"Patients were divided into two groups: the experimental group (E group) and the control group (C group). The E group received standard care, walking exercise, and elastic band exercise, and wore a smart bracelet to record walking steps and sleep for three months. During the first month, participants performed walking exercise for 100 minutes per week and used a red elastic band for resistance training. In the second month, walking exercise increased to 150 minutes per week with a green elastic band. In the third month, walking exercise increased to 150-300 minutes per week with a blue elastic band. The C group wore the smart bracelet to record walking steps and sleep for three months. Each group included 34 participants. The study was conducted from September 9, 2021, to December 31, 2025. Exclusion criteria included panic disorder, cognitive impairment, current cancer treatment, angina pectoris or myocardial infarction within the past 3 months, participation in high-intensity rehabilitation exercise, and walking dysfunction. Participants were required to follow the study protocol.
Patients will be divided into two groups: the experimental group (E group) and the control group (C group).
The E group will receive standard care, walking exercise, and elastic band exercise, and will wear a smart bracelet to record walking steps and sleep for three months. During the first month, participants will perform walking exercise for 100 minutes per week and use a red elastic band for resistance training. In the second month, walking exercise will increase to 150 minutes per week with a green elastic band. In the third month, walking exercise will increase to 150-300 minutes per week with a blue elastic band.
The C group will wear a smart bracelet to record walking steps and sleep for three months.
Each group will enroll 34 participants. The study period is from September 9, 2021, to December 31, 2025. Participants with contraindications such as panic disorder, cognitive impairment, ongoing cancer treatment, angina pectoris or myocardial infarction within the past 3 months, participation in high-intensity rehabilitation exercise, or walking dysfunction will be excluded at enrollment based on the exclusion criteria. Participants are required to follow the study protocol.

| walking exercise and resistance exercise with elastic band | Experimental | From weeks 1 to 12, participants' daily walking steps were monitored using a wearable device (smart bracelet). Participants performed walking exercises 5 days per week, twice daily (morning and evening sessions). In weeks 1-4, the prescribed dose was 100 minutes per week (10 minutes per session); in weeks 5-8, 150 minutes per week (15 minutes per session); and in weeks 9-12, 150 to 300 minutes per week (20 to 30 minutes per session). Leg resistance extension exercises were also performed with progressively stronger elastic bands: red (weeks 1-4), green (weeks 5-8), and blue (weeks 9-12). During weeks 1-2 and 5-6, exercises were performed 3 times per week with 2 sets per session, which increased to 3 sets per session during weeks 3-4, 7-8, and 11-12. |

| Elastic band | Device | Thera-Band® elastic band exercise protocol: First stage (weeks 1-4): Participants performed leg resistance stretching exercises with a red elastic band. In weeks 1-2, exercises were performed 3 times per week, with 2 sets per session; in weeks 3-4, 3 times per week, with 3 sets per session. Second stage (weeks 5-8): Participants performed leg resistance stretching exercises with a green elastic band. In weeks 5-6, exercises were performed 3 times per week, with 2 sets per session; in weeks 7-8, 3 times per week, with 3 sets per session. Third stage (weeks 9-12): Participants performed leg resistance stretching exercises with a blue elastic band.

| Measure | Description | Time Frame |
|---|---|---|
| Hospital Anxiety and Depression Scale (HADS) | HADS was used to assess differences between groups and over time. The questionnaire consists of 14 items: 7 for anxiety and 7 for depression. Scores range from 0 to 21 for each subscale, with higher scores indicating greater levels of anxiety and depression. | Patients were assessed before discharge as the baseline, and reassessed at 4, 8, and 12 weeks post-discharge. |
| modified Medical Research Council (mMRC) | The mMRC scale was used to assess differences in dyspnea severity between groups over time. The mMRC is a five-point scale ranging from 0 (least severe) to 4 (most severe), with higher scores indicating greater dyspnea severity. | Patients were assessed before discharge as the baseline, and reassessed at 4, 8, and 12 weeks post-discharge. |
| COPD Assessment Test (CAT) | The COPD Assessment Test (CAT) was used to assess differences between groups over time. The CAT consists of 8 items scored from 0 to 5, yielding a total score of 0 to 40, with higher scores indicating a greater impact of COPD on quality of life. | Patients were assessed before discharge as the baseline, and reassessed at 4, 8, and 12 weeks post-discharge. |
| Chinese Version of the Pittsburgh Sleep Quality Index (CPSQI) | CPSQI was used to assess differences between groups over time. Scores range from 0 to 21, with higher scores indicating poorer sleep quality. A score greater than 5 denotes poor sleep quality. | Patients were assessed before discharge as the baseline, and reassessed at 4, 8, and 12 weeks post-discharge. |
| Six-Minute Walk Test ( 6MWT ) | The six-minute walk test (6MWT) was used to assess differences between groups and over time. It is an important measure of patients' functional exercise capacity. |

| Daily walking activity:(1)total steps | The Xiaomi Mi Band 4 wearable device will be used to measure daily walking activity, including total steps. Data will be collected to compare differences between two groups over time. By analyzing changes in walking activity over a 12-week period, the effectiveness of the therapeutic intervention will be evaluated. | Patients were monitored over a 12-week period, with formal assessments conducted at 4, 8, and 12 weeks post-discharge. |

Protecting participant privacy is the primary consideration, as sharing individual participant data (IPD) could expose sensitive information and create risks of re-identification, even after de-identification. Moreover, participants did not provide consent for data sharing, and obtaining re-consent would be difficult. Ensuring data security also requires substantial resources and technical safeguards that exceed our current infrastructure. In addition, compliance with complex legal and ethical regulations governing data sharing further complicates implementation. Finally, maintaining the quality and integrity of IPD prior to sharing demands additional effort and resources. Collectively, these factors inform our decision to prioritize participant protection and data security.
