| الوصف: | Purpose: The purpose of this study was to establish reliability and validity of a clinically useful gait classification system for older adults using gait and physical performance measures in 2 different populations. Methods: We classified gait patterns using structured clinical observation and expected the gait patterns to be defined by variability of movement (consistent, inconsistent) and postural biomechanical factors (usual, flexed, extended, crouched) observed in walking. Male veterans (n=106) referred to the VA GEM Program (mean age, 76; SD, 7.1; range, 63-97 years) were videotaped for analyses. The inter- and intra-rater reliability was determined. Pair-wise comparisons across various groups were performed to validate the gait classification using gait parameters (gait speed, step length, width and variability), lower extremity range of motion and muscle strength, physical function in ADL (Physical Performance Test, PPT) and gait abnormalities (GARS-M). The validity of the gait classification system was further validated in a different population consisting of 34 community-dwelling older adults (mean age, 84; SD, 5.0; range, 70-91 years). Results: Kappas for interrater reliability of the variability and postural components of the gait classification system were 0.59 and 0.75, respectively; for intrarater reliability, 0.82 and 0.72, respectively. Consistent and inconsistent groups were different in gait speed (0.66 and 0.49m/s, respectively; p=0.003), step length (0.46 and 0.38m; p=0.008), step length variability (7.47% and 12.74%; p=0.043), the PPT (15.80 and 11.73; p |
