Osteoarthritis and Exercise

Physical Examination Findings

The results of Marie's fitness evaluation at the first visit and after 18 months of regular exercise are summarized in the following table.

It is important to recognize the significant decrease in blood pressure, weight, timed-stands test, and the 50 foot walk test, as well as the increase in VO2 max. Blood pressure is an excellent indicator of how hard the heart is working. It is a way to monitor the improvement in cardiovascular fitness. We can expect that with exercise, the heart will become stronger and more efficient. An increase in VO2 max is a measure of oxygen uptake during exercise. Marie's VO2 max improved drastically, from an average score to a rating of excellent.

The other significant improvements in Marie's fitness over the past 12 months is reflected in her timed-stands test scores and her 50 foot walk scores. The timed-stands tests consists of standing up from a sitting position and back down 10 times. This test measures leg and hip power and endurance. Marie's time decreased by almost two-thirds, indicating a large increase in lower extremity strength. The 50 foot walk test looks at the number of seconds it takes a person to walk 50 feet. Ideally, under 10 seconds ensures safety when doing activities such as crossing the street. Again, Marie's time decreased, indicating an increase in lower extremity endurance.
