The purpose of this study was to evaluate whether using flotation tank therapy could reduce chronic, stress-related muscle pain. It did this by tracking changes in physical pain surface area. The researchers used the Pain Area Inventory (PAI)—a tool for patients to map pain on a body diagram to measure changes in pain location and size before and after regular, supervised flotation sessions.
This study utilized a randomized controlled trial (RCT) design, assigning a small sample of 32 patients (29 women and 3 men) with chronic, stress-related pain to either a treatment group receiving 12 flotation-REST sessions over six weeks or a control group. While the random assignment provides a strong, reliable methodology to reduce bias, the small sample size and skewed gender distribution result in low generalizability, limiting the application of these findings to a broader population.
Flotation-REST therapy resulted in a statistically significant reduction in stress-related chronic pain, with treatment group pain area scores decreasing from a mean of 60.94 to 40.07. Conversely, the control group experienced a slight increase in pain, with their average pain area score rising from 46.59 to 54.22. Additionally, participants reported significant decreases in anxiety, stress, and depression, along with reduced blood pressure.
This study once again shows that flotation therapy offers a scientifically validated, drug-free alternative for individuals seeking to manage chronic pain, stress, and burnout, as studies indicate it physically reduces pain areas rather than providing mere distraction.
