Empowering elderly women with osteoarthritis through hands-on exploration of adaptive equipment concepts.

The study investigated the participation experiences of elderly women with hand limitations in a maketools-inspired activity for improving bottle openability and verified the usefulness of the results from this approach. Participatory design was used to stimulate participants' hands-on fabrication of new bottle lid concepts. Air-dry modeling clay, Crayola Model Magic® (Crayola LLC, 1100 Church Lane Easton, PA 18044-0431), clay modeling tools sets and empty bottles were the tools used to explore feasible and user-envisioned ideal lids that could potentially reduce hand pain and improve function when opening bottles. Twenty-five elderly women fully participated in the study. They generated 36 bottle lid design concepts. Qualitative analysis identified inclusion of four primary design features as follows: 1) surface texture; 2) increased leverage through lid shape or diameters; 3) increased contact surface with palm/fingers through lid shape or height; and 4) facilitation of alternative grip types. The major limitations of the study were inclusion of only women participants and healthier persons living in a retirement community. Future research is needed to investigate the bottle lid preferences of men and persons with more severe hand function living in places other than independent living communities.
