Prehabilitation is the process of optimizing physical functionality preoperatively to enable the individual to maintain a normal level of function during and after surgery. Prehabilitation training based on aerobic exercise, resistance exercise, breathing exercise, nutrition supplement and physiology management preoperatively could have a positive effect on the recovery of postoperative functional capacity in patients undergoing surgery.

Investigators try to construct a short home-based multimodal prehabilitation model based on internetwork in order to improve the efficiency of prehabilitation training, enhance the compliance of patients, and reduce the medical human resources and economic burden. In this study, prehabilitation guidance would be given to preoperative patients through network learning platform. Short-term multi-modal family strategy intervention would perform during the preoperative waiting period, and patients could upload their training records and obtain personalized training guidance by network learning platform follow-up management mode. Investigators would evaluate the feasibility of this model and evaluate its impact on improving the perioperative functional status and prognosis of patients.

Trimodal or multimodal prehabilitation strategy including exercise, diet and psychologic guidance could improve postoperative functional recovery for patients undergoing surgery. The development of internet medical provides possibility to improve the efficiency of patients' preoperative education, enhance the accuracy of prehabilitation execution, and reduce the medical human resources and economic burden.

This study tries to build the patient-centered network education and follow-up management based on the internet learning platform.

This is a prospective arm study. A total of 40 patients scheduled to have elective major thoracic, abdominal and retroperitoneal surgery (including thoracoscopic and laparoscopic surgery) will be recruited in this research at Peking Union Medical College Hospital. After informed consent is obtained, the baseline data (including basic information, past medical history, initial 6-minute walk distance, grip strength, pulmonary function et.al) will be collected. All patients will be guided to use the network learning platform which including details in text, pictures and videos of their individualized prehabilitation strategy after a complete assessment. Prehabilitation strategy is as follows: (1) quit smoking and abstinence; (2) a 5-minute warm-up exercise and a 25-minute aerobic exercise in the form of power walking, jogging, or cycling at least 3 times a week; (3) anaerobic exercise in form of bodyweight muscle training or pull strap training at least twice a week; (4) patients scheduled to have elective thoracic surgery also need to do breathing exercise in the form of blowing balloons, blowing the respiratory exerciser Tri-Ball, and active cycle of breathing techniques at least twice a day, 10 minutes each time; (5) nutritional advice and whey protein supplement 1 hour prior to exercise (20g/day for male and 15g/day for female patients); (6) psychological therapy by listening to soothing music and other relaxing activities. All details can be practiced with the reference to the standard videos in thenetwork learning platform. Patients will check the prehabilitation content daily and form their own training tasks in the network learning platform. Standardized short message interviews will be sent to patients twice a week to optimize adherence and promote timely feedback.

The length of prehabilitation will be 2-3 weeks, determined by the waiting time till surgery alone. After admission, the utilization rate of the prehabilitation network learning platform, the implementation of the prehabilitation strategy and the satisfaction with the network learning platform will be collected. Change of the following indicators from baseline to 1 day before surgery will be collected. The primary outcome is the change in 6-minute walk distance (6MWD), measured as functional walking capacity. The secondary outcomes include body-mass index(BMI), smoking cessation rate, grip strength, forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), FEV1/FVC, Duke Activity Status Index(DASI), Nutritional risk screening scale (NRS-2002), and Hospital Anxiety and Depression Scale (HADS).
