Study Overview
Brief Summary
The objective of the study is to analyze whether observing the actions of a referent selected by the participants improves balance in asymptomatic individuals compared to those who observe a standard referent.
Detailed Description
Design: Randomized controlled clinical trial. The primary endpoint of the study was the balance recorded by force platform (estatic) and Y balance test (dynamic).
Setting: The participants will be healthy people in the province of Tarragona.
Participants: They will be randomly assigned to one of three groups using a computerized randomized list:
- Control Group (CG): Participants will watch a video of landscapes without human or animal movement.
- Intervention Group with Referent (GIR): Participants will observe actions whose referent has been selected by themselves based on perceived similarity.
- Standard Intervention Group (GIE): Participants will observe actions with a standard reference.

Arms & Interventions
Control Group
Participants will watch a video of landscapes without human or animal movement.
Intervention Group with Referent (GIR)
Participants will observe actions whose referent has been selected by themselves based on perceived similarity. A total of 16 different videos will be used, with 4 new videos each week. The videos will gradually increase in difficulty as the study progresses. All exercises are exercises used to improve balance.
Intervention: Action observation videos (Other)
Standard Intervention Group (GIE)
Participants will observe actions with a standard reference. In this case, a basic digitally designed faceless doll will be used. A total of 16 different videos will be used, with 4 new videos each week. The videos will gradually increase in difficulty as the study progresses. All exercises are exercises used to improve balance.
Intervention: Action observation videos (Other)
Outcomes
Primary Outcomes
Static balance
Time Frame: 1 month
Center of pressure analysis: The displacement of the center of pressure (CPD) of the participants will be measured through posturographic tests performed on a force platform. The following variables related to the center of pressure (CoP) will be calculated: the roll area (in square millimeters) and the distribution of the weight load on both sides.
Dynamic Balance
Time Frame: 1 month
A modified and abbreviated version of the Star Excursion Balance Test, known as mSEBT, will be used. This test has been standardized and validated, and requires a board or floor with three lines indicating directions of movement: anterior (ANT), posteromedial (PM), and posterolateral (PL). These lines form a Y, with an angle of 90° between PM and PL, and 135° between ANT and PM, and ANT and PL.
Secondary Outcomes
- Body mass index (BMI)(1 day)
- Biological sex(1 day)
- Length of the lower limb.(1 day)
- Dominant lower limb(1 day)
- Trunk and lower extremity muscle strength(1 month)
- Weight(1 day)
- Height(1 day)
- Morphotype(1 day)
- Age(1 day)
- Satisfaction assessed by a selfcreate questionnaire(1 day)
