Use of Lumbar Motion Monitor to Predict Response to Radiofrequency Ablation After Medial Branch Diagnostic Blocks
Use of Lumbar Motion Monitor (LMM) as a Prognostic Tool to Predict Response to Medial Branch Radiofrequency Ablation After Medial Branch Diagnostic Blocks
Study Overview
Status
Conditions
Detailed Description
The current standard of care to determine the success of lumbar medical branch block(s) (MBB) is highly subjective, even if clinicians were to use validated questionairres. Currently, there are no studies that use a validated objective functional outcome measure to practically and efficiently assess lumbar MBB success prior to radiofrequency ablation (RFA). The addition of a validated objective measure of functional impairment to the current standard of care may help us improve in identifying the patients that will benefit from lumbar RFA. It has the potential to minimize procedures of limited benefit with a significant impact on containing healthcare spending. Additionally, it may further knowledge on how to appropriately select patients without relying on the stringent double block diagnostic technique put forth by the CMS that may exclude patients who could greatly benefit from a lumbar RFA.
As the objective measure the study will use a lumber motion monitor (LMM). The LMM weighs less than 5 pounds and fits on with a shoulder harness and belt. The LMM measures motion in all three directions (forward back, side to side, and twisting) just like the spine. The LMM testing may take up to 30 minutes depending on how many tasks can be performed by the participant and how many practice trials are required. The LMM testing includes bending forward and back to upright as fast as possible; comfortably while maintaining a twist position.

Change in functional performance probability P(n).
Time Frame: collected at time points Day 1; Weeks 2,4, and 6; and Months 3,6, and 9
|
The Lumbar Motion Monitor (LMM) is an objective, validated, reproducible and accurate tool to rapidly assess the degree of impairment with a sensitivity and specificity of 92% and 97%, respectively.
This device provides a functional measure of trunk range of motion, flexion velocity, extension velocity, flexion acceleration, extension acceleration and compares recordings to a normative database.
The LMM is able to provide an overall impairment score known as a "functional performance probability(P(n)).

Validated as a measure of pain.
Widely used and mandated through the Department of Veterans Affairs as a pain assessment tool.Use of the NRS for MBB and RFA success is the current post procedure assessment standard of care and widely used nationally and within the Ohio State Spine Center clinics.
