One of the most persistent myths the Pinnacle Physiotherapy team encounters is that people with arthritis should rest and avoid activity to protect their joints. In fact, the opposite is true: appropriate, regular movement is one of the most effective tools available for managing arthritis pain and slowing its progression.

What is arthritis?

Arthritis is a broad term covering more than 100 conditions affecting the joints. The two most common forms are:

  • Osteoarthritis (OA): A degenerative condition in which the cartilage cushioning the joint surfaces gradually wears down. It most commonly affects the knees, hips, hands, and spine.
  • Rheumatoid arthritis (RA): An autoimmune condition in which the body's immune system attacks the joint lining (synovium), causing inflammation, pain, and over time, joint damage.

Why exercise helps

Cartilage has no direct blood supply — it receives its nutrition through the compression and decompression that occurs with movement. Regular activity literally feeds the cartilage. Beyond that, strengthening the muscles around an arthritic joint reduces the load the joint itself has to bear, which directly reduces pain.

Exercise also improves joint lubrication, reduces systemic inflammation, supports healthy weight, and improves mood and sleep — all of which influence how you experience arthritis symptoms day to day.

What types of exercise are best?

Low-impact aerobic activity

Walking, swimming, cycling, and water aerobics are all excellent choices. They raise your heart rate and improve cardiovascular health without the high impact forces that can aggravate inflamed joints.

Strength training

Building strength in the muscles surrounding affected joints is one of the most impactful things you can do. For knee OA in particular, quadriceps strength is strongly linked to pain levels and function. Resistance training two to three times per week is well supported by the evidence.

Flexibility and range of motion

Gentle stretching and range-of-motion exercises help maintain joint mobility and reduce stiffness. These are particularly useful in the morning, when joints tend to feel their most rigid.

Getting started safely

The key is starting gradually and progressing sensibly. Some discomfort during or after exercise is normal when you're getting started, but sharp pain or swelling that persists for more than an hour after exercise is a signal to ease back and reassess.

At Pinnacle Physiotherapy, we work with many patients living with arthritis to develop safe, effective exercise programs tailored to their specific joints, fitness level, and lifestyle. If arthritis is limiting what you can do, come and see us in Windsor, LaSalle, or Lakeshore — we'd love to help you move better.
