Lab 10: Shoulder

Lab 10: Shoulder Complete the following activities during your lab class under the guidance of your instructor. Objectives of Lab: • Identify common injuries and overuse conditions that occur to the shoulder. • Demonstrate the application of tapes, wraps, braces, and pads to the shoulder for the purpose of preventing, treating, and rehabilitating injuries. Lab Activity 1: Anatomy and Common Conditions Due to the sensitive nature of these palpations, ensure that your partner has consented and is comfortable with the procedure prior to performing. 1. Look at the model and show your partner the following bones. a. Scapular spine b. Inferior angle c. Superior angle d. Humeral head e. Greater tubercle 2. Identify and palpate the following muscles on your partner. a. Trapezius b. Deltoid c. Pectoralis major/minor d. Rotator cuff (four muscles) 3. Locate the following ligaments on a model. a. Glenohumeral ligament b. Coracoacromial ligament c. Acromioclavicular ligament Lab Activity 2: Prevention of Common Conditions 1. Identify three effective prevention strategies and the associated common conditions related to the shoulder. a. Anterior dislocation (4S) b. AC Joint sprain (AC joint sprain tape) c. Clavicular fracture (Clavicle brace) Lab Activity 3: Application of Taping, Wrapping, Bracing, and Padding Practice and demonstrate your ability to appropriately apply these techniques with a partner as demonstrated and instructed in class. List one common condition that each of these techniques would be useful with during treatment and rehabilitation. 1. Bracing a. Off-the-shelf shoulder stabilizer Prevents and treats instabilities 2. Wrapping a. Shoulder spica Treats a shoulder pointer b. 4 S (spica, sling, swathe, and support) wrap Treats dislocations 3. Strengthening a. Throwers ten prevention exercises: External and internal rotation at 90 degrees of abduction. i. External and internal rotation at waist ii. Diagonal pattern flexion iii. Diagonal pattern extension iv. Prone rowing v. Prone rowing into external rotation vi. Prone horizontal abduction (neutral, full ER) vii. Shoulder abduction viii. Shoulder scaption ix. Press up x. Push up Lab Activity 4: Case Scenario 1. Javon, a senior linebacker on the local high school football team, suffered an anterior right shoulder subluxation while attempting a tackle during the third quarter of a football game. Upon examination, the diagnosis of the athletic trainer on the field consists of a glenohumeral joint sprain. 2 a. The most common mechanism for an anterior glenohumeral subluxation involves forceful ___abduction______ and _____external rotation_________ of the shoulder. b. Explain what proper initial management of this injury should include. We would immediately immobilize with a sling and refer them to a physician We would also use some ice and and put them in a sling for slight compression c. After Javon has completed 4 weeks of effective rehabilitation, the physician cleared him for return to sport with the use of a brace designed to limit excessive motion. A _________off-the-shoulder stabilizer brace_____________ can be used to provide support and stability to individuals with pathological shoulder laxity who still want to participate in their sport. 2. Ryan, a senior men’s lacrosse player, was diagnosed with a left shoulder AC joint sprain. a. Which mechanisms of injury are most likely associated with this injury? A direct impact to the shoulder forcing the acromion down, back, and in b. Explain what proper initial management of this injury should include. Apply ice and put them in a sling and swathe for compression and stabilization Refer them to a doctor to get a proper diagnosis c. After Ryan has completed 2 weeks of effective rehabilitation, the physician cleared him for return to sport. What techniques as learned in class could be utilized to make the athlete more comfortable during his return to play and why? External and internal rotational exercises to strengthen the shoulder and use padding to protect the area from getting injured further References Prentice, W. E. (2017).
