RESUMO
AIM: The "2024 ACC/AHA/AACVPR/APMA/ABC/SCAI/SVM/SVN/SVS/SIR/VESS Guideline for the Management of Lower Extremity Peripheral Artery Disease" provides recommendations to guide clinicians in the treatment of patients with lower extremity peripheral artery disease across its multiple clinical presentation subsets (ie, asymptomatic, chronic symptomatic, chronic limb-threatening ischemia, and acute limb ischemia). METHODS: A comprehensive literature search was conducted from October 2020 to June 2022, encompassing studies, reviews, and other evidence conducted on human subjects that was published in English from PubMed, EMBASE, the Cochrane Library, CINHL Complete, and other selected databases relevant to this guideline. Additional relevant studies, published through May 2023 during the peer review process, were also considered by the writing committee and added to the evidence tables where appropriate. STRUCTURE: Recommendations from the "2016 AHA/ACC Guideline on the Management of Patients With Lower Extremity Peripheral Artery Disease" have been updated with new evidence to guide clinicians. In addition, new recommendations addressing comprehensive care for patients with peripheral artery disease have been developed.

OBJECTIVE: A preoperative supervised exercise program (SEP) improves cardiorespiratory fitness and perioperative outcomes for patients undergoing elective abdominal aortic aneurysm (AAA) repair. The aim of this study was to assess the effect of a preoperative SEP on long-term survival of these patients. A secondary aim was to consider long-term changes in cardiorespiratory fitness and quality of life. METHODS: Patients scheduled for open or endovascular AAA repair were previously randomized to either a 6-week preoperative SEP or standard management, and a significant improvement in a composite outcome of cardiac, pulmonary, and renal complications was seen following SEP. For the current analysis, patients were followed up to 5 years post-surgery. The primary outcome for this analysis was all-cause mortality. Data were analyzed on an intention to treat (ITT) and per protocol (PP) basis, with the latter meaning that patients randomized to SEP who did not attend any sessions were excluded. The PP analysis was further interrogated using a complier average causal effect (CACE) analysis on an all or nothing scale, which adjusts for compliance. Additionally, patients who agreed to follow-up attended the research center for cardiopulmonary exercise testing and/or provided quality of life measures. RESULTS: ITT analysis demonstrated that the primary endpoint occurred in 24 of the 124 participants at 5 years, with eight in the SEP group and 16 in the control group (P = .08). The PP analysis demonstrated a significant survival benefit associated with SEP attendance (4 vs 16 deaths; P = .01). CACE analysis confirmed a significant intervention effect (hazard ratio, 0.36; 95% confidence interval, 0.16-0.90; P = .02). There was no difference between groups for cardiorespiratory fitness measures and most quality of life measures. CONCLUSIONS: These novel findings suggest a long-term mortality benefit for patients attending a SEP prior to elective AAA repair. The underlying mechanism remains unknown, and this merits further investigation.

OBJECTIVE: Supervised exercise therapy (SET) for patients with intermittent claudication (IC) can lower the risk of progression to chronic limb-threatening ischemia and amputation, while preserving and restoring functional status. Despite supporting evidence, it remains underutilized, and among those who initiate programs, attrition rates are extremely high. We hypothesize that socioeconomic factors may represent significant barriers to SET completion. METHODS: Patients with IC referred to SET at a multi-hospital, single-institution health care system (2018-2022) from a prospectively maintained database were retrospectively analyzed. Our primary endpoint was SET program completion and graduation, defined as completion of 36 sessions. Our secondary endpoints were vascular intervention within 1 year of referral and change in ankle-brachial index (ABI). Baseline demographics were assessed using standard statistical methods. Predictors of SET graduation were analyzed using multivariable logistic regression generating adjusted odds ratios (aORs) with 95% confidence intervals (CIs). Change in ABI was analyzed using t-test between subgroups. Reasons for attrition were tabulated. Patient Health Questionnaire-9 (PHQ-9), metabolic equivalent level, Vascular QOL, Duke Activity Status, and ABI were analyzed using paired t-tests across the entire cohort. RESULTS: Fifty-two patients met inclusion criteria: mean age 67.85 ± 10.69 years, 19 females (36.54%), mean baseline ABI of 0.77 ± 0.16. The co-pays for 100% of patients were fully covered by primary and secondary insurance plans. Twenty-one patients (40.38%) completed SET. On multivariable analysis, residence in a ZIP code with median household income <$47,000 (aOR, 0.10; 95% CI, 0.01-0.76; P = .03) and higher body mass index (aOR, 0.81; 95% CI, 0.67-0.99; P = .04) were significant barriers to SET graduation. There were no differences in ABI change or vascular intervention within 1 year between graduates and non-graduates. Non-graduates reported transportation challenges (25.00%), lack of motivation (20.83%), and illness/functional limitation (20.83%) as primary reasons for SET attrition. Metabolic Equivalent Level (P ≤ .01) and Duke Activity Status scores (P = .04) were significantly greater after participating in a SET program. CONCLUSIONS: Although SET participation improves lower extremity and functionality outcomes, only 40% of referred patients completed therapy in our cohort. Our findings suggest that both socioeconomic and functional factors influence the odds of completing SET programs, indicating a need for holistic pre-referral assessment to facilitate enhanced program accessibility for these populations.

