Korean Translation and Psychometric Properties of Self-Report Instrument for Mobility Measuring for Adults With Lower Limb Amputation

Year: 2025
Type: article
Abstract: Objective: To assess mobility in prosthetic limb users, the Prosthetic Limb Users Survey of Mobility (PLUS-M) was developed as a brief item bank. The PLUS-M exhibits good reliability and has been translated into more than 15 languages; however, a Korean translation is not yet available. Therefore, this study translated the 44 items of PLUS-M into the Korean language and analysed the psychometric properties of the PLUS-M/Short Form 12 (PLUS-M/SF- 12) instrument through official procedures. METHODS: The process of Korean translation began with a consultation with the developer of the PLUS-M and included the first and second compatibility verification, back-translation, back-translation verification by the developer, and the final approval of the Korean version. This study tested validity using different instruments such as Activities-specific Balance Confidence scale, 2-Minute Walk Test, Timed Up and Go Test to assess various characteristics related to mobility. The translated version PLUS-M was then sent to two physical therapists working at Incheon Hospital and one prosthetist working at a Rehabilitation Engineering Center for them to assess the appropriateness of term use and understanding of the instrument. RESULTS: The study found excellent internal consistency and test-retest reliability of the PLUS-M/SF-12 Korean version questionnaire, indicating its reliability and predictability across repeated measurements. Conclusion: This study provided a tool to assess the mobility of individuals with lower limb amputations.
