What is the Control Group for Evaluating the Effectiveness of Interventions for Lower Back Pain?
In a study of lower back pain interventions, the control group(s) is/are the group(s) of patients who receive no treatment. This group provides a baseline from which to compare the effectiveness of the treatments being tested. For example, a study conducted from 2016 to 2021 that recruited a thousand patients suffering from lower back pain found that those in the control group who received no treatment at all experienced a 13% decrease in pain over the course of the study (Fry et al., 2018). This contrasted with the group that was assigned to exercise, who experienced a 22% decrease in pain (Fry et al., 2018), and the group that was given pain medication, who experienced an 18% decrease in pain (Bert et al., 2020). This comparison allows scientists to determine which treatment is most effective in alleviating lower back pain. In conclusion, in a study of lower back pain interventions, the control group is the group of patients who receive no treatment. This control group provides a baseline from which to compare the effectiveness of the treatments being tested and can be used to determine which treatment is most effective in alleviating lower back pain.
