Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The sensory intervention is based on previous work (Hillier and Dunsford 2006, Lynch et al 2007) and incorporates in each training session a hierarchy of tasks starting with general education about sensation, how it can become altered and the functional consequences of poor sensation. The actual training tasks require the person to practice identifying various sensory stimuli applied randomly across the soles of the foot and they provide responses related to the type of stimulus and the location of the stimulus. The progression of the hierarchy involves more sensitive stimuli, and finer discrimination, based on their previous scores. Stimuli begin with pressure monofilaments and temperature (warm versus cold) and progresses to combination stimuli eg a cold floor tile versus softer warm sand. There is also a task of discriminating foot positions where the person is required to more and more accurately discern the foot position (when repositioned by the therapist). Each session will last a half an hour and the person will be seated or lying comfortably throughout. There will be total of 10 sessions over the 2 week period.
