PainVision Apparatus Is Effective for Assessing Low Back Pain

Area of Science:

• Biomedical Engineering
• Pain Medicine
• Clinical Assessment

Background:

• A novel device, PainVision PS-2100, quantifies pain perception.
• Previous research has not extensively evaluated its efficacy for low back pain.

Purpose of the Study:

• To determine the utility of the PainVision apparatus for assessing low back pain.
• To evaluate the efficacy of PainVision in a clinical setting.

Main Methods:

• A case series involving 89 patients with low back pain.
• Pain levels were measured using PainVision, Numeric Rating Scale (NRS), and McGill Pain Questionnaire (MPQ) at baseline and 4-week intervals.
• Spearman's rank correlation test was used to analyze the relationship between PainVision scores and traditional pain measures.

Main Results:

• Strong correlation found between NRS and MPQ scores (rs =0.60, p<0.0001).
• Moderate correlation observed between PainVision-derived pain levels and NRS/MPQ scores (rs =0.40, p<0.03).
• Changes in PainVision scores over 4 weeks moderately correlated with changes in NRS and MPQ scores (rs =0.40, p<0.01).

Conclusions:

• PainVision serves as a useful tool for assessing low back pain.
• The device demonstrates comparable utility to self-reported questionnaires in pain assessment.
