简要总结
The goal of this prospective randomized controlled clinical trial is to evaluate the effects of video game-based physiotherapy and rehabilitation on functional exercise capacity and respiratory parameters in individuals with interstitial lung disease (ILD). The study also aims to compare the outcomes of video game-based rehabilitation with conventional physiotherapy, identify alternative breathing exercises for pulmonary involvement in ILD, and provide scientific evidence to guide clinical practice.
The main questions it aims to answer are:
Does video game-based rehabilitation improve respiratory function parameters in individuals with ILD?
Does video game-based rehabilitation reduce dyspnea and exercise intolerance, thereby improving functional exercise capacity?
Does video game-based rehabilitation increase participation and completion rates in pulmonary rehabilitation programs? Study Design: A total of 42 participants diagnosed with mild-to-moderate ILD will be recruited. Participants will be randomized into two groups (21 in the intervention group, 21 in the control group) using stratified randomization to ensure homogeneity by age, sex, and ILD type.
Arms: 2 (Intervention group and Control group)
Intervention:
Intervention group: Structured video game-based exercise training sessions as part of a pulmonary rehabilitation program.
Control group: Conventional pulmonary rehabilitation program.
Assessments: Respiratory function, functional exercise capacity, and symptom levels will be measured before and after the intervention.

详细描述
Interstitial lung diseases (ILDs) are chronic parenchymal disorders characterized by varying degrees of inflammation and fibrosis, leading to exertional dyspnea, exercise intolerance, ventilatory restriction, and reduced health-related quality of life. Beyond pulmonary involvement, patients often experience fatigue, peripheral muscle weakness, anxiety, and reduced participation in daily activities. Pulmonary rehabilitation is a key non-pharmacological strategy for ILD; however, adherence and completion rates remain limited due to barriers such as symptom burden, transportation, and the repetitive nature of conventional exercise training.
Technology-assisted rehabilitation, particularly video game-based training (exergaming), has emerged as a promising strategy to enhance motivation and adherence while preserving the physiological benefits of exercise. Exergaming provides real-time feedback, goal-oriented tasks, and progressive challenges that may improve enjoyment, engagement, and consistency of participation. In respiratory rehabilitation, game-guided breathing exercises may reinforce techniques such as pursed-lip breathing, diaphragmatic breathing, and thoracic expansion, which optimize ventilatory mechanics and potentially reduce dyspnea. Additionally, whole-body functional games can promote aerobic capacity, coordination, and peripheral muscle endurance.
This randomized controlled trial is designed to compare the effects of video game-based rehabilitation combined with conventional physiotherapy versus conventional physiotherapy alone in individuals with mild-to-moderate ILD. A total of 42 participants will be randomized into two parallel arms (intervention and control). The intervention arm will receive supervised video game-based exercise sessions in addition to standard pulmonary rehabilitation, while the control arm will perform conventional home-based physiotherapy and rehabilitation only.
Primary outcomes include changes in respiratory function parameters, functional exercise capacity, and symptom perception before and after the 8-week intervention. The study also aims to examine whether video game-based rehabilitation increases adherence and completion rates compared to conventional programs.
The expected impact of this study is to provide scientific evidence regarding the feasibility, safety, and effectiveness of integrating video game-based rehabilitation into pulmonary rehabilitation for ILD. If successful, this approach may help overcome barriers to participation, improve functional outcomes, and support broader implementation of engaging, patient-centered rehabilitation strategies.

结局指标
主要结局
Forced vital capacity (FVC)
时间窗: Day 1 and at the end of the eighth week
FVC will be measured using a spirometry test. During the assessment, participants will be instructed to take a full breath, and with a nose clip in place, exhale into the spirometer with maximum effort. The procedure will be repeated at least three times, and the best value will be recorded. Results will be expressed in liters (L) and compared to predicted values based on age, height, sex, and ethnicity. A value of ≥80% of the predicted capacity will be considered normal.
Forced Expiratory Volume in 1 Second (FEV₁)
时间窗: Day 1 and at the end of the eighth week
FEV₁ is defined as the volume of air that will be exhaled during the first second of a forced expiration after a full inspiration. It will be measured by spirometry and expressed in liters (L). Results will be compared to predicted values calculated according to age, height, sex, and ethnicity. A value of ≥80% of the predicted capacity will be considered normal.
FEV₁/FVC
时间窗: Day 1 and at the end of the eighth week
The FEV₁/FVC ratio is defined as the proportion of the forced expiratory volume in the first second (FEV₁) to the forced vital capacity (FVC). It will be measured by spirometry. Results will be expressed as a percentage and compared to predicted values according to age, height, sex, and ethnicity. A value of ≥70% will be considered normal, while lower values will indicate airflow limitation.
Peak Expiratory Flow (PEF)
时间窗: Day 1 and at the end of the eighth week
Peak Expiratory Flow (PEF) is defined as the maximum flow rate that will be achieved during a forced expiration after a full inspiration. It will be measured by spirometry and expressed in liters per second (L/s). The procedure will be repeated at least three times, and the best value will be recorded. Results will be compared to predicted values calculated according to age, height, sex, and ethnicity. A value of ≥80% of the predicted capacity will be considered normal.
Lung Diffusion Capacity
时间窗: Day 1 and at the end of the eighth week
Diffusing capacity (DLCO) measurement will be performed with the nose closed after the patient has not exercised before the test and has been sitting for at least 5 minutes. Care should be taken to ensure rapid inspiration. Inspiration time should be kept between 2 and 4 seconds. The final expiration should not exceed 4 seconds. Breath-hold times will be measured for all patients as recommended by the European Respiratory Society (ERS) guidelines. Tests with breath-hold times outside the 9-11 second range, inspirations with inspiratory vital capacity (IVC) below 90% during the DLCO maneuver, and measurements with alveolar ventilation below 10% of total lung capacity will be excluded from the study. DLCO measurements will be performed using gas chromatographs, and the results will be recorded as ml/min/mmHg. Hemoglobin-corrected tests will be used as the basis.
Peripheral muscle strength
时间窗: Day 1 and at the end of the eighth week
Peripheral muscle strength will be measured using a portable manual muscle strength measurement device (Hoggan MicroFet2 Handheld Dynamometer) for shoulder abductor and adductor, shoulder flexor, extensor, elbow flexor and extensor, hip flexor, extensor, hip abductor, adductor, knee flexor, and extensor muscles. Grip strength will be measured using a handheld dynamometer (Jamar, Nottinghamshire, UK) in a sitting position, with the elbow flexed at 90 degrees and the wrist in neutral. Measurements will be repeated three times for the right and left sides, and the average of the values will be recorded in Newtons (N).
Functional Exercise Capacity
时间窗: Day 1 and at the end of the eighth week
Functional exercise capacity will be assessed with the 6-minute walk test (6MWT). Participants are instructed to walk a 30-meter corridor with the goal of covering the longest possible distance in six minutes. Participants are allowed to stop and rest if necessary but are encouraged to continue walking as soon as possible. Participants' heart rate, blood pressure, peripheral oxygen saturation, self-perceived shortness of breath, and lower extremity muscle fatigue are questioned before and after the test. The distance traveled during the six-minute period is recorded. The 6MWT is a valid and reliable test for interstitial lung disease.
