![]() The elbow joint consists of the humerus, radius and ulna bones. Pectoralis major and anterior fibers of deltoid The actions occurs as you then move your arms in front of you Latissimus dorsi and posterior fibers of deltoidįrom the starting position, lift your arms out to the side. ![]() The action occurs as you then move your arms out to the side. ![]() Also, anatomical position requires the shoulders to be in external rotation.įor the start postion, lift your arms in front of you. This action at the shoulder can occur when your arm is in different positions (flexion, abduction, etc.).įrom a position of internal shoulder rotation, rotate your arm so that the elbow faces backward. Latissimus dorsi, teres major (“little lat”)įrom the anatomical position, rotate your arm so that the elbow faces forward. Return (lower) your arms from shoulder flexion or lift your arms behind you Pectoralis major, and anterior fibers of the deltoid What the Action Looks Like (Try It Yourself!) Many actions occur at this ball-and-socket joint. The glenohumeral joint-commonly referred to as the shoulder joint-consists of the attachment of the humerus bone to the scapula. Here, we will look at the muscles that move the arm at the shoulder, elbow, and wrist joints. We then started breaking down each body part, with the last blog looking at the muscles that move the scapulae. In an earlier blog, we looked at how to study anatomy. Below, watch Jennifer Dodson discuss the treatment of shoulder impingement in a short clip from her MedBridge course, Treatment of Shoulder Impingement.As a fitness professional and an exam candidate, there is no way of getting around the fact that you need to know your anatomy! Understanding how the body moves and creates movement with the muscles is a huge part of the job. Regardless of which setting you practice in and the population you serve, my course, Treatment of Shoulder Impingement, will provide you with a variety of exercise techniques to fit the unique needs of your patients and your setting. Learning which exercises are the most effective and recommending them when appropriate will help get your patients back to their meaningful occupations using their upper extremity. The literature supports therapeutic intervention in those who have been diagnosed with shoulder impingement and notes the importance of addressing the scapula. This study leads to the recommendation of effective alternative exercises that don’t require a prone position: Mike Cricchio and Cindy Frazer 4 published a narrative review of electromyographic studies for scapulothoracic and scapulohumeral exercises. But what if you work with a population who are unable to tolerate prone exercise or don’t have the means to replicate these exercises outside of a therapy session? While exercises performed prone are often highly effective, they can’t be performed by everyone, and this can result in low carryover at home. You may have noticed that many of the exercises listed are meant to be performed in a prone position. Prone Row Alternatives for Those Who Can’t Perform Prone Exercises Prone horizontal abduction at 90 degrees abduction with external rotation.Prone External Rotation at 90 Degrees Abduction Prone horizontal abduction with external rotation.Prone external rotation at 90 degrees abduction.So what are the best individual exercises to accomplish these strengthening goals? We’ve broken them down by the specific muscles they target: Choosing Exercises to Target Shoulder Muscles Thoracic extension posture and exercisesĪlisha Fey and her research team 3 also noted the important roles played by the serratus anterior, the lower trapezius, and the middle trapezius in producing scapular upward rotation, posterior tilting, and external rotation of the scapula.Serratus anterior strengthening or retraining.Ludewig and Reynolds go on to suggest the following interventions for SAIS: Greater compensation from the upper trapezius.Paula Ludewig and Jonathan Reynolds 2 demonstrated that, compared to healthy shoulders, shoulders with impingement present the following differences: A customized exercise plan will help with this, but with all the scapular exercises out there, which are going to be the most effective when it comes to strengthening periscapular muscles? What Does the Literature Say?Ī systematic review conducted in 2004 by Lori Michener, Matthew Walsworth, and Evie Burnet 1 looked at the effectiveness of rehabilitation for patients with Subacromial Impingement Syndrome (SAIS) and found that strengthening the scapular stabilizing muscles was preferable to no treatment. One of the goals for treating shoulder impingement is more normalized movement.
