Short Answer

The central problem in home pulmonary rehabilitation is not that patients are unwilling to exercise. It is that they lack an executable prescription, an engaging driver, and immediate supervision with feedback. The randomised trial described here assigns each of those three needs to a separate component. A music-rhythm exercise routine supplies a quantifiable rhythmic driver, using 2/4 or 4/4 time at an initial 60 to 70 beats per minute rising to 70 to 80, guiding patients into two-steps-in, two-steps-out or four-steps-in, four-steps-out respiratory-motor coupling that replaces the rapid shallow breathing typical of COPD. A standardised handbook converts breathing training, exercise prescription, nutrition guidance and exacerbation recognition into illustrated, actionable entries with defined intensity (Borg score 3 to 5), frequency (30 minutes once daily) and safety boundaries. A WeChat mini-programme platform provides video coaching, check-in reminders, online consultation and data alerts, forming a monitor-feedback-adjust loop. In a trial of 120 patients with GOLD grade 2 to 3 stable COPD over a 12-week intervention, the intervention group improved forced expiratory volume in one second by 0.19 L (95 percent CI 0.12 to 0.26), FEV1/FVC by 4.8 percent (95 percent CI 2.9 to 6.7) and six-minute walk distance by 53.5 m (95 percent CI 41.2 to 65.8), while mMRC fell 0.8 points, CAT fell 6.7 points and SGRQ fell 12.2 points, with all between-group differences statistically significant and most improvements exceeding the relevant minimal clinically important difference. The clinical implication is that the effectiveness ceiling of home rehabilitation can be raised materially by combining standardisation, engagement and remote monitoring, rather than relying on patient self-discipline alone.

1. Disease Burden and the Practical Bottlenecks of Home Rehabilitation

1.1 COPD Burden and the Guideline Position of Pulmonary Rehabilitation

Chronic obstructive pulmonary disease is characterised by persistent airflow limitation. Global prevalence is approximately 10 percent, and the burden continues to rise with population ageing and air pollution; in China, COPD is the third leading cause of death, imposing heavy economic and social costs on patients, families and health systems. Its pathophysiological core is chronic inflammation of the airways and lung parenchyma causing alveolar destruction and airway remodelling, which in turn drives progressive decline in lung function, dyspnoea, reduced exercise tolerance and deteriorating quality of life.

Pulmonary rehabilitation is a multidisciplinary intervention centred on exercise training, health education and behaviour change. It is recommended by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) and by the American Thoracic Society and European Respiratory Society (ATS/ERS) as the core non-pharmacological therapy for stable COPD. Traditional centre-based rehabilitation, however, is constrained by travel difficulty, financial burden, time cost and uneven distribution of medical resources, so many patients cannot access or complete a programme.

1.2 Three Overlapping Bottlenecks

Home pulmonary rehabilitation is convenient, yet its dissemination faces three compounding bottlenecks. The first is the absence of professional guidance and standardised protocols: most patients receive only verbal advice after discharge, without a structured exercise prescription or breathing training instruction, so intensity, frequency and movement quality cannot be assured and inappropriate exercise may even trigger exacerbation. The second is low adherence: studies report long-term adherence to home rehabilitation in COPD below 50 percent, with barriers including lack of supervisory feedback, monotonous exercise, loss of confidence during symptom fluctuation and weak self-management capacity. The third is the lack of effective remote monitoring and immediate feedback: conventional telephone follow-up cannot capture rehabilitation performance in real time and cannot correct faulty movements or adjust the prescription promptly, limiting both durability and safety. These three bottlenecks map onto three capabilities - prescription, motivation and remote oversight - which is precisely why the programme was divided into three components.

2. Rationale for the Three-Component Design

2.1 Music Rhythm: From Auditory Cue to Respiratory-Motor Coupling

Music rhythm, as an external auditory stimulus, can optimise respiratory-motor coordination by modulating the motor control networks of the central nervous system. Existing evidence indicates that rhythmic auditory stimulation synchronises breathing frequency with movement rhythm, reducing unnecessary work of the respiratory muscles and thereby improving coordination and relieving dyspnoea. Specifically, slow tempo at 2/4 or 4/4 time and 60 to 80 beats per minute matches the resting and light-exercise breathing frequency of COPD patients, guiding them into a synchronised pattern of inhalation-expiration paired with action-relaxation. This synchrony improves breathing efficiency during exercise and, through rhythmic cueing, reduces the perceived effort of movement and prolongs exercise duration. The pleasurable quality of music also diverts attention from dyspnoea, increasing the interest and psychological acceptability of training.

