3.6. Hand of HopeThe Hand of Hope (Rehab-Robotics, Hong Kong) is a semi-wearablehand exoskeletal device.The Hand of Hope utilizes a biofeedback approach, detecting a user’s intent through surface electromyography and responding with exoskeleton-driven grasp or release. In a study of ten subjects with chronic stroke, a training program using the Hand of Hope resulted in statistically significant improvements in functional performance as well as enhanced muscle coordination, as measured by EMG (Hu et al., 2013).
