A recent study that included 206 people indicates that people suffering from hip and knee arthritis benefit with regular exercise as well in combination with physical therapy. The average age of the group was 66 and it was noticed that the group that exercised and went in for physical therapy felt improvements in their physical functions over two years as against those who were given usual care.
The patients had knee X-rays taken and their symptoms were noted. After 2 months, they were categorized as having radiographic osteoarthritis (ROA) or symptomatic osteoarthritis (SOA). Those who jogged regularly displayed less SOA than those who did not engage in this activity.