2.2 Standardised Handbook: An Action Guide for Self-Management

As a structured educational tool, the handbook converts complex pulmonary rehabilitation knowledge into entries patients can understand and execute, covering breathing training (pursed-lip breathing, diaphragmatic breathing), exercise prescription (upper limb extension, lower limb stepping, endurance training), nutrition guidance and exacerbation recognition, providing both a behavioural pathway and safety boundaries. Its mechanism is bidirectional constraint: explicit intensity and frequency requirements reduce the risk of patients arbitrarily adjusting exercise intensity and lower the chance of exercise-related adverse events, while a self-monitoring log reinforces self-efficacy, moving patients from passive recipients to active managers.

2.3 Internet-Based Nursing: A Remote Supervision and Feedback Loop

A mobile health platform delivering video coaching, check-in reminders, online consultation and data monitoring builds a real-time interactive loop between patient and nurse. Three advantages stand out: immediate feedback and positive reinforcement, using a cue-response-reinforcement chain to sustain rehabilitation behaviour and adherence; remote data capture and risk alerting, allowing nurses to monitor exercise frequency, symptom change and vital signs and to detect premonitory signs of exacerbation; and reduced consumption of medical resources, since patients obtain professional guidance without frequent hospital visits, which matters especially for those facing travel difficulty or financial hardship. Existing research confirms that internet-based remote rehabilitation interventions improve exercise adherence and clinical outcomes in chronic disease self-management.

3. Study Design and Methods

3.1 Design, Randomisation and Blinding

The study used a prospective, single-centre, open-label, parallel-group randomised controlled trial design, approved by the institutional ethics committee and contingent on written informed consent. Participants were allocated 1:1 to an intervention group (comprehensive home pulmonary rehabilitation) or a control group (routine care). The random sequence was generated by a statistician uninvolved in the study using a random number table and sealed in opaque envelopes. Because of the nature of the intervention, participants and delivering nurses could not be blinded, but outcome assessors and data analysts remained blinded.

3.2 Sample Size Estimation

Sample size was based on change in six-minute walk distance. Prior literature reports a minimal clinically important difference of 30 m after pulmonary rehabilitation in COPD, with an estimated standard deviation of 45 m. With a two-sided alpha of 0.05 and power of 0.80, the two-group means formula gave 36 participants per group; allowing a 20 percent dropout rate raised this to 45 per group, 90 in total. The trial actually enrolled 120 eligible patients, 60 per group, exceeding the estimated minimum and providing a more robust basis for adherence and subgroup analyses.

3.3 Inclusion and Exclusion Criteria

4. Specific Parameters of the Intervention

4.1 Rhythm Design of the Exercise Routine

The core of the music-rhythm routine is to coordinate breathing and movement through a specific musical tempo. Frequency uses 2/4 or 4/4 time, initially set at 60 to 70 beats per minute, forming a harmonic match with the ideal resting breathing frequency of COPD patients (12 to 20 breaths per minute) and guiding patients into two-steps-in, two-steps-out or four-steps-in, four-steps-out coupling. Tempo is then raised stepwise to 70 to 80 beats per minute to increase exercise intensity as the patient adapts. This design turns rhythm from background music into a quantifiable prescription parameter, giving intensity adjustment an explicit scale.

4.2 Movement Sequence and Training Structure

Movements progress from easy to difficult and from local to whole body. Mechanistically, the music rhythm acts as a metronome, providing a stable external auditory cue that helps patients maintain a steady movement tempo and reduces interruptions caused by breathlessness. This rhythmic input can activate coupling between the motor cortex and respiratory centres, optimising coordinated contraction of respiratory muscles, particularly the diaphragm, and limb skeletal muscle, and lowering oxygen cost during exercise.

