Brief summary
The aim of this study was to analyze the effects of electric treadmill inclination on the gait of individuals with chronic hemiparesis. Eighteen individuals, mean age of 55.3±9.3 years and lesion time of 36±22.8 months. The subjects were assessed for functional independence (Measure of Functional Independence) and balance (Berg Balance Scale). Spatial-temporal variables were observed as well as the angular variation of the hip, knee and ankle in the sagittal plane while the individuals walked on the treadmill at three different inclinations (0%, 5% and 10%). There was an increase in stance time between 0% and 5% and 0% and 10%. The other spatial-temporal variables did not change. During initial contact there was an increase in the hip, knee and ankle flexion angle. An increase in hip amplitude was also observed between 0% and 10% and 5% and 10% and in knee amplitude between 0% and 10%, as well as decreased hip extension and increased dorsiflexion. Treadmill inclination promoted angular alterations such as an increase in hip, knee and ankle angle during initial contact and the swing phase and an increase in the AOM (amplitude of movement) of the hip and knee, as well as an increase in stance time of the paretic lower limb.

The subjects were assessed for functional independence (Measure of Functional Independence) and balance (Berg Balance Scale). Spatial-temporal variables of the hemiparetic lower limb were observed as well as the angular variation of the hip, knee and ankle in the sagittal plane while the individuals walked on the treadmill at three different inclinations (0%, 5% and 10%) during 2 minutes in each condition. The treadmill was then turned on and the speed gradually increased until it reached the velocity calculated during the 10-meter test. After two minutes, a 30-second capture was made (dynamic collection). All the individuals were submitted to collections on the treadmill with inclinations of 0%, 5% and 10%. A three-minute rest period was given between the different conditions. The overall duration of the treadmill session was of approximately 14 minutes.
