Physical activity is an important predictor for survival in patients with COPD. Wearable technology, such as pedometer or accelerometer, may offer an opportunity to quantify physical activity and evaluate related health benefits in these patients. To assess the performance of wearable technology in monitoring and improving physical activity in COPD patients from published studies. Literature search of Medline, Cochrane, Dare, Embase and PubMed databases was made to find relevant articles that used wearable technology to monitor physical activity in COPD patients. We identified 13 studies that used wearable technology, a pedometer or an accelerator, to monitor physical activity in COPD patients. Of these, six studies were randomized controlled trials (RCTs) which used the monitors as part of the intervention. Two studies reported the same outcomes and comparable units. They had measured the difference that the intervention makes on the number of steps taken daily by the patients. The results were highly heterogeneous with I=92%. The random-effects model gave an effect outcome on the number of steps taken daily of 1,821.01 [-282.71; 3,924.74] in favor of the wearable technology. Four of the 13 studies have reported technical issues with the use of the wearable technology, including high signal-to-noise ratio, memory storage problems and inaccuracy of counts. While other studies did not mention any technical issues, it is not clear whether these did not experience them or chose not to report them. Our literature search has shown that data on the use of wearable technology to monitor physical activity in COPD patients are limited by the small number of studies and their heterogeneous study design. Further research and better-designed RCTs are needed to provide reliable results before physical activity monitors can be implemented routinely for COPD patients.
身体活动是 COPD 患者生存的重要预测因素。可穿戴技术，如计步器或加速度计，可能为量化身体活动并评估这些患者的相关健康益处提供机会。评估可穿戴技术在监测和改善 COPD 患者身体活动方面的表现。对 Medline、Cochrane、Dare、Embase 和 PubMed 数据库进行文献检索，以查找使用可穿戴技术监测 COPD 患者身体活动的相关文章。我们确定了 13 项使用可穿戴技术、计步器或加速度计监测 COPD 患者身体活动的研究。其中，6 项研究为随机对照试验（RCT），使用监测器作为干预的一部分。两项研究报告了相同的结果和可比单位。他们测量了干预对患者每天步数的影响。结果高度异质，I=92%。随机效应模型给出了每日步数的干预效果为 1821.01[-282.71；3924.74]，有利于可穿戴技术。13 项研究中有 4 项报告了可穿戴技术使用中的技术问题，包括高信噪比、存储问题和计数不准确。虽然其他研究没有提到任何技术问题，但尚不清楚它们是否遇到了这些问题，还是选择不报告这些问题。我们的文献检索表明，可穿戴技术用于监测 COPD 患者身体活动的数据受到研究数量少和研究设计异质性的限制。需要进一步的研究和设计更好的 RCT，以提供可靠的结果，然后才能常规为 COPD 患者实施身体活动监测器。
