Surface Electromyography in Stratifying Chronic Low Back Pain.

University of Malaya30 enrolled

Overview

Surface Electromyography can be utilised to detect normal muscle electrical activity during maximum forward flexion termed Flexion Relaxation Response (FRR)

In this study, our primary objective is to assess FRR and disability (ODI) correlation protocol as an objective tool in stratifying Chronic LBP. We also would like to evaluate the relationship between FRR with pain intensity and lumbar range of motion as our secondary objective.

Outcomes

Primary Outcomes

Oswestry Low Back Pain Disability Questionnaire

Questionnaire of the functional assessment for the low back pain patient

Representing range of pain intensity from no pain on the far left to most intense pain on the far right.

Time frame: 1 YEAR

Gross Range of Motion

Degree of trunk motion at maximum voluntary flexion, measured by inclinometer at the level of T12

Time frame: 1 YEAR
