MIRROR THERAPY IN PHYSIOTHERAPY Mirror therapy is a rehabilitation technique that utilizes visual feedback to improve motor function and alleviate pain in individuals with neurological and musculoskeletal conditions. It involves using a mirror to create the illusion of movement in an affected limb by reflecting the image of the unaffected limb. This visual illusion tricks the brain into perceiving movement in the affected limb, which can stimulate neural activity and promote recovery. MECHANISM OF ACTION Mirror therapy, also known as mirror visual feedback therapy, is a non-invasive rehabilitation technique that involves the use of mirrors to create the illusion of movement in a limb that is affected by injury or dysfunction. Originally developed as a treatment for phantom limb pain in amputees, mirror therapy has since been adapted and applied to a wide range of conditions, including stroke, Complex Regional Pain Syndrome (CRPS) and musculoskeletal injuries. The underlying principle of mirror therapy lies in the brain’s ability to reorganize and adapt in response to sensory input, a phenomenon known as neuroplasticity. By providing visual feedback that contradicts the sensory information received from the affected limb, mirror therapy can help rewire the brain’s neural circuits, modulate pain perception and improve motor control and function.CLINICAL APPLICATIONSThe mechanism of action behind mirror therapy involves the brain's neuroplasticity, its ability to adapt and reorganize in response to sensory input. When a patient views the reflection of their unaffected limb in a mirror, the brain perceives this as the movement of the affected limb.This visual feedback stimulates the motor pathways and activates the corresponding areas of the brain, promoting neural activity and potentially improving motor control. BENEFITS OF MIRROR THERAPY • Phantom Limb Pain: Mirror therapy can help reduce pain and improve the quality of life for amputees by providing visual feedback that suggests movement in the phantom limb. • Stroke Rehabilitation: Mirror therapy can improve motor function, range of motion, and functional independence in stroke patients, particularly those with upper limb hemiparesis or hemiplegia. • Complex Regional Pain Syndrome (CRPS): Mirror therapy can reduce pain and improve function in individuals with CRPS by modulating pain perception and promoting desensitization. • Musculoskeletal Injuries: Mirror therapy can be used as an adjunctive therapy to accelerate recovery, improve joint range of motion, and enhance proprioception and motor control in injured limbs. Considerations • Pain Relief: It can reduce pain intensity and frequency in chronic pain conditions like phantom limb pain and CRPS. • Improved Motor Function: It can enhance motor function, range of motion, and coordination in neurological conditions such as stroke and traumatic brain injury. • Enhanced Proprioception: It can improve the sense of body position and movement in individuals with musculoskeletal injuries and neurological deficits. Mirror therapy may be beneficial in increasing the balance ability of subacute stroke patients.[1] While mirror therapy offers numerous benefits, it's essential to consider potential drawbacks. Some patients may experience emotional distress or find the therapy challenging. The effectiveness of mirror therapy can also vary depending on the individual and the specific condition.
