Purpose
The purpose of this review was to assess the quality of evidence on inspiratory muscle training (IMT) in patients with heart failure and to provide an overview on subject selection, training protocols, and outcome achieved with IMT.Methods
Literature search was first performed via the PubMed database, and additional references were identified from the Scopus citation index. Articles of the review type and of clinical trials published in English were included. Quality of the articles was assessed using Sackett''s levels of evidence and rigor of methodology was assessed using PEDro (Physiotherapy Evidence Database) criteria for randomized controlled trials and the Downs & Black tool for cohort studies.Results
Twelve articles of clinical trials were included. Typical training protocols involved daily training with intensity greater than 30% of maximal inspiratory pressure (PImax), duration of 20 to 30 minutes (continuous or incremental) and using a pressure threshold muscle trainer. The effect sizes of PImax, walk test distance, and dyspnea were moderate to large across these studies. Effects on quality of life scores were inconsistent.Conclusion
Inspiratory muscle training is beneficial for improving respiratory muscle strength, functional capacity, and dyspnea in patients with stable heart failure and respiratory muscle weakness.Key Words: inspiratory muscle training, heart failure, maximal inspiratory pressure 相似文献3.

Purpose
Recently there has been increased interest in early mobilization of critically ill patients. Proposed benefits include improvements in respiratory function, muscle wasting, intensive care unit (ICU), and hospital length of stay. We studied the frequency of early mobilization in our intensive care unit in order to identify barriers to early mobilization.Methods
A 4-week prospective audit of 106 patients admitted to a mixed medical-surgical tertiary ICU (mean age 60 ± 20 years, mean APACHE II score 14.7 ± 7.8) was performed. Outcome measures included number of patient days mobilized, type of mobilization, adverse events, and reasons for inability to mobilize.Results
Patients were mobilized on 176 (54%) of 327 patient days. Adverse events occurred in 2 of 176 mobilization episodes (1.1%). In 71 (47%) of the 151 patient days where mobilization did not occur, potentially avoidable factors were identified, including vascular access devices sited in the femoral region, timing of procedures and agitation or reduced level of consciousness.Conclusions
Critically ill patients can be safely mobilized for much of their ICU stay. Interventions that may allow more patients to mobilize include: changing the site of vascular catheters, careful scheduling of procedures, and improved sedation management.Key Words: intensive care units, mobility, physical therapy 相似文献4.

Purpose
The aim of this study was to investigate the effects of mobilization on respiratory and hemodynamic parameters in critically ill obese patients.Methods
Critically ill obese patients (n = 31) were included in this retrospective study. Data were collected from patients’ files and physiotherapy records of mobilization sessions. Heart rate (HR), systolic/diastolic/mean blood pressure, respiratory rate (RR), and percutaneous oxygen saturation (SpO2) were recorded. Cardiorespiratory parameters were collected just prior to the mobilization, just after the completion of the mobilization and after 5 minutes recovery period. Respiratory reserve was calculated before and after the mobilization.Results
A total of 37 mobilization sessions in 31 obese patients (mean age: 63.3 years, mean BMI: 32.2 kg/m2) who received physiotherapy were analyzed. Respiratory rate increased significantly after the completion of the mobilization compared to initial values (p < 0.05). SpO2 significantly increased (p < 0.05) and all other parameters remained similar (p > 0.05) compared to initial values after the recovery period. Mobilization resulted in a significant increase in respiratory reserve (p < 0.05).Conclusion
Early mobilization in intensive care unit promotes respiratory reserve in obese patients. We found that mobilization can be performed safely in critically ill obese patients if cardiorespiratory parameters are continuously monitored.Key Words: obesity, mobilization, critically ill patients, physiotherapy 相似文献5.

