Reliability and Validity Evaluation of the BePoW Device

Each subject will be invited to a single experimental session lasting approximately one hour, during which all assessments will be performed.

During the visit, the patient will complete an autonomy questionnaire and assess wheelchair fatigue. A spirometry test will be performed.

The measurements will then be recorded by the BePoW software and the occupational therapist.
