Quality of Life Evaluation Through a Single-Item 'Daily Prosthesis Usage Time' in Individuals with Lower-Limb Amputation

Introduction The purpose of this study was to identify the relation of daily prosthesis usage time (DPUT) of individuals with amputation with quality of life (QoL) questionnaires. Methods The research was carried out on 125 individuals with amputation. Prosthetic-related parameters were searched, as well as demographic data. A generic (Nottingham Health Profile [NHP]) questionnaire and a questionnaire specific to individuals with amputation (Trinity Amputation and Prosthesis Experience Scales [TAPES]) QoL measurements were used. Results Ninety-one males and 28 females with a mean age of 42.4 ± 14.7 years participated in the study. The average DPUT was 11.1 ± 4.4 hrs/d. Study results showed that there was significant correlation between both of the QoL questionnaires (NHP and TAPES) and DPUT. High correlation was determined between DPUT and NHP total score and NHP-Pain, and very high correlation was found between DPUT and NHP-Physical Activity subscale. A moderate negative correlation was found between DPUT and NHP-Energy Level, NHP-Emotional Reaction, NHP-Social Isolation, and NHP-Sleep. A moderate negative correlation was found between DPUT and TAPES-Activity Restriction. A high correlation was found between DPUT and residual limb pain, prosthetic satisfaction, time interval after amputation, and number of prosthetic fittings. A moderate correlation was found between DPUT and walking aids, whereas a poor relationship was shown between phantom pain and DPUT. Conclusions This study showed that "the average DPUT"may be used in terms of short assessment of QoL of individuals with amputation. The outcomes of this study pointed out that especially prosthetic-related parameters affected the QoL in individuals with amputation. In problems resulting from routine assessment and questionnaires having so many items, a single-item question, "the average DPUT,"may be used effectively in a shorter period and is helpful for organizing a rehabilitation program. Clinical Relevance A single-item question, "The average daily prosthesis usage time (DPUT),"be used effectively in a shorter assessment of quality of life of individuals with amputation and is helpful for organizing a rehabilitation program. © Lippincott Williams & Wilkins.
