Final answer:
The primary treatment for moderate and severe rheumatoid arthritis involves rest, exercise, anti-inflammatory medications, corticosteroid injections, disease-modifying drugs, and possibly surgery depending on the extent of joint damage.
Step-by-step explanation:
The primary treatment strategies for individuals with moderate and severe rheumatoid arthritis (RA) are multifaceted and tailored to individual needs. In the early stages, treatment may include rest, use of a cane, or joint splints to minimize joint inflammation. Upon reduction of inflammation, exercise is recommended to strengthen surrounding muscles and maintain joint flexibility. When joint damage is more extensive, medications such as aspirin, topical pain relievers, and corticosteroid injections may be prescribed to relieve pain and decrease inflammation. Advanced cases of RA may require surgical intervention when joint damage is severe. Additionally, drugs that modify the disease process by targeting the immune response, such as reducing inflammatory cytokines or T cell activity, may be used to slow disease progression and manage symptoms.
