According to the results reported on ClinicalTrials.gov, this trial (NCT05200858) enrolled 30 people in total — 15 in an active treatment group and 15 in a placebo (dummy treatment) group. The trial ran in two back-to-back four-week periods: a blinded phase (where participants did not know which group they were in) and an unblinded phase (where they did know). The main thing the trial was measuring was how much pain interfered with daily functioning, using a standard questionnaire called the Brief Pain Inventory, scored from 0 (no interference) to 10 (complete interference). Secondary measures included pain severity, fatigue, and aspects of walking such as step rate and timing. The reported data shows that during the blinded phase, the active group's pain interference score changed by an average of 0.454 points on the 0–10 scale, compared to 0.198 points in the placebo group. For pain severity (also on a 0–10 scale), the reported average change was 1.184 points in the active group and 0.289 points in the placebo group. Regarding fatigue (measured on a 0–100 scale), the reported change was 2.821 points in the active group and 2.231 points in the placebo group. For the walking measures, the reported data shows the active group took about 1.13 seconds per stride compared to 1.16 seconds in the placebo group, walked at 106.42 steps per minute versus 105.90, and spent about 22.84% of each stride with both feet on the ground compared to 22.64% in the placebo group. Results from the unblinded phase were not reported in the submitted data. These are the results as reported to ClinicalTrials.gov.
