- Tighten the muscle at the front of your thigh by pushing your knee down towards the floor.
- Hold for 5 seconds and then relax.
- Repeat 10-15 times, and then switch to the other leg.
Regularly performing quad sets can help to improve the strength of your quadriceps and contribute to better knee function.
Straight Leg Raises
Straight leg raises can help to strengthen your quadriceps and hip muscles without putting pressure on your knee joint. This can be particularly beneficial for individuals with knee osteoarthritis.
To perform a straight leg raise:
- Lie down with one leg bent at the knee and the other leg straight.
- Keeping your straight leg on the floor, tighten the muscles at the front of your thigh and lift your leg about a foot off the ground.
- Hold for a few seconds, then slowly lower your leg back to the floor.
- Repeat 10-15 times, and then switch to the other leg.
Incorporating straight leg raises into your exercise routine can help to improve muscle strength and joint stability, which can contribute to better management of knee osteoarthritis. Remember, it's important to perform these exercises regularly and consistently for optimal results. Consult a healthcare professional to ensure these exercises are suitable for you and to receive personalized advice based on your condition.
Additional Physiotherapy Exercises
In addition to hamstring stretches, quad sets, and straight leg raises, there are other beneficial physiotherapy exercises for knee osteoarthritis. By incorporating a variety of exercises into your routine, you can effectively improve flexibility, muscle strength, balance, and mobility [2]. Here are three additional exercises that are particularly helpful.
Calf Stretches
Calf stretches are an effective exercise for individuals with knee osteoarthritis. These stretches can help improve flexibility and relieve tension in the calf muscles, which can in turn alleviate discomfort in the knee joint. To perform calf stretches, stand at arm's length from a wall, placing your hands on the wall for support. Step back with one foot, keeping that leg straight and the heel on the ground. Bend the other knee and lean forward until you feel a stretch in the calf of the straight leg. Hold the stretch for 15-30 seconds and repeat with the other leg. (Sheltering Arms Institute)
Seated Hip Marches
Seated hip marches are another beneficial exercise for knee osteoarthritis. These exercises can help improve knee strength, range of motion, and stability. To perform seated hip marches, sit on a chair with your feet flat on the floor. Slowly lift one foot off the floor, keeping your knee bent. Lower your foot back to the floor and repeat with the other leg. Aim for 10-15 repetitions with each leg. (Sheltering Arms Institute)
Pillow Squeezes
Pillow squeezes are another exercise that can help improve knee strength and stability for individuals with knee osteoarthritis. To perform pillow squeezes, sit on a chair with your feet flat on the floor and place a pillow between your knees. Squeeze the pillow with your knees, hold for 5 seconds, and then relax. Aim for 10-15 repetitions. (Sheltering Arms Institute)
By incorporating these exercises into your physiotherapy routine, you can effectively manage symptoms of knee osteoarthritis and improve your overall knee health. It's important to remember that consistency is key when it comes to physiotherapy exercises. Regular practice can help maintain flexibility, strength, balance, and stability in the knees.
