Abstract
BACKGROUND Supervised exercise therapy (SET) is the cornerstone of medical therapy for symptomatic peripheral artery disease (PAD). Despite the efficacy of SET, initial reports following the 2017 Centers for Medicare and Medicaid Services (CMS) reimbursement decision indicate low SET uptake, referral, and completion. Vascular medicine specialists are key to the success of such programs. We examined rates of SET referral, completion, and outcomes in a health system with a robust SET program during the first 5 years of CMS reimbursement. METHODS A retrospective chart review of patients with PAD referred to SET between October 1, 2017 and December 31, 2022 was conducted. Patient demographic and medical characteristics, SET indication, referring provider specialty, SET participation (e.g., exercise modality, number of sessions, treadmill prescription), and outcomes were abstracted. Descriptive statistics, t-tests, and multiple linear regression were used to examine the sample, evaluate outcomes, and explore outcomes by relevant covariates (i.e., age, sex, referring provider specialty). RESULTS Of 5320 patients with PAD, N = 773 were referred to SET; N = 415 enrolled and were included in the present study. Vascular medicine and vascular surgery specialists were the two primary sources of referrals (30.6% and 51.6%, respectively). A total of 207 patients (49.9%) completed SET. Statistically significant and clinically meaningful improvements were observed in all outcomes. CONCLUSION SET referral and completion rates are low in the 5 years following CMS reimbursement, despite the advocacy of vascular medicine specialists. SET is effective in improving patient functional capacity and quality of life. Additional efforts are needed to increase both SET availability and referrals as part of comprehensive treatment of PAD.

Abstract
PURPOSE National guidelines for the treatment and management of symptomatic peripheral artery disease (PAD) recommend supervised exercise therapy (SET) as a first line of therapy. However, it is unknown how these expert opinion-based SET guidelines work in clinical practice as SET programs become established following the 2017 Centers for Medicare & Medicaid Services coverage announcement. The purpose of this prospective, nonrandomized translational study was to evaluate the clinical effectiveness of a SET program and specifically walking exercise modalities that did not incorporate a treadmill (TM). METHODS Participants enrolled in a 12-wk SET program housed in four rural Midwest cardiac rehabilitation settings and were prescribed an exercise program by an exercise physiologist or nurse based on current SET guidelines. Groups included TM walking, total body recumbent stepping (TBRS), TM walking + TBRS, and multimodal. Pre- and post-tests of walking capacity, physical function, and quality of life were administered. RESULTS The sample (n = 93) was all White, with 55% female representation, age of 73.7 ± 9.0 yr, and mild-moderate PAD (ankle-brachial index = 0.71 ± 0.19). Collectively, SET significantly improved the 6-min walk test (32.1 ± 6.6 m; P < .01). Within-group changes in the 6-min walk test were seen for all groups except the multimodal group; there were no significant between-group differences in change scores ( P = .30). No significant between-group changes were seen for the TM walking, TBRS, and TM walking + TBRS groups for physical function measures. CONCLUSION This study demonstrates the clinical effectiveness of SET programs following current guidelines and potential utilization of non-TM walking modalities in SET programs.

Abstract
PURPOSE This review encompasses several practical components of supervised exercise therapy (SET) for patients with claudication including referral, exercise training, and billing issues. Real-life SET session examples are also provided. SET was approved for reimbursement by the Centers for Medicare & Medicaid Services (CMS) in 2017, and there is continual growth of programs offering SET and in participation. The purpose of this review is to provide useful information for the clinical exercise professionals working with these patients. REVIEW METHODS The 2016 ACC/AHA Guideline on the Management of Patients With Lower Extremity Peripheral Artery Disease (PAD) provided a class I (highest level) recommendation for the use of SET in those with symptomatic PAD. Since there has been much growth in the literature about the utility of SET, the literature was reviewed (PubMed) to provide information for this article. Topics reviewed include the benefits of exercise training, exercise prescription, billing, referral and participation, and best practices. SUMMARY SET should be offered to all patients with symptomatic PAD who are not at risk of acute limb ischemia. For optimal results, SET should be implemented several times per week and in a progressive process to increase exercise intensity as tolerated. For best results, programs should recommend patients supplement SET with home exercise. Considerations for utilizing reimbursed sessions should also be discussed because patients have a maximum of 72 sessions/lifetime. Referral practices need refinement, and participation rates remain extremely low and may be influenced by demographics. Research on best practices and home or hybrid training must continue to address issues related to common enrollment and participation barriers. CONDENSED ABSTRACT Supervised exercise training (SET) for symptomatic peripheral artery disease is a class IA recommendation and reimbursable by most insurances. Improvements in walking performance can be dramatic. However, referral and participation in SET remain very low and thus SET is vastly underutilized.

Abstract
Peripheral artery disease (PAD) is an atherosclerotic vascular disease resulting in widespread morbidity and mortality, particularly among older adults. One first-line therapy to improve symptoms, function, and clinical outcomes in PAD is supervised exercise therapy (SET), which is based primarily on a structured, start-and-stop walking protocol and is implemented in cardiac rehabilitation programs. SET is supported by a Class IA guideline for patients with symptomatic PAD; however, despite the effectiveness of SET and the 2017 CMS decision to cover SET for PAD, challenges of awareness, access, and implementation of SET persist. Recent efforts to address these challenges include digital health and hybrid approaches to SET that may minimize barriers to care by delivering SET in more innovative, flexible formats. Further study is needed to understand barriers, improve awareness, and implement SET in more equitable and accessible ways.

