Summary
We hypothesize that response to an unexpected
As far as we know, there is a lack of studies investigating the learning effect of random vs.
block non-random training on balance recovery responses while walking and exposure to
unexpected
Description
- Goals
-
- Determine the relationship between gait stability (as measured in the Lab) and brain function (MRI) in 50 old (70 years old and over) and 10 young adults (20-40 years old) that represent heathy brain.
- To determine which of the training intervention methods (25 older adults that participate in random training vs. 25 older adults that participate in block non-random training) are more beneficial for balance recovery responses and for improved brain function.
Methods: This study is a clinical investigation study. First stage - Individuals that show an interest in participating in the study will be exposed to a brief interview before further testing is performed to see if they fit the inclusion-exclusion criteria. Individuals who pass the interview a screening, and physical examination and the additional questionnaires and functional tests described below.
Second stage - Testing different motor learning paradigms for improving balance recovery
ability: A convenience sample of 60 healthy subjects (10 young's, 50 older adults) will be
recruited. After testing their clinical balance performance (Berg
Outcome measures: The stepping threshold as measured by the distance of the platform movements in centimeters will be measured. Quantitative parameters of the compensatory stepping/ and motor ability (i.e., step reaction time, step time, step length), descriptive parameters of the stepping strategy after perturbation
(i.e., arm responses, upper body responses, leg step threshold and
The aims of this study are to determine the relationship between the different requirements for gait stability (walking without perturbations, ability to overcome small perturbations, ability to overcome larger perturbations and, largest recoverable perturbation during walking) and brain function and anatomy. The research hypothesis: there is a correlation between the age related atrophies in areas of the brain and functional capacity
Third stage - A Randomized control trial we will compare two perturbation motor learning paradigms with different challenge level of the practice condition (i.e. blocked practice vs random practice). According to motor learning theory we hypothesize that a) healthy older adults will benefit more from random practice. The purpose of this stage is to investigate the effects of task practice order (random vs blocked) on motor learning (i.e. responding to perturbations during walking) in older adults. According to motor learning theory we hypothesize that a) healthy older adults will benefit more from the random motor learning approach as compared to using blocked practice.
