Effect of Motorized Scooters on Quality of Life and Cardiovascular Risk

摘要

Physical inactivity increases cardiovascular risk. The possible adverse effects of regular motorized scooter use, recently popularized for patients with physical limitations, has not been previously examined. We performed a single-center, retrospective cohort study of 102 consecutive patients who had obtained medical approval for, and subsequently received, a motorized scooter during a 6-year period. The clinical data were collected for the 12 months before and after the intervention. Surveys assessing 11 different facets of health-related quality of life were returned by 28% of patients. The patients receiving a scooter were 68 + or - 19 years old, and 55% were women. The medical indications for scooter use, by decreasing frequency, were disabling arthritis, chronic lung disease, neurologic disorders, and heart failure. Patients returning the surveys estimated scooter use at a median of 4 hours/day, with walking confined to 30 min/day. Despite significant physical and psychological improvements in all quality-of-life categories.