Introduction
There are limited data describing mobility interventions provided to patients with femoral catheters. The purpose of this study was to examine the incidence of femoral catheter related adverse effects during physical therapy (PT) sessions in a cardiovascular intensive care unit (ICU).Methods
This was a prospective, observational study and included patients with at least one femoral catheter. Data were collected after each PT session.Results
There were 77 subjects with a total of 92 femoral catheters (50 arterial, 15 central venous, and 27 dialysis) treated. A total of 210 separate PT sessions occurred with 630 mobility activities including sitting on side of bed, standing at the bedside, transfers to stretcher chair or regular chair, and walking. There were no catheter related mechanical or thrombotic complications during any of the PT sessions.Conclusions
Physical therapy sessions, including standing and walking were feasible and safe in cardiovascular ICU patients with femoral catheters who met the criteria for mobility interventions. The results from this study support the hypothesis that early mobilization in patients with femoral catheters is important to minimize functional decline and provide evidence that the presence of femoral catheters alone should not be a reason to limit progressive mobility interventions.Key Words: physical therapy, ICU, early mobilization, femoral catheter 相似文献6.

Purpose
Reduced cardiovascular fitness post-stroke may negatively impact recovery. There is little information regarding exercise testing performance and cardiorespiratory response to an aerobic exercise intervention in subacute stroke. The purpose of this study was to examine cardiorespiratory response in subacute stroke after an 8-week aerobic exercise intervention using a total body recumbent stepper (TBRS).Methods
Nine individuals with mean age 61.2 (SD 4.7) years and mean 66.7 (SD 41.5) days post-stroke completed the exercise intervention. Participants had a mean Fugl-Meyer score of 100.3 (SD 29.3). Outcome measures were obtained at baseline and postintervention. A peak exercise test using a TBRS assessed oxygen consumption, heart rate, and minute ventilation. Participants completed an 8-week exercise intervention on a recumbent stepper 3 times per week at a prescribed heart rate intensity.Results
Submaximal VO2 was significantly lower from baseline to postintervention with a main effect of Study Visit (F1,8 = 8.5, p = 0.02). Heart rate was not significantly different pre- to postintervention. Minute ventilation exhibited no main effect of Study Visit or Test Minute.Conclusion
Moderate-high intensity aerobic exercise in subacute stroke appears to be beneficial for improving cardiovascular outcomes during submaximal performance of an exercise test.Key Words: oxygen uptake, cerebrovascular accident, cardiovascular fitness, submaximal exercise 相似文献8.

Purpose
Following a cardiac event patients are at risk for deficits in mobility and function. However, measures of physical performance are not commonly used and have not been extensively studied in patients enrolled in cardiac rehabilitation. The purpose of this study was to determine the reliability and the minimal detectable change (MDC) of gait speed, 5 times sit to stand (5 STS) and hand grip strength for individuals enrolled in cardiac rehabilitation.Methods
Forty-nine individuals enrolled in phase II or III cardiac rehabilitation participated in the study. Gait speed, 5 STS, and hand grip strength were measured over two sessions held on the same day. Intraclass correlation coefficient was used to determine reliability and MDC95 was calculated to measure responsiveness.Results
All 3 measures showed high reliability (ICC for gait speed = 0.96, 5 STS = 0.87, right hand grip strength = 0.97, left hand grip strength = 0.97). The MDC95 for gait speed was 0.16 meters/second, 3.12 seconds for 5 STS, 5.2 kilograms for right and 5.1 kilograms for left hand grip strength.Conclusion
Gait speed, 5 STS, and hand grip strength are reliable and responsive measures for patients in cardiac rehabilitation. Findings support their use in clinical practice and future cardiac rehabilitation studies.Key Words: cardiac rehabilitation, gait speed, sit to stand 相似文献11.