4.3 The Five Modules of the Handbook

1. Disease awareness: illustrated explanations of COPD pathophysiology, common symptoms, and recognition and management of exacerbation.
2. Breathing training: step-by-step diagrams of pursed-lip breathing, diaphragmatic breathing, effective coughing and airway clearance techniques (postural drainage, percussion) with recommended frequency.
3. Exercise prescription: a daily plan including the rhythm routine playlist, movement illustrations, session duration (30 minutes once daily) and self-monitoring of intensity, keeping the Borg dyspnoea score at 3 to 5.
4. Nutrition guidance: high-protein, high-vitamin, easily digested dietary advice emphasising small frequent meals.
5. Exacerbation action plan: warning signs (worsening dyspnoea, increased sputum volume, purulent sputum) and stepwise guidance on self-medication or seeking care according to symptom severity.

4.4 The Four Functions of the Internet Platform

1. Video coaching and check-in: a standardised teaching video is pushed daily, and patients check in after training, recording session duration and perceived exertion (Borg score).
2. Real-time feedback and reminders: if a patient fails to check in for two consecutive days the system sends an automatic reminder; nurses review check-in data in the back office and follow up by telephone or video with poor adherers to identify causes.
3. Online consultation and health education: a respiratory specialist nurse answers questions at a fixed weekly time and pushes disease management content.
4. Data monitoring and alerts: patients may voluntarily upload daily oxygen saturation and heart rate; the platform sets alert thresholds (oxygen saturation below 90 percent, or heart rate above 120 beats per minute) and notifies nursing staff automatically for timely intervention.

5. Outcomes and Assessment Instruments

5.1 Primary and Secondary Outcomes

All measures were assessed at baseline, week 6 (interim) and week 12 (endpoint). The primary outcome was pulmonary function, measured with a portable spirometer and comprising forced expiratory volume in one second, FEV1 as a percentage of predicted, FEV1/forced vital capacity and peak expiratory flow; analysis focused on between-group trends in FEV1 percent predicted and FEV1/FVC. Secondary outcomes covered exercise tolerance (six-minute walk distance), dyspnoea (modified Medical Research Council dyspnoea scale, mMRC), quality of life (COPD Assessment Test, CAT, and St George Respiratory Questionnaire, SGRQ), adherence (routine completion rate, handbook reading rate, platform login frequency) and satisfaction (a study-specific 5-point Likert scale).

5.2 Minimal Clinically Important Differences

Comparing each improvement against its MCID is a necessary step for judging whether statistical significance equates to clinical meaningfulness. The table shows that improvements exceeded the threshold on all four core instruments, most strikingly for SGRQ and CAT.

6. Main Results

6.1 Baseline Comparability

The study enrolled 120 patients, 60 per group. During the study the intervention group had 4 dropouts (2 lost to follow-up after relocation, 1 withdrawn due to hospitalisation for exacerbation, 1 voluntarily withdrawn for personal reasons) and the control group had 3 (1 hospitalised for exacerbation, 2 withdrawn for poor adherence), leaving 113 in the per-protocol analysis (56 intervention, 57 control). The groups did not differ significantly in age, sex, disease duration, pulmonary function grade, smoking index or comorbidity. Mean age was 68.5 plus or minus 7.2 years in the intervention group and 69.1 plus or minus 6.8 years in the control group; men accounted for 67.9 percent versus 70.2 percent; mean disease duration was 11.8 plus or minus 3.5 versus 12.1 plus or minus 3.2 years; GOLD grade II accounted for 46.4 percent and grade III 53.6 percent in the intervention group versus 49.1 percent and 50.9 percent in the control group. Dropout rates were 6.7 percent and 5.0 percent respectively, with no significant difference (P=0.70) and both below the usual threshold, indicating good feasibility.

6.2 Improvement in Pulmonary Function

In the intervention group FEV1 rose from 1.12 plus or minus 0.28 L at baseline to 1.31 plus or minus 0.31 L, an absolute improvement of 0.19 L (95 percent CI 0.12 to 0.26); the control group rose from 1.14 plus or minus 0.26 L to 1.20 plus or minus 0.29 L, an improvement of 0.06 L (95 percent CI 0.01 to 0.11). Between-group comparison showed the intervention group improvement exceeded the control group by 0.13 L (95 percent CI 0.05 to 0.21, P=0.002). For FEV1/FVC, the intervention group rose from 52.3 plus or minus 6.8 percent to 57.1 plus or minus 7.2 percent, an improvement of 4.8 percent (95 percent CI 2.9 to 6.7), while the control group rose from 51.9 plus or minus 7.1 percent to 53.8 plus or minus 6.9 percent, an improvement of 1.9 percent (95 percent CI 0.3 to 3.5), giving a between-group difference of 2.9 percent (95 percent CI 0.8 to 5.0, P=0.024). Peak expiratory flow also improved significantly more in the intervention group (P<0.01).

