NEUROPLASTICITY, PAIN PERSISTENCE, AND REHABILITATION: A PHYSIOTHERAPY PERSPECTIVE

Abstract

Neuroplasticity is the fundamental capacity of the nervous system to alter its structure and function in response to experience, learning, damage, and healing. Through processes like peripheral and central sensitization, altered descending pain modulation, cortical reorganization, and neuroimmune interactions, maladaptive neuroplasticity changes contribute to the emergence and persistence of chronic pain, whereas adaptive neuroplasticity promotes healing and functional restoration. This chapter explores the impact of psychological, physical, behavioural, and environmental factors on neuroplasticity adaptability and gives a thorough description of the neurobiological mechanisms behind chronic pain. The evaluation of pain causes, functional performance, psychological aspects, and outcome measurements that inform tailored therapeutic decision-making are among the physiotherapy assessment techniques that are further covered. In order to encourage adaptive neuroplasticity, lessen pain, and enhance functional outcomes, evidence-based rehabilitation techniques such as pain neuroscience education, therapeutic exercise, motor control retraining, graded activity, graded motor imagery, mirror therapy, cognitive functional therapy, and technology-assisted rehabilitation are presented. Additionally, the chapter discusses new developments that have the potential to improve individualized physiotherapy care, including precision rehabilitation, biomarkers of neuroplasticity, artificial intelligence, virtual reality, and neuromodulation. Physiotherapists can apply mechanism-based, patient-centred rehabilitation techniques that maximize recovery, enhance quality of life, and support long-term pain management by having a thorough understanding of the connection between neuroplasticity and chronic pain.
