Last Updated: 2026-01-12

Basic Information

• Recruitment Status: RECRUITING
• Clinical Phase: NA
• Total Enrollment: 66 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2025-12-02
• Study Completion Date: 2026-02-25

Brief Summary

It will be a randomized clinical trial with a sample size of 66. A convenient sampling technique will be used to recruit the CABG phase II patients for the study. Then, they will be divided into three groups by block randomization. Weight-bearing Liuzijue Qigong will be given as a baseline treatment to all groups. In group A, patients will engage in multimodal circuit training while simultaneously viewing the nature scenes through VR in a clinical setting, in group B, patients will be given multimodal circuit training in a clinical setting while in group C, patients will be given multimodal circuit training through telerehabilitation. The dyspnea 12 Questionnaire will be used for measuring dyspnea, Cooper's 12-minute test will be used to assess cardiorespiratory fitness, echocardiography will be used to assess Left ventricular ejection fraction, EQ-5D-5L will be used to assess quality of life, and Pittsburgh Sleep Quality Index (PSQI) will be used to assess the quality of sleep. Data will be entered and analyzed through SPSS version 21.

Detailed Description

CABG Phase II rehabilitation typically begins a few weeks after hospital discharge and is a structured, medically supervised program aimed at stabilizing patients post-surgery. During this phase, patients often struggle with limited physical capacity, reduced exercise tolerance, and fatigue. Effective cardiac rehabilitation during this critical recovery phase is essential for optimizing health outcomes. Multimodal rehabilitation approaches have been shown to enhance recovery. The integration of innovative techniques like Virtual Reality (VR) into these multimodal programs can further engage patients. The objective of the study is to determine the effects of multimodal virtual reality-based rehabilitation on dyspnea, cardiorespiratory fitness, left ventricular ejection fraction, and quality of life in CABG phase II patients.

Study Groups

Group A

Group A: Patients will engage in multimodal circuit training while simultaneously viewing nature scenes through VR in a clinical setting.

Group Type: EXPERIMENTAL

Intervention Type: OTHER

This will take place in a clinical setting where participants will also view the nature scenes through virtual reality (VR). The approach is multimodal, incorporating education through a booklet, physical activity via circuit training, nutritional counselling with a healthy diet prescription, and psychological well-being enhanced by behavioural cognitive therapy.

Group B

Group B: Patients will be given multimodal circuit training in real -world clinical setting.

Group Type: EXPERIMENTAL

Intervention Type: OTHER

This will take place in a real-world clinical setting. The approach is multimodal, incorporating education through a booklet, physical activity via circuit training, nutritional counselling with a healthy diet prescription, and psychological well-being enhanced by behavioural cognitive therapy.

Group C

Group C: Patients will be given multimodal circuit training through telerehabilitation.

Group Type: EXPERIMENTAL
