Comparison of measurement properties of the P4 pain scale and disease specific pain measures in patients with knee osteoarthritis

Abstract

P4 should be used to measure pain in patients with knee OA. It had acceptable measurement properties which is comparable to more widely used pain measures. WOMAC-pain shared a factorial structure with WOMAC-function indicating these measures might be capturing the same construct, questioning its validity to measure pain separately from function. ICOAP had acceptable properties. More work should compare pain measures in less severely affected OA populations.

Ultrasound-Guided Percutaneous Peripheral Nerve Stimulation: Neuromodulation of the Femoral Nerve for Postoperative Analgesia Following Ambulatory Anterior Cruciate Ligament Reconstruction: A Proof of Concept Study

“…This proof of concept study lacked a control group following the initial 10-min treatment period within the recovery room; and, therefore documentation and quantification of analgesia delivery and opioid sparing require additional investigation. However, the reported pain scores and oral opioid requirements of the current feasibility study are dramatically lower than published controls; and, the specific type of reconstruction included in our study-utilizing a patellar autograft-frequently produces more pain than alternative techniques (20,21). The significant potential opioid sparing is particularly noteworthy given the current opioid epidemic and desire to replace opioids as the main postoperative analgesic modality (22).…”

“…The mean (range) implantation time for individual leads was 11 (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25) min, which included equipment setup for any second lead attempt. However, because five subjects had multiple lead insertions, the mean (range) overall treatment time for each subject was 15 (10-32) min.…”

A comparison of muscle activation and knee mechanics during gait between patients with non-traumatic and post-traumatic knee osteoarthritis

“…Height was measured with a measuring tape and mass using a force plate. Participants completed the Intermittent and Constant Osteoarthritis Pain Scale (ICOAP) 14 . This pain scale (11items, 5 point scale) includes subscales for intermittent and constant pain with each subscale converted to a 0e100 score (higher scores ¼ greater pain).…”

Combining mussel with fucoidan as a supplement for joint pain and prediabetes: Study protocol for a randomized, double-blinded, placebo-controlled trial

“…The Musculoskeletal Health Questionnaire (MSK-HQ) contains 14 items and will be used at baseline and at Day 100 to measure pain severity, physical function, and quality of life ( 29 ). Pain will also be measured on Days 0, 30, 50, and 100 using the 4-item pain intensity measure (P4), which measures pain intensity over the past 2 days ( 30 ).…”
