EXPERIMENTAL: Mental practice	Behavioral: Motor imagery; The person will have to imagine different scenarios of manual gripping

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pain pressure threshold	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	Change from baseline and immediately post-intervention
Hand grip strength	It is a variable of gripping force measured in the unit of Newtons	Change from baseline and immediately post-intervention

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Visual and Kinesthetic Motor Imagery Ability	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.	Immediately before the intervention
The degree of physical activity	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.	Immediately before the intervention.
