Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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.

Outcomes
Primary outcome [1] 258452 0
Comparing of variables between 0% and 5% 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.
Timepoint [1] 258452 0
After two minutes in 5% of inclination
Primary outcome [2] 258453 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 [2] 258453 0
After two minutes in 10% of inclination
Secondary outcome [1] 264245 0
Comparing of variables between 5% and 10% of inclination as measured by digitised video analysis showed in the hip, flexion at initial contact increased 14,8%, flexion at swing increased 13,6%. There was a decrease of 14% in maximum extension during terminal stance. An increase of 6,0% was also observed in range of motion in the hip.
In the knee, flexion at initial contact increased 19,6%, maximum stance flexion increased 17%. In the ankle, there was increase of 43,6% in the maximum swing dorsiflexion.
Timepoint [1] 264245 0
After two minutes in 10% of inclination