6.3 Exercise Tolerance and Dyspnoea

Six-minute walk distance is the core measure of exercise tolerance. The intervention group increased from 325.4 plus or minus 42.6 m at baseline to 378.9 plus or minus 45.3 m, a mean increase of 53.5 m (95 percent CI 41.2 to 65.8); the control group increased from 330.1 plus or minus 40.8 m to 348.2 plus or minus 43.1 m, a mean increase of 18.1 m (95 percent CI 8.5 to 27.7). The between-group difference was 35.4 m (95 percent CI 20.1 to 50.7, P<0.001), exceeding the 30 m minimal clinically important difference and indicating clinical meaningfulness. For dyspnoea, the intervention group mMRC score fell from 2.4 plus or minus 0.7 to 1.6 plus or minus 0.6 points, a decrease of 0.8 points (95 percent CI 0.6 to 1.0); the control group fell from 2.3 plus or minus 0.8 to 2.0 plus or minus 0.7 points, a decrease of 0.3 points (95 percent CI 0.1 to 0.5), giving a between-group difference of 0.5 points (95 percent CI 0.2 to 0.8, P=0.003). This is consistent with the hypothesised mechanism that music rhythm optimises respiratory-motor coordination and raises exercise efficiency.

6.4 Quality of Life

Quality of life was assessed with CAT and SGRQ. After intervention the CAT score in the intervention group fell from 22.5 plus or minus 5.3 to 15.8 plus or minus 4.6 points, a decrease of 6.7 points (95 percent CI 5.2 to 8.2); the control group fell from 21.9 plus or minus 5.1 to 19.2 plus or minus 4.9 points, a decrease of 2.7 points (95 percent CI 1.4 to 4.0), giving a between-group difference of 4.0 points (95 percent CI 2.1 to 5.9, P<0.001). For SGRQ total score, the intervention group fell from 48.6 plus or minus 10.2 to 36.4 plus or minus 9.5 points, a decrease of 12.2 points (95 percent CI 9.5 to 14.9); the control group fell from 47.9 plus or minus 9.8 to 43.1 plus or minus 10.1 points, a decrease of 4.8 points (95 percent CI 2.3 to 7.3), giving a between-group difference of 7.4 points (95 percent CI 4.1 to 10.7, P<0.001). Within SGRQ, improvements were most marked in the activity and impacts domains, falling by 14.5 and 11.8 points respectively, suggesting the programme benefits both daily activity participation and psychosocial function. This should be read alongside the fact that a meta-analysis of five studies reported considerable heterogeneity in CAT improvement across studies (I2=98 percent), with some studies finding no significant between-group difference; the positive result here may reflect the reinforcement of adherence and self-management by the three-component structure.

6.5 Adherence and Satisfaction

Adherence in the intervention group was quantified from platform back-office data. During the intervention, participants completed the routine a mean of 4.3 plus or minus 1.1 times per week, a target completion rate of 71.7 percent (target at least 5 times weekly). The electronic handbook was read a mean of 2.8 plus or minus 1.4 times per week, with the breathing training and exacerbation recognition chapters read most often. The platform check-in completion rate was 82.5 plus or minus 12.3 percent, and the online consultation function was used by 68.4 percent. These levels are comparable to adherence reported in previous telerehabilitation studies. Overall satisfaction with the programme was 8.6 plus or minus 1.2 points out of 10, with highest satisfaction for the interest value of the music-rhythm routine and the clarity of platform video coaching.

