Neuromodulation of Central Sensory Integration to Improve Postural Control

Sensory integration required for balance will be measured using the sensory organization test which includes six conditions in which visual and proprioceptive sensory cues are sequentially referenced (i.e. reduced) to stress available sensory information and sensory integration for postural control. Performance on the sensory organization test has been correlated with falls and successful response to balance perturbation. Balance performance will be evaluated by postural sway. Cognitive function will be assessed using the NIH toolbox with a focus on executive function. tDCS will be used to modify PFC excitability and measure its immediate after-effect on balance performance while performing the sensory organization test in OTTBCS. CIPN severity will be evaluated using measurements of distal proprioception. The study sample will be older breast cancer survivors (n=20) diagnosed and treated with taxane chemotherapy after the age of 60 years to avoid heterogeneity due to multiple cancer types, treatments, and sexes. Outcome measure were removed. Remaining outcome measures were ones that were assessed both before and after tDCS.
