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

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.

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
