Effect of Referent Type on Balance in Action Observation.
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.

About this study
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.
Who can participate
Healthy volunteers accepted: Yes
Only the study team can determine whether someone qualifies for participation.
Inclusion criteria
- Be of legal age.
- Have a mobile device.
- Have normal or corrected-to-normal vision.
- Absence of neurological, orthopedic or vestibular disorders.
- Absence of specific balance skills due to competitive sports.
- Obtain a score of 3 or less on the Tegner activity scale.
- Having voluntarily signed the informed consent and being willing to follow the protocol proposed by the research team.
Exclusion criteria
- History of participation in any study with movement representation methods.
- Subjects with impaired communication and/or compression.
Treatment and study plan
Action observation videos
OtherThe participant will see videos of balance exercises performed by the assigned reference, depending on their group, without performing any physical movement.
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
-
Age
Time frame: 1 day
Age will be measured in years
-
Biological sex
Time frame: 1 day
Biological sex will be measured asking if they born like a boy or a girl.
-
Weight
Time frame: 1 day
Weight will be measured in kg with a Beurer's body analyser scales
-
Height
Time frame: 1 day
Height will be measured in cm.
-
Body mass index (BMI)
Time frame: 1 day
Body mass index (BMI) will be measured in kg with a Beurer's body analyser scales
-
Length of the lower limb.
Time frame: 1 day
Length of the lower limb will be measured in cm.
-
Dominant lower limb
Time frame: 1 day
Dominant lower limb will be measured asking which limb would shoot a ball with.
-
Morphotype
Time frame: 1 day
Morphotype (endomorph, ectomorph and mesoform) will be measured by observation
-
Trunk and lower extremity muscle strength
Time frame: 1 month
Analogue dynamometry will be used as an evaluation method and will be recorded in Newtons (N) with the Saehan SKU SH5007 back, leg and chest dynamometer.
-
Satisfaction assessed by a selfcreate questionnaire
Time frame: 1 day
A questionnaire specifically designed to evaluate participants' satisfaction with their experience in the study will be used once they have completed their participation.