OBJECTIVE: Supervised exercise therapy (SET) provides clinical benefit for patients suffering from intermittent claudication and has been widely recommended as first-line therapy before endovascular or surgical intervention. However, published rates of SET program completion range from 5% to 55%, with historic completion of 54% at our own institution. As such, we sought to identify if targeted patient-supportive interventions improve SET completion rates while still maintaining efficacious SET programming. METHODS: Patients who were diagnosed with intermittent claudication, as defined by ankle-brachial index (ABI) <0.9 without rest pain, were offered enrollment in a prospective quality improvement protocol for our 12-week SET for peripheral artery disease program. Program completion was defined as ≥24 of 36 offered sessions over 12 weeks. A three-pronged approach was utilized to improve completion during the study, including financial incentives up to $180, scheduled coaching with our advanced practitioner staff, and informational materials on the importance of SET programming and lifestyle modification. Patient-reported improvements in walking symptoms were tracked via regularly administered questionnaires. Functional measures of SET programming including total walking duration and distance, metabolic equivalent of task, and ABIs; vascular intervention within 12-months after enrollment was also collected and compared using univariate paired analysis. RESULTS: In total, seventy-three patients were enrolled in SET for peripheral artery disease programming over the study period. Utilizing our three-pronged coaching approach, 56 patients completed SET programming, increasing our SET completion rate to 76.7% over a 2-year study period. Compared with pre-SET baseline, patients who completed SET noted less pain, aching, cramps in calves when walking (P = .004), and less difficulty walking 1 block (P = .038). Additionally, patients significantly increased their metabolic equivalent of task (3.1 vs 2.6; P < .001), total walking duration (30 mins vs 13.5 mins; P < .001), and total walking distance (0.7 vs 0.3 miles; P < .001) from their pre-SET baseline. There were no changes in participant ABIs from enrollment to completion in participants. Patients who completed SET programming also delayed vascular intervention compared with those who did not complete SET or declined participation (213.5 vs 122.5 days from enrollment; P = .041). CONCLUSIONS: Targeted incentives, including cost-coverage vouchers and personalized coaching with instructional materials, successfully improved patient completion of a prescribed SET program. Patients who completed SET programming reported subjective improvement in walking symptoms and objective walking benefits. In addition, these patients had delayed time to vascular intervention, supporting current vascular guidelines advocating for effective SET therapy prior to offering vascular intervention for intermittent claudication.

BACKGROUND: Breast cancer is the most common female malignancy worldwide and a major cause of morbidity and mortality. Exercise during adjuvant treatment improves function and relieves symptoms in breast cancer survivors. However, it is unclear if an unsupervised exercise programme may be as effective as a supervised multimodal group. We investigated the feasibility and efficacy of a centre-based multidimensional rehabilitation (MDR) programme for breast cancer survivors undergoing adjuvant treatment and compared it to an unsupervised home-based exercise (HE) programme. METHODS: Participants were self-allocated to either MDR or HE group. MDR participants underwent 24 supervised exercise classes and 10 education classes over 12 weeks. HE participants were instructed on a home exercise regime. Outcome measures, including the 6-min walk test (6MWT) and Frenchay Activities Index (FAI), FACT-Cognitive Function scale, and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, were conducted at baseline (W0), post-intervention (W12) and 6-months post-intervention (M6). Variance between time points and the 2 groups were analysed using a linear mixed model (unstructured covariance matrix) and adjusted with Bonferroni. RESULT: Twenty-five participants attended at least half of the MDR interventions, while 21 completed the HE interventions. The former showed significant improvement in 6MWT, from 406.88 m (W0) to 443.34 m (W12) to 452.81 m (M6), while the improvement in the HE group was not significant (407.67 m (W0) to 433.14 m (W12) to 430.96 m (M6)). Both groups showed a significant improvement in FAI, with earlier significant improvement noted at W12 in the MDR group (22.71 (W0) to 27.65 (W12) to 28.81 (M6)) compared to the HE group (23.16 (W0) to 26.47 (W12) to 29.85 (M6)). Dropout rate was 16% in the MDR group and 34% in HE group. Overall satisfaction with the MDR programme was high. CONCLUSION: Both MDR and HE programmes were feasible. MDR was superior in improving endurance and earlier return to instrumental activities for those who completed at least half of the sessions. Future studies could explore use of technology to improve adherence to exercise. TRIAL REGISTRATION: The study was registered with ClinicalTrial.gov on 01/04/2022 with the registration number NCT05306808.

