Abstract:
Background: Comfort of an orthosis is an important characteristic that is likely to dictate use of and satisfaction with a device. However, instruments to assess only orthosis user comfort do not exist. The Prosthetic Socket Fit Comfort Score, developed previously for prosthesis users, may be adapted to serve this purpose. Objectives: This study's purpose was to assess the validity and reliability of the Orthosis Comfort Score, a self-report instrument adapted from the Prosthetic Socket Fit Comfort Score. Study design: This is a prospective, observational study designed to establish initial evidence of validity and reliability for an outcome measure that assesses comfort. Methods: Ankle foot orthosis users completed the Orthosis Comfort Score and two validated patient satisfaction questionnaires. An orthotist documented an assessment of fit. Post-visit Orthosis Comfort Scores were documented after the appointment and 2-4 weeks later. Orthosis Comfort Scores were compared to the patient satisfaction questionnaires, assessment of fit and orthosis use (hours per week). Results: There were 46 study participants. Orthosis Comfort Scores had a moderate positive correlation with their orthotist's assessment of fit, very strong positive correlations with patient satisfaction questionnaires and fair positive correlation with orthosis use (all correlations p < 0.05). Conclusion: This study demonstrates initial evidence for the validity and reliability of the Orthosis Comfort Score in ankle foot orthosis users.