Purpose
The purpose of this study was to compare an Exercise Training Group (EX) with an Attention-Control Group (AT-C) to more specifically assess the impact of exercise training on individuals with heart failure (HF).Methods
Forty-two individuals with HF were randomized to AT-C or EX that met with the same frequency and format of investigator interaction. Baseline, 12- and 24-week measurements of B-type naturetic peptide (BNP), 6-minute walk test (6-MWT), and the Kansas City Cardiomyopathy Questionnaire (KCCQ) were obtained.Results
BNP tended to increase in the AT-C while remaining stable in the EX over time. A clinically significant increase in 6-MWT was demonstrated by the EX but not the AT-C. The EX achieved a clinically significant change on the KCCQ at 12 weeks, with further improvement by 24 weeks, while the AT-C demonstrated a clinically significant change at 24 weeks.Conclusions
Attention alone was inadequate to positively impact BNP levels or 6-MWT distances, but did have a positive impact on quality of life after 24 weeks. Although exercise offers enhanced benefits, individuals with HF unable to participate in an exercise program may still gain quality of life benefits from participation in a peer-support group that discusses topics pertinent to HF.Key Words: heart failure, attention, exercise 相似文献13.

Purpose
Performing exercise tests in patients with an implantable cardioverter defibrillator (ICD) presents specific challenges because of susceptibility to ventricular arrhythmias during maximal levels of exertion. The purpose of this paper is to outline the exercise testing protocol from the Anti-Arrhythmic Effects of Exercise after an ICD trial and to report baseline test results and safety outcomes using the protocol.Methods and Results
Maximal cardiopulmonary exercise testing was performed to assess levels of physical fitness as part of a randomized trial of walking exercise in patients with ICDs. Subjects were randomized after baseline testing to aerobic exercise plus usual care or usual care alone. A modified Balke treadmill exercise test was used and specific ICD programming procedures were implemented to avoid unnecessary shocks, which included programming off ventricular tachycardia (VT) therapies during testing. To date, 161 baseline tests have been performed. One ventricular fibrillation (VF) cardiac arrest occurred following completion of an exercise test and three tests were stopped by the investigators due to nonsustained ventricular tachycardia. Eleven subjects were not able to achieve maximum exercise, defined as reaching an anaerobic threshold (AT) at baseline testing. There have been no deaths as a result of exercise testing.Conclusions
Symptom-limited maximal exercise testing can be performed safely and effectively in patients with ICDs for both primary and secondary prevention indications. Specific strategies for ICD programming and preparation for treating ventricular arrhythmias needs to be in place before exercise testing is performed.Key Words: implanted cardioverter defibrillator, exercise testing, treadmill protocol 相似文献14.

Purpose
To determine if 30 minutes of Nintendo Wii Sports boxing provides cardiorespiratory benefits and contributes to the daily exercise recommendations for healthy young adults.Methods
Twenty healthy 23- to 27-year-olds participated in two sessions to measure maximum heart rate (HRmax) via a treadmill test and heart rate (HR) response to 30 minutes of Wii Sports boxing. Heart rate in beats per minute (bpm) was measured continuously, and exercise intensity during each minute of play was stratified as a percentage of HRmax. Mixed designs analysis of variance (ANOVA) and Pearson product moment correlations were used to analyze the data.Results
Mean (SD) HR response to boxing was 143 (15) bpm or 77.5% (10.0%) of HRmax. The mean HR response for experienced participants was significantly lower than inexperienced participants, P = .007. The ANOVA revealed a significant interaction between experience and time spent at various intensities, P = .009. Experienced participants spent more time in light to vigorous intensities, inexperienced participants in moderate to very hard intensities. Fitness was not correlated with mean HR response to boxing, P = .49.Conclusion
Thirty minutes of Nintendo Wii Sports boxing provides a moderate to vigorous aerobic response in healthy young adults and can contribute to daily recommendations for physical activity.Key Words: exergaming, cardiorespiratory training, active video games 相似文献15.

