  The integration of technology into exercise regimens has emerged as a
strategy to enhance normal human capabilities and return human motor function
after injury or illness by enhancing motor learning and retention. Much
research has focused on how active devices, whether confined to a lab or made
into a wearable format, can apply forces at set times and conditions to
optimize the process of learning. However, the focus on active force production
often forces devices to either be confined to simple movements or
interventions. As such, in this paper, we investigate how passive device
behaviors can contribute to the process of motor learning by themselves. Our
approach involves using a wearable resistance (WR) device, which is outfitted
with elastic bands, to apply a force field that changes in response to a
person's movements while performing exercises. We develop a method to measure
the produced forces from the device without impeding the function and we
characterize the device's force generation abilities. We then present a study
assessing the impact of the WR device on motor learning of proper squat form
compared to visual or no feedback. Biometrics such as knee and hip angles were
used to monitor and assess subject performance. Our findings indicate that the
force fields produced while training with the WR device can improve performance
in full-body exercises similarly to a more direct visual feedback mechanism,
though the improvement is not consistent across all performance metrics.
Through our research, we contribute important insights into the application of
passive wearable resistance technology in practical exercise settings.
