Effects of Lower Limb Positive Pressure on the Balance of Community-dwelling Older Adults

August 5, 2021 updated by: Riphah International University
With the onset of the sixth decade in life, degenerative processes affect the neuromuscular system in terms of losses in muscle strength (dynapenia) and muscle mass (sarcopenia). Neural (e.g., numerical loss of alpha motoneurons) and morphological factors. Borde et al. 123 number and size of particularly type-II muscle fibers), as well as their interaction, are responsible for age-related declines in muscle strength and mass. There is evidence that muscular weakness is highly associated with impaired mobility and an increased risk for falls. Moreover, lower extremity muscle weakness was identified as the dominant intrinsic fall-risk factor with a five-fold increase in the risk of falling. An anti-gravity treadmill allows users to walk or run in a reduced body weight environment. The user walks or runs on a treadmill belt surrounded by an enclosed, air-filled chamber. When air pressure increases, an upward force offloads the weight of the runner and decreases the percentage of body weight (BW%) experienced upon foot impact. So, a research question was developed in our mind after the literature review. Is there any effect of AGT training on fall risk of older adults?

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

ACTIVE_COMPARATOR: Normal Treadmill
After completion of the baseline evaluation, Group A participants will exercise for 25 minutes under low-load walking conditions three times a week for 8 consecutive weeks on the AGT treadmill at a set speed of 3.1 mph at a 0-degree incline. For each session, 20% support will be given to participants

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Timed up and go test (TUG)
Time Frame: 12 week
Test is also commonly used to evaluate fall risk.A faster time for completion of required task indicates a better ability to perform functional activities. The person sits up from the chair after instruction and walks at his normal pace for 3 meters, takes a turn and sits down after walking back towards the chair. The total duration required for this activity is measured using a stop watch.
12 week
Berg balance scale
Time Frame: 12 week
Evaluation of functional balance was done using BBS which is valid and reliable tool for dynamic and static balance assessment. It consists of 14 Items and balance is assessed using an ordinal scale comprising 5 points that ranges from 0 to 4. High scores are indicative of superior balance where as low scores are suggestive of increased fall risk and poor balance.
12 week
Functional reach test
Time Frame: 12 week
This test is used to assess stability level of patient. The assessment is carried out by calculating the maximum distance a person is able to reach forward in a fixed standing position. The assessment is carried out by calculating the maximum distance a person is able to reach forward in a fixed standing position. Lower distance of functional reach test indicated higher risk of fall and deteriorated balance and vice versa.
12 week
Fall risk score
Time Frame: 12 week
FRS provide an objective assessment of static and dynamic balance and was assessed using dynamic posturo graphy system. High scores of FRS indicated higher risk of fall and deteriorated balance and vice versa.
12 week
Balance App
Time Frame: 12 week
There are six different tasks that subject have perform with system, like, normal walking up to 6 meters, walking with head movement, standing with eyes open and close and standing on a compromised surface with eyes open and close. High scores indicated higher risk of fall and deteriorated balance and vice versa.
12 week

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Force Plate
Time Frame: 12 week.
Force plates is portable, non-invasive and quantitative instrument used to measure the ground reaction forces, variation in center of gravity and forces impact on foot. Postural sways will be calculated from force plate data. Randomness in data show increase risk of fall and poor balance.
12 week.
