Telerehabilitation in Cancer Patients: Optimization of Prehabilitation and Rehabilitation Following Colorectal Resection

This study, titled: Telerehabilitation in Oncology Patients: Optimization of Prehabilitation and Rehabilitation Post-Colorectal Resection. Is a randomized clinical trial conducted at the Royo Villanova Hospital in Zaragoza, Spain. It aims to evaluate the effectiveness of a tele-rehabilitation program in enhancing functional capacity and quality of life for patients undergoing colorectal cancer surgery. Colorectal cancer (CRC) is a highly prevalent malignant tumor that significantly impacts global health and patients\&amp;#39; quality of life, particularly after surgery. Prehabilitation and postoperative rehabilitation are crucial for recovery, and telerehabilitation offers a promising alternative to improve outcomes in CRC patients.

Study Background and Rationale: Colorectal cancer (CRC) is one of the most prevalent malignant tumors worldwide and a leading cause of cancer-related deaths. Despite advancements in surgical and oncological treatments, patients often experience significant postoperative complications and a decline in their quality of life. Prehabilitation, which aims to enhance a patient's functional capacity before surgery, has been identified as a promising approach to improve postoperative outcomes. However, traditional rehabilitation programs are often limited by patient adherence, accessibility, and the availability of resources, especially for those living in rural or underserved areas.

Objective: The primary objective of this study is to determine whether a 2-week prehabilitation and 4-week post-surgical rehabilitation program delivered via asynchronous telerehabilitation software can improve the functional capacity of patients undergoing colorectal cancer surgery, as measured by the Six Minute Walking Test (6MWT). Secondary objectives include assessing changes in body composition, muscle strength, pulmonary capacity, postoperative complications, psychosocial factors (such as quality of life, anxiety, depression, and sleep quality), adherence to the treatment, patient acceptance of the treatment, and the usability of the telerehabilitation platform.

Study Design: This is a single-blind, parallel-group randomized clinical trial. Fifty-four patients scheduled for colorectal cancer surgery will be recruited and randomly assigned to either the control group, which will receive conventional rehabilitation through a booklet, or the intervention group, which will receive the same rehabilitation program through a digital telerehabilitation platform. Both groups will undergo a comprehensive rehabilitation program including therapeutic education, respiratory exercises, aerobic exercises, and strength training.

Methodology: Patients will be assessed at five time points: pre-intervention, the day before surgery, 21 days post-surgery, 50 days post-surgery, and 3-month follow-up. The telerehabilitation platform will allow patients to access exercise videos and therapeutic content asynchronously, with the ability to communicate with their physiotherapists through the platform for guidance and support. The booklet will allow patients to access the program through pictures and text.

Clinical implications: Telerehabilitation represents an innovative approach to overcoming barriers associated with conventional rehabilitation, particularly in improving accessibility for patients in remote areas. By demonstrating the clinical efficacy of telerehabilitation, this study aims to contribute to the optimization of rehabilitation protocols for oncology patients and to provide a scalable model for integrating digital health solutions into routine clinical practice.
