Data Source Information

  1. Data is confidential and was collected through the VA Office of Research and Development.
  2. Sample size: 50 participants enrolled, and 47 veterans randomized after screening.
  3. Data description:
  • The data was collected through clinical trial.
  • Participants were randomized into TRUE CES treatment (N=24) or SHAM placebo (N=23) groups and assessed the measurement at baseline, 6 weeks and 12 weeks.
  • Outcome Variables:

    • Pain levels (Defense and Veterans Pain Rating Scale, DVPRS): the measurement of pain scale ranging from 0 to 10 (0 represents “no pain” and 10 represents “severe” or “worst pain”).

    • Sleep quality (PROMIS t-scores): The questions include Pain, Cognition Function, Sleep, Fatigue, Physical Function, Overall Global Health, Emotional Distress served as supplement. Lower t-score represents better sleep quality.

Impact and Importance

This dashboard provides a visual summary of the effects of Cranial Electrotherapy Stimulation on pain and sleep outcomes among veterans, informing clinical decision-making and supporting the use of CES as a non-invasive therapy option.

Pain Score

Scatterplot

Key Takeaways from Scatterplot:

  1. The Sham CES (No Stimulation) group appears to have a negative trend, suggesting that higher usage may be associated with a greater reduction in pain.

  2. The Active CES (Alpha-Stim) group (blue) shows a slight positive trend, indicating that increased usage does not consistently lead to a larger reduction in pain scores.

  3. The change in pain score does not show a strong correlation with total device usage time for either group.

Sleep Quality

Boxplot: Sleep Quality by Group and Time Point

Key Takeaways from Box Plot:

  1. We can find that there are two notable outliers observed at time point 2:
  • One from the Sham CES group with a t-score of 77.5.
  • One from the Active CES group with a t-score of 46.7.

  1. Lower sleep quality t-score indicates better sleep quality. The Active CES group shows a decreasing median T-score, indicating improved sleep quality (T1: 61, T2: 59.55, T3: 57.20).

  2. Within the Sham CES group, the median t-score shows a decreasing trend (T1: 62, T2: 58.15, T3: 58.10). Additionally, at time points 1 and 3, the median sleep quality t-score is higher in the Sham CES group than in the Active CES group. However, the Active CES group demonstrates greater improvement in sleep quality compared to the Sham CES group.
