Mirror Therapy - Applications, Practical Considerations, and Contraindications

Introduction

Mirror therapy is a type of neurorehabilitation technique that helps in enhancing motor recovery and helps in reducing pain in patients with different neurological conditions, especially individuals with limb paralysis or amputation. In this therapy, there is a usage of mirrors which help in creating an illusion of movement and give visual feedback to the brain, which will help in rewiring the neural pathways and help in improving motor function. Mirror therapy is used in rehabilitation after complex regional pain syndrome, phantom limb pain, stroke, and other neurological disorders which involve reduced motor function.

What Are the Applications of Mirror Therapy?

The applications of mirror therapy in the rehabilitation process of patients with different medical conditions include the following:

• Stroke Rehabilitation - Mirror therapy is used in the recovery process after a stroke to recover motor function and decrease the pain in the patients. With the help of visual feedback, the motor areas present in the brain are stimulated, which helps in improving movement and limb coordination.

• Phantom Limb Pain - Mirror therapy helps in reducing phantom limb pain. It is a type of discomfort or pain experienced in an amputated limb. With the help of mirror therapy, an illusion of a complete limb is created, which will reduce the perception of pain.

• Complex Regional Pain Syndrome - A chronic pain condition that affects a leg or an arm after a trauma or injury is called complex regional pain syndrome. Mirror therapy helps in decreasing the pain, increasing the range of motion, and increasing the function in patients with complex regional pain syndrome by retraining the brain and also desensitizing the limb which is affected by the pain.

• Motor Rehabilitation - Mirror therapy helps in the rehabilitation of motor impairment resulting from different medical conditions like orthopedic injuries, musculoskeletal conditions, and neurological disorders. It helps in improving motor control and coordination and also helps in controlling the movement patterns by giving visual feedback, which helps in activating the neural pathway.

• Prosthetic Training - Mirror therapy helps patients to assist in adapting and using a prosthetic limb. With the help of mirror therapy, an illusion is created of a functioning limb which helps in visualizing and practicing movement with the help of a prosthesis. It helps increase coordination and improve the integration of prosthetic limbs into day-to-day activities.

How Does Mirror Therapy Work?

Mirror therapy works by three factors, including visual feedback, neuroplasticity of the brain, and principles of mirror neurons. Neuroplasticity is the ability of the brain to reorganize itself to form new neural connections. With the help of mirror therapy, the patient can observe the unaffected limb in the mirror. This will activate the motor area present in the brain and simulate the experience of movement in the affected leg. This will help rewire the brain and strengthen the different neural pathways for movement and sensation. The mirror will create a visual illusion that will trick the brain cells into moving and giving feedback to the affected limb. When movements are done with an unaffected limb, the mirror will reflect the image, which helps in giving a visual illusion to the brain and gives an impression that the affected limb is moving. It will help in giving a sense of movement.

What Are the Practical Considerations in Mirror Therapy?

Some of the practical considerations taken care of in mirror therapy include the following:

• The mirror should be placed in a position such that it will give a clear reflection of the unaffected limb. The placement of mirrors is important in creating an accurate visual illusion and will improve the effectiveness of therapy.

• Sufficient or adequate lighting is important to visualize the reflection in the mirror. Good lighting conditions help in giving visual feedback and will avoid discomfort or visual strain during the therapy.

• The patients should be comfortably positioned in front of the mirror. It helps in maintaining the alignment of the body to prevent strain and discomfort during the therapy session.

• Safety precautions are necessary during this therapy, depending on the patient's condition.

• The therapy will be gradually progressing, and the intensity or difficulty will be increased depending on the improvement in the individual's condition.

• Consistency in practicing the exercise is important to give an optimal result.

• The effectiveness and progression of mirror therapy will be regularly evaluated and monitored by therapists.

What Are the Potential Benefits and Outcomes of Mirror Therapy?

The potential benefits and outcomes of mirror therapy include the following:

• Reduction in pain.

• Increased motor function.

• Improved range of motion.

• Improved motor control and coordination.

• Functional improvement.

• Psychological well-being.

What Are the Precautions and Contraindications of Mirror Therapy?

Some of the precautions and contraindications of mirror therapy include the following:

• Mirror therapy includes visual illusion and can reduce discomfort and emotions in some patients. In people with psychological problems like anxiety disorders, severe depression, or body dysmorphic disorders, this therapy is not indicated without any psychological support.

• Mirror therapy needs cognitive functioning and attention in order to follow instructions and engage in the therapy. Patients with severe cognitive impairments or people having difficulty understanding or participating in this therapy do not get any benefit from this process.

• Mirror therapy includes exercises and movement of the affected limb. In case of unhealed wounds, infections, or open sores in the affected region, mirror therapy should be postponed till the wound is properly healed to avoid further complications.

• Mirror therapy includes visual stimulations. In patients with photosensitive epilepsy, it can trigger seizures. So in patients with photosensitivity epilepsy, it is important to consult a healthcare professional before engaging in mirror therapy.

• Some people can experience dizziness, discomfort, and increased pain during therapy. In this case, it is important to communicate with a medical professional.

Conclusion

In conclusion, mirror therapy is a neurorehabilitation method that helps patients with neurological conditions like limb paralysis, stroke, and phantom limb pain to improve their potential. By using the brain's plasticity, visual feedback is given through a mirror, which helps rewire the neural pathways and will increase motor function, reduce pain and improve the range of motion. The effectiveness of mirror therapy can range from person to person, and it is not suitable for everyone.
