Facial nerve dysfunction (facial paralysis) manifests in various symptom patterns. To objectively describe facial function, clinicians use a number of standardised scales - the most common being the House-Brackmann facial nerve grading system. Symptoms of facial nerve injury may vary due to age, facial anatomy and the extent of nerve-damage. 1. What are the differences between functional muscle testing and manual muscle testing? MMT is the most commonly used method for documenting impairments in muscle strength. Manual muscle testing engages range of motion activity and resistance. FMT measures and rates your ability to engage in and perform activities required for daily living Chapter 6 Testing the Muscles of the Lower Extremity Hip Flexion Hip Flexion, Abduction, and External Rotation with Knee Flexion Hip Extension Hip Extension Test to Isolate Gluteus Maximus Hip Extension Tests Modified for Hip Flexion Tightness Supine Hip Extension Test Hip Abduction Hip Abduction from Flexed Position Hip Adduction Hip External Rotation Hip Internal Due to the widespread use of Free Functional Muscle Transplant (FFMT) around the world to reanimate the paralysed face, it is important to be aware of ethnic differences in facial movements. Look for asymmetry at rest, during conversation and when testing various muscles. Ask the patient to wrinkle his forehead or raise his eyebrows, enabling you to test the upper face (frontalis). Next, have the patient tightly close his eyes. Test the strength of the orbicularis oculi by gently trying to pry open the patient's upper eyelid. Strength of Individual Muscle Groups Printer Friendly. Patterns of weakness can help localize a lesion to a particular cortical or white matter region, spinal cord level, nerve root, peripheral nerve, or muscle. Test the strength of each muscle group and record it in a systematic fashion. Chapter 1 Principles of Manual Muscle Testing The Grading System Overview of Test Procedures Criteria for As
