Characterization of the Postural Habits of Wheelchair Users Analysis of the Acceptability of International Recommendations in the Prevention of Pressure Sores Risk by Using a Connected Textile Sensor

Characterization of the Postural Habits of Wheelchair Users in an Ecological Situation and Analysis of the Acceptability of International Recommendations in the Prevention of Pressure Sores Risk by Using a Connected Textile Sensor Integrating an Artificial Intelligence Algorithm

Spinal cord injuries and people with Duchenne Muscular Dystrophy or Infant Spinal Muscular Atrophy (ISA) are prone to pain and pressure sores associated with prolonged sitting. For this reason, it is recommended that people with spinal cord injuries release pressure every 15 to 30 minutes and motorized wheelchair users use the electric positioning functions at least 1 minute every hour.

The aim is to prevent and/or reduce pain and pressure sores. These devices could help to observe daily the variability of users' pressure maps, their impact on occupational performance, the link with pain and redness and could propose customized adjustments.

The main objective of this study is to evaluate the impact of an algorithm that characterizes the cruro-ischiatic fingerprints used in daily life and that issues an alert in case of detection of a pressure sore risk defined by the literature on the occupational performance of the subjects.

The resulting assumption is based on the following points:

• The algorithms implemented in this device are able to calculate and isolate a number of cruro-ischiatic fingerprints used during the day during priority activities and active or passive position changes.
• They may, in the event of a risk position, issue alerts based on the recommendations.

This will allow us to analyze the impact of these alerts on the changes in position and relief actually performed by the subject, analyze the consequences on the MCRO score (psychosocial impact on occupational performance) and verify the impact of visual biofeedback on chair positioning.

Inclusion Criteria:

• Men or women over 18 years of age,

• Daily user of a FR (more than 3 hours per day):

  • 25° of the seat and 120° of the backrest,
  • 45° of sitting in one block,

Exclusion Criteria:

• Refusal of the patient to participate in the study,
• School level lower than cycle 3 not allowing to understand the use of the embedded device,
