Brief Summary:

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.


Condition or disease Intervention/treatment Phase
Duchenne Muscular Dystrophy Spinal Muscular Atrophy Other: Alert "AFNOR 3.6". Other: Alertes " AFNOR 3.6 " et alertes " Guidelines ". Not Applicable

Detailed Description:

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.

Arm Intervention/treatment
AFNOR 3.6 alerts
Alert called "AFNOR 3.6" in connection with the dispersion index described by Drummond et al 1985 and validated by Sprigle et al 2003. This alert corresponds to the quantification of the percentage of weight on the slick distributed over a small area (55% on one to three zones totalling 30cm2),
Other: Alert "AFNOR 3.6".
This alert corresponds to the quantification of the percentage of weight on the slick distributed over a small area (55% on one to three zones totalling 30cm2),

AFNOR 3.6 alerts and Guidelines
AFNOR 3.6" alerts and "Guidelines" alerts. By alertes Guidelines we mean the clinical recommendations of the Spinal Cord medicine association, i.e. weight relief every 15 to 30 minutes (Bergstrom et al., 1992; Nixon, 1985; Ho and Bogie, 2007) over a period of 1 minute 51 (Coggrave and Rose 2003) for spinal cord injuries. For patients who do not push up, a tilt of at least 25° of seat and 120° of backrest or a minimum of 45° in one block (Dicianno et al. 2009).
Other: Alertes " AFNOR 3.6 " et alertes " Guidelines ".
By alertes Guidelines we mean the clinical recommendations of the Spinal Cord medicine association, i.e. weight relief every 15 to 30 minutes over a period of 1 minute 51 for spinal cord injuries. For patients who do not push up, a tilt of at least 25° of seat and 120° of backrest or a minimum of 45° in one block.




Primary Outcome Measures :
  1. Evaluate the impact of a device, monitoring the wheelchair user's risk of pressure sores and issuing alerts based on international recommendations, on the support reliefs provided by the subject in an ecological situation [ Time Frame: 14 days ]
    Primary outcome will be evaluated with the number of modification of relief or changing of position with or without alert. The metric used will be the number of average reliefs per hour performed by the patient. This number of reliefs will be compared with and without an alert system.


Secondary Outcome Measures :
  1. the differences in occupational performance at the MCRO (Mesure canadienne du rendement occupationnel) score [ Time Frame: 14 days ]
    Analyze the differences in occupational performance at the MCRO score. An improvement in MCRO score will mean an improvement of occupational performance in psychosocial dimensions.

  2. the impact of visual biofeedback of the pressure print on chair [ Time Frame: 14 days ]
    Quantify the impact of visual biofeedback of the pressure print on chair positioning by modification of the seat within 5 minutes following the visual cartography consultation

  3. Feasibility study of integrating international recommendations to reduce the risk of pressure ulcers in a medical device [ Time Frame: 14 days ]
    the aim is to verify the technical feasibility of integrating international recommendations to reduce the risk of pressure ulcers in a medical device in relation to the position in the chair through: adequacy between pressure cartography the same label posture over time as well as adequacy between the alert and the type of pressure imprint

  4. the study of the acceptability by the patient of alerts in relation with international recommendations [ Time Frame: 14 days ]
    the study of the acceptability by the patient of alerts in relation with international recommendations will be evaluated with the duration of change in alert characteristics by patient after two days of non-modifiable alerts

  5. the study of the acceptability by the patient of alerts in relation with international recommendations [ Time Frame: 14 days ]
    the study of the acceptability by the patient of alerts in relation with international recommendations will be evaluated with the frequency of change in alert characteristics by patient after two days of non-modifiable alerts
