Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The overall duration of study was 6 months.The subjects were assessed for motor function and classified at level 1 of the Gross Motor Function Classification System (GMFCS), were evaluated. A subjective assessment of balance was performed using a questionnaire (Berg`s Balance Scale-BBS). Spatial-temporal variables of the lower limbs 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 two different inclinations (0% and 10%) during 2 minutes in each condition. The treadmill was then turned on and the participants walked at a comfortable speed. 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% and 10%. A one-minute rest period was given between the different conditions. The overall duration of the treadmill session was of approximately 6 minutes.

Outcomes
Primary outcome [1] 259596 0
Comparing of variables between 0% and 10% of inclination as measured by digitised video analysis showed that the stance time increased 4,8%.
In the hip, flexion at initial contact increased 13%, flexion at swing increased 10,2%, there was a decrease of 13% in maximum extension during terminal stance.

After two minutes in 0% of inclination
Secondary outcome [1] 266229 0
Comparing of variables between 0% and 10% of inclination as measured by digitised video analysis showed that the stance time increased 6%.
In the hip, flexion at initial contact increased 29,7%, flexion at swing increased 25,2%. There was a decrease of 25,2% in maximum extension during terminal stance. An increase of 8,7% was also observed in range of motion in the hip.
In the knee, flexion at initial contact increased 30%, maximum stance flexion increased 21,4%, range of motion increased 5,8%. In the ankle, there was decrease of 67,7% in the plantar flexed.
Timepoint [1] 266229 0
