A High-Resolution Haptic Feedback Array (HRHFA) was developed and tested in its efficacy to communicate kinesthetic information relative to human gait. 7 able-bodied subjects were tasked with performing a knee motion tracking task given haptic guidance via the HRHFA affixed to their dominant forearm. Data was recorded via goniometer apparatus affixed to the subject's dominant leg, which provided measurements of knee angle, quadriceps and hamstrings EMG, and estimates of velocity and torque. It was found that the HRHFA offered a significant improvement over the control (p = 0.001). This demonstrates the efficacy with which HRHFA can communicate complex locomotor information.
