In a single-blind clinical trial on 50 nurses with chronic back pain, subjects were randomly allocated to two groups: an experimental (acupressure) group and a sham group.
For each patient in the experimental group, acupressure techniques were performed during nine sessions, three times a week, for 14 minutes. In the sham group, only points within 1 centimeter of the main acupressure points were touched. Data was collected using the Fatigue Severity Scale (FSS) before the session and immediately after, two weeks after, and four weeks after the intervention.
Patients in the acupressure group reported a significantly lower mean score of fatigue severity compared to the sham group immediately after, two weeks after, and one month after the intervention.
