Prosthesis donning and doffing questionnaire: Development and validation

Objectives:To develop a questionnaire that specifically evaluates the ability of trans-tibial amputees to don and doff a prosthesis and to investigate the psychometric properties of the newly developed questionnaire.Background:Prosthesis should be donned and doffed few times during the day and night; thus, it is important to measure ease of donning and doffing.Study design:A cross-sectional study.Methods:The questionnaire was designed and evaluated by a group of experts. The final questionnaire was administered to 50 individuals with trans-tibial amputation. A test–retest study was also conducted on 20 amputees to assess the repeatability of questionnaire items.Results:The prosthesis donning and doffing questionnaire was developed and tested through a pilot study. Based on Kappa index, the questionnaire items showed correlation coefficients greater than 0.7, which indicate good reliability and repeatability. The majority of the participants had good hand dexterity (80%) and could perform all types of gras...