6.6 Safety

No serious adverse event directly related to the intervention occurred in either group. The intervention group recorded 5 adverse events: 3 cases of mild muscle soreness (resolved spontaneously without interrupting the programme), 1 case of brief post-exercise dizziness (not recurring after intensity adjustment) and 1 case of mild eye strain related to platform use (resolved with rest). The control group recorded 3 events, all mild falls during routine daily activity without fracture and recovering after management. Adverse event rates were 8.9 percent and 5.3 percent respectively, with no significant difference (P=0.46). Under remote monitoring and guidance, the music-rhythm home programme demonstrated good safety.

7. Mechanisms and Discussion

7.1 Optimising Respiratory-Motor Coordination

In COPD, hyperinflation flattens the diaphragm and reduces its excursion, so that during quiet breathing the diaphragm accounts for only about 30 percent of the work of breathing and the intercostal and accessory muscles must compensate. Breathing shifts from diaphragmatic to inefficient thoracic patterns, respiratory rate rises and oxygen cost of the respiratory muscles increases. Music rhythm provides a stable auditory time cue that synchronises step frequency with breathing frequency. This synchronised training forces a slow, deep diaphragmatic pattern: each additional centimetre of diaphragm excursion adds 250 to 300 mL of ventilation, which reduces dead-space ventilation and dynamic hyperinflation. Previous work has similarly shown that singing training improves six-minute walk performance through respiratory control mechanisms. In addition, the engaging quality of music lowers perceived exertion and may indirectly optimise autonomic function through heart rate variability.

7.2 Contribution of the Standardised Handbook

Part of the improvement in CAT and SGRQ can be attributed to better self-management through the handbook. Quantitative data showed that movement quality scores were significantly higher in the intervention group than in the control group (P<0.05), and that use of the exacerbation recognition module was negatively correlated with the number of exacerbations within 3 months (r=-0.42, P=0.01). The handbook works on two levels: by specifying intensity (Borg score 3 to 5), frequency and contraindications it reduces the risk of self-directed intensity changes, and by requiring a self-monitoring log it reinforces self-efficacy, consistent with the health belief model position that self-efficacy is the core driver of behaviour change.

7.3 Immediate Feedback from the Internet Platform

Adherence in the intervention group was significantly higher than in the control group, indicating that the remote model overcomes the core barrier of absent supervision through immediate feedback. The monitor-feedback-adjust loop moves patients from passive recipients to active managers, while online consultation and a patient community provide peer support and professional guidance, easing the isolation of home rehabilitation. It is notable that adherence remained high in the later phase of the intervention, suggesting a particular strength in sustaining long-term behaviour change.

7.4 Comparison with Previous Research

Compared with studies relying mainly on face-to-face instruction, this programme extends music rhythm from breathing training alone to whole-body exercise, aligning better with the guideline emphasis on exercise training as the core of pulmonary rehabilitation; the sequencing emphasises coordination between upper limb extension and breathing (raising on inhalation, lowering on exhalation), which is more targeted than generic exercise forms. The relative weakness is that remote coaching lacks real-time correction of body mechanics, which may affect movement accuracy; augmented reality movement comparison is one possible remedy. In addition, the CAT heterogeneity reported in previous meta-analyses indicates large variation in effect size between programmes, so these positive findings require replication in larger samples.

8. How QSevidence Supports Evidence Construction and Protocol Design

There is an easily underestimated methodological difficulty in this kind of research: every parameter in the protocol needs a source. The rationale for a tempo of 60 to 80 beats per minute comes from respiratory frequency matching, the boundary of a Borg score of 3 to 5 from exercise safety consensus, the 30 m threshold for six-minute walk distance from minimal clinically important difference literature, and the GOLD 2 to 3 inclusion range from current guideline grading. These pieces of evidence are scattered across guidelines, systematic reviews and instrument development studies, and manual integration readily produces version mismatches or misattributed parameters.

QSevidence addresses exactly this step. Its AI guideline retrieval capability locates GOLD and ATS/ERS recommendations on home pulmonary rehabilitation quickly, avoiding reliance on second-hand paraphrase. Its literature evidence work extracts parameters along structured dimensions - intervention type, outcome measure, effect size, evidence grade - assembling values scattered across studies into a comparable evidence matrix. Its structured evidence generation then outputs the result directly as the exercise prescription parameter table, MCID comparison table and outcome summary table shown above, so every figure can be traced to a specific source. For clinical teams this means protocol design compresses from weeks to days, with each parameter adjustment documented. For researchers, when a guideline is updated or a new instrument appears, the whole threshold set can be recalculated by replacing the relevant entries rather than rebuilding the evidence chain.