Concurrent training has been postulated as an appropriate time-efficient strategy to improve physical fitness, yet whether the exercise-induced adaptations are similar in men and women is unknown. An unblinded randomized controlled trial was conducted to investigate sex-specific dose-response effects of a 24-week supervised concurrent exercise training program on cardiorespiratory fitness and muscular strength in young adults. One hundred and forty-four sedentary adults aged 18-25 years were assigned to either (i) a control group (n = 54), (ii) a moderate intensity exercise group (MOD-EX, n = 46), or (iii) a vigorous intensity exercise group (VIG-EX, n = 44) by unrestricted randomization. Cardiorespiratory fitness (VO2max ), hand grip strength, and one-repetition maximum of leg press and bench press were evaluated at baseline and after the intervention. A total of 102 participants finished the intervention (Control, n = 36; 52% women, MOD-EX, n = 37; 70% women, and VIG-EX, n = 36; 72% women). In men, VO2max significantly increased in the MOD-EX (~8%) compared with the control group and in the VIG-EX group after the intervention (~6.5%). In women, VO2max increased in the MOD-EX and VIG-EX groups (~5.5%) compared with the control group after the intervention. There was a significant increment of leg press in the MOD-EX (~15.5%) and VIG-EX (~18%) groups compared with the control group (~1%) in women. A 24-week supervised concurrent exercise was effective at improving cardiorespiratory fitness and lower body limbs muscular strength in young women-independently of the predetermined intensity-while only at moderate intensity improved cardiorespiratory fitness in men.

BACKGROUND: Proximal humerus fracture (PHF) is a common fragility fracture in older adults and can have a substantial impact on upper limb function. Although most patients with PHF can be treated nonsurgically, it is unknown whether older adults benefit from supervised exercise therapy after PHF. Therefore, the objective of this trial was to investigate whether 10 weeks of physiotherapist-supervised exercises once a week were superior to 10 weeks of unsupervised home-based exercises in older adults with a nonsurgically treated displaced 2-part PHF. METHODS: This was designed as an assessor-blinded, prospective, randomized controlled trial and took place in 3 Nordic countries. In total, 72 patients (≥60 years) with nonsurgically treated displaced 2-part PHF were randomized to either physiotherapist-supervised exercises once a week for 10 weeks, combined with daily home-based exercises, or to 10 weeks of daily unsupervised home-based exercises. The primary outcome measure was the Disability of the Arm, Shoulder, and Hand (DASH) with a primary endpoint at 3 months. Secondary outcomes were DASH (at 12 months), Constant-Murley Score, the 15D-instrument, Visual Analog Scale, General Self-Efficacy Scale, and Pain Catastrophizing Scale, with follow-up visits after 3 and 12 months. Non-union and patient death within 3 months were counted as complications. RESULTS: The mean age of the patients in both groups was 72 years. At 3 months follow-up, the mean DASH score in the supervised group was 25.9 (SD 16.0) compared to 22.4 (SD 18.9) in the unsupervised group. The mean between-group difference (3.5, 95% CI -5.0 to 12.5) was not clinically relevant. None of the secondary outcome measures presented any clinically relevant or statistically significant between-group differences at 3 or 12 months follow-up. One patient in the supervised group and 3 in the unsupervised group were diagnosed with non-union. One patient from each group died before 3 months follow-up. CONCLUSIONS: This trial provides no evidence that supervised exercises are superior to unsupervised home-based exercises in improving functional outcome or health-related quality of life in older patients with a nonsurgically treated 2-part PHF. Further, our results suggest that most older adults with a nonsurgically treated 2-part PHF can perform home-based exercises without the supervision of a physiotherapist.

