Trial Outcomes & Findings for Pulsed Electromagnetic Fields for Post-Amputation Pain (NCT NCT05392803)

NCT ID: NCT05392803

Last Updated: 2024-09-19

Results Overview

The numeric rating scale is a 0-10 Likert scale measuring pain level with 0 = no pain and 10 = worst imaginable pain scale. The outcome will be the difference between the baseline and Day 28 timepoints.

The Brief pain Inventory (short form) is an instrument specifically designed to assess pain and its impact on physical and emotional functioning. The brief Inventory is comprised of three domains: (1) pain, with four questions involving "worst", "average" and "current" pain levels using a 0-10 numeric rating scale \[we are not using\]; (2) percentage of relief provided by pain treatments with one question \[we are not using\] and, (3) interference with 7 questions involving physical and emotional functioning using a 0-10 Likert scale \[0=no interference (good); 10=complete interference (bad)\]: general activity, mood, walking ability, normal work, relations with other people, sleep and enjoyment of life. This outcome will include the interference subscale: 0=no interference (good); 70=complete interference (bad)
