Comparison Between an Objective Biomechanical Cost and the Physical Perception of a Manual Wheelchair User During Propulsion Tasks
Wheelchair users must be able to move around freely and access public buildings and transport, but current accessibility standards (e.g. maximum 8% ramp slope) are based on limited scientific evidence about the real biomechanical and perceived difficulties encountered by manual wheelchair users in daily life.
Manual wheelchair propulsion is not purely a motor activity: it also involves cognitive and emotional demands (attention, trajectory planning, stress and frustration management) that contribute to a mental workload. This cognitive dimension is still rarely integrated into biomechanical evaluation protocols.
This exploratory (pilot) study aims to test the feasibility of a protocol combining objective biomechanical data (shoulder joint loading estimated from motion capture and instrumented handrims) with the subjective experience of participants (perceived physical demand from the NASA-TLX questionnaire, perceived exertion from the Borg scale), during standardized and more realistic manual wheelchair propulsion tasks, including tasks performed under an added cognitive load (auditory-verbal 2-back dual task).
Inclusion: Adult participant over 18 years of age; Person having signed the informed consent form; Duration of manual wheelchair use prior to the experiment greater than 2 weeks; Ability to perform transfers autonomously, with or without a technical aid; Functional criterion: patient who uses the wheelchair autonomously during the day; Non-inclusion Criteria:; Refusal of the person to participate or to sign the consent form; Diagnosed cognitive disorder; Upper limb amputation; Refusal of the person to propel the wheelchair bimanually; Upper limb injury; Average upper limb pain over the past two weeks, on a 0 (no pain) to 10 scale: < 4; Person aged over 70 years.
