RESUMEN

In 2002, the Institute of Medicine's recommendations emphasized diversifying the health care workforce to reduce racial and ethnic health disparities. Despite these efforts, the physical therapist profession remains predominantly White. The College of Saint Mary (CSM) Doctor of Physical Therapy program employs deliberate strategies through 2 committees, faculty search and admissions, to foster diversity in both faculty and student populations. The CSM DPT Program Faculty Search Committee, in collaboration with the CSM Human Resource Department, devised a comprehensive 3-phase recruitment process aimed at attracting qualified candidates from diverse backgrounds. Through purposeful mission-driven and equity-focused strategies, this approach has yielded a faculty body characterized by diversity, with 80% of faculty members self-identifying as belonging to historically excluded groups. Similarly, the Admissions Committee has adopted proactive measures to ensure a diverse student body. By implementing a holistic admissions process recommended by the Association of American Medical Colleges, including evaluating prerequisite courses and eliminating the Graduate Record Examination requirement, the committee has facilitated more equitable access to the program. Virtual interviews and thorough candidate assessments are conducted to mitigate potential biases in the selection process. As a result, these efforts have allowed us to maintain diverse cohorts, with 20-30% of our student body identifying as members of historically excluded groups. Impact. Developing and sustaining a physical therapist workforce that reflects the communities it serves necessitates purposeful, mission-driven, and equitable strategies. These strategies aim to broaden the diversity of both faculty and student populations. Through such initiatives, we aim to foster an inclusive environment that reflects our society's richness, enabling us to better understand society's complex needs and mitigate health disparities.

RESUMEN

OBJECTIVE: To optimize learning in physical therapist education, learners need opportunities to grow from their unique starting points. Traditional grading practices like A to F grades, zero grades, and grading on timeliness and professionalism hinder content mastery and accurate competency assessment. Grading should focus on mastery of skill and content, using summative assessments for final grades, a no-zero policy, and actionable feedback. Equitable grading supports learners from all backgrounds and identities and promotes academic success. This case study provides guidance and recommendations for implementing equitable grading practices in academic physical therapist programs. METHODS: Over a 2-year period, a doctor of physical therapy program began implementing 5 strategies to create more equitable grading practices: (1) eliminating zero grades, (2) allowing late assignment submissions without penalty, (3) using low-stakes formative assessments throughout the semester, (4) weighing end-of-course assessments more heavily than initial ones, and (5) offering a no-stakes anatomy prep course before matriculation. RESULTS: Outcomes from implementing equitable grading practices varied. Some learners felt increased stress from fewer points opportunities, while others appreciated the reduced anxiety from low-stakes assessments. Some saw multiple attempts for peers as unfair. Faculty faced higher workloads due to detailed feedback and remediation but believed it benefited learners. Median final grades improved in some courses, remained stable in others, and slightly decreased in one. Overall, the changes had minimal impact on most learners' grades but significantly improved outcomes and retention for struggling learners. CONCLUSION: This case report documents the implementation of equitable grading practices in a Doctor of Physical Therapy program, offering valuable insights and recommendations for other institutions aiming to adopt similar practices. IMPACT: Inequity in assessment widens the gap between learners entering professional programs. Equitable assessment practices level the playing field, enabling learners from diverse backgrounds and identities to succeed. Increased diversity benefits everyone, especially patients, by reducing health disparities for historically marginalized groups.

RESUMEN

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is considered a primary mechanism of imbalance among women diagnosed with breast cancer. Recent evidence, however, suggests that cancer-related fatigue (CRF) may also influence balance. Purpose: Examine the contributions of CRF and CIPN to static and dynamic balance before and after a period of fatiguing exercise. Methods: This is a secondary analysis of data examining functional differences between women with breast cancer with and without persistent CRF. Postural sway was measured during static standing and the rising phase of an instrumented sit-to-stand (ISTS) before and after exercise. Regression analyses were performed to determine how CRF and severity of CIPN predicted sway and how much variance was attributable to each. Results: Greater CRF predicted increased pre-, p=.04, and post-exertional, p=.02, static sway in the anterior-posterior plane. CRF accounted for 10.5% and 9.5% of the variance in pre- and post-exertional sway (respectively) compared to the 0.9% and 1.4% accounted for by CIPN severity which was not a significant predictor. After exercise, greater CRF predicted smaller, more conservative, anterior weight shifting during the ISTS, p=.01, and accounted for 6.6% of the variance in sway compared to 3% attributed to CIPN which was not a significant predictor. Limitations: This analysis is limited by its small and demographically homogenous sample. Conclusions: These results suggest that CRF may influence balance independent of CIPN symptoms. While CIPN remains a risk factor for imbalance in this population, CRF warrants consideration in clinical practice and research as a mechanism of postural instability.

