Descrição detalhada
Individuals were mechanically supported on a BWS system as they walked on ground level. All individuals started the training with 30% of body weight unloading and after three weeks, this percentage was reduced to 20% for the remainder of the six-week training period. The criterion used to reduce the percentage of BWS was the individual's ability to maintain alignment of the trunk and to transfer the weight to and from the paretic limb during gait. Individuals' body mass was measured weekly to ensure the appropriate percentage of body weight unloading.
During the training sessions, a physical therapist encouraged the individuals to walk as fast as possible, and feedback was provided in order to improve gait performance, such as vertical alignment of the trunk, symmetric limb weight distribution, and proper movement of the lower limbs. Heart rate and blood pressure were observed at beginning and end of each session, and when the patients reported any symptoms of discomfort during the session. Rest periods were allowed during the training sessions according to individual need.
All individuals were submitted to gait training sessions of 45 minutes, three times a week, on alternating day during six weeks, completing a total of 18 sessions. None of them were given any other type of physical intervention or conventional gait training, stretching, muscle strengthening or endurance exercise while participating in this study.
In order to verify the effects of the described gait training, individuals were assessed before and after gait training program, walking freely at self-selected comfortable speed along a 10 m walkway six times. They were videotaped by four digital cameras (AG-DVC7P, Panasonic) at 60 Hz, which were positioned bilaterally in order to allow simultaneous kinematics measurement of paretic and nonparetic limbs in either direction of motion (from left to right and vice-versa). During the evaluation, individuals were not allowed to use any assistive device, and they walked with the physical therapists' assistance to keep balance, when necessary.
Passive reflective markers were placed on the nonparetic and paretic sides of the body at the following anatomical locations: head of the fifth metatarsal, lateral malleolus, lateral epicondyle of the femur, greater trochanter, and acromion, in order to define the foot, shank, thigh, and trunk segments, respectively. The digitalization and the reconstruction of all markers were performed using Ariel Performance Analysis System - APAS (Ariel Dynamics, Inc.) software, and filtering and posterior analyses were performed using Matlab software (MathWorks, Inc. - Version 6.5). Reconstruction of the real coordinates was performed using the direct linear transformation (DLT) procedure.
