網際網路在醫療領域的應用日益增長，計步器與網際網路的結合能改善肺阻塞病人的呼吸困難和身體活動已有零星的報告，但尚未有統合分析來確認其成效。我們運用統合分析方法，探查計步器結合網際網路於肺阻塞病人呼吸困難構面及身體活動構面的影響。首先以肺阻塞（chronic obstructive pulmonary disease）、計步器（pedometer）、網際網路（internet）、呼吸困難（dyspnea）、身體活動（physical activity）為關鍵字，系統性檢索2021年12月31日前發表於PubMed、Cochrane Library、Embase、EBSCOhost CINAHL、華藝線上圖書館和臺灣期刊論文索引等電子資料庫的隨機對照試驗。文獻品質採用CASP工具進行評讀。使用R軟體進行統合分析並評估效果量的異質性。本研究共收錄七篇文獻進行統合分析，結果顯示計步器結合網際網路於肺阻塞病人對呼吸困難構面在改良呼吸困難指標整體效果量無顯著差異（SMD=0.54, 95% CI=-0.14-1.23, Z=1.55, p=0.122），而對身體活動構面在每日步數整體效果量有顯著差異（SMD=0.23, 95% CI=0.04-0.42, Z=2.42, p=0.015），但在六分鐘步行測試整體效果量則無顯著差異（SMD=0.03, 95% CI=-0.11-0.18, Z=0.44, p=0.657）。根據本統合分析的結果顯示計步器結合網際網路於肺阻塞病人的每日步數有顯著的正面成效，但在改良呼吸困難指標及六分鐘步行測試方面並沒有足夠的證據顯示有顯著效益。

There have been sporadic reports on the combination of pedometers and the Internet to improve respiratory symptoms and physical activities in patients with chronic obstructive pulmonary disease (COPD). We aimed to conduct a meta-analysis of randomized controlled trials (RCTs) to investigate the issue. We searched the keywords «chronic obstructive pulmonary disease,» «pedometer,» «Internet,» «dyspnea,» and «physical activity» before December 31, 2021, from databases of PubMed, Cochrane Library, Embase, EBSCOhost CINAHL, Airiti Library, and NCL Taiwan Periodical Literature. The quality was assessed using the CASP tool. Meta-analysis was performed using R software. A total of seven articles were included in the meta-analysis. The results showed that the combination of pedometers and the Internet had no significant difference on modified Medical Research Council (mMRC) dyspnea scale (SMD=0.54, 95% CI=-0.14-1.23, Z=1.55, p=0.122) and the distance of six-minute walking test (6MWT) (SMD=0.03, 95% CI=-0.11-0.18, Z=0.44, p=0.657). However, there was a significant difference on the daily step counts (SMD=0.23, 95% CI=0.04-0.42, Z=2.42, p=0.015). We found that the combination of pedometers and the Internet has a significant positive effect on the daily step counts in patients with COPD. Further RCTs should be conducted to increase the sample size, enroll more outcome measures, extend the intervention duration, and monitor short-term and long-term effects.
