Title
3D Robotic Assessment of Proprioception for Up, Down, and Back Directions
Description
Background. Proprioception plays a large role in everyday functioning, involving both information of body position and movement (Johnson & Panayotis, 2010). Clinical assessments of proprioception are largely subjective and are not reliable measures for testing proprioception in impaired or unimpaired individuals. Recent advancements in technology and robotics have brought about new assessments that involve position matching and other paradigms. However, the results are confined to the horizontal plane and only look at a very small subset of human proprioceptive ability. Objective. The present study looks to overcome these limitations and examine differences in proprioceptive sensitivity across different directions in 3D space. Methods. Participants were recruited from Arizona State University to perform a "same-different" discrimination test using a robotic arm. Each participant was tested along two of the three directions, and within each direction, proprioception at four distances (1-4 cm) was tested. Performance was quantified using percent correct, d' analysis, and permutation testing on median and variance values. Results. Proprioceptive sensitivity was significantly greater in the up direction vs. down and back across all distances. The greatest difference in sensitivity occurred at 3 cm; permutation tests using median and variance values from percent correct and d' found statistical significance at this distance in the up vs. down and up vs. back comparisons. Conclusions. There is evidence that proprioceptive sensitivity is greater in an anti-gravity direction (up), in comparison to gravity-assisted or gravity-neutral (down and back) directions.