RESUMEN

BACKGROUND AND PURPOSE: When treating older adults post-hip fracture, physical therapists routinely assess the sit-to-stand (STS) task using observational analysis. Studies have demonstrated that significant movement asymmetries in ground reaction force production of the fractured lower limb persist during STS, even though individuals may rise independently. To date, the validity of therapist judgments of lower limb force during STS has not been addressed. The purpose of this observational cohort study was to determine the accuracy of physical therapists' observational assessments of STS for detecting the involved limb and its ground reaction force contribution in older adults post-hip fracture. METHODS: Eighteen home health physical therapists assessed 10 videotapes of older adults post-hip fracture rising from sitting and judged the side of involvement and the amount of ground reaction force generated by the fractured lower limb. Each videotape was synchronized with its respective force data. A wide spectrum of asymmetry in rising was represented in the test videos. Before making these judgments, the therapists viewed a separate set of training videos and received instructions in the use of specific visual cues to assist with subsequent judgments. RESULTS AND DISCUSSION: Therapists judged the involved side correctly 74% of the time. Mean accuracy in judging ground reaction force output was 39% across all therapists. Force symmetry did not significantly influence accuracy of force judgments. Inaccurate judgments of force may limit therapeutic intensity and minimize the potential for developing motor strategies that favor force production of the involved limb. Augmenting observational analysis of STS with quantitative data could assist in optimizing restorative function. CONCLUSION: Judgments of lower limb ground reaction force output during STS based on observation alone are not valid and may need to be supplemented with quantitative data.

RESUMEN

BACKGROUND: Individuals post hip fracture decrease force on the involved limb during sit to stand tasks, creating an asymmetry in vertical ground reaction force. Joint specific differences that underlie asymmetry of the vertical ground reaction force are unknown. The purpose of this study was to compare differences in vertical ground reaction force variables and joint kinetics at the hip and knee in participants post-hip fracture, who were recently discharged from homecare physical therapy to controls. METHODS: Forty-four community-dwelling older adults, 29 who had a hip fracture and 15 elderly control participant's completed the sit to stand task on an instrumented chair with 3 force plates. T-tests were used to compare clinical tests (Berg Balance Scale, activity balance confidence and gait speed, isokinetic knee strength) and vertical ground reaction force variables. Two-way analyses of variance compared vertical ground reaction force variables and kinetics at the hip and knee between hip fracture and elderly control groups. Pearson correlation coefficients were used to determine correlations between clinical and vertical ground reaction force variables. FINDINGS: Vertical ground reaction force variables were significantly lower on the involved side for the hip fracture group compared to the uninvolved side and controls. Lower involved side hip and knee moments and power contributed to lower involved side vertical ground reaction force. Vertical ground reaction force variables and strength had moderate to high correlations with clinical measures. INTERPRETATION: Uninvolved side knee moments and powers were the largest contributors to asymmetrical vertical ground reaction force in participants post-hip fracture. The association of vertical ground reaction force variables and clinical measures of function suggesting reducing vertical ground reaction force asymmetry may contribute to higher levels of function post-hip fracture. Functional and strength training should target the involved knee to reduce vertical ground reaction force asymmetry.

