RPE-Based Exercise Prescription: Monitoring Intensity in Rehabilitation

What RPE adds

Rating of perceived exertion (RPE) captures how hard a task feels to the person. It can complement heart rate, workload, talk test, symptoms and movement quality—especially when beta-blockers, dysautonomia, pacing needs or equipment limits make a single target unreliable.

Choose one scale and explain its anchors. Borg 6–20 and CR10 are different scales; document which one is used and do not interchange their numbers.

Assessment and prescription

• Before exercise, review diagnosis, medical stability, medications, baseline capacity, pain, fatigue, falls risk and any condition-specific restrictions.
• Specify mode, frequency, intensity, duration, type and progression. A moderate aerobic effort often permits talking in phrases but not effortless singing; interpret this with the clinical context rather than as a universal rule.
• Use RPE to guide a tolerable starting dose, then cross-check symptoms, vitals when indicated, technique and recovery. For strength exercise, record load, repetitions, sets, effort and movement quality.

Progression and precautions

• Increase one variable at a time—often duration or repetitions before intensity—and reassess delayed fatigue and function. A session log can help identify patterns across days.
• Stop and assess chest pain, faintness, unusual breathlessness, new neurological symptoms or an unexpected physiological response. Condition-specific monitoring requirements take priority over a generic RPE target.
• Do not use RPE alone for people unable to report reliably or where the clinical condition requires objective monitoring.

Clinical summary

• RPE is a useful adjunct, not a replacement for clinical assessment.
• Specify the scale and its anchors; pair perceived effort with symptoms and objective measures as appropriate.
• Progress according to response and goals, not a fixed number alone.
