One limitation of the effectiveness of NPT on PWD is the difficulty of carrying them out in the real environment where the PWD and caregivers are [
2]. Sometimes it is only possible to do so in specialized centers and almost always is a burden for the caregiver, aggravating the negative consequences that their own care entails, such as the deterioration of the mental health, poor social support and the decrease of leisure time [
28]. Of the interventions offered to CG of patients with dementia, the interventions are predominately psychosocial [
2,
29]. One of the recommendations that should be done is to increase the time they have for themselves, since making pleasant activities is a proven method to improving one’s mood [
30]. It is therefore important to identify which activities you wish to participate in and to make a detailed list of the activities that can be increased, noting when they will take place. Pleasant activities are not only extraordinary activities like going on vacation to a far away place. They can actually be performed daily (reading the newspaper, knitting, talking with a friend on the phone, visiting friends, etc.). Additionally it is known that one of the disadvantages that the CG encounters when attempting to carry out rewarding activities is that it can be impossible to separate themselves from the patient while they are carrying out their duties [
28]. On the other hand, it has been observed that it is difficult for some caregivers to make the decision to carry out pleasant activities when these activities do not directly affect the improvement of the status of the family member whom they care for [
30]. A consequence of this is that the CG of PWD, when compared to non-caregivers, participate in less PA [
31], show increased cardiovascular risk [
32], have an increased risk of hypertension [
33], and suffer more frequently from CVD [
34,
35]. Although these problems can be associated with the state of chronic stress related to the care, and the difficulty in expressing emotions [
36], there is no doubt that they are closely related to PA restriction [
30,
37]. Von Kanel and col. have observed that caregivers, who reported high levels of PA, had a cardiovascular risk score similar to non-caregivers with the same level of PA [
38]. These results suggest that if they increase the levels of PA, the CG could decrease their cardiovascular risk to that of the non-caregivers. It is therefore necessary to evaluate the effectiveness of carrying out interventions that encourage PA for CG of PWD [
38]. In addition to assessing the degree PA of the caregivers, it seems necessary to develop interventions that specifically contribute to the increase of their PA. However, it is not easy to find interventions that have managed to increase the PA in adults, which thus would make it possible to reduce the high proportion of sedentary subjects that are in Spain. It is estimated to be 75% [
8]. At the community level, a Cochrane review in 2008 concluded that there is no sufficient data to support the hypothesis that the community interventions from the multiple components effectively increase the levels of PA of the population [
39]. Some RCTs developed in the field of Primary Health Care have achieved positive results, but this was only seen with the help of PA professionals or educators, and the family doctor. There was an increase of 9.7% in PA for the intervention group with the “green prescription” [
40]. Other results have had discrepancies between men and women [
41], and if it appears to be effective in the increasing PA of the elderly [
42]. Within the framework of the European year 2012, the year of active aging and intergenerational solidarity, the HAPPIER study (Healthy Activity &Physical Programs Innovations in Elderly Residences) was initiated to be developed in elderly residences. However, there is more evidence that all patients with chronic illnesses should be refered to a rehabilitation program that includes an intervention of PA [
43]. Since chronic illness is stable, it seems reasonable that it should be managed in Primary Health Care and coordinated as a regular practice. The program has been initiated into the PACE-Lift in UK in order to determine the feasibility and effectiveness of a Primary Health Care intervention with a pedometer to increase PA among older patients [
44]. Our research program has participated in the project “Multi-center Evaluation of the Experimental Promotional Program of Physical Activity” (PEPAF) [
8], from a sample of 5,000 subjects which were selected randomly from the population consultant in Primary Health Care of six Spanish provinces. The intervention was carried out in Primary Health Care centers and has been effective in increasing the level of PA among inactive patients [
8]. Controls for PA were increased to 18 minutes per week [95% 6–31 min/week]; with an increase of the METS/hour week of 1.3 [95% Cl, 0.4 2.2]. But what is most important in relation to this new project is that the effect of the intervention was particularly positive in people older than 50 years [
8], therefore it could be appropriately applied to the PWD and their CG. On the other hand, in older adults there seems to be a linear relationship between the level of activity and health outcomes, not only among the sedentary, but also among those who walk more than 12,000 steps per day [
45]. Our study incorporates a particular perspective in respect to the gender differences, since more than 70% of the caregivers are women, these usually present a greater osteoarthritis, which makes them less possible to carry out PA [
30].
