Résumé : | Objective To propose a short version of the lower extremity functional scale (LEFS), to compare our short version with the different structures proposed for the LEFS by the specialized literature, and to verify the criterion validity of the best structure of the LEFS identified in our study. Design Cross-sectional observational study. Setting Physiotherapy clinics. Participants We included 140 patients with lower limb dysfunction (N=140). Interventions None. Main Outcome Measures We used confirmatory factor analysis (CFA), ?2/degree of freedom (DF), comparative fit index (CFI), Tucker-Lewis index (TLI), root mean square error of approximation (RMSEA), standardized root mean squared residual (SRMR), Akaike information criterion (AIC), and Bayesian information criterion (BIC). The method of reducing the number of items of the LEFS considered the modification indices and factor loadings. Results The body site most affected by pain was the knee (71.4%), and the most common diagnoses were knee osteoarthritis (55%) and anterior knee pain (11.4%). LEFS reduction generated a 1-dimensional structure of the LEFS with 10 items (LEFS-10). When compared with other structures, the LEFS-10 presented the best fit indices (?2/DF=1.88, CFI=0.975, TLI=0.968, RMSEA=0.079, and SRMR=0.058) and the lowest values of AIC (3287.063) and BIC (3345.896). LEFS-10 presents a high correlation (Spearman's correlation coefficient [?]=0.911, P<.001 with the lefs. conclusion lefs-10 is proposal for a short version of instrument most adequate internal structure in addition to being satisfactorily correlated longer instrument.> |
