  • Ankle Pumps: While seated, flex and point your toes for 5-10 minutes. This exercise helps improve blood circulation to the joints.

Strengthening Exercises:

  • Straight Leg Raises: Lie on your back with your legs extended. Lift your affected leg about 6 inches off the floor and hold for a few seconds. Repeat for 10-15 times for each leg.
  • Wall Slides: Stand with your back against the wall, feet shoulder-width apart. Slowly slide down the wall into a seated position and then return to a standing position. Perform 2-3 sets of 10-15 repetitions.
  • Seated Quadriceps Contractions: Sit with your legs extended. Tighten the quadriceps muscles and hold for a few seconds. Perform 2-3 sets of 10-15 repetitions.

Aerobic Exercises:

  • Water Aerobics: Aquatic exercises in a pool are often recommended for individuals with knee RA. Water provides resistance while being easy on the joints. Try activities like water walking or gentle swimming for 20-30 minutes per session, a few times a week.

Balance and Coordination Exercises:

  • Single Leg Stance: Stand on one leg while holding onto a stable surface for support. Try to maintain your balance for 20-30 seconds, then switch to the other leg. Perform 2-3 sets for each leg.
