The Hand of Hope (HOH) therapy device is designed for neuromuscular rehabilitation of the hand and forearm, aiming to restore hand mobility through motor relearning. This device operates as a biofeedback system, utilizing surface electromyography (sEMG) sensors that detect the patient’s muscle signals to trigger their hand movements. These signals are then simplified and processed, and the patient receives visual feedback that encourages active engagement throughout the therapy session. The HOH offers a promising solution for patients seeking to regain hand mobility and function through targeted neuromuscular rehabilitation.
