Reduced customary activity in chronic heart failure: assessment with a new shoe-mounted pedometer

Int J Cardiol. 1994 Jan;43(1):39-42. doi: 10.1016/0167-5273(94)90088-4.


Although many methods exist to assess the degree of incapacity of patients with chronic heart failure during normal daily activities, all have their limitations. In this study we describe a new shoe-mounted pedometer and compare it with body worn pedometers in normal volunteers and in patients with chronic heart failure. Ten young normal healthy volunteers participated in a comparison of the new shoe-mounted device with body born pedometers and counting a direct footfall. Seventeen patients with chronic heart failure and 10 aged-matched healthy elderly subjects participated in a comparison of both pedometers over 7 days. In the young volunteers the shoe-mounted pedometers were more accurate than the body-borne devices. With both pedometers the patients with chronic heart failure had a reduced level of activity compared with the normal volunteers over the 1 week period (P = 0.01). In both the patients and volunteers the shoe-mounted device recorded a higher score than the body borne pedometers (P < 0.01). The electronic shoe mounted pedometers are a more accurate way of assessing customary activity. In patients with chronic heart failure customary activity is substantially reduced compared with fit healthy elderly subjects.
