Electrophysiology

1. Evidence-Based Applications of Electrophysiological Studies in Physiotherapy Detailed Presentation

2. Introduction Electrophysiological studies are key diagnostic tools in physiotherapy, especially for neuromuscular conditions. They assess muscle and nerve activity to support diagnosis, monitor progress, and guide treatment in an evidence-based manner.

3. Types of Electrophysiological Studies - Electromyography (EMG): Needle & Surface - Nerve Conduction Studies (NCS) - Evoked Potentials (EPs) - H-Reflex and F-wave Studies

4. 1. Diagnosis & Localization - Detects neuropathies, radiculopathies, myopathies - Complements imaging (MRI/CT) - Increases diagnostic accuracy significantly

5. 2. Monitoring Muscle Activation - Surface EMG used in stroke, pelvic floor rehab - Supports voluntary control and muscle re-education - Proven benefits in RCTs

6. 3. Prognostic Value - Predicts recovery in nerve/spinal cord injuries - Guides treatment like electrical stimulation - Useful in Bell’s palsy, post-trauma

7. 4. Spasticity Evaluation - EMG differentiates spasticity from rigidity - Tracks effects of botox, therapy, medications

8. 5. Biofeedback in Motor Learning - Improves motor control, posture - Used post-ACL surgery, stroke rehab - Enhances learning via sEMG feedback

9. 6. Pain Management - EMG reveals abnormal firing/muscle imbalance - Helpful in chronic back pain, TMD - Leads to targeted interventions

10. 7. Ergonomic & Gait Analysis - Used for ergonomic assessment & gait training - Valuable in stroke, Parkinson's, orthotic fitting

11. Clinical Examples - Stroke: sEMG biofeedback for arm control - CTS: NCS for grading & treatment planning - ACL Rehab: sEMG for quad activation - Bell’s Palsy: Needle EMG for prognosis

12. Advantages & Limitations Advantages: - Objective assessment - Guides therapy - Tracks progress Limitations: - Requires equipment and training - Some techniques invasive

13. Conclusion Electrophysiological studies enhance physiotherapy by offering accurate diagnosis, prognosis, and treatment guidance. They support individualized care and better patient outcomes through evidence-based application.
