目的：为了评估主观量表，视觉模拟量表（VAS），博格CR 10（博格）量表，或李克特量表（LS），如果有的话，是决定性的更可重复性和敏感性的变化，在症状的评估。设计：前瞻性临床研究。设置：运动实验室。参与者：23个体力活动的男性科目（平均值+/- SD年龄30 +/- 4岁）被招募。干预：每个科目参加了四次运动实验室，间隔1周。使用了三种主观量表：（1）VAS（连续量表）;（2）博格量表（12个固定点）;和（3）李克特量表（LS; 5个固定点）。进行了四次相同的次最大试验（2分钟，60%最大摄氧量[（V）超过点O（2）max]，6分钟，70%（V）超过点O（2）max）。进行了两项测试，以评估每个主观量表获得的分数的再现性。进行了另外两项试验，以评估每个量表对症状感知变化的敏感性：普萘洛尔80 mg双盲治疗（即，积极治疗;增加运动期间呼吸困难和全身疲劳的感觉）或匹配安慰剂。在运动1 min 30 s、5 min 30 s和7 min 15 s时测量主观量表评分。重现性定义为受试者间方差解释的总方差（受试者间加受试者内方差）的比例（以百分比表示）。敏感性被定义为活性药物治疗的效果超过了受试者内的变化。结果：总体而言，VAS表现最好的呼吸困难和全身疲劳的再现性方面，再现系数高达78%。对于敏感性，VAS对呼吸困难最敏感（比率，2.7），而博格量表对全身疲劳最敏感（比率，3.0）。心理和生理变量之间的关系在整个测试过程中相当稳定，总体典型相关系数为0.73 ~ 0.82。结论：本研究表明，主观量表可以重复性地测量稳态运动中的症状，并可以检测药物干预的效果。VAS和博格量表似乎是用于此目的的最佳主观量表。
Objective: To assess which subjective scale, the visual analogue scale (VAS), the Borg CR10 (Borg) scale, or the Likert scale (LS), if any, is decidedly more reproducible and sensitive to change in the assessment of symptoms.Design: Prospective clinical study.Setting: Exercise laboratory.Participants: Twenty-three physically active male subjects (mean +/- SD age of 30 +/- 4 years old) were recruited.Intervention: Each subject attended the exercise laboratory on four occasions at intervals of 1 week. Three subjective scales were used: (1) the VAS (continuous scale); (2) the Borg scale (12 fixed points); and (3) the Likert scale (LS; 5 fixed points). Four identical submaximal tests were given (2 min at 60% maximum oxygen uptake [(V)over dot O(2)max] and 6 min at 70% (V)over dot O(2)max). Two tests were undertaken to assess the reproducibility of scores that were obtained with each subjective scale. Two other tests were undertaken to assess the sensitivity of each scale to a change in symptom perception: a double-blind treatment with propranolol, 80 mg, (ie, active therapy; to increase the sensation of breathlessness and general fatigue during exercise) or matching placebo. The subjective scale scores were measured at 1 min 30 s, 5 min 30 s, and 7 min 15 s of exercise. Reproducibility was defined as the proportion of total variance tie, between-subject plus within-subject variance) explained by the between-subject variance given as a percentage. Sensitvity was defined as the effect of the active drug therapy over the variation within subjects.Results: Overall, the VAS performed best in terms of reproducibility for breathlessness and general fatigue, with reproducibility coefficients as high as 78%. For sensitivity the VAS nas best for breathlessness (ratio, 2.7) and the Borg scale was most sensitive for general fatigue (ratio, 3.0). The relationships between the respective psychological and physiologic variables were reasonably stable throughout the testing procedure, with overall typical correlations of 0.73 to 0.82.Conclusion: This study suggests that subjective scales can reproducibility measure symptoms during steady-state exercise and can detect the effect of a drug intervention. The VAS and Borg scales appear to be the best subjective scales for this purpose.
