Development of a customized booklet of foot-ankle exercises for people with diabetes mellitus as a management and prevention tool for musculoskeletal complications: A customized booklet of foot-ankle exercises for people with diabetes

Background: Diabetes mellitus (DM) and diabetic peripheral neuropathy (DPN) compromises the structures of the musculoskeletal system, especially in the foot-ankle complex. Foot-related exercises can be a promising tool to be incorporated in health care programs to manage and prevent musculoskeletal complications resulting from DM and DPN progression.

Objective: To present the development, validation, and usability evaluation of a booklet that directs training and personalizes the progression of a home-based program of foot-ankle exercises.

Methods: The booklet containing a foot-ankle exercise program developed in a previous clinical trial was validated using the Delphi technique, with a multi-professional jury of experts who assessed the content of the material, language, individual education, exercise execution, exercise quality, and material implementation. The validated version was evaluated through telephone interview by a convenience sample of 10 individuals with DPN regarding its relevance, health education, comprehension, and usability.

Results: The validation process with experts was performed in two rounds achieving 100% agreement in the second round. During the usability evaluation process the main complaint of users was that performing all the exercises was very tiring and took too much time out of their daily routine. Thus, the number of repetitions for each exercise was changed from 30 to 12.

Conclusion: The booklet is a material for prevention and management of the impacts of DM and DPN progression by improving the musculoskeletal function of the foot-ankle. This material provides an exercise regime with a personalized progression based on the perceived effort of the users.
