Training on Unstable Surfaces and Effects on the Balance of Healthy Young People

Study Overview
=================
Brief Summary
-----------------
The objective of this study is to determine the effects on balance and postural control produced by the implementation of a training program that includes work with unstable surfaces in its methods. It also seeks to quantify to what extent the benefits exceed those achieved with a training of similar characteristics, but implemented on a stable surface. An intensive program is proposed, whose target population is young adults.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Y-balance test | Dynamic balance. The maximum length in cm achieved for each leg in the anterior, posterior-lateral and medial-lateral positions will be recorded. | change from baseline to end of intervention (4weeks) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Posturography (1) | A force T-plate platform will be used to assess posture in terms of sway area (mm2) | change from baseline to end of intervention (4weeks) | 
| Posturography (2) | A force T-plate platform will be used to assess posture in terms of mean velocity (m/s) | change from baseline to end of intervention (4weeks) | 
| Emery test | Static balance and proprioception as measured with the eyes closed to keep balance with one leg over an Airex(R) balance pad. The time in seconds will be recorded. | change from baseline to end of intervention (4weeks) | 
| Functional reach | Test of stability, measured as the distance reached when leaning forward without falling (cm) | change from baseline to end of intervention (4weeks) |
