This study aims to evaluate the effects of a technology-assisted preoperative home-based exercise program, delivered through a LINE Official Account and LINE BOT, on postoperative hand-grip strength, muscle endurance, and psychological distress in patients undergoing thoracoscopic pulmonary nodule resection. The study adopts a single-group pretest post-test design and plans to recruit 60 eligible patients.
The intervention consists of at least one week of home exercise training before surgery, incorporating aerobic, resistance, and breathing exercises. Education, guidance, and interactive feedback are provided through the LINE platform to support adherence and exercise performance. Outcomes will be assessed at three time points: baseline (T0), immediately before surgery (T1), and two weeks after surgery (T2).
Patients with pulmonary nodules who are scheduled to undergo video-assisted thoracoscopic surgery for nodule resection (including wedge resection, segmentectomy, or lobectomy).
Aged 20 years or older and assessed by a healthcare provider as medically suitable to participate in exercise training.
At least one week between the date of enrollment and the scheduled surgery.
Willing to provide written informed consent and complete all study procedures, including joining the LINE Official Account, participating in the exercise training, completing questionnaires, and undergoing outcome assessments.
Metastatic tumors or contraindications to exercise participation.
Engagement in regular aerobic or resistance exercise within the past month (defined as ≥2 sessions per week, ≥30 minutes per session).
Inability to communicate in Mandarin or Taiwanese.
Inability to use technology-assisted applications (e.g., LINE APP).
Single group
Technology-Assisted Preoperative Home-Based Exercise Program
BehavioralThis behavioral intervention uses a technology-assisted approach to deliver preoperative home-based exercise training for patients scheduled to undergo video-assisted lung nodule resection. The intervention integrates a LINE Official Account with an automated LINE Bot that provides exercise instructions, educational materials, reminders, and self-report mechanisms. The exercise program is based on published preoperative home-exercise protocols for lung cancer surgery patients. It includes: 1. Aerobic exercise - walking or marching in place for 30 minutes, three times per week; 2. Resistance training - six exercises (high-knee marching, bridging, sit-to-stand, shoulder press, biceps curl, heel raise), performed twice weekly (non-consecutive), 30 repetitions each; 3. Breathing exercises - pursed-lip and diaphragmatic breathing, 10 repetitions each, three times per week; 4. Warm-up and cool-down for 5 minutes before and after exercise. The LINE Bot system provides video demonstration
Hand-grip Strength
Hand-grip strength will be measured using a calibrated handheld dynamometer. Measurements will be collected at three time points: Baseline at outpatient visit when surgery is scheduled (T0), Preoperative assessment on the day of admission (T1), Two weeks after surgery (T2). The primary outcome is the change in dominant-hand grip strength from T0 to T2. Higher values indicate greater muscle strength. The measure reflects postoperative functional recovery and the effectiveness of the technology-assisted preoperative exercise program.
