A Prospective Six-Month Study of Chronic Pain Sufferers: A Novel OTC Neuromodulation Therapy

Figure 2

Distribution of pain levels (VAS) in the study sample at the various time points during which data were collected: baseline, 7days, and 3, 4, and 6 months. A shift in distribution from baseline, following initial 7-day PSWT treatment, indicates that most of the pain relief obtained in the first 7 days is maintained over a 6-month period, with continued device use.
