Surface Electromyography in Stratifying Chronic Low Back Pain.

Completed

• Conditions: Low Back Pain
• Interventions: Procedure: Surface Electromyography

• Registration Number: NCT04960358
• Lead Sponsor: University of Malaya

Brief Summary

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

Detailed Description

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.
