Abstract: Objective To discuss the relationship between heart rate (HR), rate of perceived exertion (RPE) and oxygen consumption in therapeutic exercises for stroke patients. Methods Eighteen stroke patients a-ble to walk independently participated in the test. K4b2 Pulmonary Function Equipment was used to record their heart Rates(min-1)and specific oxygen consumption(ml·min-1·kg-1)during the following exercises:relaxed sitting,sit-to-stand transfers, leaning against a wall and elevating the hips (strength training of the gluteus maximus) , raising the unaffected leg while the affected leg is weight bearing, raising the affected leg while the unaffected leg is weight bearing, climbing up and down stairs, and walking 60 meters. RPE was surveyed after each exercise. Results The correlation between HR and oxygen consumption was moderate (r = 0.618, P≤0.001), but it was weak between RPE and oxygen consumption (r = 0.325 ,P≤0.001). Conclusion Heart rate is a better index than RPE for eval-uating exercise intensity with stroke patients able to walk independently.
