Problemas con el uso de sillas de ruedas y otras ayudas técnicas y barreras sociales a las que se enfrentan las personas que las utilizan. Estudio cualitativo desde la perspectiva de la ergonomía en personas discapacitadas por enfermedades reumáticas y otras condiciones / Usage problems and social barriers faced by persons with a wheelchair and other aids. Qualitative study from the ergonomics perspective in persons disabled by rheumatoid arthritis and other conditions

Objetivos. Identificar los problemas de uso y accesibilidad a los que se enfrentan las personas discapacitadas (presenten dolor o no) usuarias de ayudas técnicas (sillas de ruedas convencionales); reconocer las barreras físicas que limitan su autonomía, y registrar cuáles son las prácticas socioculturales que los excluyen del proceso de diseño de dichas ayudas. Materiales y método. Participaron 15 pacientes con alguno de los siguientes diagnósticos: espondilitis anquilosante, artritis reumatoide, o amputados que utilizarán sillas de ruedas en México y Colombia. Estudio cualitativo. Análisis: temático y con aproximación teórica del diseño industrial utilizando pruebas de uso para análisis ergonómicos. Resultados. Se identificaron 6 temas asociados a los problemas de uso desde la perspectiva del paciente: barreras que limitan el empleo de las sillas de ruedas (uso y aceptabilidad), adaptaciones creativas, independencia, potencial de uso de las ayudas técnicas (silla de ruedas y/o andaderas), percepción del cuerpo y ayudas técnicas, y barreras arquitectónicas. Las necesidades ergonómicas y de uso, así como el nivel de independencia resultante, son diferentes entre los usuarios de sillas de ruedas que sufren dolor crónico y aquellos cuya discapacidad no involucra dolor. Estos últimos tienen más independencia en sus movimientos y decisiones. Conclusiones. La propuesta del «diseño desde y para el usuario» debe involucrar tanto las perspectivas del técnico en ergonomía y del médico como la interpretación que el usuario hace de su entorno y de la vivencia de la enfermedad (AU)

Objective: The objective of this study was to identify the usage and accessibility problems faced by the disabled (whether in pain or not) users of assistive devices (conventional wheelchairs), identify physical barriers that limit their mobility, and recognize the socio-cultural practices excluding them from the design process of such devices. Another main purpose of this paper is to improve the ergonomic criteria that influence the design and manufacture of assistive devices. Materials and method: Study population: 15 patients with any of the following diagnoses: ankylosing spondylitis, rheumatoid arthritis, or amputees using wheelchairs in Mexico and Colombia. Design: Qualitative study. Thematic analysis with a theoretical industrial design approach to employing usability testing for ergonomic analysis. Results: We identified 6 issues associated with usability problems from the patient’s standpoint: barriers for use of wheelchairs (usability and acceptability), creative adaptations, potential use of technical devices, independence, body perception and assistive devices, and architectural barriers. The ergonomic and usability requirements and the resulting level of independence vary across wheelchair users with chronic pain and those whose disability does not involve pain. The latter are more independent in their movements and decisions. Conclusions: User input is essential in the design of assistive devices. The proposal of “design from and for the user” must rely on both engineering and medical perspective on the ergonomy as well as the user interpretation of the environment and the experience of the disease. Thus we can arrive at a “user-centered design” (AU)