Abstract
Background: Treadmill walking is the most commonly recommended exercise modality in supervised exercise therapy (SET) for peripheral artery disease (PAD); however, other modalities may be equally effective and more tolerable for patients. The primary aim of this single-blind, randomized pilot study was to compare the feasibility, safety, and preliminary efficacy of a treadmill walking (TM) versus a total body recumbent stepping (TBRS) exercise program for treatment of PAD. Methods: Participants (n = 19) enrolled in a 12-week SET program and were randomized to either a TM (n = 9) or TBRS (n = 10) exercise group that followed current SET exercise guidelines. Feasibility, safety, and efficacy outcomes were assessed. Results: SET attendance was 86% and 71%, respectively, for TBRS and TM groups (p = 0.07). Session exercise dose (metabolic equivalents of task [MET] minutes) (mean [SD]) for TM was 117.6 [27.4] compared to 144.7 [28.7] in the TBRS group (p = 0.08). Study-related adverse events were nine in 236 training hours and three in 180 training hours for the TBRS and TM groups, respectively. There were no significant differences between groups for improvement in 6-minute walk distance (mean [SD]) (TM: 133.2 ft [53.5] vs TBRS: 154.8 ft [49.8]; p = 0.77) after adjusting for baseline 6-minute walk distance. Conclusion: This is the first randomized study comparing TBRS to TM exercise in SET using current SET guidelines. This pilot study showed that TBRS is a feasible and safe exercise modality in SET. This study provides preliminary efficacy of the use of TBRS exercise in SET programs following current guidelines. Larger studies should be conducted to confirm these findings.

Abstract
Nonresponse to exercise has been extensively examined in young athletes but is seldom reported in studies of aerobic exercise interventions in older adults. This study examined the prevalence of nonresponse and poor response to exercise in functional and quality of life outcomes and response patterns between and among older adults undergoing 12-weeks of supervised exercise therapy for the management of peripheral artery disease (N = 44, mean age 72.3 years, 47.7% female). The prevalence of nonresponse (no change/decline in performance) in walking distance was 31.8%. The prevalence of poor response (lack of a clinically meaningful improvement) was 43.2%. Similar patterns of response were observed in both objective and patient-reported measures of physical function. All participants improved in at least one outcome; only two participants improved in all measured outcomes. Additional research should examine modifiable predictors of response to inform programming and maximize an individual's potential benefit from exercise therapy.

Abstract
Supervised exercise therapy (SET) is a first-line treatment for people with peripheral artery disease (PAD). However, data on patient adherence to SET are limited. In addition, while intermittent treadmill exercise has been widely tested, no studies have investigated recumbent total body stepping (step-ex). We examined whether exercise mode (treadmill walking [n = 17], step-ex [n = 18], or a multimodal approach [n = 18]) affected adherence to a 12-week SET program. We also investigated the potential safety and viability of step-ex for people with PAD by looking at change in exercise training capacity (highest metabolic equivalent of tasks [METs] achieved and highest total MET-minutes achieved per session). The 53 participants comprised 50% female candidates (n = 26) and were (mean [SD]) 74.2 (8.3) years old, with an ankle-brachial index of 0.70 (0.19). Overall adherence to SET was 62%. There was a difference in adherence between groups (P = .022), with the multimodal group (73.6% [21.5%]) higher than the treadmill group (50.2% [28.8%], P = .010). Treadmill participants (n [%]) (8 [47.1%]) dropped out at a higher rate than the multimodal group (3 [16.7%], P = .053). All groups increased the exercise training capacity. The multimodal group achieved greater improvement in total MET-minutes achieved per session (61.5 [45.1]) than the treadmill group (14.7 [44.3]) (P = .008).A multimodal approach to PAD exercise therapy resulted in higher adherence and greater change in exercise training capacity. Step-ex was safe for people with PAD. While further study is warranted, it is appropriate for SET programs to consider a multimodal approach using step-ex, especially given the varied health and physical ability of the PAD population.

Abstract
Patients with lower-extremity peripheral artery disease (PAD) have greater functional impairment, faster functional decline, increased rates of mobility loss, and poorer quality of life than people without PAD. Supervised exercise therapy (SET) improves walking ability, overall functional status, and health-related quality of life in patients with symptomatic PAD. In 2017, the Centers for Medicare & Medicaid Services released a National Coverage Determination (CAG-00449N) for SET programs for patients with symptomatic PAD. This advisory provides a practical guide for delivering SET programs to patients with PAD according to Centers for Medicare & Medicaid Services criteria. It summarizes the Centers for Medicare & Medicaid Services process and requirements for referral and coverage of SET and provides guidance on how to implement SET for patients with PAD, including the SET protocol, options for outcome measurement, and transition to home-based exercise. This advisory is based on the guidelines established by the Centers for Medicare & Medicaid Services for Medicare beneficiaries in the United States and is intended to assist clinicians and administrators who are implementing SET programs for patients with PAD.

Abstract
The effectiveness of an individual six-month-long physical exercise program in improving health-related quality of life (HRQOL) is unclear. There is some evidence that an individual exercise program can be effective for this aim. The goal of this study was to compare an individual six-month-long physical exercise program for patients with PAD (Peripheral Arterial Disease) with a traditional exercise program and find the effect of these programs on HRQOL and PAD risk factors. The study included patients who underwent femoral–popliteal artery bypass grafting surgery. Patients were divided into three groups: patients participating in an individual six-month-long physical exercise program (group I), in the standard physical activity program (group II), and in a control group (group III), with no subjects participating in rehabilitation II. Results: group I patients had a significantly (p < 0.001) higher HRQOL at 6 months after their surgery compared with groups II and III. The HRQOL scores were significantly (p < 0.05) lower after surgery among older (≥ 65), overweight participants, as well as among patients with diabetes mellitus and cardiovascular diseases when comparing study results with patients without these risk factors.