OBJECTIVE: Provision, uptake, adherence, and completion rates for supervised exercise programs (SEP) for intermittent claudication (IC) are low. A shorter, more time-efficient, 6-week, high-intensity interval training (HIIT) program may be an effective alternative that is more acceptable to patients and easier to deliver. The aim of this study was to determine the feasibility of HIIT for patients with IC. METHODS: A single arm proof-of-concept study, performed in secondary care, recruiting patients with IC referred to usual-care SEPs. Supervised HIIT was performed three times per week for 6 weeks. The primary outcome was feasibility and tolerability. Potential efficacy and potential safety were considered, and an integrated qualitative study was undertaken to consider acceptability. RESULTS: A total of 280 patients were screened: 165 (59%) were eligible, and 40 (25%) were recruited. The majority (n = 31; 78%) of participants completed the HIIT program. The remaining nine patients were withdrawn or chose to withdraw. Completers attended 99% of training sessions, completed 85% of sessions in full, and performed 84% of completed intervals at the required intensity. There were no related serious adverse events. Maximum walking distance (+94 m; 95% confidence interval, 66.6-120.8 m) and the SF-36 physical component summary (+2.2; 95% confidence interval, 0.3-4.1) were improved following completion of the program. CONCLUSIONS: Uptake to HIIT was comparable to SEPs in patients with IC, but completion rates were higher. HIIT appears feasible, tolerable, and potentially safe and beneficial for patients with IC. It may provide a more readily deliverable, acceptable form of SEP. Research comparing HIIT with usual-care SEPs appears warranted.

BACKGROUND: Peripheral arterial disease, characterized as arterial atherosclerotic disease, can lead to insufficient flow in the lower extremities and ischemia, with the most common clinical manifestation being intermittent claudication (IC). In 2022, the Society for Vascular Surgery (SVS) developed appropriate use criteria for the management of IC that used this systematic review as a source of evidence. The objective of this study is to synthesize the findings of the systematic review and identify evidence gaps. METHODS: A comprehensive search of literature databases including MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus was conducted from January 1, 2000, to November 30, 2022. Noncomparative and comparative observational studies and randomized controlled trials were included. Included studies evaluated exercise therapy, endovascular or open revascularization for the treatment of IC. Outcomes of interest (freedom from major adverse limb event, health-related quality of life, and walking distance) were compared in various subgroups (age, sex, diabetes, smoking status, anatomical location of disease, and optimal medical therapy). RESULTS: Twenty-six studies reported the outcomes of interest for the evidence map. The general conclusions of the studies that reported freedom from major adverse limb events were that reintervention rates for endovascular therapy at ≥2 years were >20%, major amputation rates were often not reported, and, after endovascular therapy, the 1-month mortality was low (<2%). Quality of life and walking distance data were sparse, limited to only endovascular intervention, and insufficient to make any strong conclusions. CONCLUSIONS: IC in patients with peripheral arterial disease poses a significant socioeconomic and health care burden. Major, consequential gaps exist in the IC literature with respect to the assessment of patient reported outcome measures, standardized measures of walking distance and the comparative effectiveness of initial exercise therapy vs invasive intervention. The evidence gaps identified by the Society for Vascular Surgery appropriate use criteria on IC systematic review serve as a guide for future research efforts to optimize care for this patient population.

OBJECTIVE: Individual unsupervised home-based exercise programs can enhance muscle strength, physical function, gait, and balance in older adults. However, the effectiveness of such programs may be limited by the lack of supervision. This study aims to verify the effectiveness of individual unsupervised home-based programs, compare the effects of individual unsupervised home-based to supervised programs, and verify the influence of supervision over individual unsupervised home-based programs on the physical function of older adults. METHODS: A systematic literature search was performed in four electronic databases, and the trials involved randomized controlled comparing the home-based programs to supervised, control groups, or home-based + supervised evaluating the muscle strength, physical function, gait, and balance in older adults. RESULTS: Eleven studies met the inclusion criteria. The meta-analysis revealed no differences between home-based program versus supervised program in gait, mobility, and balance, revealing a trend of significance to supervised program on strength (standardized mean difference [SMD] = 0.27, p = .05). The analysis revealed effects in mobility (SMD = 0.40, p = .003), balance (SMD = 0.58, p = .0002), and muscle strength (SMD = 0.36, p = .02) favoring home-based program versus control group. Significant effects between home-based program versus home-based + supervised program were observed in balance (SMD = 0.74, p = .002) and muscle strength (SMD = 0.58, p = .01) in favor of home-based + supervised program. CONCLUSION: Home-based programs effectively improve older adults' physical function compared with control groups. However, supervised programs were more effective for muscle strength.

