Block 1_MuscleEnergy Flashcards
Is Muscle Energy a direct or indirect technique?
Direct.
Is Muscle Energy active or passive?
Active.
What is the general theory behind Muscle Energy?
Essentially the sensing body (spindle) is set different than the muscle. It should be the same as the muscle so that it can send appropriate afferent signals. So, we’re resetting the spindle to match the muscle. Decrease muscle spasm by having the patient isometrically contract a specific muscle (or group of muscles) which decreases the gain from the gamma efferent system by adjusting the muscle spindle apparatus and reeducating the muscles.
How do you perform muscle energy at the sternoclavicular joint?
Patient is supine. Operator abducts shoulder to 45 degrees while monitoring motion at SC joint. Patient actively lifts arm towards ceiling while operator isometrically resists motion. Hold for 3 seconds. Repeat 3 times (going further each time).
How do you perform muscle energy at the anterior radial head?
Patient is supine. Operator cups patient’s elbow with one hand and grasps patient’s wrist with other. Operator places forearm into pronation. Patient supinates forearm while operator isometrically resists motion. Hold for 3 seconds. Repeat 3 times (going further each time).
How do you perform muscle energy at the posterior radial head?
Patient is supine. Operator cups patient’s elbow with one hand and grasps patient’s wrist with other. Operator places forearm into supination. Patient pronates forearm while operator isometrically resists motion. Hold for 3 seconds. Repeat 3 times (going further each time).
How do you perform muscle energy at a flexed wrist?
This means they do not like to extend. Operator induces wrist extension to engage motion barrier. Patient flexes wrist while operator isometrically resists motion. Hold for 3 seconds. Repeat 3 times (going further each time).
How do you perform muscle energy at an extended wrist?
This means they do not like to flex. Operator induces wrist flexion to engage motion barrier. Patient extends wrist while operator isometrically resists motion. Hold for 3 seconds. Repeat 3 times (going further each time).
How do you perform muscle energy at pectoralis major?
Patient is supine. With the elbow flexed 90 degrees, abduct the shoulder to approximately 90 degrees. Extend the shoulder into the restrictive barrier.
(FINE-TUNING: test extension at varying degrees of abduction to find the most restricted vector of pectoralis major). Ask the patient push their fist toward the ceiling while meeting their force for 3-5 seconds. Repeat 3 times (going further each time).
How do you perform muscle energy at latissimus dorsi?
Patient is supine. With the elbow flexed to 90 degrees, externally rotate the shoulder and cup under the elbow while supporting the patient’s arm. Place other hand on the ipsilateral ilium. Abduct the patient’s arm into the restrictive barrier. Ask the patient to adduct their arm toward their side while meeting their force for 3-5 seconds. Repeat 3 times (going further each time).
