Measurement is a fundamental element of good practice for physiotherapists. The purpose of this “Outcome Measures” trial is to critically evaluate the use of therapeutic measures for the physical rehabilitation of a patient. Say no to plagiarism.

For the physiotherapy intervention (assessment and rehabilitation) of this patient's body structure and function (impairments), the Lower Limb Functional Scale (LEFS), Foot and Ankle Disability Index ( FADI) and the gateway system will be taken into account. The professional autonomy of the physiotherapist lies in the exercise of his professional judgment within the limits of his knowledge and skills, both in terms of health promotion and care provision. They must take responsibility for their professional practice and decisions, including making independent judgments, where 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 support judgments and recommended solutions, which is closely linked to measurement and evaluation. In patient care, evidence-based practice is the conscious use of the best available evidence in clinical decision-making. For the purposes of this trial, a systematic search was carried out in selected databases (PubMed, Physiopedia, Google Scholar & PM&RKnowledge) to evaluate the evidence regarding the measurement properties of the LEFS, FADI and walkway, as well as the scores associates. In particular, this literature review aimed to assess the validity, reliability and sensitivity to change of the chosen outcome measures, for different lower limb 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 assess the general condition of our patient since deficiencies 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 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 the LEFS, it has been modified and validated in several language studies around the world, such as Greek, Persian, Indian, Malay and Chinese. In all these studies, the LEFS adapted to all cultures still presents a good profile in terms of reliability and validity. Reliability scores for the LEFS have been rated excellent among several studies and considered a valid tool compared to other patient-rated questionnaires, with greater sensitivity to change than these. The MCID allows clinicians to evaluate pre- and post-treatment outcome scores to determine whether the amount of change occurred.