OBJECTIVE: Clinical practice guidelines recommend supervised exercise therapy (SET) as first-line therapy for patients with peripheral artery disease (PAD) and intermittent claudication (IC). The Society for Vascular Surgery Appropriate Use Criteria for IC deems excercise therapy (ET) as appropriate for all patients with IC. However, compliance with recommendations for the use of ET is often poor owing to the lack of availability, patient travel requirements, and cost. Results of home-based ET programs have been mixed with a trend toward improved results with more frequent patient engagement. The feasibility, use, and effectiveness of a 12-week app-based structured ET program using cognitive-behavioral therapy (CBT) techniques for IC was evaluated. METHODS: Patients with PAD confirmed by an abnormal ankle-brachial index or toe-brachial index and IC were recruited prospectively to participate in Society for Vascular Surgery SET, a 12-week app-based ET program. Participants performed home 6-minute walk tests, completed quality-of-life surveys, received education options via micro learning courses (eg, What is PAD?, Exercise, and Nutrition), and ongoing health coaching using CBT techniques. They were instructed to record at least three 30-minute ET walks a week using their personal mobile phones. Programming also included daily doses of health education, coaching, and reminders sent via text message. RESULTS: One hundred thirty-nine patients (37% women; mean age, 65 years) were enrolled across 20 institutions (44% offered in-person ET programs). One hundred twenty patients (86%) completed the program. Participants recorded 201,163 minutes of walking 8,013,520 steps with the ET program, completing a total of 5049 SET walks. Nineteen enrolled participants (14%) became inactive because they either paused (14 participants: medical reasons, travel, or other) or withdrew (5 participants: security concerns, lack of motivation). Ninety-two percent of patients met their stated CBT specific, measurable, achievable, relevant, and time-bound goals. Freedom from intervention at 6 months was 92% and 69% at 12 months. CONCLUSIONS: Deployment of a 12-week app-based ET program for PAD incorporating CBT was feasible in achieving 86% program completion and effective at meeting guideline recommended activity goals. Ninety-two percent of participants achieved their CBT specific, measurable, achievable, relevant, and time-bound goals. The use of ET was increased by virtue of offering this program at institutions that did not offer ET.

BACKGROUND: Understanding the motivational effects of supervised aerobic high-intensity interval training (HIIT) may help men with prostate cancer undergoing active surveillance initiate and maintain exercise behavior, however, few studies have addressed this question. This report explored exercise motivation in men with prostate cancer undergoing active surveillance participating in a randomized exercise trial. METHODS: The Exercise during Active Surveillance for Prostate Cancer (ERASE) trial randomized 52 men with prostate cancer on active surveillance to the HIIT exercise group or the usual care (UC) group. The exercise program was supervised aerobic HIIT conducted three times per week for 12 weeks. The motivation questions were developed using the Theory of Planned Behavior and included motivational constructs, anticipated and experienced outcomes, and barriers to HIIT during active surveillance. RESULTS: The HIIT group attended 96% of the planned exercise sessions with 100% compliance to the exercise protocol. Motivation outcome data were obtained in 25/26 (96%) participants in the HIIT group and 25/26 (96%) participants in the UC group. At baseline, study participants were generally motivated to perform HIIT. After the intervention, the HIIT group reported that HIIT was even more enjoyable (p < 0.001; d = 1.38), more motivating (p = 0.001; d = 0.89), more controllable (p < 0.001; d = 0.85), and instilled more confidence (p = 0.004; d = 0.66) than they had anticipated. Moreover, compared to UC, HIIT participants reported significantly higher perceived control (p = 0.006; d = 0.68) and a more specific plan (p = 0.032; d = 0.67) for performing HIIT over the next 6 months. No significant differences were found in anticipated versus experienced outcomes. Exercise barriers were minimal, however, the most often reported barriers included pain or soreness (56%), traveling to the fitness center (40%), and being too busy and having limited time (36%). CONCLUSION: Men with prostate cancer on active surveillance were largely motivated and expected significant benefits from a supervised HIIT program. Moreover, the men assigned to the HIIT program experienced few barriers and achieved high adherence, which further improved their motivation. Future research is needed to understand long-term exercise motivation and behavior change in this setting. TRIAL REGISTRATION: Clinicaltrials.gov, NCT03203460 . Registered on June 29, 2017.

