Does strength training help with arthritis pain in older adults?
My mother is 69 with knee osteoarthritis and has been told to rest and avoid straining her knees. But she is getting weaker and the pain is not better. Is strength training safe and helpful for arthritis, or does it make joint damage worse?
✓ Accepted answer
Yes, strength training is safe and highly effective for reducing arthritis pain and improving function in older adults.
- It does not damage joints: Modern rheumatology research, supported by organizations like the Arthritis Foundation, confirms that low-impact resistance training strengthens the muscles surrounding the joint. This acts like a padded brace, significantly offloading pressure from the knee cartilage without causing structural harm.
- Addressing the 'rest' advice: While rest is appropriate during acute flare-ups, prolonged inactivity is the enemy of osteoarthritis. Weak thigh muscles (quadriceps and hamstrings) actually increase the load on the knee joint with every step. Strengthening these muscles is one of the few treatments proven to reduce both pain and the need for surgery.
- Safety first: Start with low-resistance exercises, such as seated leg extensions, wall sits, or water aerobics, which minimize joint stress. A physical therapist can design a program tailored to her specific pain levels. If she experiences sharp pain (not just muscle soreness) during an exercise, she should stop and modify the movement.
- Consistency is key: The American Geriatric Society recommends engaging in muscle-strengthening activities two or more days per week. Even short, 10-minute sessions can begin to build the necessary support. This approach is backed by extensive clinical trials showing that regular strength training can improve a patient's ability to walk and climb stairs, directly combating the weakness your mother is currently experiencing.
Reassure your mother that moving strategically is far more beneficial than resting in bed. A doctor can clear her for a specific regimen, ensuring she progresses safely toward a more active and comfortable daily life.
