Neural Mobilization to Improve Chronic Musculoskeletal Pain in Older Adults

The goal of this clinical trial is to discover whether performing active neural mobilization exercises works to manage chronic musculoskeletal pain in older adults. The main question it aims to answer is: Can an active neural mobilization program improve pain intensity and functional capacity? Participants will: * Perform active neural mobilization exercises for 8 weeks (twice a week), under the in-person supervision of a physiotherapist; * Visit the clinic twice a week for 9 to 12 weeks for consultations, examinations, and symptom monitoring; * Keep a diary of their symptoms and frequency of analgesic use.
