Brief Summary:
The aim of this study is to assess the intra and inter-subjects variability of the pressure measurement cartography in healthy and well and able volunteers, sitting on a rigid base during two hours.

Condition or disease Intervention/treatment Phase
Pressure Ulcer Device: Orthotest CE Not Applicable

Detailed Description:
  • The purpose of this study is to understand the formation of pressure sore, to improve the care of paraplegic patients.
  • This pilot study is going to help to establish a model in healthy volunteers in the prevention of pressure sores.

Arm Intervention/treatment
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.

Primary Outcome Measures :
  1. 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 :
  1. Correlation between interface pressure measurements and postural data. [ Time Frame: 2 hours ]
    • Sit pressure measurements
    • Video recording

Other Outcome Measures:
  1. 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.
