Study summary

Peripheral artery disease (PAD) is a common atherosclerotic condition characterized by reduced blood flow to the lower extremities, leading to intermittent claudication, decreased walking capacity, and impaired quality of life. Supervised exercise therapy is recommended as the first-line non-invasive treatment for patients with PAD; however, participation in center-based programs is often limited due to accessibility, time constraints, and symptom-related barriers.

This randomized controlled study aims to evaluate the clinical effectiveness of a hybrid cardiac rehabilitation program compared with conventional supervised exercise therapy in individuals diagnosed with peripheral artery disease. Participants will be randomly assigned to either a hybrid cardiac rehabilitation group or a supervised exercise therapy group.

The hybrid cardiac rehabilitation program will combine center-based supervised exercise sessions with home-based telerehabilitation, supported by remote monitoring and wearable activity tracking devices. The supervised exercise therapy group will receive a fully center-based, physiotherapist-supervised exercise program. Both interventions will be delivered over a 12-week period.

Primary outcomes will include walking performance and functional capacity. Secondary outcomes will assess exercise adherence, symptom severity, physical activity levels, and quality of life. The results of this study are expected to provide evidence on the feasibility and effectiveness of hybrid cardiac rehabilitation as an alternative rehabilitation model for patients with peripheral artery disease.

Read the detailed description

Peripheral artery disease (PAD) is a manifestation of systemic atherosclerosis and is associated with impaired lower extremity perfusion, intermittent claudication, reduced functional capacity, and diminished quality of life. Supervised exercise therapy (SET) is strongly recommended by international guidelines as a first-line treatment for symptomatic PAD, as it improves pain-free and maximal walking distance and delays the need for invasive interventions. Despite its proven effectiveness, participation in center-based SET programs remains suboptimal due to logistical, socioeconomic, and symptom-related barriers.

Hybrid cardiac rehabilitation (HCR) has emerged as a promising alternative model that integrates center-based supervised exercise with home-based and telerehabilitation-supported interventions. This approach aims to preserve the clinical benefits of supervised exercise while improving accessibility, flexibility, and long-term adherence.

This study is designed as a randomized controlled, single-blind trial to compare the clinical effectiveness of hybrid cardiac rehabilitation with conventional supervised exercise therapy in patients diagnosed with peripheral artery disease. Eligible participants aged 50-70 years with stable intermittent claudication (Fontaine stages I-II or Rutherford categories 1-3) will be randomly allocated to either the hybrid cardiac rehabilitation group or the supervised exercise therapy group.

Both groups will participate in a structured 12-week exercise program conducted three times per week. The supervised exercise therapy group will receive fully center-based, physiotherapist-supervised aerobic and strengthening exercises. The hybrid cardiac rehabilitation group will initially participate in center-based supervised sessions, followed by a home-based telerehabilitation phase supported by real-time or asynchronous remote monitoring. Exercise intensity and progression will be individualized based on perceived exertion, symptom tolerance, and functional assessments. Wearable activity tracking devices will be used to objectively monitor physical activity and adherence.

Outcome assessments will be performed at baseline and after completion of the intervention period. Primary outcome measures will include pain-free walking distance, maximal walking distance, and functional exercise capacity. Secondary outcomes will include exercise adherence, lower extremity muscle strength, walking tolerance, claudication pain severity, daily physical activity levels, and patient-reported outcomes related to quality of life and psychological well-being.

By directly comparing hybrid cardiac rehabilitation with supervised exercise therapy in a randomized controlled design, this study aims to address an important gap in the literature and to determine whether hybrid cardiac rehabilitation represents a feasible and effective alternative treatment strategy for patients with peripheral artery disease.

    Change in Pain-Free Walking Distance during constant-load treadmill test. Distance walked (meters) from the start of treadmill walking (3.2 km/h, 12% incline) until the onset of claudication pain.

    Time frame: Baseline and Week 12

  2. Maximal Walking Distance

    Total distance walked (meters) from the start of treadmill walking (3.2 km/h, 12% incline) until maximal tolerable claudication pain (Likert scale level 4).

    Time frame: Baseline and Week 12

  3. Functional Capacity

    Change in functional capacity will be assessed using the 6-Minute Walk Test (6MWT) performed according to the American Thoracic Society (ATS) guidelines (2002). The total distance walked (in meters) during the 6-minute test will be recorded. The test will be conducted in a 30-meter corridor, with standardized instructions and encouragement protocols.

    Time frame: Baseline and Week 12

Secondary outcomes

  1. Muscle Strength

    Lower extremity muscle strength, balance, and functional mobility assessed using the Short Physical Performance Battery (SPPB), which includes a 4-meter gait speed test, chair stand test, and standing balance test. Each component is scored from 0 to 4, with a total score ranging from 0 to 12. Higher scores indicate better lower extremity physical performance.

    Time frame: Baseline and Week 12

  2. Walking Tolerance

    Walking tolerance will be assess with Walking Impairment Questionnaire (WIQ) total score. Self-reported walking limitation assessed using WIQ (score 0-100). The higher scores indicating better walking ability.

    Time frame: Baseline and Week 12

  3. Claudication Pain Severity

    Severity of claudication pain will be assessed using a 5-point Likert-type pain scale developed specifically for intermittent claudication, rated by the patient. The scale ranges from 0 (no pain) to 4 (maximum pain - unable to continue walking). Patients will be instructed to rate their worst pain during walking on this scale. Higher scores indicate worse pain severity.

    Time frame: Baseline and Week 12

  4. LDL Cholesterol (mg/dL)

    Serum LDL cholesterol concentration will be measured in mg/dL at baseline and week 12 using standard enzymatic colorimetric methods performed at the hospital's central biochemistry laboratory. Fasting blood samples (≥8 hours) will be used.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 24, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
