Effect of Muscles Activation on Pain in Early Stage of Total Knee Replacement

Course Outline

1. Introduction

   • Overview of Total Knee Replacement (TKR)

   • Common post-operative complications and pain mechanisms

2. Physiology of Pain in Early TKR

   • Nociceptive and inflammatory processes

   • Role of swelling, stiffness, and neuromuscular inhibition

3. Muscle Activation in Early Rehabilitation

   • Quadriceps inhibition and its impact on pain

   • Early activation strategies (isometric, NMES, biofeedback)

   • Muscle recruitment patterns and functional restoration

4. Evidence-Based Effects of Muscle Activation on Pain

   • Current literature findings

   • Mechanisms: improved joint stability, decreased nociception, circulation benefits

5. Practical Applications for Clinical Practice

   • Early-stage activation protocols

   • Progression from isometric to functional exercises

   • Safety considerations and contraindications

6. Case Study & Clinical Scenarios

   • Application of muscle activation in post-TKR rehab

   • Monitoring patient outcomes and adjusting plans

Course Objectives

By the end of this course, participants will be able to:

1. Describe the mechanisms of pain in the early stage of TKR.

2. Explain the relationship between quadriceps inhibition and post-operative pain.

3. Identify evidence-based muscle activation strategies that reduce pain after TKR.

4. Develop safe and progressive activation-based rehabilitation protocols.

5. Apply clinical reasoning to integrate muscle activation in individualized patient care.