RESUMEN

Cancer patients treated with cytotoxic chemotherapy experience fatigue and changes in body composition that can impact physical functioning and quality of life during and after treatment. Interleukin-6 (IL-6) is associated with fatigue in cancer survivors and plays an important role in the regulation of body composition. The purpose of the present study was to determine the specific role of IL-6 in cyclophosphamide-doxorubicin-5-fluorouracil (CAF)-induced changes in fatigue, food intake, and body composition using mice lacking IL-6. Female wild-type (WT) and IL-6 (-/-) mice were injected with four cycles of CAF or normal saline (NS) administered at 21-day intervals. Daily voluntary wheel-running activity (VWRA), used as a proxy for fatigue, and food intake were monitored daily up to 21 days after the fourth dose. Dual-energy X-ray absorptiometry (DEXA) was used to assess treatment-related changes in lean body mass (LBM), fat mass (FM), and bone mineral content (BMC). Patterns of change in fatigue and food intake did not differ between CAF-treated WT and IL-6 (-/-) mice. However, a Genotype × Drug interaction was observed for LBM (p = 0.047) and FM (p = 0.035) but not BMC (p = .569). Whereas WT mice lost LBM and FM during CAF treatment, IL-6-deficient mice did not. Treatment-related decreases in levels of the anabolic hormone insulin-like growth factor-1 (IGF-1) may contribute to LBM and FM loss since CAF decreased IGF-1 levels in an IL-6-dependent manner. These findings implicate IL-6 and possibly IGF-1 in the regulation of body composition in breast cancer patients exposed to cytotoxic chemotherapy.

RESUMEN

STUDY DESIGN: Controlled laboratory study using a cross-sectional design. OBJECTIVES: To compare lower extremity force applications during a sit-to-stand (STS) task with and without upper extremity assistance in older individuals post-hip fracture to those of age-matched controls. BACKGROUND: A recent study documented the dependence on upper extremity assistance and the uninvolved lower limb during an STS task in individuals post-hip fracture. This study extends this work by examining the effect of upper extremity assistance on symmetry of lower extremity force applications. METHODS: Twenty-eight community-dwelling elderly subjects, 14 who had recovered from a hip fracture and 14 controls, participated in the study. All participants were independent ambulators. Four force plates were used to determine lower extremity force applications during an STS task with and without upper extremity assistance. The summed vertical ground reaction forces (vGRFs) of both limbs were used to determine STS phases (preparation/rising). The lower extremity force applications were assessed statistically using analysis of variance models. RESULTS: During the preparation phase, side-to-side symmetry of the rate of force development was significantly lower for the hip fracture group for both STS tasks (P<.001). During the rising phase, the vGRF impulse of the involved limb was significantly lower for the hip fracture group for both STS tasks (P = .045). The vGRF impulse for the uninvolved limb was significantly increased when participants with hip fracture did not use upper extremity assistance compared to elderly controls (P = .002). This resulted in a significantly lower vGRF symmetry for the hip fracture group during both STS tasks (P<.001). CONCLUSION: Participants with hip fracture who were discharged from rehabilitative care demonstrated decreased side-to-side symmetry of lower extremity loading during an STS task, irrespective of whether upper extremity assistance was provided. These findings suggest that learned motor control strategies may influence movement patterns post-hip fracture.

RESUMEN

BACKGROUND: A Sit to Stand task following a hip fracture may be achieved through compensations (e.g. bilateral arms and uninvolved lower extremity), not restoration of movement strategies of the involved lower extremity. The primary purpose was to compare upper and lower extremity movement strategies using the vertical ground reaction force during a Sit to Stand task in participants recovering from a hip fracture to control participants. The secondary purpose was to evaluate the correlation between vertical ground reaction force variables and validated functional measures. METHODS: Twenty eight community dwelling older adults, 14 who had a hip fracture and 14 control participants completed the Sit to Stand task on an instrumented chair designed to measure vertical ground reaction force, performance based tests (Timed up and go, Berg Balance Scale and Gait Speed) and a self report Lower Extremity Measure. A MANOVA was used to compare functional scales and vertical ground reaction force variables between groups. Bivariate correlations were assessed using Pearson Product Moment correlations. FINDINGS: The vertical ground reaction force variables showed significantly higher bilateral arm force, higher uninvolved side peak force and asymmetry between the involved and uninvolved sides for the participants recovering from a hip fracture (Wilks' Lambda=3.16, P=0.019). Significant correlations existed between the vertical ground reaction force variables and validated functional measures. INTERPRETATION: Participants recovering from a hip fracture compensated using their arms and the uninvolved side to perform a Sit to Stand. Lower extremity movement strategies captured during a Sit to Stand task were correlated to scales used to assess function, balance and falls risk.
