), B13 (tandem stance), and B14 (standing on one leg) all revealed Sn greater than 60%. B14 had the best Sn and Sp (0.90 and 0.50). Combining B11, B12, or B13 with B14 did not improve Sn. Total BBS receiver operating characteristic curve revealed a cutoff score of 52 (Sn = 90% and Sp = 41%). CONCLUSION: Using selected items from the BBS may be more time efficient and accurate than the total BBS score for classifying people with chronic stroke living in the community with a history of multiple falls. Prospective study is needed to validate these findings relative to fall prediction.

Using the International Classification of Functioning, Disability and Health as a framework to examine the association between falls and clinical assessment tools in people with stroke.

BACKGROUND: Falls in people with stroke are extremely common and present a significant health risk to this population. Development of fall screening tools is an essential component of a comprehensive fall reduction plan. OBJECTIVE: The purpose of this study was to examine the accuracy of clinical measures representing various domains of the International Classification of Functioning, Disability and Health (ICF) relative to their ability to identify individuals with a history of multiple falls. DESIGN: A case series study design was used. SETTING: The study was conducted in a community setting. PARTICIPANTS: Twenty-seven people with stroke participated in the study. MEASUREMENTS: Clinical assessment tools included the lower-extremity subscale of the Fugl-Meyer Assessment of Sensorimotor Impairment (FMLE) and Five-Times-Sit-to-Stand Test (STS) representing the body function domain, the Berg Balance Scale (BBS) representing the activity domain, the Activities-specific Balance Confidence (ABC) Scale as a measure of personal factors, and the physical function subscale of the Stroke Impact Scale (SIS-16) as a broad measure of physical function. We used receiver operating characteristic (ROC) curves to generate cutoff scores, sensitivities, specificities, and likelihood ratios (LRs) relative to a history of multiple falls. RESULTS: The FMLE and the STS showed a weak association with fall history. The BBS demonstrated fair accuracy in identifying people with multiple falls, with a cutoff score of 49 and a positive LR of 2.80. The ABC Scale and the SIS-16 were most effective, with cutoff scores of 81.1 and 61.7, respectively, positive LRs of 3.60 and 7.00, respectively, and negative LRs of 0.00 and 0.25, respectively. LIMITATIONS: A limitation of the study was the small sample size. CONCLUSION: The findings suggest that the ICF is a useful framework for selecting clinical measures relative to fall history and support the need for prospective study of tools in more-complex domains of the ICF for their accuracy for fall prediction in people with stroke.

Advantage of limb salvage over amputation for proximal lower extremity tumors.

UNLABELLED: Although function after lower extremity amputation and limb salvage has been compared, no study has assessed individual functional variables by surgical level. Our aim was to determine whether risks of long-term psychologic and physical limitations were associated with amputation or limb salvage at four levels: below-knee, above-knee, hip, and pelvis. We included 408 patients with sarcomas and postoperative followup of 2 years or greater who had completed a quality-of-life self-report questionnaire. The mean length of followup was 8.91 +/- 5.15 years (range, 2-27 years). Relative risk analysis was done on 12 dichotomous general health, psychologic, and physical function variables. At the below-knee level, outcomes were similar after both procedures. At the above-knee level, amputation was associated with increased risk of limp (RR = 1.6), walking aid use (RR = 2.1), anxiety (RR = 2.4), and inability to drive (RR = 3), and decreased risk of muscle weakness (RR = 0.57). At the hip and pelvic levels, outcomes were descriptively compared because of the small number of amputations. At these higher levels, limitations were more common after amputation. The difference in results between the below-knee and above-knee levels supports the importance of distinguishing surgical levels. Limb salvage offers a functional advantage at proximal tumor locations. LEVEL OF EVIDENCE: Therapeutic study, Level III (retrospective, comparative study). See the Guidelines for Authors for a complete description of levels of evidence.

Determinants of balance confidence in community-dwelling elderly people.

