Background: Informal caregivers of post-stroke patients usually undergo high levels of pain and stress and have a reduced quality of life.; Objective: To evaluate the effectiveness of two home ergonomic interventions aimed at reducing pain intensity and perceived stress and enhancing the quality of life in informal caregivers of chronic post-stroke patients.; Methods: A randomized single-blind controlled clinical trial was conducted, with a sample of 33 informal caregivers of patients with stroke. Three groups were included: one received postural hygiene training and kinesiotherapy, for 12 weeks, two days a week, one hour per session; another received adaptation of the home environment, and the third was a control group. Pain intensity, stress level and general quality of life were evaluated at three-time points: pre-intervention, post-intervention, and after a follow-up period of three months.; Results: Neck pain decreased in the two experimental groups, and increased in the control group. Pain in the shoulders and knees was alleviated in the group that received postural hygiene and kinesiotherapy. In addition, regarding quality of life, this group obtained an improvement in the physical health dimension, while the home adaptation group reported improved social relationships.; Conclusions: These results suggest that 12 weeks of training in postural hygiene, combined with kinesiotherapy, and home adaptations can reduce pain and improve several aspects of the quality of life of this population.
