Dynamic and isometric knee exercises are equally effective in reducing pain in people with osteoarthritis (OA) of the knee, US research shows.
The researchers randomly assigned 102 people with knee OA to knee strengthening with dynamic exercises across a functional range of motion, to isometric exercises at discrete joint angles, and to a control group.
Knee strengthening exercises performed three times a week for 16 weeks helped people with knee OA to use stairs and get up from the floor more quickly with less pain than had been possible before they started the programme.
The improvement in knee pain and function was similar for both types of exercise, but no improvement in pain or function was seen in the control group (Archives of Physical Medicine and Rehabilitation 2002; 83: 1187-95).
