Assessment of Exercise Capacity in Home Healthcare: Differences in Three Self-Paced Tests.

Submaximal functional tests of endurance are ubiquitous in clinical practice. This investigation compared cardiovascular responses, perceived exertion, and performance measures following the completion of three self-paced, 2-minute, functional tests of endurance. A pilot prospective, observational, cross-sectional design with 16 community-dwelling older participants compared heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), rating of perceived exertion (RPE), and performance measures following the completion of three randomly allocated self-paced activities. The three activities included 2 minutes of stepping in standing (2MSTD), 2 minutes of seated stepping (2MSIT), and a 2-minute walk test (2MWT). A within-subjects repeated measures ANOVA analyzed differences in change scores for cardiovascular and RPE responses. Pearson's correlations assessed associations in performance measures between the three tests. Standing stepping compared to seated stepping produced statistically higher change scores in HR, SBP, DBP, and RPE (p < .05). Further, 2MSTD revealed statistically higher SBP and RPE scores compared to 2MWT (p < .05). Large and moderate correlations were observed between number of steps completed in sitting and standing (r = 0.83, p < .01) and between standing steps and distance walked (r = 0.56, p = .02), respectively. This pilot investigation informs home care physical therapists that 2 minutes of self-paced stepping in standing produced the greatest change scores in all cardiovascular and perceived exertion responses. No significant differences were noted in HR between self-paced walking and standing stepping, and between standing and seated stepping. For patients unable to walk or step in standing, self-paced seated stepping may be a viable alternative.

Differences in Rate of Perceived Exertion and Workload Intensity in Males and Females during Submaximal Arm and Leg Ergometry.

Purpose: Arm ergometry (AE) is necessitated for individuals unable to perform leg ergometry (LE) exercise. This study explored gender differences in RPE and workload (WL) during AE and LE at submaximal target heart rates (THR). Methods: 35 healthy college-aged individuals were randomly allocated to begin exercise on either AE or LE. Participants exercised on both modes with increasing WL to achieve submaximal THRs of 110, 120, 130, 140 and 150 beats per minute (bpm). Factorial ANOVAs tested for differences in RPE and WL. Results: No significant differences were found in RPE between genders, as well as between arm and leg exercise (p > 0.001). For WL, a significant main effect was found for mode with LE greater than AE (p < 0.001), and gender, with males greater than females (p < 0.001). A significant interaction effect was also found for HR and mode, with a greater increase in WL during LE compared to AE in both genders (p = 0.001). Conclusions: Exercise specialists typically prescribe exercise based on a chosen THR. The results of this study provide meaningful data on mean RPE and WL responses that a given THR elicits for ergometry. The finding of no differences in RPE between AE and LE informs the clinician that at any given submaximal THR, similar RPE scores can be expected during AE and LE. Further research is warranted to investigate differences in wider populations.

A Knowledge Translation Framework for Optimizing Physical Therapy in Patients With Heart Failure.

The American Physical Therapy Association has supported the development of clinical practice guidelines to promote and support evidence-based practice and reduce unwarranted practice variation. Essential to the success of this effort is the generation of knowledge translation, a concept that emphasizes the translation of global knowledge to an application that can be effectively integrated into clinical practice. The Physical Therapy Clinical Practice Guideline for the Management of Individuals with Heart Failure published in the Physical Therapy Journal in January 2020 provides a broad base of knowledge related to evidence-based treatment interventions for patients with heart failure. However, the application and integration of this knowledge in clinical practice need further elucidation. Therefore, this perspective paper aims to serve as a complementary knowledge translation resource to the recently published practice guideline to maximize the utilization of contemporary evidence in clinical practice. This resource provides the physical therapist with practical guidance in the management of patients with heart failure by placing research findings in the context of other knowledge and practice norms that can be applied at the point of care and across the continuum of care. We propose a novel ABCDE (assessment, behavior modification, cardiorespiratory fitness, dosage, and education) practical framework. This clinical paradigm is grounded in ongoing physical therapist assessment throughout the episode of care, along with behavior modification, assessment of cardiorespiratory fitness, appropriate selection and dosing of interventions, and patient education. Examples highlighting the use of this model in patients with heart failure across the continuum of care are provided for application in clinical care.

Physical Therapist Clinical Practice Guideline for the Management of Individuals With Heart Failure.

The American Physical Therapy Association (APTA), in conjunction with the Cardiovascular and Pulmonary Section of APTA, have commissioned the development of this clinical practice guideline to assist physical therapists in their clinical decision making when managing patients with heart failure. Physical therapists treat patients with varying degrees of impairments and limitations in activity and participation associated with heart failure pathology across the continuum of care. This document will guide physical therapist practice in the examination and treatment of patients with a known diagnosis of heart failure. The development of this clinical practice guideline followed a structured process and resulted in 9 key action statements to guide physical therapist practice. The level and quality of available evidence were graded based on specific criteria to determine the strength of each action statement. Clinical algorithms were developed to guide the physical therapist in appropriate clinical decision making. Physical therapists are encouraged to work collaboratively with other members of the health care team in implementing these action statements to improve the activity, participation, and quality of life in individuals with heart failure and reduce the incidence of heart failure-related re-admissions.