BACKGROUND AND PURPOSE: The fear of falling can have detrimental effects on physical function in the elderly population, but the relationship between a persons' confidence in the ability to maintain balance and actual balance ability and functional mobility is not known. The extent to which balance confidence can be explained by balance performance, functional mobility, and sociodemographic, psychosocial, and health-related factors was the focus of this study. SUBJECTS: The subjects were 50 community-dwelling elderly people, aged 65 to 95 years (mean=81.7, SD=6.7). METHODS: Balance was measured using the Berg Balance Scale. Functional mobility was measured using the Timed Up Go Test. The Activities-specific Balance Scale was used to assess balance confidence. Data were analyzed using Pearson correlation, multiple regression analysis, and t tests. RESULTS: Fifty-seven percent of the variance in balance confidence could be explained by balance performance. Functional mobility and subject characteristics examined in this study did not contribute to balance confidence. DISCUSSION AND CONCLUSION: Balance performance alone is a strong determinant of balance confidence in community-dwelling elderly people.

Construct validation of a model for professional behavior in physical therapist students.

BACKGROUND AND PURPOSE: For physical therapist educators, professional behavior has been difficult to define. The purpose of this study was to test the construct validity of a model of professional behavior that was previously established through consensus and reported in the literature. SUBJECTS AND METHODS: One hundred eighty-three students from 2 professional programs participated in the study. Using a self-administered questionnaire, students assessed how frequently they performed 152 behaviors on a 7-point Likert scale. Data were analyzed using principal components factor analysis. A Cronbach alpha was used to demonstrate internal consistency of items within each factor. Factor scores were submitted as dependent variables in analyses of variance to examine the differences in abilities according to amount of clinical education completed. RESULTS: The analysis identified 7 factors that explained 52% of the variance. These factors were labeled Professionalism, Critical Thinking, Professional Development, Communication Management, Personal Balance, Interpersonal Skills, and Working Relationships. Cronbach alphas ranged from.81 to.95. Behaviors increased in frequency in 4 of the 7 areas identified according to the level of students' progress in the educational program. DISCUSSION AND CONCLUSION: The 7 factors corresponded fairly well to the 10 generic abilities previously identified. Although some behaviors may increase in frequency over the course of students' educational experience, others may be displayed at admission.

Is base of support greater in unsteady gait?

BACKGROUND AND PURPOSE: We investigated dynamic interfoot distance (IFD) throughout the gait cycle in people with unsteady gait caused by vestibulopathy and in people without known neuromuscular pathology. We expected that the subjects with unsteady gait would use a greater IFD than subjects without neuromuscular pathology and that this IFD would be correlated with other measures of locomotor stability. SUBJECTS AND METHODS: Simultaneous whole-body (11-segment) dynamic kinematic data were collected from 22 subjects with vestibulopathy and 22 subjects without known neuromuscular pathology who were matched for age, height, weight, and body mass index. Two trials each of the participants' gait at preferred speed and paced gait at 120 steps/min were analyzed with a repeated-measures design with multiple dependent variables. Quantitative data were analyzed descriptively and with inferential statistics. RESULTS: Interfoot distance at preferred gait speed did not differentiate unsteady subjects with vestibulopathy from the comparison subjects. Paced gait IFD total range and IFD in single-limb support differed between groups, but IFD at heel-strike did not. However, IFD at heel-strike, the traditional measure of "base-of-support width," was correlated with measurements of whole-body center-of-gravity stability (r=.32-.55). DISCUSSION AND CONCLUSION: Gait at preferred speed permitted the unsteady subjects and the comparison subjects to select similar IFD values, but at the cost of slower gait in the unsteady subjects. When required to walk at a "normal" pace of 120 steps/min, subjects with vestibulopathy increased their IFD. These data suggest that wide-based gait alone cannot differentiate between subjects with and without balance impairments. Base of support and other whole-body kinematic variables are mechanical compensations of vestibulopathic instability. Further studies are needed to determine whether development of active control of these whole-body control variables can occur after vestibular rehabilitation.