OBJECTIVE: International guidelines recommend supervised exercise therapy (SET) as primary treatment for all patients with intermittent claudication (IC), yet primary endovascular revascularisation (ER) might be more effective in patients with iliac artery obstruction. METHODS: This was a multicentre RCT including patients with IC caused by iliac artery stenosis or occlusion (NCT01385774). Patients were allocated randomly to SET or ER stratified for maximum walking distance (MWD) and concomitant SFA disease. Primary endpoints were MWD on a treadmill (3.2 km/h, 10% incline) and disease specific quality of life (VascuQol) after one year. Additional interventions during a mean follow up of 5.5 years were recorded. RESULTS: Between November 2010 and May 2015, 114 patients were allocated to SET, and 126 to ER. The trial was terminated prematurely after 240 patients were included. Compliance with SET was 57/114 (50%) after six months. Ten patients allocated to ER (8%) did not receive this intervention. One year follow up was complete for 90/114 (79%) SET patients and for 104/126 (83%) ER patients. The mean MWD improved from 187 to 561 m in SET patients and from 196 to 574 m in ER patients (p = .69). VascuQol sumscore improved from 4.24 to 5.58 in SET patients, and from 4.28 to 5.88 in ER patients (p = .048). Some 33/114 (29%) SET patients had an ER within one year, and 2/114 (2%) surgical revascularisation (SR). Some 10/126 (8%) ER patients had additional ER within one year and 10/126 (8%) SR. After a mean of 5.5 years, 49% of SET patients and 27% of ER patients underwent an additional intervention for IC. CONCLUSION: Taking into account the many limitations of the SUPER study, both a strategy of primary SET and primary ER improve MWD on a treadmill and disease specific Qol of patients with IC caused by an iliac artery obstruction. It seems reasonable to start with SET in these patients and accept a 30% failure rate, which, of course, must be discussed with the patient. Patients continue to have interventions beyond one year.

OBJECTIVE: The Vascular Quality of Life Questionnaire-6 (VascuQoL-6) is a short, disease specific instrument used to determine health related quality of life (HRQoL) in patients with peripheral arterial disease. This study aimed to assess the minimally important difference (MID) and substantial clinical benefit (SCB) of the VascuQoL-6 in Dutch patients with intermittent claudication (IC) receiving supervised exercise therapy (SET). METHODS: Consecutive patients with IC who were recruited from a single centre between January 2016 and December 2016 completed the VascuQoL-6 before initiation and after three months of SET. They subsequently answered an anchor question rating their current health status as much improved, improved, unchanged, deteriorated, or much deteriorated, compared with baseline. The MID for improvement and deterioration and SCB were calculated using anchor based and distribution based methods. RESULTS: A total of 124 patients with IC (58% male, mean age 68 years) completed the study protocol. Baseline VascuQoL-6 scores increased from 16.3 ± 4.4 to 18.7 ± 3.8 after three months of SET (p < .001). MID values ranged from +2.0 to +3.8 points regarding HRQoL improvement and from +0.2 to -2.2 points regarding HRQoL deterioration. The SCB ranged from +3.7 to +5.0 points. Depending on the MID approach, 32% - 41% of patients achieved a clinically meaningful improvement in HRQoL. CONCLUSION: Approximately one in three patients with IC reported a clinically meaningful improvement in HRQoL after three months of SET. The range of MID and SCB values provides caregivers with an idea of how much change in VascuQoL-6 scores is considered relevant or substantial by their patients. Applying cutoff points for MID and SCB may optimise the interpretation of trial results and may help to set a benchmark for success of SET.

