A Modified Version of the Forgotten Joint Score–12 in Lower Limb Amputees: Validity and Reliability Study

OpenAlex English

Adaptation to prosthesis is important for occupation, quality of life, and participation in social life, so it needs to be evaluated. The aim of this study was to determine the validity and reliability of the Forgotten Joint Score–12 (FJS-12) in lower limb amputees. The FJS-12 was applied to 80 amputees. Criterion-referenced validity was assessed using the activity restriction subparameter of Trinity Amputation and Prosthesis Experience Scale (TAPES). The internal consistency of the FJS-12 was high (Cronbach’s α = .943). A statistically significant very good negative correlation was determined between the FJS-12 and the activity restriction subparameter of TAPES ( r = −.641; p < .001). The results of this study showed that FJS-12 is a valid and reliable measurement tool that can be used to assess the adaptation to prosthesis in amputees. Evaluation of prosthesis awareness in daily living activities of amputees is important in terms of establishing occupational therapy and rehabilitation programs.
