Abstract

The intensity of breathlessness in normal subjects during exercise was measured on seven occasions over a 40-week study period to assess the long-term repeatability of Borg scale estimates of breathlessness. 2. In all subjects there was a significant correlation (P = 0.0001) between breathlessness and minute ventilation. Minute ventilation measured at each work rate did not differ between the seven exercise tests (P greater than 0.05). 3. There was no significant difference between the mean Borg scores (measured with respect to a given level of ventilation) in 5 of the 7 test weeks (P greater than 0.05). The slope of the relationship Borg score/minute ventilation did not differ between the seven exercise tests (P greater than 0.05). 4. Breathlessness estimation was highly reproducible both after 1 week and after 40 weeks of the study (both P greater than 0.05). 5. The duration without testing between consecutive tests did not affect reproducibility: the mean Borg score was as equally reproducible after an interval of 22 weeks without testing as after an interval of 1 week (P greater than 0.05). 6. The Borg scale provides a reliable technique for studying the sensation of breathlessness over extended time periods.

摘要

在一项为期40周的研究期间，对正常受试者运动时的呼吸困难强度进行了7次测量，以评估Borg量表对呼吸困难估计的长期可重复性。2. 在所有受试者中，呼吸困难与分钟通气量之间存在显著相关性（P = 0.0001）。在每个工作率下测量的分钟通气量在7次运动测试之间没有差异（P>0.05）。3. 在7个测试周中的5周内，平均Borg评分（相对于给定的通气水平进行测量）之间没有显著差异（P>0.05）。7次运动测试之间，Borg评分/分钟通气量关系的斜率没有差异（P>0.05）。4. 在研究的1周后和40周后，呼吸困难估计都具有高度可重复性（两者P>0.05）。5. 连续测试之间未进行测试的持续时间不影响可重复性：在间隔22周未进行测试后，平均Borg评分与间隔1周后一样具有同等的可重复性（P>0.05）。6. Borg量表为研究长时间内的呼吸困难感觉提供了一种可靠的技术。