BACKGROUND: A biopsychosocial rehabilitation is recommended for chronic nonspecific low back pain (CNLBP); however, its effectiveness compared to the traditional supervised exercise therapy of CNLBP treatment is still unclear. METHODS: This was a parallel-group randomized controlled clinical trial. The sample consisted of 180 participants of both sexes, aged ≥18 years, with CNLBP for ≥3 months. Using web randomization and concealed allocation, they were assigned to three groups; graded activity receiving cognitive-behavioral therapy, group-based combined exercise therapy and education (GA; n = 59), supervised group-based combined exercise therapy and education (SET; n = 63), and a control group receiving usual care (n = 58). Interventions were administered for 4 weeks (8 sessions). The primary outcome was pain intensity. Outcome measures were collected baseline, after interventions (4 weeks), and during two follow-up periods (3 and 6 months). RESULTS: After the intervention, GA had a significant large effect on pain reduction compared to the control group (MD of 22.64 points; 95% CI = 16.10 to 29.19; p < 0.0001; Cohen's d = 1.70), as well as SET compared with the control group (MD of 21.08 points; 95% CI = 14.64 to 27.52; p < 0.0001; Cohen's d = 1.39), without significant difference between two intervention groups. At 3 and 6 months of follow-up, GA had a statistically significantly better effect in reducing pain, disability and fear-avoidance beliefs, and improving spinal extensor endurance, range of extension and quality of life compared to SET and the control group. A statistically significantly better effect of SET compared with the control group was found in reducing pain, disability, fear-avoidance beliefs, and improving the physical component of quality of life. Harms were not reported. CONCLUSION: This study suggests that graded activity and group-based supervised exercise therapy have beneficial effects over the control group in the treatment of CNLBP. The graded activity was more beneficial than supervised group-based exercise therapy only during the follow-up. TRIAL REGISTRATION: Clinicaltrials.gov (NCT04023162; registration date: 17/07/2019).

BACKGROUND: Previous studies comparing surgical with nonsurgical treatment for lumbar spinal stenosis (LSS) reported that surgery is superior to nonsurgical treatments, but intensive and adequate volume of physical therapy were rarely performed. The purpose of this study was to compare the 1-year follow-up outcomes of patients with LSS treated with supervised physical therapy or surgery using propensity score-matched analysis. METHODS: A total of 224 patients with LSS who received supervised physical therapy (n = 38) or surgery (n = 186) were included, of which 66 were matched on baseline demographics, radiological findings, and patient-reported outcomes. The physical therapy group received supervised physical therapy twice weekly for 6 weeks. The physical therapy sessions included manual therapy, individually tailored exercises, cycling, and body-weight supported treadmill walking. The surgery group underwent decompression surgery with or without spinal fusion. A propensity score analysis was performed using a one-to-one nearest neighbor approach. RESULTS: The surgery group showed greater improvements in Zurich claudication questionnaire symptom severity and physical function, SF-36 physical functioning, bodily pain, and mental health, but had more severe stenosis and symptoms and mental health problems than the physical therapy group at baseline (P < 0.05). After propensity score matching, there were no significant differences in baseline characteristics, and all clinical outcomes at 1 year, except for a higher percentage of responders achieving minimum clinically important difference in the role-emotional subscale of SF-36 in the surgery group (P < 0.05). CONCLUSIONS: When baseline characteristics were considered, supervised physical therapy yielded similar effects to lumbar surgery. These results suggest that supervised physical therapy is preferred over surgery as first-choice treatment, to prevent complications and to minimize health care costs, especially in mild to moderate cases of LSS.

INTRODUCTION: Venous leg ulcer (VLU) is a therapeutic challenge. The mainstay of care is compression therapy and wound care. Exercise is also recommended for facilitating wound healing. This study aimed to determine whether adding tailored exercise training to conventional treatment would be superior on wound healing, ankle mobility, calf muscle function, and functional ability compared to those with the conventional treatment alone. METHODS: A randomized controlled trial, single-blinded was conducted. VLU patients were randomized to the conventional treatment plus tailored exercise training (intervention group) and the conventional treatment alone (control group) (12/group). The conventional treatment contained foam dressing and short-stretch bandage, while the tailored exercise training consisted of stretching, resistive, and aerobic exercise sessions (3-day/week, for 12-week). Primary outcomes included healing rate and wound size parameters. Secondary outcomes were ankle range of motion (ROM), calf circumference, calf muscle endurance and strength, and functional ability. All outcomes were assessed at baseline, 6-, and 12-week intervention. RESULTS: The intervention group had a higher trend of healing rate after 12-week training than those in the control group, but this trend was not significantly different (92% versus 58%, p = 0.06). After training, the intervention group had significantly decreased wound size. The intervention group had significantly higher ankle ROM and dorsiflexor muscle strength after 6- and 12-week training than those in the control group. CONCLUSION: Adding the tailored exercise training incorporated with the conventional treatment may provide a greater tendency on wound healing and have the potential to improve ankle mobility than the conventional treatment alone.

