Further study details as provided by University Hospital, Grenoble:

Primary Outcome Measures:
  • Assessment of intra and inter-subjects variability of the pressure measurements for the whole population included. [ Time Frame: 2 hours ]
    Sit pressure measurements of all subjects of the study

Secondary Outcome Measures:
  • Correlation between interface pressure measurements and postural data. [ Time Frame: 2 hours ]
    • Sit pressure measurements
    • Video recording

Other Outcome Measures:
  • Correlation between interface pressure measurements and the response to micro electrical stimulation of the buttock. [ Time Frame: 2 hours ]
    • Sit pressure measurements
    • Body composition: body fat mass, lean body mass, water body, bone mineral content etc.

Enrollment: 30
Study Start Date: May 2013
Study Completion Date: August 2013
Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Pressure Measurement Device: Orthotest CE

Orthotest CE is a rigid base mapping system composed by 1024 pressure transducers uniformly distributed in a 35x35 cm surface.

Orthotest CE is a product manufactured by Vista-Medical. The patient sit on the rigid base during 2 hours to record the pressure and all the data needed for the pilot study.
