Research on the Development and Implementation of an Exercise Rehabilitation Program for Aortic Dissection Patients After Percutaneous Intervention Based on the Behavior Change Wheel Theory

Condition(s) studied

Investigational drug(s) / intervention(s)

Routine: Inpatient Care: Continuously monitor vital signs (BP, HR, SpO₂), neurological status, and limb function; administer prescribed antihypertensives with thorough medication education and efficacy tracking. Strictly prohibit Valsalva maneuvers . Assess pain levels, wounds, and psychological state; deliver scheduled analgesics and emotional counseling to maintain stable mood. Implement lifestyle optimization: 7+hr sleep/night, portion-controlled nutrition, and gradual postoperative mobilization. Discharge \& Follow-up: Enforce BP control through medication adherence. Ban vigorous activities (mountaineering/swimming/competitive sports); allow low-stress aerobics . Distribute Exercise Diaries (Appx 6) mandating daily logs with critical warnings: STOP immediately if nausea, chest pressure, dizziness, dyspnea, or arrhythmia occur and urgent revisit. Require complete tobacco cessation and secondhand smoke avoidance.

BCW: 1.1 Assessment of physical fitness and formulation of individualized exercise rehabilitation plans 1.2 Inpatient Phase (Postoperative Day 1 - Week 1): Monitor via ICU Mobility Scale (IMS) before each session:▪ Score 0 : Passive range of motion (PROM) exercises▪ Scores 1-3 : Active bed-based joint mobility training▪ Scores 4-6 : Standing balance training▪ Scores 7-10 : Ambulatory walking training 1.3 Early Outpatient Phase (Weeks 2-4): Initiate when IMS=10:▪ Perform 6-Minute Walk Test (6MWT) ▪ If distance \>450m: Prescribe low-intensity aerobic walking " Speed: 3 km/h" Progression: Start at 10 min/day (≈500 steps), increase by 10 min every other day up to 40 min/day 1.4 Intermediate Rehabilitation (Weeks 5-12): Moderate-intensity aerobic walking + Resistance training :▪ Walking: 4-6 km/h, 30 min/session, 3 sessions/week▪ Resistance training: Seated elastic band exercises, 20 min/session, 2 sessions/week

Study summary

Study Title ： Effectiveness of a BCW Theory-Based Exercise Rehabilitation Program in Post-Endovascular Aortic Dissection Patients: A Randomized Controlled Trial

Primary Objective ： To determine whether an exercise rehabilitation program constructed based on the Behavior Change Wheel (BCW) framework improves postoperative quality of life (QoL) in patients undergoing endovascular aortic repair (EVAR).

Methodology ： Intervention Group (n= 40): Receives the BCW-based exercise rehabilitation protocol.

Control Group (n= 40): Receives routine care and health education . Outcome Measures ：

Primary Endpoint :QoL changes assessed via validated scales ( SF-36) at:

Pre-discharge (T0)

1 month postoperatively (T1) 3 months postoperatively (T2)

Secondary Endpoints (Daily Monitoring):

Exercise duration (minutes/day) Exercise intensity Post-exercise blood pressure (mmHg) Post-exercise heart rate (bpm)

Eligibility

Primary outcome measure(s)

• SF-36 — Preoperative，1 month postoperative，3 month postoperative