OBJECTIVE: Supervised exercise therapy (SET) is a first-line treatment for patients with peripheral artery disease (PAD). The efficacy of SET is most commonly expressed by significant statistical improvement of parameters that do not clarify how each individual patient will benefit from SET. This study examined the minimal clinically important difference (MCID) in walking speed in claudicating patients with PAD after SET. METHODS: A total of 63 patients with PAD-related claudication (Fontaine stage II PAD) participated in a 6-month SET program. Self-selected walking speed was measured before and after SET. Distribution and anchor-based approaches were used to estimate the MCID for small and substantial improvement. The ability to walk one block and the ability to climb one flight of stairs questions were chosen as anchor questions from the Medical Outcomes Study 36-item Short Form questionnaire. Receiver operating characteristics curve analyses were performed to detect the threshold for MCID in walking speed after treatment. RESULTS: The distribution-based method estimated 0.03 m/s as a small improvement and 0.08 m/s as a substantial improvement after SET. Small and substantial improvements according to the anchor question walking one block were 0.05 m/s and 0.15 m/s, respectively. For the climbing one flight of stairs anchor question, 0.10 m/s was a small improvement. Receiver operating characteristics curve analyses identified an increase of 0.04 m/s and 0.03 m/s for improvement based on walking one block and climbing one flight of stairs, respectively. CONCLUSIONS: We report our findings for the MCID for walking speed among claudicating patients receiving SET. Claudicating patients who increase walking speed of 0.03 m/s or greater are more likely to experience a meaningful improvement in walking impairment than those who do not. The MCID reported in this study can serve as a benchmark for clinicians to develop goals and interpret clinically meaningful progress in the care of claudicating patients with PAD.

BACKGROUND: Among people with lower extremity peripheral artery disease (PAD), little is known about variation in response to supervised exercise therapy (SET). Clinical characteristics associated with greater responsiveness to SET have not been identified. METHODS: Data from participants with PAD in two randomized clinical trials comparing SET vs nonexercising control were combined. The exercise intervention consisted of three times weekly supervised treadmill exercise. The control groups received lectures on health-related topics. RESULTS: Of 309 unique participants randomized (mean age, 67.9 years [standard deviation, 9.3 years]; 132 [42.7%] women; 185 [59.9%] black), 285 (92%) completed 6-month follow-up. Compared with control, those randomized to SET improved 6-minute walk distance by 35.6 meters (95% confidence interval, 21.4-49.8; P < .001). In the 95 (62.1%) participants who attended at least 70% of SET sessions, change in 6-minute walk distance varied from -149.4 to +356.0 meters. Thirty-four (35.8%) had no 6-minute walk distance improvement. Among all participants, age, sex, race, body mass index, prior lower extremity revascularization, and other clinical characteristics did not affect the degree of improvement in 6-minute walk distance after SET relative to the control group. Participants with 6-minute walk distance less than the median of 334 meters at baseline had greater percentage improvement in 6-minute walk distance compared with those with baseline 6-minute walk distance above the median (+20.5% vs +5.3%; P for interaction = .0107). CONCLUSIONS: Among people with PAD, substantial variability exists in walking improvement after SET. Shorter 6-minute walk distance at baseline was associated with greater improvement after SET, but other clinical characteristics, including age, sex, prior lower extremity revascularization, and disease severity, did not affect responsiveness to exercise therapy.

OBJECTIVE: Patients with intermittent claudication (IC) are initially treated with supervised exercise therapy (SET), as advised by national and international guidelines. Dutch health insurance companies and the Dutch National Health Care Institute suggested an 87% compliance rate with these guidelines in the Netherlands in 2017 and judged this to be undesirably low. The aim of this study was to evaluate compliance with IC guidelines and to elaborate on the reasons for deviating from them (practice variation) in a large teaching hospital. METHODS: A retrospective single centre cohort study was conducted at a large teaching hospital in the Netherlands. In total, 420 patients with newly diagnosed IC between 1 January 2017 and 31 December 2018 were analysed. Data included risk profiles and prescribed therapies. RESULTS: For all 420 included patients, the compliance rate with the guidelines for SET was 80.5%. The rate of adequately motivated and defensible practice variation was 15.7%; the rate of unjustified practice variation was 3.8%. Meaningful care was seen in 96.2% of cases. CONCLUSION: Deviation from IC guidelines was found in 19.5% of patients. Almost three quarters of this deviation can be explained by the decision to provide personalised, meaningful care.
