Abstract Background In understanding how the human body perceives and responds to small slip-like motions information on how one senses the slip is essential. The effect of aging and plantar sensory loss on detection of a slip can also be studied. Using psychophysical procedures acceleration detection thresholds of small lateral whole-body perturbations were measured for healthy young adults HYA healthy older adults HOA and older adults with diabetic neuropathy DOA . It was hypothesized that young adults would require smaller accelerations than HOA s and DOA s to detect perturbations at a given displacement. Methods Acceleration detection thresholds to whole-body .
