Rating of perceived exertion (RPE), or the Borg scale, has been shown to be positively associated with physiologic effort in individuals undergoing cardiovascular assessment. This study examined the correlations between cardiovascular performance, psychosocial factors, and the RPE scale among 50 persons with chronic pain undergoing multidisciplinary assessment. The results indicated a significant negative association between fitness outcome measures (maximum VO2 and endurance on bicycle), psychosocial measures, and age. With a mean maximum heart rate achieved on the exercise bicycle of 79.2% (SD = 8.3), there was no significant association between the highest rating of perceived exertion on the exercise bicycle test and percent of maximum heart rate. Percent of maximum heart rate was significantly related to self-reported pain and disability as well as age. These findings suggest that perceived exertion in this population is not highly correlated with physiologic effort, as other factors such as pain may influence effort ratings.
自感用力度（RPE），即博格量表，已被证明与接受心血管评估的个体的生理努力呈正相关。本研究调查了50名接受多学科评估的慢性疼痛患者的心血管功能、心理社会因素与RPE量表之间的相关性。结果表明，体能结果指标（最大摄氧量和自行车耐力）、心理社会指标与年龄之间存在显著负相关。在运动自行车上达到的平均最大心率为79.2%（标准差=8.3），运动自行车测试中自感用力度的最高评分与最大心率百分比之间无显著关联。最大心率百分比与自我报告的疼痛和残疾以及年龄显著相关。这些发现表明，该人群的自感用力度与生理努力的相关性不高，因为疼痛等其他因素可能会影响用力程度评分。
