Motor imagery
Brief summary
The main objective is to evaluate and quantify the manual gripping force caused by mental practice
Interventions
BEHAVIORALMotor imagery
The person will have to imagine different scenarios of manual gripping
BEHAVIORALPlacebo intervention
The placebo group will imagine a place without the presence of humans.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Hand grip strength | Change from baseline and immediately post-intervention | It is a variable of gripping force measured in the unit of Newtons |
| Pain pressure threshold | Change from baseline and immediately post-intervention | Pressure Pain Threshold (PPT) is one of these tests and it is defined as the minimum force applied which induces pain. The measurement shall be carried out by using an algometer (pressure device that induces mechanical stimuli) is to standardize the amount of pressure applied in the neck region. The reliability of pressure pain thresholds according to raters or measurement frequencies is relatively high |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Visual and Kinesthetic Motor Imagery Ability | Immediately before the intervention | Visual and Kinesthetic Motor Imagery Ability will be measured with Movement Imagery Questionnaire-Revised (MIQ-R). MIQ-R has four movements repeated in two subscales, a visual and a kinesthetic one. Additionally, a score between 1 and 7 is assigned, with 1 representing difficulty in picturing the motor image or difficulty in feeling the movement previously made, and 7 representing the maximum ease. The internal consistencies of the MIQ-R have been consistently adequate with Cronbach's α coefficients ranging above 0.84 for the total scale, 0.80 for de visual subscale and 0.84 for the kinesthetic subscale. |
| The degree of physical activity | Immediately before the intervention. | The degree of physical activity was objectified through the The International Physical Activity Questionnaire (IPAQ) questionnaire, which allows the subjects to be divided into three groups according to their level of activity, which can be high, moderate, and low or inactive. The IPAQ consists of 7 questions about the frequency, duration and intensity of activity (moderate and intense) performed in the last seven days, as well as walking and sitting time on a workday. The IPAQ scoring protocol assigns the following MET values to walking, moderate, and vigorous intensity activity: 3.3 METs, 4.0 METs, and 8.0 METs, respectively. |
