When dealing with arthritis, a physical therapist would focus on managing pain, preserving joint function, and improving overall mobility. Treatment may include a combination of gentle exercises to maintain joint flexibility, strength training to support the affected joints, and low-impact aerobic activities. The therapist may use modalities like heat or cold therapy for symptom relief and educate the individual on joint protection techniques. Additionally, lifestyle modifications and assistive devices might be recommended to enhance daily functioning while minimizing stress on arthritic joints.
