Scholl’s researchers for the first time demonstrated a potential deficit in postural compensatory strategy in DPN patients

In a recent study published in the Journal of Diabetes Science and Technology entitled ‘Assessing Postural Control and Postural Control Strategy in Diabetic Patients Using Innovative and Wearable Technology’, Scholl’s CLEAR researchers explored postural control and postural compensatory strategy (PCS) in 17 patients with diabetic peripheral neuropathy (DPN) and 21 healthy subjects. This study suggests a novel index that allows quantifying PCS performance (i.e. anticipatory strategy to compensate movement of the proximal segment by movement of the distal segment). Clinical results of this investigation suggest that alteration in somatosensory/proprioception feedback due to DPN will significantly impact postural reciprocal coordination between ankle and hip joints movements. Additionally, in DPN subjects, closing the eyes diminished this coordination, which is used by healthy subjects to anticipate motion of the proximal segment by motion of the distal segment. This compensatory strategy in healthy subjects allows them to reduce the variation of center of mass during both voluntary and involuntary movements. Deterioration in PCS in a DPN subject may make him or her vulnerable in maintaining balance while closing the eyes or in face of high amplitude of sway for either proximal or distal segments. This important study is a fruit of a student summer research study lead by Dr Najafi (lead author) and a Scholl’12 student, Mrs Deena Horn (second author).