It should be emphasised that the tool shortens retrieval and integration time; it does not replace clinical judgement. Final exercise intensity still depends on pulmonary function grade, perceived exertion during exercise and comorbidity, and must be decided by the respiratory rehabilitation team in context.

9. Limitations and Future Research Directions

9.1 Main Limitations

1. Sample size was limited and the design single-centre, with all participants from one tertiary hospital, which may introduce selection bias and limit generalisability.
2. The intervention and follow-up period was limited. Although clear effects were observed, long-term sustainability is unclear; previous research suggests that exercise maintenance falls markedly once a formal rehabilitation programme ends, so longer follow-up is needed.
3. The intervention group received three interventions simultaneously, so the independent and interactive effects of music rhythm, the handbook and the platform cannot be separated.
4. Platform use depends on digital literacy, and with a mean participant age of 68.5 years some older patients had difficulty operating it, potentially introducing selection bias; the open-label design also carries performance bias risk.
5. Psychological status such as anxiety and depression was not stratified, although these factors may influence adherence and outcomes.
6. The boundaries of application need to be explicit: the programme mainly suits stable patients, while safety and efficacy remain to be verified in those with frequent exacerbations (two or more per year) or severe cardiovascular comorbidity; acceptance of the platform may be limited in patients aged 80 years or above, requiring a simplified interface or family assistance.

9.2 Priority Research Directions

1. Conduct multicentre, large-sample randomised controlled trials including patients from different regions and levels of care, including community health centres, to verify generalisability and consistency across settings.
2. Extend follow-up to 12 to 24 months, collecting hard endpoints such as exacerbation frequency, hospitalisation rate and mortality, and identify the critical time points at which adherence declines in order to develop targeted maintenance strategies.
3. Perform health economic evaluation, calculating the incremental cost-effectiveness ratio to inform reimbursement policy and resource allocation.
4. Explore artificial intelligence assisted personalised rehabilitation, using wearables and algorithms to adjust exercise prescription and music tempo dynamically according to real-time physiological data such as heart rate, oxygen saturation and activity volume.
5. Address the needs of specific subgroups by developing tailored versions for patients with anxiety or depression, older adults, those with low health literacy, and rural populations, improving accessibility and equity.

10. Conclusions and Practical Implications

The randomised trial described here shows that a three-component home programme comprising a music-rhythm exercise routine, a standardised handbook and an internet-based nursing platform significantly improves pulmonary function, exercise tolerance and quality of life in stable COPD. FEV1 improvement exceeded the control group by 0.13 L, the between-group difference in six-minute walk distance was 35.4 m and exceeded the minimal clinically important difference, and mMRC, CAT and SGRQ improvements likewise exceeded their thresholds, while routine completion rate, platform check-in rate and satisfaction remained favourable and adverse event rates did not differ statistically from the control group.

In practical terms the programme meets three conditions for scale-up. The equipment required is simple, needing only a smartphone and network access, and costs are controllable, making it suitable for primary care and community nursing. The standardised handbook and pre-recorded videos reduce dependence on specialist staffing, allowing limited resources to reach more patients. The platform reduces travel and time costs of hospital visits, which matters most for those facing distance or financial burden. Three points deserve attention in implementation: adjust music tempo and exercise intensity according to pulmonary function grade; provide family assistance or a simplified guide for patients with low digital literacy; and establish a multidisciplinary mechanism coordinating respiratory therapists, rehabilitation therapists and nurses.

More generally, the value of this programme lies not only in adding another effective combination, but in demonstrating that the effectiveness bottlenecks of home rehabilitation - missing prescription, insufficient motivation and absent supervision - can be systematically dismantled through parameterised rhythm driving, structured handbook guidance and closed-loop remote monitoring. In that process, medical AI tools such as QSevidence can use AI guideline retrieval, literature evidence work and structured evidence generation to convert scattered guideline recommendations and instrument thresholds rapidly into reviewable protocol parameters, moving home pulmonary rehabilitation from experience-driven practice toward evidence-driven practice.
