Introduction: Chronic lumbar musculoskeletal pain is a disabling condition that affects a significant number of individuals, leading to decreased functionality and reduced quality of life. Medical rehabilitation, employing a range of kinetic techniques, has emerged as a potential intervention for managing chronic lower back pain. This case report focuses on evaluating the impact of medical rehabilitation utilizing kinetic techniques on patients with chronic lumbar musculoskeletal pain Methods: A 46-year-old male patient with a history of chronic lumbar musculoskeletal pain was enrolled in a 2-week medical rehabilitation program. The program incorporated a variety of kinetic techniques, including Williams and Jacobson techniques along with TENS. Pain levels were assessed using a visual analog scale (VAS), and functional capacity was evaluated through the Oswestry Disability Index (ODI) Results: Considering the risk of atrial fibrillation and another cardiovascular comorbidity the patient was directed to a rehabilitation treatment plan, along with pharmaceutical interventions that included nonsteroid anti-inflammation, and myorelaxant drugs. Following the 2-week rehabilitation program, the patient reported a significant reduction in pain intensity, with the VAS score decreasing from 8/10 to 3/10. The ODI score showed a notable improvement in functional capacity, decreasing from 58% to 32%. Conclusion: Medical rehabilitation incorporating kinetic techniques demonstrated a positive impact on a patient with chronic lumbar musculoskeletal pain. The comprehensive rehabilitation program led to a significant reduction in pain intensity, improved functional capacity, and enhanced quality of life outcomes.
