The Effect of Anterior Versus Posterior Walker Use on Posture in the Elderly Person

1 May 1998


The objective of this study was to determine the effects of anterior versus posterior walker use on the posture in the elderly person. The subjects were selected based on predetermined criteria. With consent, a total of 11 subjects participated in this study, 1 male and 10 females. Styrofoam markers were placed on the right ear, acromion, greater trochanter, lateral femoral condyle, and lateral malleolus. This formed three angles: (1) trunk angle (2) hip angle and (3) knee angle. The subjects were video analyzed while ambulating with an anterior walker then a posterior walker. Each subject ambulated 15 meters, three times. The three angles were evaluated at initial contact, midstance and preswing of the gait cycle. Results showed no significant difference between walkers at the three angles during any of the three phases of the gait cycle. Further studies that include current anterior walker users may be beneficial to determine if posture changes with posterior walker use.
