The Effect of Walking Exercise in Patients With Chronic Obstructive Pulmonary Disease
- Conditions
- Chronic Obstructive Pulmonary Disease (COPD)
- Registration Number
- NCT07185659
- Brief Summary
"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.

- Detailed Description
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.

- Primary Outcome Measures
Name Time Method Hospital Anxiety and Depression Scale (HADS) Patients were assessed before discharge as the baseline, and reassessed at 4, 8, and 12 weeks post-discharge. 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.
modified Medical Research Council (mMRC) Patients were assessed before discharge as the baseline, and reassessed at 4, 8, and 12 weeks post-discharge. 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.
COPD Assessment Test (CAT) Patients were assessed before discharge as the baseline, and reassessed at 4, 8, and 12 weeks post-discharge. 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.
Chinese Version of the Pittsburgh Sleep Quality Index (CPSQI) Patients were assessed before discharge as the baseline, and reassessed at 4, 8, and 12 weeks post-discharge. 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.
Six-Minute Walk Test ( 6MWT ) Patients were assessed before discharge as the baseline, and reassessed at 4, 8, and 12 weeks post-discharge. 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.
- Secondary Outcome Measures
Name Time Method Daily walking activity:(1)total steps Patients were monitored over a 12-week period, with formal assessments conducted at 4, 8, and 12 weeks post-discharge. 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.
Daily walking activity:(2)total walking distance Patients were monitored over a 12-week period, with formal assessments conducted at 4, 8, and 12 weeks post-discharge. The Xiaomi Mi Band 4 wearable device will be used to measure daily walking activity, including total walking distance. 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.
Sleep status : (1)daily total sleep duration Patients were monitored over a 12-week period, with formal assessments conducted at 4, 8, and 12 weeks post-discharge. Daily total sleep duration (in hours) was measured using the Xiaomi Mi Band 4 wearable device. The data were collected to evaluate between-group differences and temporal changes. The effectiveness of the therapeutic intervention was investigated by comparing differences in sleep status over 12 weeks.
Sleep status : (2)daily light sleep duration Patients were monitored over a 12-week period, with formal assessments conducted at 4, 8, and 12 weeks post-discharge. Daily light sleep duration (hours) was measured using the Xiaomi Mi Band 4 wearable device. Data were collected to assess between-group differences and temporal changes. The effectiveness of the therapeutic intervention was evaluated by examining changes in sleep status over 12 weeks.
Sleep status : (3) Daily deep sleep duration Patients were monitored over a 12-week period, with formal assessments conducted at 4, 8, and 12 weeks post-discharge. Daily deep sleep duration (hours) was measured using the Xiaomi Mi Band 4 wearable device. Data were collected to assess between-group differences and temporal changes. The effectiveness of the therapeutic intervention was evaluated by examining changes in sleep status over 12 weeks.
Sleep status : (4) the number of awakenings during sleep Patients were monitored over a 12-week period, with formal assessments conducted at 4, 8, and 12 weeks post-discharge. The number of awakenings during sleep was measured using the Xiaomi Mi Band 4 wearable device. Data were collected to assess between-group differences and temporal changes. The effectiveness of the therapeutic intervention was evaluated by examining changes in sleep status over 12 weeks.
Sleep status : (5) total wake time during sleep Patients were monitored over a 12-week period, with formal assessments conducted at 4, 8, and 12 weeks post-discharge. Total wake time during sleep was measured using the Xiaomi Mi Band 4 wearable device. Data were collected to assess between-group differences and temporal changes. The effectiveness of the therapeutic intervention was evaluated by analyzing longitudinal changes in sleep status over 12 weeks."