Purpose
The study purpose was to assess perceptions of physical therapists (PTs) regarding the role of physical therapy in cardiovascular disease (CVD) prevention.Methods
A 25-item survey, validated by expert cardiovascular/pulmonary (CVP) PTs, was sent electronically to 2,673 PTs. Each item represented an element of clinical practice behavior: education of CVD/risk factors (EDCVD), administration of primary CVD prevention (PRECVD), identifying underlying CVD/risk factors (IDCVD), monitoring CV status in patients with CVD (MONCVD). Responses were assigned numeric values (strongly agree = 5 to strongly disagree = 1), and mean element scores were analyzed.Results
Most of the 516 respondents were APTA Section members (34% CVP Section, 42% other Section membership) and worked in academia (53%). Items showing a high (> 95%) level of agreement included patient education of smoking (97%) and monitoring exercise intensity (99%), assessing exercise benefits (99%), clinically identifying obesity (97%) and hypertension (97%), and monitoring CV response to exercise (99%). Items failing to reach 80% overall agreement were patient education of CVD medications (79%) and blood chemistry (72%), and assessing CVD family history (75%), patient BMI (60%), and body composition (33%). Identifying underlying CVD (77.2%) was the only practice behavior failing to reach 80% agreement. Outpatient PTs agreed significantly less to all elements vs. academics, and to IDCVD vs. all PTs except home health.Conclusions
Physical therapists support most CVD prevention behaviors, but not given elements of patient education and identifying underlying CVD/risk factors.Key Words: cardiovascular disease, primary disease prevention, secondary disease prevention 相似文献16.

Purpose
Physical therapists (PTs) have a unique opportunity to intervene in the area of health promotion. However, no instrument has been validated to measure PTs’ views on health promotion in physical therapy practice. The purpose of this study was to evaluate the content validity and test-retest reliability of a health promotion survey designed for PTs.Methods
An expert panel of PTs assessed the content validity of “The Role of Health Promotion in Physical Therapy Survey” and provided suggestions for revision. Item content validity was assessed using the content validity ratio (CVR) as well as the modified kappa statistic. Therapists then participated in the test-retest reliability assessment of the revised health promotion survey, which was assessed using a weighted kappa statistic.Results
Based on feedback from the expert panelists, significant revisions were made to the original survey. The expert panel reached at least a majority consensus agreement for all items in the revised survey and the survey-CVR improved from 0.44 to 0.66. Only one item on the revised survey had substantial test-retest agreement, with 55% of the items having moderate agreement and 43% poor agreement.Conclusions
All items on the revised health promotion survey demonstrated at least fair validity, but few items had reasonable test-retest reliability. Further modifications should be made to strengthen the validity and improve the reliability of this survey.Key Words: health promotion, physical therapy, validity, reliability 相似文献17.

Purpose
Large therapeutic rolls (LTR) and balls are popular rehabilitation tools and have also been advertised as cardiovascular training devices. The aim of this study was to determine if individuals of varying fitness levels would reach aerobic training levels by evidence-based standards as described in American College of Sports Medicine (ACSM) publications.Methods
Fourteen volunteers performed a maximal exercise test and on subsequent days, two submaximal exercise tests on the LTR (LTR-A and -B). LTR-A consisted of four 5-minute stages of exercise at progressive intensity levels. LTR-B included 20 minutes of continuous exercise. Oxygen consumption (VO2) and heart rate (HR) during exercise on the LTR were compared with ACSM recommended standards.Results
The average (range) peak intensity achieved during LTR-A was 66.8% (51.7-82.7%) of maximal VO2 reserve (VO2R) and 82.9% (70.7%-91.2%) of maximal heart rate (HRmax). During LTR-B, HR and VO2 of all participants was maintained at moderate exercise intensity and averaged 56% of VO2R and 78% of HRmax during the 20 minute exercise period.Conclusions
These findings suggest that individuals with a wide range of aerobic fitness are able to reach and maintain aerobic training levels with appropriate exercise on a large therapeutic roll or ball.Key Words: large therapeutic roll, Swiss Ball, aerobic exercise, exercise intensity 相似文献18.
