Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) V2. Spanish version. The SF-36 is a 36- item scale constructed to survey health status and quality of life. It yields an 8-scale profile of functional health and well-being scores as well as psychometrically-based physical and mental health summary. Each scale is directly transformed into a 0-100 scale. Higher scores indicate better overall quality of life.

Zarit Carer Burden Interview. Spanish Version. It´s a questionnaire that evaluates carer burden and asks about many commonly reported difficulties faced by carers (intraclass correlation coefficient = .71). This questionnaire presents 22 Likert-type questions each of which has a score of 0 to 4. The total score can be from 0 to 88. Higher values indicate greater burden caregiver.

Goldberg Anxiety Scale. Spanish version. It´s a self-reported measure that contains 9 questions designed to assed people anxiety. Scores range from 0-9. A higher score indicates a higher level anxiety

The 15-item abbreviated version of the Geriatric Depression Scale (GDS), which measures depression (internal consistency, Cronbach's α = .80). A score of 4 or more has been reported to indicate clinical signs of depression.

Visual analog scale (VAS). The Vas is a 100 mm long horizontal line ranging from "0: no pain at all" on one end to "100: worst pain imaginable" on the other end. Participants mara a point along the line that best represents the pain they are experiencing at that moment. A higher score indicates a higher level of pain

Roland-Morris Disability Questionnaire (RMDQ).Spanish version. It is a self-administered disability questionnaire consisting of 24 questions that are specifically related to physical functions that may be affected by back pain. Score range from 0-24. A higher score indicates a higher level of Disability

Modification of the body mass index (BMI). Wheight in Kg and Height ill be combined to report BMI in kg/m^2

Handgrip strength will be assess for both hands by using a hand dynamometer (TKK 5401, Japan) and the mean value of both hands (kg*m2) is considered to be outcome.

Lower extremity function is assessed by using the "30 Second chair stand test". The patient is asked to stand upright from a standardized chair (0.43 m in height) with arms folded across the chest and to sit back down as many time as he can in 30 seconds.

Postural balance is assessed by performing a blind flamingo test in which the barefoot subject stood with eyes closed on one leg, while the other leg is flexed at knee leven al held at the anckle by the hand of the same side of the body. The number of trials that the subject needed to complete 30 seconds of the static position is measured. The outcomes is expressed as number of trials

Flexibility is assessed by using the "Sit and reach test". Here the distance between the tips of the fingers in the start to the final positions during this trunk flexion is recorded. The best result of two trials is considered the outcome.

Mobility is assessed by using the "Timed Up and Go test". This test involves getting out of a chair, walking 3 meters to and around a cone, and returning to the chair in the shortest time possible. The best score of two trials is recorded.

Maximal oxygen uptake (Vo2 max) is assessed using the "2km Walking test " We perform the test based on the guidelines of the Afisal-Inefc Battery. For this purpose, a circuit is designed, is also used stopwatch (portable digital brand Oregon Scientific®, model SL929 Hockenheim Nero) with a precision of tenths of a second (0.1 sg) and heart rate monitors (Polar RS800 CX) to measure the heart rate at the end of the test. Procedure: The caregivers with comfortable clothes and shoes walk as fast as possible they could without running. Interpretation of the results: The time used to travel is recorded 2 kilometers, the heart rate corresponding to the end of the test expressed in beats per minute. If you spend more than 22 minutes completing the this test loses its validity. To calculate de maximal oxigen uptake (Vo2 max) this formula is used: Vo2max ( mi· kg·' ·min·' ) = 116,2 - 2,98*(time) - 0,11*(heart rate) - 0,14 (age) - 0,39*( body mass index)
