Changes in Attention Level Due to Isometric Exercises and Level Three Progression Eccentric Movements

Study Overview
=================
Brief Summary
-----------------
Determine the changes in attention level due to isometric exercises and level three progression eccentric movements. The attention level will be measured using a mental speed test (how quickly a subject can process information and make decisions based upon that information). Another outcome measure will be the ability of the subject to maintain balance

Detailed Description
-----------------
On Day 1, subjects will complete the mental speed test and will undergo CDP testing using the modified Clinical Testing of Sensory Integration in Balance (mCTSIB) protocol: the subjects will be required to stand on a hard or compliant surface (a 4 tall foam cushion of known mechanical properties) in a comfortable posture, feet shoulder width, with eyes open or closed, head straight and arms to the side and free to move, gazing forward, and breathing normally. These will constitute the baseline information. Subjects will be divided into two groups: a isometric group (performing the isometric exercises) and an eccentric group (performing the eccentric exercises). At the end of Day 1, the isometric group will perform the isometric exercises while the eccentric group will act as control (no exercise). On Day 2, subjects will complete the mental speed test and will undergo the CDP testing a second time. These will constitute the first follow-up information. At the end of Day 2, the eccentric group will perform the eccentric exercises while the isometric group will act as control (no exercise). Throughout Day 3, subjects will complete the mental speed test and undergo the CDP testing a third time. This will constitute the second and last follow-up information.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in Stability Score | The Stability Score is calculated as percentage ratio of the actual sway and the theoretical limit of stability. Changes in Stability Score will be assessed between baseline (Day 1), and Day 2 and Day 3. It will be used to investigate if and which exercises affect it and how much. | Baseline, Day 2 and Day 3 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in Mental Speed | The subject will be presented a series of word/image pairs and/or simple mathematical equations or number sequences. If a pair matches, the subject has to click the Correct button, if the pair does not match, the Incorrect button . However, if the word Opposite appears at the top of the screen, the answer needs to be reversed. The subject has up to 5 minutes to complete the task. The Accuracy of the answers expressed as percentage will be used as measure of mental speed. Changes in Accuracy will be assessed between baseline (Day 1), and Day 2 and Day 3. It will be used to investigate if and which exercises affect it and how much. | Baseline, Day 2 and Day 3 |
