Measurement is a fundamental component of good physiotherapist practice. The purpose of this “Outcome Measures” essay is to critically evaluate the use of therapeutic measures for the physical rehabilitation of a patient. We say no to plagiarism.

For the physiotherapeutic intervention (assessment and rehabilitation) of the body structure and function (impairments) of this patient, the lower limb functional scale (LEFS), the foot and ankle disability index (FADI) and the walkway system. The professional autonomy of the physiotherapist lies in exercising professional judgment within the limits of knowledge and skills, both in health promotion and in the provision of care. They should take responsibility for their professional practice and decisions, in particular by making independent judgments, for which they have knowledge and skills and for which they can be held accountable. However, it must be recognized that only the ability to collect, select and interpret relevant information allows them to corroborate the judgments and solutions supported, which is closely linked to measurement and evaluation. With respect to patient care, evidence-based practice corresponds to the conscious use of the best available evidence in clinical decision-making. For the purpose of this essay, a systematic search of selected databases (PubMed, Physiopedia, Google Scholar & PM&RKnowledge) was performed to evaluate the evidence regarding the measurement properties of LEFS, FADI and walkway and their scores. In particular, this literature review aimed to evaluate the validity, reliability and sensitivity to change of the chosen outcome measures, across different lower extremity impairments, and to discuss the application of the evidence to the presented clinical case. The Lower Extremity Functional Scale (LEFS) can be used to assess the impairment of patients with lower extremity functional conditions or to measure patient progress for a wide range of lower extremity disorders. This tool was chosen to evaluate the general condition of our patient since disorders were observed in the hip, knee, foot and ankle. Easy to administer, no training required. This is a 20-item self-report questionnaire that assesses the current ability to undertake normal daily activities, the LEFS score range is 0 to 80, with higher scores representing better function. Since the creation of the original English version of LEFS, it has been modified and validated in multiple linguistic studies around the world, such as Greek, Persian, Indian, Malay, Chinese. Across these studies, the cross-culturally adapted LEFS continues to have a good profile in terms of reliability and validity. The reliability scores of the LEFS have been found to be excellent in several studies and considered a valid tool compared to other patient-rated questionnaires, with a sensitivity to change higher than those. The MCID allows clinicians to evaluate pre- and post-treatment outcome scores to determine whether the amount of change that occurred would be perceived as significant. The MCID is defined as the smallest change on a scale that would be.
