Read full description

Phantom Rehab is a comprehensive therapy application designed to help individuals manage and reduce phantom limb pain through the scientifically-backed Graded Motor Imagery (GMI) approach. Disclaimer: Phantom Rehab is intended to be used as a supportive tool for rehabilitation. It is not a substitute for professional medical advice, diagnosis, or treatment. Always consult with your doctor or qualified healthcare provider before starting this program or making any medical decisions. The app guides users through a structured three-step rehabilitation process: 1. Laterality Training: Practice identifying left and right body parts to improve body awareness while being timed for efficiency and accuracy. 2. Motor Training: Progress to imagining pain-free movements of the affected body part, starting with simple motions and advancing to more complex ones. The app provides videos of others performing movements for users who find imagining movements difficult initially. 3. Mirror Training: Utilize your device's camera as a mirror to create the illusion that your unaffected limb is actually your affected limb, engaging mirror neurons to help rewire neural pathways. For optimal results, the app should be used according to the recommended schedule: • Laterality: 5 minutes, 5 times daily • Motor Imagery: 2 hours daily for at least 2 weeks • Mirror Therapy: 20 minutes daily until symptom-free Term of Use: https: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
