I'm two months out after a total knee replacement. I've been using an electronic pedometer to monitor my activity. I'd like to figure out how active I am. Is there any kind of scale to help me out?

A study done by researchers at the Joint Replacement Institute in Los Angeles, California, used the following guidelines to calculate activity level. This may help you:

  • Inactive 0 to 5,000 steps/day
  • Low activity 5,001 to 10,000 steps/day
  • Moderate activity 10,001 to 15,000 steps/day
  • High activity 15,001 to 20,000 steps/day
  • Extreme activity 20,001+ steps/day

    You don't really have to measure every single day for the rest of your life. Their study showed that a four-day sample is long enough to give you an idea of your overall activity level.

    You may want to recheck your results three or four times a year. This will account for seasonal changes. Repeating the study over the years will also give you some long-term calculations. This is especially helpful if you change your activity level over time.
