Hypothesis

Does non-invasive interactive neurostimulation (InterX) reduce acute pain in patients following total knee replacement surgery?

Conclusion

The study found that patients receiving InterX therapy experienced significantly lower pain levels and improved range of motion compared to those receiving standard care.

Supporting Evidence

  • NIN therapy reduced pain scores by a mean of 2.3 points.
  • The control group only experienced a mean decrease of 0.34 points in pain.
  • Patients in the experimental group achieved necessary range of motion for discharge faster than the control group.

Takeaway

Using a special device called InterX helps people feel less pain after knee surgery, making it easier for them to move around.

Methodology

A randomized controlled trial with 61 patients undergoing total knee replacement, comparing standard care with additional NIN therapy.

Potential Biases

The randomization process may not have fully accounted for baseline differences in pain and range of motion between groups.

Limitations

Some subjects were excluded due to missing data or confounding conditions, which may affect the generalizability of the results.

Participant Demographics

Patients aged 50-80 with knee joint disease, excluding those with certain medical conditions.
