“…This is most likely a result of human synaptic delay and reaction time. For example, [20] found that the reaction time from tactile stimuli in the right big toe was approximately 0.25 s. This means that to truly avoid overshoot of a target load, the vibrotactile feedback must be initiated somewhat earlier than the target load depending on the rate of loading.…”

Accurate partial weight bearing in the foot during rehabilitation from musculoskeletal injuries in lower extremities is important to ensure successful recovery. However, it is difficult for patients to know how much to load, and many are therefore reluctant to load at all. This study presents a novel footwear concept with strain gauge based force sensors and vibrotactile feedback that enables accurate foot loading and partial weight bearing monitoring during rehabilitation from musculoskeletal injuries in the lower extremities. Four force sensors integrated in the foot-sole of a sandal measures ground reaction force, and two eccentric rotating mass motors provide vibrotactile feedback to the user when a predetermined force threshold is reached. Partial weight bearing data from the force sensors are transferred wireless using wifi communication to a remote patient monitoring dashboard, enabling decision support for health personnel. We demonstrate the use of the prototype to reduce overloading in partial weight bearing in a validation experiment (N = 16). Findings showed that the prototype significantly reduced overloading in the right foot for healthy adults (p < 0.05), which indicate that closed-loop force sensing footwear with vibrotactile feedback can be useful in aiding patients with musculoskeletal injuries in the lower extremities during rehabilitation.

The last three decades have seen major strides in our understanding of neural mechanisms of high-level vision, or visual cognition of the world around us. Vision has also served as a model system for the study of brain function. Several broad insights, as yet incomplete, have recently emerged. First, visual perception is best understood not as an end unto itself, but as a sensory process that subserves the animal's behavioral goal at hand. Visual perception is likely to be simply a side effect that reflects the readout of visual information processing that leads to behavior. Second, the brain is essentially a probabilistic computational system that produces behaviors by collectively evaluating, not necessarily consciously or always optimally, the available information about the outside world received from the senses, the behavioral goals, prior knowledge about the world, and possible risks and benefits of a given behavior. Vision plays a prominent role in the overall functioning of the brain providing the lion's share of information about the outside world. Third, the visual system does not function in isolation, but rather interacts actively and reciprocally with other brain systems, including other sensory faculties. Finally, various regions of the visual system process information not in a strict hierarchical manner, but as parts of various dynamic brain-wide networks, collectively referred to as the "connectome." Thus, a full understanding of vision will ultimately entail understanding, in granular, quantitative detail, various aspects of dynamic brain networks that use visual sensory information to produce behavior under real-world conditions. © 2017 American Physiological Society.
