Comparing Real-Time and Recalled Ratings of Phantom Limb Pain Intensity.

Area of Science:

• Pain Management
• Amputee Care
• Clinical Measurement

Background:

• Accurate measurement is crucial for evidence-based healthcare.
• Phantom limb pain (PLP) measurement is challenging due to variable pain episodes.
• Current PLP assessment relies on potentially biased patient recall during appointments.

Purpose of the Study:

• To compare recalled versus real-time intensity ratings of phantom limb pain.
• To evaluate the accuracy of standard recalled pain measurements against momentary assessments.

Main Methods:

• Seventeen lower limb amputees participated in the study.
• Participants provided real-time pain intensity ratings via mobile devices three times daily for 40 days.
• Momentary pain ratings were compared to recalled ratings using standard clinical questions.

Main Results:

• Recalled average PLP intensity was significantly higher than average momentary ratings (6.53 vs. 1.99/5.08; p < 0.001).
• Recalled maximum PLP intensity was significantly higher than maximum momentary ratings (9.06 vs. 7.59; p = 0.001).

Conclusions:

• Momentary pain ratings may offer more accurate insights into phantom limb pain intensity than recalled ratings.
• Real-time, frequent pain assessments can enhance clinical tracking and treatment evaluation for PLP.
• Integrating ecological momentary assessment can improve the management of phantom limb pain.
